Frequently asked questions

No, new windows are generally not required as we can provide an upgrade service where the existing window/door frame is kept and we only replace the moving sections.

We generally use Sapele, which is a very good natural hardwood. We also have a Engineered Redwood range available as well as Accoya and other timbers.

We offer 50 years on Accoya wood, 30 years on Sapele hardwood, 10 years on draught proofing, and up to 15 years on glazing.

Only if the window/door is completely replaced in an existing opening with no changes as set out by FENSA.

All of London postcodes but we sometimes travel to other areas of the country for regular customers.

Lead times are generally between 10-14 weeks year round but please ask for an up-to-date lead time.

We are in North London and have a few small workshops. Our office address is just off of the Holloway Road, but this is not manned.

Yes, we do as part of our overhaul and draught-proofing service. We can carry these out separately but this is not as cost effective.

Yes, we carry a full range of insurance in the unlikely event of requiring them.

Yes, we work with small and medium builders on a weekly basis.

Yes. Properties located within designated conservation areas generally fall under Article 4 Directions, which strip away standard permitted development rights for external alterations. Replacements must ordinarily utilize matching timber and faithfully replicate the original glazing bar patterns, profiles, and opening mechanisms. It is highly advised to seek local authority approval or obtain a Certificate of Lawful Development prior to commencing any physical works.

Sapele is a dense, highly durable natural African hardwood prized for its interlocking grain and inherent resistance to rot and fungal decay. Accoya, conversely, is an engineered softwood that undergoes a patented acetylation process, altering its molecular structure to physically reject moisture absorption. While Sapele will reliably perform for decades, Accoya offers an exceptional lifespan exceeding 80 years and features virtually zero volumetric swelling or shrinkage.

The draught-proofing process involves machining discrete, precision grooves directly into the timber sashes, meeting rails, and outer frames to house high-performance brush pile seals. These integrated seals close the perimeter gaps that cause wind rattles and cold drafts, effectively reducing structural heat loss by up to 50% without requiring the capital expense of a full window replacement.

Yes. All complete replacement window installations strictly comply with modern UK building regulations regarding thermal insulation (Document L) and safety. Upon the completion of a full window replacement project, a certified FENSA certificate is issued to the property owner alongside a comprehensive, insurance-backed guarantee.

Acoustic double glazing utilizes varying, asymmetric thicknesses of glass paired with a specialized sound-damping polyvinyl butyral (PVB) interlayer to physically disrupt incoming sound waves. This specific configuration is highly effective against low-frequency traffic rumble and high-frequency flight path noise, reducing external sound penetration into the living space by up to 45dB.

In standard London conservation areas, like-for-like timber sash replacements are classified as permitted development, meaning they do not require formal planning permission, provided the new units perfectly replicate the original design, materials, profile dimensions, and glazing patterns. However, if your property is covered by an Article 4 Direction, normal permitted development rights are removed, and you must obtain Householder Planning Permission even for identical timber replacements. Flats also lack permitted development rights, although boroughs like Kensington and Chelsea have introduced specific Local Development Orders (LDOs) that permit double glazing in non-listed flats without planning consent, provided they match the original timber material.

Sapele is a natural tropical hardwood native to West Africa with a Class 3 durability rating and high density, offering excellent impact strength and superior screw retention. Accoya is an engineered softwood (Radiata Pine) that has undergone a chemical modification process called acetylation. This process converts water-attracting hydroxyl groups into hydrophobic acetyl groups, rendering the wood structurally stable and virtually impervious to water absorption. While Sapele represents an exceptional and cost-effective natural hardwood choice, Accoya achieves a Class 1 durability rating with a 50-year warranty, though it requires stainless steel fixings to prevent the residual acetic acid from corroding standard metal hardware.

Yes, this is one of the most significant advantages of vacuum-insulated glazing (VIG). Because FINEO measures a mere 6.7mm to 7.7mm in thickness, it easily replicates the narrow profile of traditional single glazing and can be retrofitted directly into existing narrow historic timber rebates. This allows homeowners to preserve and restore their original timber frames and sashes while upgrading the thermal performance to a U-value of 0.7 W/m²K (equivalent to bulky triple glazing) and reducing sound transmission by up to 34% compared to single glazing.

A traditional counterbalance system utilizes cast-iron, lead, or steel weights suspended from waxed cotton sash cords over solid brass pulleys housed within the hollow pockets of the outer timber box frame. This is the only acceptable mechanism for strict historic restorations and listed buildings, as it preserves the original depth of the reveals. A modern spiral balance system replaces the weights and cords with pre-tensioned, spring-loaded steel cartridges integrated directly into the window frame. This allows for a much narrower, compact box profile, which is ideal for modern extensions or where physical masonry space within the reveals is highly restricted.

Security is a key priority in our manufacturing process. All our bespoke sash windows are constructed using robust, stable timbers and can be fitted with advanced multi-point locking mechanisms integrated with traditional ironmongery. We offer toughened or laminated security glass options (complying with BS EN 1279), dual-position restrictor locks that prevent the window from being opened past a safe limit from the outside, and heavy-duty brass locking fitch fasteners. This ensures your period property remains highly secure without sacrificing its classic heritage appearance.

Yes. The bespoke timber windows are engineered precisely to satisfy local conservation requirements. The design process replicates original features, including section sizes, deep bottom rails, slim meeting rails, and traditional muntin profiles. By working directly with local planning authorities across London, approval is obtained without unnecessary delay.

Sapele is an exceptionally dense, natural hardwood (640 kg/m³) with an interlocking grain that offers great strength and natural durability. Accoya is an engineered softwood that undergoes an acetylation chemical modification process, converting hydrophilic hydroxyl groups into hydrophobic acetyl groups. This process provides Accoya with superior dimensional stability, making it practically immune to swelling and shrinking.

Yes. LSWD offers a specialized retrofitting service. If the original box frame is structurally sound, new double-glazed timber sashes can be manufactured and fitted directly into the existing box lining. This process preserves valuable internal plasterwork and architraves while upgrading the property to modern thermal standards.

All complete replacement timber windows are manufactured to exceed Part L of the building regulations, achieving U-values as low as 1.2 W/m²K to 1.4 W/m²K with slim heritage double-glazing. High-grade neoprene weather seals are integrated around the sashes to block drafts, reducing perimeter air infiltration by up to 95%.

Thanks to the advanced, multi-coat microporous paint system applied in a temperature-controlled environment, the paint is highly flexible and expands naturally with the wood. This prevents cracking, blistering, and peeling, resulting in a maintenance cycle of approximately 8 to 10 years before requiring a simple, light sand and topcoat.

Untreated softwood sashes in London conditions last 80–120 years before major intervention. With regular maintenance and modern protective coatings, service life extends beyond 150 years.

Sticking or rattling sashes, visible gaps at the meeting rail, frayed cords hanging inside the frame, and increased dust on sills all indicate imbalance or wear.

No. The brush or pile strips sit inside the existing beads and are invisible once the sashes are closed. The external appearance remains identical.

Yes. Heritage slimline units (total thickness around 14 mm) fit into rebated sashes or new sashes fabricated to match originals, preserving sightlines and complying with conservation requirements.

Specialist acoustic glazing and heavier sashes routinely achieve 40–44 dB reductions, turning heavy traffic noise into a distant murmur.

Repairs and like-for-like replacements usually fall under permitted development. However, listed buildings or conservation areas require formal consent for any material change or double glazing.

Expect £350–£650 per window for draught proofing, cord replacement, and balancing. Full refurbishment including timber repairs and redecoration ranges £650–£1,200 per window.

Accoya offers superior dimensional stability and rot resistance for painted finishes. Sapele provides richer grain and natural durability if a stained or oiled finish is preferred.

Exterior faces every 5–7 years; interior faces every 8–10 years. Micro-porous coatings extend these intervals by allowing the timber to breathe.

Yes. Draught proofing and heritage double glazing typically raise the window component score enough to lift the overall rating by one or two bands, directly affecting energy bills and future lettability.

Yes — we can design windows that comply with local conservation rules and liaise with planning departments on your behalf.

We typically use durable, stable woods treated for long life (e.g. pressure-treated redwood, oak, Accoya). We can also discuss alternative timbers if preferred.

Some maintenance (painting, sealing) is needed, but with our finishes and protective measures, it’s minimal and much less frequent than many think.

Yes — if the frames are still sound, refurbishment is often possible and more economical. We’ll always suggest the most suitable route for your windows.

If your property is covered by an Article 4 Direction or falls within the Dulwich Estate Scheme of Management, you will generally need planning permission or estate management consent to replace windows on front-facing elevations. If the replacements are exact replicas in material, profile, sightlines, and glazing details, the approval process is straightforward.

Standard double glazing features an overall unit thickness of 24mm to 28mm with wide spacer bars, which requires thick, heavy timber profiles. Slimline double glazing measures between 11mm and 14mm thick with ultra-slim sightlines, allowing it to fit into historic sash profiles while matching the thermal performance of thicker units using advanced insulating gas fillings.

A standard installation for a complete house of 4 to 6 windows typically takes between 2 and 3 working days. This timeline includes removing the existing frames, structurally securing the new boxes, insulating the perimeter reveals, and applying the final internal architraves and external pointing.

Yes, if your original box frames are structurally sound and free from widespread wet rot, we can perform a sash-only replacement. This process involves removing the old single-glazed sashes, modifying or retaining the original box, and installing new, custom-made double-glazed sashes equipped with modern weather-seals and weighted balance systems.

Modern factory-applied coatings mean you only need to wash down the external timber frames with warm, soapy water once a year to remove surface dirt and pollution. The internal pulley wheels and sash chains should receive a light drop of silicone lubricant every two years to ensure quiet, effortless movement.

Acoustic insulation is achieved through a combination of airtight perimeter compression seals and acoustic asymmetric glazing. By using two panes of glass with different thicknesses within the double-glazed unit, sound waves are disrupted and dampened far more effectively than by standard, symmetrical glazing.

Engineered timber is constructed by laminating multiple sections of wood together with opposing grain patterns. This design cancels out the natural internal stresses of the wood, preventing the window frames from twisting, bowing, or warping when exposed to wet winter weather or hot summer sun.

Yes, installing high-quality, historically accurate timber windows increases the market value of period properties. Prospective buyers in premium areas like Dulwich look for authentic historic features and avoid properties with uncharacteristic uPVC replacements, which often face planning enforcement actions.

Accoya is a sustainably sourced softwood that undergoes a specialized acetylation process. This chemical modification bonds acetyl groups into the wood fibers, preventing them from absorbing water. The result is a highly durable timber that resists rot, remains structurally stable, and carries a 50-year warranty against wood decay.

Window rattling happens when sashes fit loosely within their guide tracks. Modern timber sashes feature machined tracks that house hidden brush piles and compression seals. These components fill the physical gaps around the moving frames, completely blocking cold air drafts and stopping the sashes from moving or rattling in high winds.

Mechanical failure typically stems from unbalanced weights and frayed cotton cords. When the internal pulley system loses tension or alignment, the resulting friction places severe stress on the timber joints, leading to frame distortion and binding.

Accoya undergoes a chemical acetylation process that alters its cellular structure, preventing it from absorbing water. This eliminates the seasonal expansion and contraction that causes standard timber to warp, twist and split over time.

Yes, slimline and vacuum insulated glass units are specifically designed with narrow profiles. They fit perfectly into the rebated sections of original timber frames without requiring bulky modifications that would ruin the historical aesthetic.

Standard glass allows low frequency sound waves to pass through with minimal resistance. Laminated acoustic glass features a special polyvinyl butyral core that absorbs these vibrations, reducing noise transmission by up to 38dB compared to standard single panes.

Factory spray finishing occurs in a moisture controlled environment, ensuring the microporous paint bonds perfectly to the timber. This prevents the brush marks, trapped moisture and uneven coverage that cause exterior paint to peel and crack prematurely.

Concealed perimeter sealing blocks the air infiltration gaps around moving parts. This drastically reduces thermal transmittance and eliminates the cold draughts that cause heating systems to overwork, saving up to 30 percent on winter heating costs.

Planning authorities require new installations to visually replicate the original components exactly. This includes matching the width of glazing bars, the shape of decorative horns and the exact depth of the external frame profile.

Replacing old steel weights with dense cast iron or lead allows for perfect counterbalancing in a smaller cavity. Pairing these with high tensile modern cords ensures smooth, frictionless movement that protects the structural integrity of the joints.

Premium joinery utilizes traditional mortise and tenon joints secured with waterproof adhesives. This method provides maximum load bearing strength and prevents the joints from opening up and admitting water during heavy rain.

Single glazing creates a cold interior surface that attracts airborne moisture, leading to heavy condensation. Vacuum sealed units maintain a warm interior glass surface, which fundamentally stops condensation from forming and prevents subsequent black mould growth on the timber rails.

Basic repairs often utilize standard polyester fillers and cheap softwoods that absorb moisture at different rates than the original timber. When the wood naturally expands and contracts, these rigid fillers crack, allowing water to penetrate deep into the joint, accelerating fungal decay beneath the fresh paint.

Accoya undergoes an acetylation process that fundamentally alters its cellular structure, preventing it from absorbing moisture. This gives it unparalleled dimensional stability, meaning it will not warp, swell, or shrink, and it holds paint significantly longer than traditional softwoods.

Yes, existing frames can often be routed deeper to accommodate heritage slim units. These units use dense gases like Krypton or a vacuum space to achieve high thermal performance while maintaining a very thin profile, usually between seven and fourteen millimeters.

Standard double glass uses two panes of identical thickness, which can actually amplify certain noise frequencies. Acoustic glass uses panes of different thicknesses separated by a specialized noise-dampening PVB membrane, disrupting sound waves much more effectively.

Professional systems involve routing hidden channels into the timber and inserting low-friction brush piles or silicone fins. These flexible seals close the gaps between the moving parts, stopping air drafts and rattling without restricting the sliding mechanism.

Modifications in conservation areas usually require consent. However, using heritage slimline units, matching the original timber profiles exactly, and maintaining the original horn details and sightlines drastically increases the likelihood of approval from conservation officers.

Double-glazed units are significantly heavier than original single panes. The existing cast iron counterweights inside the frame box will be too light to hold the window open. Lead is denser, providing the necessary heavier counterbalance within the tight, restricted space of the original weight box.

Factory-applied microporous paints provide a perfectly even, highly durable coating that flexes with the timber. This application method seals the wood uniformly before it is exposed to the elements, offering significantly longer protection against moisture compared to on-site hand application.

No, complete extraction is rarely required and can damage surrounding plaster and brickwork. Skilled craftsmen can cut away the severely rotted sections of the sill and precisely splice in new, treated hardwood sections, preserving the sound portions of the original box frame.

Secondary barriers involve installing a completely independent, internal glass unit on the room side of the existing window. It leaves the exterior historical window entirely untouched, making it an ideal solution for historic structures where altering the original timber is strictly prohibited.

If you own a house and are replacing like-for-like in timber, you generally do not. If you live in a flat or maisonette, you must apply for full planning permission even for timber replicas.

Accoya is acetylated timber, making it virtually rot-proof and dimensionally stable. It does not swell in winter, meaning your windows will never jam or stick due to humidity.

Yes, vacuum glazing like Fineo is often approved because its 7.7mm profile fits into original sashes, allowing for triple-glazing performance without changing the window’s appearance.

We use asymmetric acoustic glass. By using two panes of different thicknesses, we break up sound waves and prevent the “coupling” effect that makes standard double glazing less effective against traffic noise.

It is a planning tool used by the LBHF council to restrict permitted development rights. It means you must apply for planning permission for alterations that would normally be allowed without it.

A standard restoration including draught-proofing and timber repairs takes approximately one day per window. This includes deconstruction, repair, and recalibration of weights.

All rented properties must reach an EPC Band C by October 2030. Improving window performance is often the most critical “fabric first” step to reaching this target.

No. While timber has a higher initial cost, its 60-year lifespan is triple that of uPVC. Timber also adds 10-15% to property value, whereas uPVC can decrease value in historic areas.

The council can issue an Enforcement Notice requiring you to remove the unauthorized windows and replace them with compliant timber units at your own expense.

In many cases, yes. We can rebate the original sashes to accept slimline or vacuum glazing, allowing you to keep the original historic timber while enjoying modern warmth.

Not always, but often. If you live in a conservation area or your home is listed, you will likely need council approval. For non-listed homes outside conservation areas, like-for-like replacements using identical materials and designs usually do not require permission. However, many parts of Walthamstow, particularly the Village, are subject to Article 4 Directions that remove these rights, so always check with Waltham Forest Council before starting work.

Sash window restoration typically costs between £500 and £2,000 per window, depending on the extent of timber repair and whether draught-proofing is included. Full replacement with a new timber sash window can range from £2,500 to £4,000 per unit, making restoration the more cost-effective option in most cases.

Yes, in many cases. Slim-profile double-glazed units can be retrofitted into existing timber frames without altering the external appearance. This is particularly suitable for Walthamstow homes that are not in conservation areas. For listed buildings, internal secondary glazing is often the preferred solution as it is reversible and does not damage the historic fabric.

Secondary glazing involves installing a second pane of glass or acrylic on the inside of the existing window frame. It is generally supported by conservation officers for listed buildings because it is reversible and does not alter the external appearance of the property. However, Listed Building Consent may still be required depending on the specific installation method.

High-quality timber sash windows, when properly maintained, can last over 100 years. A professional restoration—including timber repairs, re-cording, and draught-proofing—can extend the functional lifespan of your existing windows by 25 to 30 years before further intervention is needed.

The most frequent issues are broken or frayed sash cords (causing sashes to jam or drop), accumulated paint preventing smooth operation, draughts and rattles due to worn parting beads, and timber rot, particularly in the lower sashes and sills where moisture collects.

Yes. Draught-proofing alone improves noise insulation by sealing air gaps. Installing secondary glazing or slim-profile double glazing can reduce external noise transmission by up to 50%, making a significant difference for homes near Walthamstow High Street or busy arterial roads.

If one sash cord has broken, it is advisable to replace all cords on that window at the same time. The cords degrade at a similar rate, and accessing the weight pockets requires removing the sashes. Doing all cords in one visit avoids paying for the same labour twice within a short period.

An Article 4 Direction is a legal instrument that removes certain permitted development rights. In Walthamstow Village and other protected zones, this means you cannot change your windows (even replacing timber with timber) without submitting a full planning application. This is designed to protect the historic character of the streetscape.

Look for companies with specific experience in Walthamstow’s conservation areas and period properties. Check for accreditations such as FENSA certification, membership of the Glass and Glazing Federation, and insurance-backed guarantees. Ask to see examples of previous restoration work on similar local properties, and always obtain multiple detailed quotes before proceeding

If you live in a conservation area—approximately 50% of Islington—you will likely need planning permission to change your windows, especially under Article 4 Directions. Replacement windows must also comply with Part L of the Building Regulations (U-value of 1.2 W/m²K or better from 2025). Restoration and draught-proofing generally do not require permission.

Minor repairs such as cord replacement cost £100–£200. Draught-proofing ranges from £250–£450 per window. Full refurbishment including repairs, re-glazing, and painting typically costs £600–£1,200 per window. Extensive rot repair can reach £1,200–£2,000.

Yes, but you must use heritage-appropriate solutions. Options include slimline double glazing (12–18mm thick) or vacuum glazing (7.7mm thick). Full planning permission is usually required. Secondary glazing, which adds an internal pane, is often the simplest compliant solution.

Draught-proofing can reduce air infiltration by up to 86% and cut heating bills by approximately £60 per year for an average UK household, with greater savings in larger period properties.

Replacement windows must achieve a whole-window U-value of 1.2 W/m²K or better. Single glazing (4.5–5.0) fails. Standard double glazing (2.5–3.0) fails. You will need slimline double glazing, vacuum glazing, or high-performance triple glazing.

Every 5–7 years for most exposures. South-facing or coastal properties may need repainting every 3–5 years. Use breathable microporous paints to allow moisture to escape and prevent rot.

Yes, for new replacement windows installed since June 2022, unless your property is listed or in a conservation area where exemptions apply. For Islington conservation properties, background ventilation can often be achieved through alternative means.

Press firmly on the cill ends and bottom rails with a screwdriver. If the wood feels soft or spongy, decay is present. Other signs include peeling paint, dark discolouration, and a musty smell.

Yes. Vacuum glazing is just 7.7mm thick and provides a U-value of 0.7 W/m²K—better than triple glazing. It is ideal for heritage properties because it preserves the original frame and slim glazing bar profiles. However, it is more expensive than slimline double glazing.

Yes. Several Islington-based specialists offer restoration, draught-proofing, and heritage-compliant upgrades, including Sash Restoration London (based in Islington), MJ Kloss Carpentry, and Tusk Joinery and Restoration. Look for companies with experience in conservation area regulations and listed buildings.

Moisture-swollen bottom rails from failed putty, plus dust-packed pulleys—clear channels and plane rails down 1mm for instant relief.

£1,200-£2,800 per window, factoring scaffolding and FENSA certs; partial retrofits start at £700.

Yes in conservation zones (most of Kensington)—submit heritage statements showing slim profiles match originals.

Possible for confident users: drop weights via pocket holes, knot new 10mm cotton to 1.2kg balances—but pros ensure even tension.

Low-friction brush pile seals in staff bead channels; they flex 2,000 cycles without crumbling.

Tap sills—dull thud means inner decay; chisel test confirms if fibres crush under 3kg pressure.

Yes with 14mm Slimlite units; they preserve 95% of sightlines while hitting 1.2 U-value.

2-3 days per bay, including scaffolding; weatherproof in 4 hours.

8-12% uplift in SW7, per Zoopla data, from EPC jumps and kerb appeal.

10-20 years on timber/glazing, 5 years labour—FENSA-backed for compliance.

No, if you like-for-like repair (same timber, same profile, same glazing bar widths). Yes, if you change the material, the opening method, or the glazing thickness beyond 1mm of original. Always check with Haringey Council’s planning portal before starting.

£750 to £1,450 per window depending on rot level. A basic overhaul (new cords, re-putty, paint) averages £850. Full stile replacement and draught-proofing averages £1,200.

Yes. Magnetic secondary glazing starts at £120 per window. But it reduces the sash opening depth. For original flush sashes, you need a slim profile secondary frame (max 18mm depth). Otherwise the sash handle will hit the secondary panel.

Cotton cords: every 10–12 years. Nylon cords: 15–20 years. Signs of failure: fraying at the pulley wheel or a “gritty” feel when lifting the sash.

Absolutely not. Foam expands and jams the weights. Use mineral wool batts or closed-cell foam sheets cut to size. Leave a 20mm air gap behind the weights for movement.

A two-part microporous system: one coat of alkyd primer + two coats of waterborne acrylic topcoat. Brands: Bedec MSP or Teknos. Avoid standard gloss—it cracks under UV and traps moisture.

No. It means the staff bead is loose or the weatherstripping is compressed. Add a bead of flexible silicone to the inside edge of the staff bead, or replace the pile strip with a thicker 6mm nap.

Yes, but matching the timber profile is hard. You will need a bespoke routing of the bottom rail to match the original’s moulding. Expect 6–8 weeks lead time from a specialist joinery shop.

That is a sign of failed parting bead seals. Remove the staff bead, lift out the inner sash, and replace the flexible seal on the parting bead. Also check that the trickle vents (if fitted) are not blocked.

Properly maintained Accoya or oak sash: 50+ years. Standard softwood sash with good paint: 25–35 years. uPVC sash (non-heritage style): 10–15 years before fading, warping, or weld failure.

Yes, professional transport services utilize heavy-duty vehicles with secure strapping systems and padded interiors specifically designed to handle oversized, fragile architectural components without causing mechanical degradation.

Experienced moving teams conduct structural assessments to navigate narrow stairwells and tight corners. They use specialized lifting harnesses and dismantling techniques to ensure heavy hardwood frames reach upper floors safely.

Professional collection and delivery services can coordinate phased deliveries. This allows your frames to remain safe from moisture and weather damage until the installation team is ready to fit them.

Yes, clearance and waste removal services handle the immediate extraction and responsible disposal of all old fenestration materials, keeping your site safe and eliminating the need for expensive, unsightly skips.

Logistics experts utilize impact-resistant wrapping, edge protectors, and localized bracing to absorb road vibrations, preventing the hermetic seals of double or triple glazing from fracturing during transport.

Rented vans lack specialized air-ride suspensions and secure internal battening. Without proper load distribution, lateral forces during turns can warp the mortise and tenon joints of the timber, permanently ruining the frame’s alignment.

Absolutely. Reliable transport providers schedule highly accurate delivery windows, ensuring materials arrive exactly when your tradespeople need them, eliminating costly unplanned downtime.

Yes, nationwide and European removal services manage the long-haul transit, customs coordination, and final-mile delivery for joinery sourced from overseas manufacturers.

Yes, packing and dismantling support services can break down oversized units into manageable segments, protecting the hinges, tracks, and timber from structural torsion during the journey.

Professional logistics providers carry comprehensive goods-in-transit insurance. This guarantees that in the highly unlikely event of an incident, the full replacement value of your bespoke timber investment is financially protected.
