London Sash Windows Prices

We are London Sash Window specialists that pride ourselves in producing the highest quality product and service, we have listed a pricing structure below to use as a guide.

Overhaul and draught proofing:

The price starts at £262.50 Inc Vat for our standard service to a timber framed sash window. This is our basic system but provides a window improvement of around 30% - 40%. Space tolerance is required

around the sash window to allow free movement within the box frame. However this equates to around a 4 - 5 inch or 100mm - 125mm hole in the center of the window! The draught proofing system minimises this space using our brush system, which also reduces noise by 6db - 10db.

New Double Glazed sashes into existing frame:

The price starts at £500 Inc Vat and this price would be in addition to the overhaul and draught proofing of the original sash window frame. The sashes are manufactured from high quality Sapele Hardwood and glazed with heritage slim double glazed units. The unit depth starts at 12mm (4mm glass - 4mm gas [Argon or Krypton) cavity - 4mm glass) or we can increase the cavity depth up to 8mm to improve the performance of the unit but this is subject to the existing sash thickness. The sashes can come either primed, undercoated or fully finished (hand painted or spray finished).

Acoustic noise reducing glass:

The price starts at £500 Inc Vat and this price would be in addition to the overhaul and draught proofing of the original sash window frame. The sashes are manufactured from high quality Sapele Hardwood and glazed with 6.8mm, 8.8mm, 10.8mm or 12.8mm acoustic single glass. This will help reduce noise from road traffic, air traffic, general background noise and train pollution. This type of glass reduces noise between 34dB and 40db depending on the thickness of the glass and inter-layer. This type of glass can also be incorporated into a double glazed unit giving high noise reduction and energy efficiency.

Details can be found HERE.

Secondary Glazing:

This price starts at £250 Inc Vat. Secondary glazing can be a great way to improve the energy efficiency and noise reduction of a primary window and it also reduces dirt ingress. We manufacture & install special hardwood secondary glazing that is very slim & discreet. We offer this with a fully hand painted or sprayed finish. We also offer aluminium secondary glazing for areas that can not accept a timber framed equivalent. Either option can be glazed with single float or sheet glass or an acoustic single glass. To maximise the improvements, we would always recommend having the primary windows & doors upgraded first with a draught proofing system, if possible.

Details can be found HERE.

Repairs & Painting:

Repairs and painting are priced on a per item/job basis as each set of works needs to be assessed individually. During this process many different materials and items are required to carry out the service. We will itemise any repair works we find during a survey and this will be included in our personalised quote to you but should the repair not be required upon commencement of the works, we will omit this and you will not be charged. We can offer painting services as a part of our package, alternatively the client can outsource this to a local decorator to help reduce the budget where possible.
