How we work
Before anything is measured for a quote, we read the house: original profiles, movement in the frame, what a century of paint has hidden. That assessment tells us whether repair or replacement is right for your home.
Sapele or Accoya timber, traditional sash boxes and slim double glazing where it suits. Cut, joined and finished in our own North London workshop. Not flat-packed, not imported.
Hidden draught seals, weights and cords, beaded putty lines and bespoke paintwork finished to the highest standard. Close up, the difference is obvious.
A good restoration feels at home on the street, with the original character intact and a warmer room behind the glass.
What we make
Everything below is drawn, made and finished in our workshop, then fitted by our professional on-site team.
Most windows are only ever seen from the street.
Ours are made to be lived behind. Look at what changes when the right hands get to work.
Case study · North London
This project showcases a full-scale architectural upgrade, featuring the complete installation of custom windows, doors, and a small, elegant orangery. Built for modern performance without sacrificing character, the entire installation integrates high-performance double glazing and expert draught-proofing.

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 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.
