As experts in listed, conservation and period properties, we specialise in bespoke timber sash windows and casement windows for architecturally sensitive properties, including windows for Victorian, Edwardian and Georgian homes. 

In 31 (and counting!) unique planning authorities across London and the Home Counties, we have been able to fulfil the strict planning criteria needed for windows and doors on conservation and listed buildings. We help you through the entire process from planning approval through to design, survey, manufacture and installation. 

From small one-off projects to large scale redevelopments, our heritage windows combine elegant, precision design with modern performance – including our Timbalite slimline double glazing units, that look just like single glazing, but offer optimum thermal and acoustic performance.


With slender profile sections, fine mouldings and slim glazing bars, we specialise in authentic, delicate heritage windows which include a range of understated solutions for modern security and performance needs. Some of the key benefits and features you can expect include:

  • Exact-match section sizes, profiling and mouldings
  • Full replacement or new sashes/ casements fitted to the existing frames
  • Glazing options including acoustic glass, restoration glass, thermally efficient single glazing or high performance slimline double glazed units
  • Choice of the finest stable timbers, such as Accoya, which won’t swell or warp
  • Hand-puttied or timber beaded
  • Hand painted or full factory spray finish with high performance microporous paint
  • Choice of traditional high performance hardware and fittings
  • Full range of specialist restoration and draught proofing services
  • Full design, supply and install service

We can also reglaze or replace windows with our thermally efficient single glazing, ‘Solo‘, which is 38% more effective at thermal insulation than single glazing.  


At Timbawood, our specialist heritage style windows and doors are all made by hand in our West London factory by our skilled joiners, using the finest timbers, paints and glazing. We offer the full range of services for conservation area properties, including full replacement, part replacement and a range of repair, restoration and refurbishment services for timber windows.
