Bespoke Timber Sash Window Installation in Caterham , Surrey

If you are carrying out like-for-like timber repairs, you usually do not need formal planning permission. However, if you plan to change from single glazing to double glazing in an Article 4 conservation area or a listed building, you will likely need consent. Charlie Burgess can advise on local planning trends in Wandsworth, Richmond, and Lambeth to help your project stay compliant.

Our system involves machining hidden brush seals into the new parting and staff beads. We also install seals along the meeting rails where the two sashes join. These seals close the gaps that let in cold air and dust, but they are completely invisible when the window is closed, meaning your window’s authentic profile is never compromised.

Yes, we often perform sash double-glazing upgrades. If your existing box frames are in good condition, we can manufacture new timber sashes fitted with argon-filled double glazing and install them into your original frames. This saves you the cost of a full replacement while providing the thermal benefits of modern glass.

A snapped cord can make a window dangerous or impossible to open. We replace old cords with heavy-duty, wax-impregnated cotton cords. During this process, we also open the pocket pieces to check your lead or iron counterweights, ensuring the sash is perfectly rebalanced for a smooth, easy glide.

All our new bespoke timber window installations come with a comprehensive 10-year guarantee. This covers the integrity of the timber joinery and the performance of the double-glazed units. Because we are FENSA registered, you also have the assurance that the installation meets all professional trade standards.

Absolutely. Rot usually starts at the sill because that is where water sits. We use a method called splicing, where we remove the soft, decayed wood and rebuild the sill using durable timber. Once primed and sealed, the repair is seamless and prevents future water ingress from reaching the internal structure of your home.

We offer same-day emergency call-outs for broken glass, dropped sashes, or snapped cords across South West London and Surrey. This service is available from Monday to Saturday, 08:00 to 18:00. We will secure and weatherproof your window immediately, with permanent joinery work scheduled shortly after.

Charlie Burgess will visit your property to carry out a physical assessment of your frames, sills, weights, and glass. He will look for structural issues and take precise measurements. Following this, you will receive a clear, fixed written quotation so you know exactly what the work entails before any timber is cut.
