Specialist Timber Sash Window Repair In Westminster.

Spliced timber repair on a period sash window box frame and sill
FENSA Registered Craftsmanship Preserving historic box frames, splicing decayed sills, and renewing sash cords without altering authentic period sightlines.
01

Restoring Victorian and Georgian Box Frames

London homes often feature beautiful Victorian and Georgian sashes that suffer from the effects of time and weathering. Our team addresses common issues such as seized pulleys, snapped sash cords, and decay in the box frame. When timber has rotted, we prefer to splice in seasoned, durable timber or use specialist resin repairs to rebuild the original sill. This approach retains the character of your window while ensuring long-term structural integrity without the need to replace the entire unit.

02

Do You Need Help with Draughts or Rattles?

If your windows are cold, noisy, or difficult to open, our draught-proofing service offers a practical solution. We machine hidden brush seals into your existing staff and parting beads, which effectively blocks cold air and reduces street noise without altering the look of your period windows. By rebalancing counterweights with high-quality, wax-impregnated cotton cords, we restore the smooth glide of the sash so it remains secure and easy to operate.

03

Heritage Compliance in London Conservation Areas

Working within Westminster and wider London requires an awareness of local planning authorities and Article 4 Directions. We specialise in repairs that keep your property compliant with conservation rules, ensuring that your window restoration meets the necessary standards for like-for-like timber joinery. Whether you live in a Grade II listed property or a protected terrace, our focus remains on authentic, heritage-sensitive outcomes that pass strict planning scrutiny.

"We are very happy with Eden Joinery's work: we had a completely new sash fitted, and four sashes fitted into our existing frames. Our windows look fantastic - and no more draughts! Terry and son were courteous, tidy, with competitive rates, and took obvious pride in their work. They went the extra mile to fix a problem with one of our frames, and all windows were finished to a high standard. We would not hesitate to recommend them."

Frequently Asked Questions

Clear answers from Charlie Burgess on traditional joinery repairs, rotten sill splicing, draught-proofing, and conservation standards across South London.

Can my rotten Victorian sash window sills be saved?

+

Many homeowners worry that a bit of soft wood means the whole window needs to go. In most cases, we can save the original box frame. We cut away the decayed timber and splice in new, seasoned hardwood or Accoya. This method, combined with professional sealing and priming, stops water from getting back in and keeps your original frames intact for decades to come.

What should I do if a sash cord snaps or the window feels heavy?

+

A snapped cord is more than a nuisance; it makes the window dangerous to operate. We do not just swap the rope. We open the internal weight pockets, check the lead or cast iron counterweights, and rebalance the entire system. By using heavy-duty, wax-impregnated cotton cords and checking the pulleys, we make sure your sashes glide open with minimal effort.

How do you eliminate draughts without changing the look of my windows?

+

Period properties in South West London often suffer from rattles and cold spots. Our draught-proofing system is virtually invisible. We machine discreet brush seals into new staff and parting beads and fit them around the meeting rails. This closes the gaps that let heat escape and damp air in, significantly cutting down on street noise from busy routes like the South Circular or Battersea Park Road.

Is it possible to double-glaze original timber sashes in conservation areas?

+

Yes. We specialise in fitting ultra-slim, A-rated double-glazed units into existing or new timber sashes. These units use argon gas and low-emissivity glass to provide modern thermal performance while keeping the narrow glazing bars and authentic profiles required by planning authorities in places like the Shaftesbury Estate or Richmond Green. It allows you to stay warm without losing the historic aesthetic of your home.

Do I need planning permission for sash restoration in Wandsworth or Lambeth?

+

If you are carrying out like-for-like repairs or timber restoration, you usually do not need formal planning consent. However, if your property is Grade II listed or falls under an Article 4 Direction, there are specific rules about changing the glass or the timber profiles. Charlie Burgess provides advice on local compliance to help you meet the requirements of your borough or freeholder.

How quickly can you fix a broken sash or cracked glass in South West London?

+

If you have a dropped sash, a burglary repair, or a broken pane that leaves your home exposed, we offer a same-day emergency service from Monday to Saturday, 08:00 to 18:00. We can secure the window, board it if necessary, or carry out immediate glazing repairs across Battersea, Wimbledon, and Kingston. For more complex joinery issues, we provide a temporary fix to keep you weatherproof before booking the permanent restoration.
