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

Professional Sill Splicing and Frame Restoration

Rotten sills and degraded box frames are common in older buildings, yet they rarely necessitate a full window replacement. We use durable timber splicing and precision joinery to remove decayed areas, rebuilding the structure with seasoned timber that matches the original profile. This process ensures the structural integrity of your windows is maintained while avoiding unnecessary disturbance to your home's exterior pointing or interior plasterwork.

02

Smooth Operation Through Expert Sash Cord Replacement

A snapped sash cord or a seized pulley can make even the most elegant window difficult to operate. We provide full sash cord replacement using heavy-duty, wax-impregnated cotton cords to ensure your windows glide smoothly. During this process, we also rebalance your counterweights, ensuring your sashes are perfectly weighted for easy opening and closing, restoring the effortless operation intended by the original craftsmen.

03

Draught Proofing for Quiet and Comfortable Interiors

Period homes in the City Of London often suffer from heat loss and noise ingress through gaps around the sashes. Our draught-proofing system involves machining hidden brush seals into new staff and parting beads. This discreet solution seals the gaps around your meeting rails and stiles without altering the visual profile of your windows, effectively eliminating rattles and cold spots while significantly reducing external traffic noise.

04

How do you ensure conservation area compliance for my windows?

We are highly experienced with the strict conservation requirements and Article 4 Directions that govern many buildings across the City Of London. Our repairs are designed to be sympathetic to the heritage of your property, ensuring like-for-like timber joinery and traditional finishes. By prioritising repair and restoration, we help you meet local planning demands while upgrading the performance of your original windows. We are FENSA registered and provide a 10-year guarantee on new bespoke timber installations, giving you complete peace of mind.

"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.
