01

Preserving Heritage Joinery Through Precision Repairs

Georgian window boxes and sashes are significant architectural assets that require specific expertise. Rather than recommending full replacements, we focus on identifying and treating the root causes of deterioration. Our team performs expert timber splicing using seasoned wood or Accoya to replace rotten sections of sills and box frames, protecting the integrity of the original structure. By carefully cleaning pulley stiles and replacing worn sash cords with high-quality wax-impregnated cotton, we restore the smooth, balanced glide that these windows were designed to provide.

02

Integrating Double Glazing into Historic Profiles

Many Georgian homeowners wish to improve thermal comfort without replacing their windows with modern, chunky alternatives. We offer bespoke double glazing solutions specifically engineered for heritage properties. By using low-emissivity glass, argon gas filling, and warm-edge spacers, we can achieve high thermal performance while maintaining the narrow profiles and elegant sightlines of your original six-over-six sashes. This allows for improved energy efficiency that meets modern demands while remaining visually indistinguishable from traditional single glazing.

03

Draught Proofing and Conservation Compliance

Effective draught-proofing is essential for maintaining the comfort of London townhouses, particularly those located on busy roads. Our system involves installing hidden brush seals into the parting and staff beads, which significantly reduces cold air ingress and noise pollution without requiring visible alterations to the window's aesthetic. We are well-versed in the planning constraints within Westminster, including Article 4 Directions and Grade II listed property requirements, and will guide you through the necessary steps to ensure any restoration or upgrade remains fully compliant with local conservation guidelines.

04

Reliable Emergency Sash Repairs and Professional Service

If you experience a snapped cord, broken glass, or a stuck sash, prompt action is required to secure your home. We offer same-day emergency attendance for broken sash glass or dropped windows, ensuring your property is professionally boarded and weatherproofed if a permanent repair cannot be completed on the initial visit. Our services are FENSA registered, covered by 2 million pounds of public liability insurance, and all new timber joinery comes with a comprehensive 10-year guarantee. For expert advice and a written quotation, book your detailed sash survey with Charlie Burgess today by calling 020 7046 0157.

"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, architectural guidance on restoring, draught-proofing, and sensitively upgrading historic Georgian timber sashes across South London.

Do I need planning permission for Georgian sash window repair in a conservation area?

 +

In most cases, like-for-like repairs and restoration of original timber do not require planning permission. However, if you are planning to change single glazing to double glazing in a Grade II listed building or an area with Article 4 directions—such as parts of Wandsworth or Lambeth—you will likely need consent. Charlie Burgess can advise on the best way to approach your local planning authority with conservation-compliant joinery specifications.

How do you repair a rotten Georgian window sill without replacing the whole frame?

 +

We use a technique called sill splicing. The rotten section of the timber is carefully cut away back to sound wood. We then rebuild the sill using matching seasoned timber, which is bonded and sealed to the original box frame. This is a cost-effective way to fix the most common area of decay while keeping the original Georgian window in place.

Can double glazing really look like traditional single glazing?

 +

Yes. The double-glazed units we use are designed specifically for heritage properties. They use narrow cavities and low-emissivity glass to provide modern insulation without the thick timber beads seen on standard uPVC or modern timber units. When fitted with traditional putty lines and authentic glazing bars, they are often indistinguishable from the original single-pane sashes.

What is the benefit of a full sash window overhaul?

 +

An overhaul goes beyond just fixing a single problem. We strip the sashes out of the box frame, sand back years of built-up paint that causes sticking, replace the cords, service the pulleys, and install a full draught-proofing system. It is a comprehensive service that makes old windows function like new while retaining their historic value.

How long does it take to repair a Georgian sash window?

 +

Most repairs, such as cord replacements or draught-proofing, can be completed within a day. Larger restoration projects involving timber splicing or double-glazing upgrades depend on the number of windows, but we always aim to leave the property secure and weatherproofed at the end of every working day.

Are your new timber windows guaranteed?

 +

Every new bespoke timber sash window we install comes with a 10-year guarantee and FENSA certification. This gives you peace of mind that the joinery and the installation meet current building regulations and are built to last.
