01

Professional Timber Splicing for Heritage Windows

Our approach to sash window restoration prioritises the longevity of your existing joinery. We address rot caused by moisture ingress, a common issue in our local climate, by carefully removing damaged wood and replacing it with durable hardwood splices. These repairs are seamlessly integrated into the original frame, ensuring a robust finish that stands up to the elements. By choosing to restore rather than replace, you maintain the authentic profile and architectural charm that defines your property.

02

Addressing Structural Decay in Victorian Sash Boxes

Rotten sills and degraded pulley stiles are frequent issues for period villas in Surrey, often leading to draughts, rattles, or windows that no longer glide correctly. We approach these repairs by reinforcing the core structure of the box frame. Our joinery work involves meticulous attention to the parting beads and staff beads, ensuring that every component is aligned and operational. This restoration process effectively eliminates draughts and improves the thermal efficiency of your windows while keeping the original brick reveal intact.

03

Do You Need Planning Consent for Window Repairs?

Many residents in Ashford and the wider Surrey region are concerned about conservation area constraints when upgrading their windows. Generally, like-for-like timber repairs do not require planning permission. However, if your property is listed or subject to specific local planning controls, we provide expert guidance to ensure our restoration techniques meet all heritage requirements. We work closely with our clients to ensure all joinery complies with local standards while delivering the performance expected of modern, high-quality timber windows.

04

During our initial survey, Charlie Burgess will conduct a thorough physical assessment of your frames, sills, weights, and glass. This enables us to provide a fixed, written quotation detailing the necessary repairs before any work commences.

"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."

Box Frame Repair FAQs

Frequently Asked Questions

Expert advice from Charlie Burgess on timber box frame repairs, sill splicing, and sash restoration across South London.

Can you repair a box frame if the sill has completely rotted through?

+

Yes. Rotten sills are one of the most common issues we fix across Wimbledon and Kingston. We cut out the decayed section and splice in a new hardwood or Accoya sill. This is far more cost-effective than a full replacement and protects the rest of the frame from further moisture ingress.

How do I know if my sash windows need a repair or a full replacement?

+

During a survey, we check the "heart" of the timber. If the rot is confined to the sills or the bottom of the sash stiles, a repair is usually the best route. If the entire box frame has lost its structural integrity or has been badly distorted over time, we may recommend a new bespoke timber installation.

Is draught proofing included in a box frame restoration?

+

While it is a separate service, we highly recommend draught-proofing during any restoration. It involves machining hidden grooves for brush seals, which is much easier to do when the sashes are already removed for cord replacement or timber repairs.

Will I need planning permission for timber box frame repairs in a conservation area?

+

Generally, like-for-like repairs do not require planning permission as you are maintaining the existing fabric of the building. However, if you are changing from single to double glazing in a listed building or an Article 4 area, you may need consent. Charlie Burgess can advise you on the specific requirements for your borough, whether you are in Wandsworth, Lambeth, or Richmond.

How long does it take to repair a single timber box frame?

+

Most standard repairs and overhauls are completed within a day. This includes removing the sashes, repairing the timber, replacing the cords, and re-hanging the windows so your home is secure and weatherproof by the evening.

Are your timber repairs guaranteed?

+

All our work is carried out to the highest trade standards. New bespoke timber windows come with a 10-year guarantee and FENSA certification, giving you peace of mind that your investment in your home’s heritage is protected.
