01

How Our Draught Exclusion System Improves Your Windows

Our draught-proofing method involves precision joinery that addresses the common gaps found around sliding sashes. We machine high-performance brush seals directly into new timber parting and staff beads. This creates an effective, hidden barrier against the elements, ensuring a consistent seal around the window perimeter. By sealing the meeting rails and frame gaps, we significantly improve the thermal performance of your home while allowing the sashes to glide smoothly as they were originally intended.

02

Full Overhaul and Mechanism Restoration

Draught proofing is more than just adding seals; it requires a complete check of the window mechanics to ensure longevity. During the process, we assess the condition of your box frames and sash stiles. We replace worn-out cords with durable, wax-impregnated cotton sash cords and carefully rebalance the existing cast iron or lead counterweights. If we find areas of rot, particularly in the sills or lower boxes, we use precise timber splicing with seasoned wood or Accoya to strengthen the frame before the new seals are installed.

Why Choose Professional Timber Preservation in Sevenoaks and Swanley?

Our approach prioritises repair over replacement, ensuring that your property remains compliant with local heritage standards.

"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."

Timber Draught Exclusion Advice

Frequently Asked Questions

Technical guidance from Charlie Burgess on comprehensive draught-proofing, perimeter sealing, and sash restoration across South London.

How does timber sash window draught proofing actually work?

+

At Eden Sash Windows, our approach focuses on making your original windows airtight without losing their period charm. Charlie Burgess and the team machine subtle grooves into the new timber parting beads and staff beads. We then fit high-quality brush seals into these channels. These seals close the gaps around the sash stiles and meeting rails where cold air usually whistles through. Because the brushes are integrated into the timber components, they stay hidden, preserving the authentic profile of your Victorian or Georgian joinery while stopping rattles and heat loss.

Will draught proofing help reduce street noise in my South West London home?

+

If you live near a busy transport corridor like the A3 or Battersea Park Road, you likely deal with significant ambient noise. While draught proofing is primarily about energy efficiency, the brush seals also act as an acoustic barrier. By sealing the physical gaps that allow sound waves to travel into your rooms, we can noticeably dampen the hum of London traffic. For homeowners looking for even greater silence, we can discuss upgrading your existing sashes to carry double glazing during the restoration process.

Can you draught proof original Victorian sashes without changing how they look?

+

Yes. This is a priority for properties across Wandsworth, Lambeth, and Richmond conservation areas. Our draught-proofing system is designed to be invisible when the window is closed. We don't use stick-on plastic strips or bulky add-ons. Instead, we replace the old, worn beads with matching timber sections that house the seals internally. This maintains the delicate sightlines and traditional putty lines that define period architecture, keeping your home warm while satisfying strict heritage requirements.

Do I need planning permission for draught exclusion in a London conservation area?

+

For most properties in South West London and Surrey, draught proofing and timber repairs are considered maintenance and do not require formal planning permission. Even in Article 4 areas like the Shaftesbury Park Estate or Clapham Manor, like-for-like repairs that retain the original box frames are usually encouraged. If your project involves a full replacement or a shift from single to double glazing in a Grade II listed building, Charlie Burgess can provide technical guidance on what the local authority in Merton, Kingston, or Elmbridge typically expects.

What happens if my sash cords are snapped or the window is stuck?

+

A draught-proofing service is the perfect time to address mechanical issues. When we overhaul your windows, we replace snapped or frayed cords with heavy-duty wax-impregnated cotton sash cords. We also open the weight pockets to check the lead or cast-iron counterweights. If the sashes are painted shut or heavy to lift, we rebalance the weights and plane the timber stiles to make sure the window glides smoothly. You get a window that is easy to operate and completely weather-proof.

Is it possible to draught proof and repair a rotten window sill at the same time?

+

We often find that the lower parts of the window—the sill and the bottom of the box frame—have suffered from water ingress. Rather than replacing the whole unit, we can perform a timber splice repair. We cut away the decayed softwood and rebuild the section using seasoned timber or durable Accoya, bonded with high-strength epoxy resins. Once the structural repair is complete, we install the draught-proofing system, creating a window that is solid, secure, and energy-efficient for years to come.

How long does it take to draught proof a standard sash window?

+

Most projects across Battersea and Wandsworth take about half a day per window for a full draught-proof and overhaul. This includes removing the sashes, fitting the seals, replacing the cords, and rebalancing the weights. We work internally and take great care to protect your floors and furniture. Because we are an independent specialist based in SW8, we manage our schedule to minimise disruption, making sure your home is secure and weather-tight by the end of each day.

What is the benefit of choosing timber sash restoration over replacement?

+

Retaining your original timber is usually the most sustainable and cost-effective choice. Victorian and Georgian joinery was often made from high-quality, slow-grown heartwood that is far superior to modern mass-produced timber. By opting for a restoration and draught-proofing service from Eden Sash Windows, you maintain the historical integrity of your property and avoid the high cost of total replacement. Our work is backed by FENSA registration for new joinery and a 10-year guarantee on bespoke installations, giving you peace of mind that your period windows are in professional hands.
