Preserving Heritage Character With Double Glazing.

01

Authentic double glazing for period homes

Our approach to double glazing is designed specifically for heritage joinery. We integrate A-rated, argon-filled double-glazed units into your existing boxes or new bespoke timber sashes. These units are engineered to mimic the slim profiles of traditional single glazing, avoiding the bulky appearance of standard modern units. This makes our service the ideal choice for homeowners in Walton-On-Thames who wish to improve energy efficiency without compromising the architectural sightlines protected by local planning preferences.

02

How does our draught-proofing improve your comfort?

Beyond upgrading the glass, we address the common issues of rattling, sticking, and heat loss inherent in older window designs. During the restoration process, we install hidden brush seals into the parting and staff beads. This subtle modification stops draughts and reduces noise infiltration from outside, all while remaining completely invisible when the window is closed. By sealing these gaps, your home becomes significantly warmer during the winter months, and your sashes will glide smoothly within their frames.

03

Expert timber repairs and FENSA standards

We do not believe in unnecessary replacements. If your window sills or boxes show signs of rot, we use precise timber splicing techniques, involving seasoned hardwood or Accoya, to rebuild decayed sections. This saves the original structure where possible and ensures a long-lasting repair. As a FENSA-registered specialist, we adhere to strict building regulations for all our glazing upgrades. Every new bespoke timber sash we install is backed by a 10-year guarantee, giving you complete peace of mind regarding the quality and durability of our joinery.

04

Book your bespoke sash window survey

Every project begins with a thorough physical assessment of your frames, weights, pulleys, and current glazing condition. Charlie Burgess will visit your home in Walton-On-Thames to discuss your specific requirements, explain the restoration process, and provide a clear, fixed written quotation. There is no pressure and no hidden costs, just honest advice from a specialist who understands the unique needs of period timber sashes.

"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."

Double Glazing & Restoration Guidance

Frequently Asked Questions

Practical guidance from Charlie Burgess on upgrading your timber sashes with double glazing, satisfying conservation standards, and draught-proofing period homes across South London.

Can you double glaze my existing original sash boxes?

 +

In many cases, yes. If your original box frames are in good structural condition, we can manufacture new timber sashes fitted with double glazing that sit directly into the existing frames. This avoids the need for major structural work and preserves your interior architraves and plasterwork. During the survey, Charlie will check for any rot in the sills or pulley stiles that may need splicing before the new sashes are fitted.

Will I need planning permission for double glazing in a conservation area?

 +

Like-for-like timber repairs often do not require formal planning permission, but installing double glazing in a conservation area or a listed building can be more complex. Many councils in Wandsworth, Lambeth, and Richmond now look favourably on timber units that match the original profiles. We can advise you on the specific requirements for your local authority to ensure your upgrade is compliant.

How much of a difference does draught proofing make?

 +

Draught proofing is one of the most cost-effective ways to improve a period home. By installing hidden brush seals, we close the gaps that allow heat to escape and cold air to whistle through. When combined with our double glazing, it can significantly lower your heating bills and almost entirely eliminate the rattles common with older Victorian windows.

What is the benefit of double-glazed units over standard double glazing?

 +

Standard double-glazed units are typically 20mm to 24mm thick, which requires very chunky timber frames that look out of place on a period property. Our double-glazed units use advanced thermal technology to provide similar insulation levels in a much thinner profile. This allows us to maintain the authentic "sightlines" of your windows, ensuring they look like the original single-glazed sashes while providing modern A-rated thermal performance.

How long does the installation process take?

 +

The timeline depends on the number of windows, but a standard room can often be completed in a day or two. We work cleanly and efficiently, ensuring your home is secure at the end of every working day. Because we are based in Battersea, we are local to South West London and Surrey, which allows us to manage logistics and site visits effectively without long delays.
