 Trustindex verifies that the original source of the review is Google. We're so pleased with how the windows turned out, the refurbished frames look so good. Anecdotally, they seemed to have improved the soundproofing,  although we live practically on top of a main road,  so does not completely shut out the noise, the casement windows more than the bay windows. Cannot comment on the thermal quality as they were done in the middle of the heatwave, but we are fairly confident there will be a big improvement come winter. Cannot fault the workmen, they were reliable and extremely hard working, even when it was 30C +

Would definitely use them again if we ever needed windows to be refurbished in future.

 Trustindex verifies that the original source of the review is Google. Very happy with the new windows they look fantastic.
Keeping the original windows was so important to us and you have made that possible.
We only had the upstairs completed and can't believe the difference in the sound and temperature from downstairs.
Will be booking the downstairs in ASAP.
The team are also fantastic and worked incredibly hard they treated our home with respect and keep evething as clean as they can.
I would definitely recommend.
Hopefully we will get the same team next   time!
The neighbours are also asking who done the work and have commented on how hard you worked !
Very happy customers.

A genuinely reassuring experience from start to finish. If you've got a heritage property and you're agonising over who to trust, look no further. Highly recommended.

 Trustindex verifies that the original source of the review is Google. Scott James did our restoration work years ago, so when it came time to sort the insulation, there was no question who we'd call. Glad to say they're still the same lot. Still doing things properly.
The new VIG glazing has made the house genuinely warmer, and a fair bit quieter too. Lovely to see familiar faces, lovely to see they still take pride in the work. Wouldn't go anywhere else

 Trustindex verifies that the original source of the review is Trustindex. Exceptional sash window restoration experience
We had a great experience having our sash windows double glazed and draught proofed. We were very impressed by the quality of the work and the team’s craftsmanship from the start. From the initial consultation with Alex right through to the restoration of the windows, the experience was seamless. They were clearly experts in their field.

 Trustindex verifies that the original source of the review is Google. The end result genuinely surprised us. The original frames have been brought back to life sanded, restored, repainted and the new glazing has made a noticeable difference to both the temperature and the noise from the road. For roughly what secondary glazing would've cost, we've got something that actually looks like part of the house rather than bolted onto it.

Keep character – boost efficiency

We retrofit vacuum insulated glazing (VIG) directly into your existing timber sashes. This means you keep the original character of your windows, while achieving U-values that outperform current market standards and building regulations.

By meeting – and often exceeding – today’s energy performance requirements, your windows are future-proofed for any upcoming regulation changes. This ensures you won’t need another upgrade down the line, giving you long-term efficiency, compliance, and peace of mind.

The reglazing, combined with refurbishment and draught-proofing, brings a wide range of benefits.

These include soundproofing against external noise, the elimination of condensation and rattling, and, most importantly, significantly improved thermal insulation – keeping the heat in and making your whole house warmer during winter.

Glazing: The King of Thermal Efficiency

It’s very simple – windows are essentially glass within frames. The better the glazing, the better the thermal insulation. Frames also play a role, but getting the glazing right accounts for 80–90% of achieving the desired results.

That’s why we use vacuum insulated glazing (VIG) in all of our projects.

It is widely regarded as the most energy-efficient and durable option on the market.

Glazing that fits original windows

We use ultra-thin 8 mm vacuum insulated glazing (VIG), which slots neatly into most existing timber frames.

This lets you keep the character of your original windows while enjoying top-level energy efficiency.

A comparison chart shows five types of glazing, including double glazing sash windows, by heat retention, thickness, and retrofit suitability, with labeled images and measurements for each glazing type.

Before & After Transformations

All timber frame issues are addressed during the reglazing process. Sashes are rebalanced, new sash cords installed, putty replaced, rot repaired, and new locks fitted.

The end result is original windows that look as though they have just been newly installed – but with the most advanced glazing available on the market today.
