 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.

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.

Why is Secondary Glazing an Outdated Solution for Listed Buildings?

Many homeowners ask us to remove their secondary glazing and reglaze the original sashes with vacuum glazing, and there is a good reason for this.

Aesthetics – Some people feel secondary glazing looks unattractive from the outside or inside. Extra glazing bars and panes of glass can alter the look of your home.

Reduced natural light – Secondary glazing creates another layer between you and the outside, which can marginally reduce the amount of natural light coming into a room.

Extra cleaning – You now have an extra layer of glass that needs cleaning and maintenance.

Cramped Window Operation and Reduced Space: Secondary glazing can make operating the original windows difficult and awkward. The extra framework also takes up valuable space.

The benefits of reglazing your original windows with VIG glazing.

Benefits of reglazing your original wooden windows with thin-profile vacuum-insulated glazing units.

Installing double glazing into existing wooden window frames allows the original aesthetics and charm to remain while modernizing the windows’ energy efficiency and performance.
Thin vacuum-sealed glass units provide excellent thermal insulation and noise reduction. It is as efficient as standard triple glazing.
Over 90% of our applications are approved.

Custom vacuum-insulated glass units can be manufactured in unique shapes and sizes to match the varied designs of historic wooden window frames.
Vacuum-insulated glass (VIG) double-glazing units have an exceptionally long lifespan compared to regular double-glazing.
Unlike secondary glazing, windows reglazed with double glazing will function just like new double-glazed windows.

Cost considerations

The reglazing of typical sash windows with toughened vacuum insulated glass (VIG) double glazing, draught-proofing, and restoration of the frame and sashes costs approximately £1500-1700 per window on average.

This is comparable to or even less expensive than high-end listed building secondary glazing.

However, VIG double glazing provides all the benefits of modern thermal performance and noise reduction while retaining the original appearance.
