New Door Install - A Superb Service Experienced Throughout
This is my third time of using Seal-Lite and the service received is second to none from sales, survey and installation. The Team have been outstanding throughout and the installation Team took great care and carried out the install to a very high standard.
I would have no hesitation in recommending Seal-Lite as they have been outstanding each time that I have used them.
A huge thanks to the entire team for a great service, and a special thanks to the installation team also as they really do a superb job.

Would have been 5 - design, build, the lads doing the work, all was excellent. However, communication wasn’t great, especially around timing of third party contractors arriving. Otherwise all brilliant

Fitting crew were polite avoided making any mess and cleared up when finished. The weather was changeable over the days fitting was carried out and the fitters did listen to my advice to work around the weather.
The glazing is so efficient that this is the first time I have seen condensation on the outside of the outside pane of glass.

Dear Sir, Thank you for your fantastic review and for choosing us! We’re glad to hear that our fitting crew was polite, mindful of keeping things tidy, and adaptable to the changing weather.

If you ever need anything else, please do give us a call.

Fair price and excellent service
We had all our windows and double opening doors replaced in a large conservatory kitchen over 3 days for a very reasonable price - more than £3.5k less than a big national competitor. All the planning, surveying and fitting was carried out in a very professional and careful manner, we were consulted and listened to at all times about any finishes, and the room was left clean and tidy at the end of each day. We are delighted with our new windows and very happy with the fair cost and careful installation. We have had all our windows replaced by Seal-Lite over the last 25 years and are very happy with the quality.

Seal Lite sealed the best deal for us
After being very disappointed by the two largest double glazing companies with very poor service we have had our misplaced trust fully restored by Seal-Lite Group. From initial inception of fact based discussions rather than sales talk about double and triple double glazing we gradually moved distrust to being fully confident about how a very competant company would deliver an excellent product in a timely manner. The installation of all front windows with triple glazing was performed carefully with an eye to detail to finishing touches and cost around half of what other large companies wanted to charge us. Special thanks to Kevin and Steve our very professional fitters from Seal-Lite. We have no hesitation in fully recommending this company.
