I’m so pleased that we chose Seal-Lite to replace our windows and door. We had 14 windows and our kitchen door replaced and I am truly delighted with the finished product. From the quotation process to the professional installation team it was faultless, excellent communication throughout the whole process. I thoroughly recommend Seal-Lite.

Everything was excellently controlled by the company.
Everything went to plan. When there was a slight problem they identified it, arranged to rectify it and completed the project perfectly. No one asked for any money until we were completely satisfied. Would use them again.

Fantastic service from this company and…
Fantastic service from this company and their installer, Andy, in particular.
Andy completed two jobs for us, a replacement sealed window unit in our lounge and an external trickle-vent to the Annexe. Both jobs completed by Andy without fuss, with no mess and minimal inconvience to us and, most important of all, a smile on his face! Excellent service!

To start, you produce a very good product, first person we met was Paul Davis, he measured to get a quote for us he was very polite and talked about what we wanted and put us right where we were unsure. Fitting team was Paul and Ryan, a very good install, very clean and tidy explained everything we needed to know. Would recommend your firm to anyone.
