March 3, 2024They fitted us in quickly to replace some patio doors, and the man who came to fit them was so friendly and knowledgeable. They look fantastic, really smart, we're very happy with them. Will definitely use them again in the future if needed.

October 3, 2024Absolutely superb, nothing was too much trouble; they went above and beyond to give us exactly what we wanted. They gave me the 'boot room' I wanted, storage for shoes, dogs stuff and loads more. Warm, cosy and dry. Would definitely recommend to anybody, we will certainly be using them again. Can't thank Thermotech enough x

August 3, 2024I used Thermotech to replace a conservatory in March 2022. The quality of the installation has been tested by heavy rain on several occasions and it is completely waterproof. I have now used the company to install nine windows and a patio door. The windows were difficult to remove but this task was completed with minimum damage. The finishing work around the revels is of such good quality that there is no evidence that the windows have been changed. Thermotech is a family run business which supplies quality products at competitive prices. The team take pride in their work and ensure that they get the installation right every time.

October 3, 2024Following a friends recommendation we contacted Karl to get a quote to replace our conservatory polycarbonate roof with glass. He gave excellent advice on the selection of the best grey glass and a good quote for the job, which we accepted. The installation was undertaken by Steve and Andy. They worked hard to complete the job in a day and a half in a tidy and efficient manner. They were polite and considerate all the way through. We now have a new roof which makes the conservatory look modern and up-to-date. It is wonderful to enjoy the conservatory even more than before with a lovely view of the sky, trees and birds. Thanks to Karl, who kept us well advised on the project, and his hard working team, all of whom we can sincerely recommend to do a great job. Looking forward to enjoying what we hope will be a wonderful summer in the comfortable conservatory.
