I couldn't recommend this company more, they strive for perfection and understood the urgency of my problem. Not only did they fix my initial problem they realigned my doors . Thank you Zak I would recommend you to all I know

I suffered more than a decade with a problem with my wide heavy aluminium/glass balcony door in my flat that was sagging and scraping on the sill, and numerous tradesmen coming to assess it, none of whom were able to solve it. One even referred me to a company to replace the entire frame system for the door and surrounding windows for over £4k! Thermalseal were able to visit and identify the problem immediately. They faced several surprises that required much additional time, and they stuck at it relentlessly in the tiring heat, no extra charge. The problem is now fixed and fixed well!

Fixed and serviced windows. Provided additional year warranty in addition to standard.

Excellent service. Turned up on time. Price as quoted. Time taken as said. Very pleasant people. Thoroughly recommend and would use again

Needed old UPVC door replaced. Excellent work! I had a hole in my wall that they explained they did not usually cover but would also do to help me out at no extra cost. They Disposed of the old door and made sure no mess was left. Communication throughout was excellent and arrived on time as discussed. Highly recommend the boys at Thermalseal for excellent service and a reasonable price.

The boys kept me informed at all times when they would be arriving and what needed to be done with regards the alignment , workmanship was excellent and such nice guys. Would highly recommend.
