Highly recommend

Phenomenal! Professional, respectful and outstanding work. Couldn’t recommend this company anymore. Any issues I have with windows or doors, they are the best of the best.

Insulating a double glazed door

Thermalseal UK Ltd did an excellent job fixing all of our windows after they had been poorly fitted, causing heat loss and terrible draughts. They responded quickly, were professional throughout, and kept communication clear and friendly from start to finish. The difference is huge — no more draughts and the house already feels much warmer. Highly recommend their services for anyone needing window repairs or adjustments. We will certainly be using them again for any future related issues.

Window refitting and draught-proofing throughout property

I had a great experience with Thermalseal UK Ltd and would recommend them highly. They were able to operate on my  UPVC windows - resealing it professionally and adjust some of them. Their work was of the highest standard. They are also happy to follow up thoroughly if there are any issues that arise.

Best in the Business

Overall the team did a good job sorting all of the issues we had with a couple of our windows for a reasonable price. 
There were a couple of delays for various reasons which are understandable, but communication around them could have been better but these things happen and the work was completed which is the main thing.

Good team

Excellent communication. Came out priced the job. Confirmed scope and price. Completed the work within a week. Excellent job and service all round. 100% recommended. Well done Zac and your team
