Thermaglaze Wales

We had a new front door fitted. Service was excellent from start to finish . Leighton was fantastic helping chose the right door for us. Would highly recommend .

After having a few quotes from different companies, we were in no doubt about choosing Thermaglaze as they were much more knowledgeable and informative about their products without using any pushy sales tactics, and their quote was by far the best! All involved have been super friendly and helpful and the installation team did an expert job installing 3 lovley quality sash windows quickly and efficiently, all done in just a few hours. We love our new windows and will definitely be using Thermaglaze again! We highly recommend them!

Excellent company with a 5 * service. Their representative was on time and was extremely helpful and friendly. We were given a date for installation, the fitters arrived on time and were quick friendly and very clean . They cleaned all the mess and took our old door away for recycling. My husband and I are extremely pleased not only with the service but the quality of our new front door. Highly recommended

We’ve been incredibly impressed with Thermaglaze and couldn’t be happier with the work they’ve done on our conservatory conversion. They replaced all of the windows and installed a brand‑new roof with a lantern, completely transforming the space from a room that was too cold in winter and too warm in summer into a comfortable, usable room all year round. From start to finish, the project was handled brilliantly. The price was competitive, communication was clear, and the team who carried out the work were hardworking, efficient, polite, and tidy throughout. They completed everything to a very high standard, including finishing the inside of the room, and removed all waste once the job was done. We would highly recommend Thermaglaze to anyone looking for conservatory, window, or door work.

Very happy with the new bifold doors, excellent service & fitting. Installers were professional and everything left clean & tidy. Will definitely use again.

Thermaglaze recently installed French doors on our garage as part of an office conversion, and they were brilliant from start to finish. They offered the best quote, were friendly, and never pushy at any stage. The salesperson was great, the surveyor measured up quickly with no fuss, and the installation team had the doors fitted perfectly within a few hours. The finish is fantastic, and all the guarantee paperwork was provided straight away. Every member of the team was friendly, professional, and easy to deal with. If you want a trustworthy company that delivers quality work, I wouldn’t hesitate to recommend Thermaglaze.

We recently had Irish Oak windows and Rich Red composite doors fitted by Thermaglaze Wales and we are extremely happy with the whole experience, from quote to after service support. Alan provided excellent pre-sales support, answering all queries and helping us chose the perfect style to complement our home. His attention to detail and genuine care made the decision process smooth and reassuring. When fitting, Gareth and the team were punctual, respectful, and highly skilled. They worked efficiently and left everything clean and tidy, with the finished result looking fantastic. The work was top quality and the windows and door have completely transformed the look and feel of our house. Thermaglaze even arranged for the alarms to be re-fitted to the new doors and for the system to be retested, a very appreciated extra touch. We would recommend Thermaglaze to anyone looking for high-quality windows and doors, at a great price and with superb customer service.
