Our Customers

    positive review  Best glaze were very professional. The installers produced a top quality finish with no cutting corners. They made sure their work area was neat and tidy by keeping tools and sharp objects safely on my property and in their work vehicle, which was very appreciated due to having young kids at home. The level of finish was nothing less than outstanding! I would definitely recommend them and if needed I would not hesitate in booking more work in with them again.

    positive review  We had Best Glaze install a conservatory with a warm roof along with all our windows and doors in the house. The whole process from start to finish was very smooth and the installation was fantastic. The attention to detail is outstanding, we couldnt be happier with the the service and the product. We cheekily asked if we could have a patio installed around the conservatory as an afterthought and the team worked late and on a weekend to lay it for us. They went above and beyond These people offer a personal touch with a thoughtful team that respects you and your home that clean up after themselves I would highly recommend Best Glaze.

The guys carried out an amazing job fitting our replacement uPVC windows and doors, having a converted barn I don't think we have a straight wall in the house, added to that the original windows had been "strapped" which increased the difficulty in removing them. Innovative ideas ensured that the new windows and doors fitted perfectly and looked "right". The work was carried out with consideration to our home, ensuring that no damage was caused. The work was strategically planned with our input and Jay and Tom were always happy to work on in order to ensure the minimum of disruption to our lives and work areas were always left tidy. I would have no hesitation in recommending them to anyone considering having work done.
Professional workmanship of the highest standard

At first I was apprehensive about not going with one of the main brands, but after chatting with Tom from Best Glaze he put my mind at rest. We decided to have the whole house done in Timber windows as its a stone character building. The lads did a super job cutting the trims around the stone and my windows look fantastic. There was absolutley zero mess which we were pleased about and they cleaned down every day after themselves. 10/10!
Would rate Best Glaze 10/10 – Mr B. Berry
We had Best Glaze fit our whole house with windows and doors, we also had a conservatory with a durabase and unltraroof 380 tiled roof. The whole service was amazing, such a clean and tidy team. We would recommend Best Glaze to anyone looking for a professional, respectful service.
