Excellent 5 stars

Had windows fitted last week by Mansat Windows, overseen by the owner Mits. I was extremely impressed with how professional the company dealt with the complete process, excellent quality, and at a very competitive price. I have dealt with many glazing companies over the past few years, but I would have no hesitation in recommending this particular company. I will definitely be returning on any future projects I am involved in. John Leigh

Good job!

Very pleased with my windows and doors fitted by Mansat. They worked professionally and obviously know their business. Very helpful if you have questions. They worked in a timely manner and also clean up after themselves.

Double glazed windows fitted. Excellent job.

So pleased with my three new windows, all fitted in less than a day by a polite and professional team who were fully focused on the task in hand. They carefully maintained social distancing while working to a high standard of craftsmanship. When the work was finished the company cleared away all the broken old windows too and left the house and garden spotless. Would definitely use them again in the future. Thanks for doing such a good job.
