September 2017 – We chose Tri-Tec Windows following recommendations on Facebook and we were not left disappointed. From quotation stage to installation the whole team were professional, efficient and friendly. There is no hard sell, prices are very competitive and the quality of the product is excellent. We would definitely use this company again!

Liz Ellen


Tri-Tec supplied and fitted all the windows and doors in our extension. From the quote stage to the installation and after-care stage they have been excellent. We would have no hesitation in recommending them. We will definitely use them when it comes to replacing the existing windows in the original part of the house.
