"I have used window wise for over 15 years as I know that the product is excellent quality and the fitters are totally professional, experienced, and reliable. The price for the windows was competitive, and my neighbour has commented how impressed he is with the installation. Wouldn't hesitate to recommend Christian and his team."

Part of a wall taken out and back door removed. French doors fitted with integrated blinds

"The two gentlemen that came to fit our doors were really tidy and didn't rush the job. They made good all the plastering that was needed to a high standard. Very happy with the finished result. Will go back to them when I need my house fitted with new windows."

Replacement windows and bi-fold doors.

"I have used this company previously. They are competitively priced but in my opinion the workmanship and fitting is far superior to other companies I have used, They conduct a site survey to ensure the product is made exactly to fit and the fitters were always on time, friendly, clean and 100% trustworthy. Highly recommended."
