Ron & Ginny, Waterlooville

We are really very pleased with the (30!) windows you have installed for us and will recommend you to our friends. The key thing for us was immediate response to any problems and the friendly (and patient) attitude from everyone throughout.

Libby, United Kingdom

We had 5 very large VELFAC windows fitted to the front of our house. The team was very friendly and efficient and the results are wonderful. The work was completed to a very high standard and was carried out with very little inconvenience. We highly recommend.

Mike John, United Kingdom

In late 2017 we moved into a new house with VELFAC windows and doors. 5 years later we were experiencing some issues with both windows and doors needing service/repair. The distributor appointed by VELFAC to carry out the adjustments was Wescott Construction. A price for the work was agreed and the 2 engineers thought they would have their work cut out to complete in the day. However they worked speedily and efficiently, explaining what they had done and advising me on future maintenance I could carry out. We were most impressed by their caring courteous approach [disability issues] We would not hesitate in recommending this Firm to others for their quality & reliability.
