It was a complete pleasure to deal with this company. I only had a small repair job but the service was outstanding from start to finish. They bent over backwards to accommodate my busy schedule and the service was friendly and professional from both the office and the guys on site. I would highly recommend.

We had our Windows installed in 2017 by Test Valley. Since then we have been very pleased with the quality of the windows and their performance in terms of keeping the heat in and sound deadening from the road in front of the house. Recently we had a problem with one of the window handles. We contacted Test Valley and they promptly sent out their engineer who replaced the part under warranty. Excellent service. Would highly recommend.

This is the second conservatory we have had built by Test Valley. The service and work provided was exceptionally good. We knew where we were from start to finish. Any questions were answered immediately and concisely in the knowledge that the information was sound. The finished result was beyond our expectations and we would recommend Test Valley Windows for any conservatory work, or indeed windows.

Fitted windows in wrong rooms. School boy error they say. Maybe should look at your drawings and photos to confirm you are doing things correctly. Communication not great over christmas break they send out emails but no one there to pick up and confirm fittings and changed day of fitting without informing us. Would not recommend and will be looking elsewhere to have downstairs windows and doors changed.
