The Express Bi-Folding doors (and windows) we had fitted are a top notch product second to none. After an extensive search for a reliable quality product at an affordable price, we settled for Express. You can of course find 'buy cheap, buy twice' prices, but we wanted a product that was going to withstand the test of time both in style and engineering reliability. We visited the Glasgow showroom and received excellent service from David there. This carried through right to the very end, post fitting, ensuring that we were 100% happy with with the service and product. If you want a superior product which is equal in both German quality, all-round design and precision, backed by a very professional and thorough team, then Express in your no.1 choice.
