From start to finish the service was exemplary with everyone talking to one another. A visit to the show room followed by a site visit followed by a further visit to the show room to firm up on the final details. Date for fitting issued very quickly. Engineers fitting, more than efficient, and left the scene in apple pie order. Could not fault the workmanship, the sales side and the Bi fold itself is top notch.10/10 given to all concerned. Staff at the manufacturing end were in contact throughout. Would like the whole house done by this firm and their products!
