Had all windows and bi-fold doors replaced by Hi-spec - see the pictures. Brilliant service from start to finish - Nav provided personal service advising us of our options, and we went for casement windows for the front and standard for the back and bi-fold doors. Fitting by Sandeep and Prince was very high quality - good attention to detail. Would recommend this company....locally manufactured as well so even better to support local and UK companies.

High Spec updated our old double glazed windows with new, replaced a door with a window and replaced a window with a door. The finish was great and the brickwork outside looks lovely. The men that came to fit the windows and doors were professional and tidy and pricing was reasonable and competitive. We will be using the company again when we replace windows at the front of our house.
