We had double glazed windows, new doors and cladding installed by this company. The work quality has been terrible with several call backs to try and rectify the work. The front door has leaked several times and again last night hall was flooded. The front window had to be changed after hairs found inside glass. The company failed to insulate correctly behind cladding and had to come back several times to try and sort problems with this, the cladding has now bowed due to poor installation. Work started November 2020 and we still have problems. They have tried to blame manufacturers, however, after recent inspection by a manufacturer it was found the door frame was twisted and not fitted correctly. The Window Centre do not use their own fitters and contract the work out. Recommend you do not use this company. We thought we could trust them with being Which? Trusted Traders. I have had to put a completion date in to submit this review, however, work is not complete. There are still many repairs required.
