what our clients say..

New composite front door and two double glazed units replaced

“Delighted with the new door and the service from start to finish. Would definitely recommend.”

May 2016

Fitted New Rockdoor and 2 Side Panels in Irish Oak

“More than happy to recommend Dave and his colleague from Fortress UPVC. From start to finish you could not fault them. We are over the moon with our new front door; it looks so much more modern than our old white UPVC one. We opted for Rockdoor Vermont and side panels in Irish oak inside and out with glue chip glass in side panels with Apollo bespoke glazing in the front door, this door is so much nicer and better made than a Solidor front door we went to see from another company. We did not rush our decision which for us was the right move. Great work Fortress, thanks again.”

Install 3 rockdoors, patio door locks and 2 parts of window hinges.

“Excellent workmanship from Dave Martin and his colleague Dave. Fitted 3 rockdors, polite and not rushed in to making decision about doors. Would definitely recommend Dave and Fortress upvc.”
