Very poor, Had a £3000 front door fitted, 3 months later it started leaking through the doors window panels after a bad storm and water leaked into my hallway due to poor seals, Additionally noticed the door started to fade in colour. The workman also left some long strips and cuttings in my driveway. I phoned up to complain and they gave me a date which was 6 weeks to send someone out. If the 6 weeks wasn't bad enough - Nobody ever turned up - no phone call or nothing. The after sale service is terrible. The fact is prior to this bad service I was about to put in an order for all of my windows to be replaced; that now will be with another company. To summarise the pre sales service was very good the post sale service is atrocious.
