I'm afraid that Alex DECORs had to return to site as he had over-drilled into the brickwork and the metal gate hinges started to fail after 2 weeks! . I even had to spend another £16 on strong adhesive to complete the repair. Incompetent. And he refused to issue me with an invoice. Please avoid.

It’s unfortunate that I need to give them a poor rating , first instance absolutely great service , however since install the window hasn’t been weighted properly having been told it is . Having to tape it shut says otherwise. Second problem the weight is stuck in the box so now the window doesn’t function. Third issue the window leaks ! It’s hasn’t been sealed properly. Contacted numerous times but had no luck with trying to rectify these issues. No reply after many attempts. Disappointed
