  • Replace 2 windows with uPVC

    They did a good job and were reasonably priced.

  • New composite door with glass side panels needed

    The crew at Composite Doors themselves are outstanding (Rob/Amber), keeping you informed of progress/delays, responding to communication promptly, etc. The door needed minor adjustment after a few months and this was also rectified. The only issue is they sub contract out the actual fitting and unfortunately we were sent Steve from A1 fitters who turned out to be a bit rogue so may be just ask for an alternate fitter and all should be good. Positive for composite doors staff, negative for their fitter so neutral overall. I'd use Composite Doors again just specifically requesting a different fitter.

  • Replace two double glazing units

    great job replacing windows, good communication throughout, even in the covid pandemic!!
