  Professional and prompt

  Gary was very professional. Popped in to have a look at the job and quickly gave me a quote. The unit was replaced and he also fixed the window locks systems through out the flat. Highly recommend.

  supply and fit 2 windows

  getting shot of two old, terrible windows in older building - removal of seriously rotten old debris and instal of modern high quality units. superb facings created indoors and out, everything left tidy, and a complete transformation. What a great job. really excellent people, very highly recommended.

  Tilt and turn window repair

  Great experience with the company. Gary did not charge anything for the initial call out and came round within a day or so after I had got in touch regarding the work. He came round and recognised the problem I had and indicated it was likely another repair that hadn't quite been done correctly to the window before I had moved in. He then completes the work promptly and at a very reasonable price. Will definitely be in touch again for any future work.

  Bathroom handle and lock mechanism fixed!

  Needed my bathroom handle and locking mechanism replaced and Gary sorted this in less than 24 hours from my call. Turned up when he agreed to, completed the job quickly and efficiently and left me very happy with the outcome. Will definitely use again if required and needing something fixed quickly.
