    "I had an a bit of an emergency, my bifold doors had badly sagged over time and eventually came off the runner when opening them and I just managed to close them but without locking. Zach came the following day to inspect them and immediately got on with removing all the glass units realigning the hinges and glass within the frame refitted runners, it was a tricky job but end result was superb, better than when they were first installed. He was very professional and was a fair price for the job 👍👍"

    "Zach was quick to respond on WhatsApp and understood the issue right away (broken handle on double glazing porch door). We were able to arrange a visit and get the problem fixed in a day even when needing to source the parts. Communication was great, as was the workmanship and at a reasonable cost. Zach was friendly and professional and exactly the right person for the job."
