    KJM are a great company to deal with. There is no selling pressure and they go out of their way to do the best job possible. They listen to your concerns and requests and are always happy to return should there be any problems after installation. I can definitly recommend them to any potential customer.

  • New Front Door

    10Verified Review

    We have used KJM for all of our replacement windows, doors and conservatory over the years, and have always been satisfied with their workmanship. Our new front door has been no exception. Turned up on time, polite, friendly, did a great job and tidied up once finished. Can't recommend enough!

    The team, notably Simon, were utterly professional keeping us informed of all the progress with regular updates (phone calls etc) and photos as we had the work undertaken whilst abroad which is never easy but with his proactiveness it has been stress free. A fantastic company and I cannot recommend highly enough.

  • Replacement Double glazing - 11 windows

    10Verified Review

    The work finished ahead of schedule even with the adverse weather and issues with the old windows. The staff were very polite and professional in all respects and cleaned and tidied up completely each day before leaving. We are extremely satisfied with all the work which was fully inspected by a manager upon completion to ensure there were no snags. Communication before, during and after the work was excellent.
