We would highly recommend KJM to anyone. We had some issues with our window installation but the company went to great lengths to rectify them and gave us a personal service that was very reassuring. We will be using them again!

New Front Door

KJM replaced and fitted a new front door for us. The experience from beginning to end was impressive and we are very happy with the product. The door looks great and the workmanship carried out fitting the door is exceptional. The work was carried out at the agreed price and on an amicably agreed date. All dealings with the KJM staff have been nothing but helpful and we would have no hesitation in recommending them and no doubt will have work done by them in the future.

KJM have fitted all the new doors and windows for our 4 bedroom house and we are absolutely delighted with them. The price was good and work excellent. The porch, doors and bay window were tricky jobs and are now airtight and immaculate. All the windows are beautifully finished off and look lovely. The workers were polite and hardworking, and took care and pride in their work. I couldn't be more pleased and wholeheartedly recommend them.

KJM door fitting

KJM were very professional, from the initial assessment and quote stage, through to delivery and fitting. The fitters, Aiden and Josh, had to take out some brickwork to fit the door and were careful to minimise the mess and clean up afterwards. They also came back a second time to fit the trim, allowing time for an electrician to route some cabling. All in all, a first rate, good value, service from a local company. Job done!

Top-quality professional installation from the team at KJM. We recently had new Bi-fold doors installed during a new kitchen installation and the KJM team worked seamlessly with the other trades to complete the kitchen replacement. We have previously used KJM for the replacement of all of our windows, doors, conservatory, soffits and gutters in previous years and have always found them to be friendly, professional, helpful and reasonable in costs. We would not hesitate to recommend using Paul, Mark and the team at KJM.

Replacement of three old windows with white uPVC to match existing with period monkey tail handles. Efficient customer service. Installation on time finished by experienced staff in a day. Value for money and we are very happy with the result.

I recently had a front and back door fitted by KJM and can’t recommend them enough. From the advice given by Mark to the fitting of the doors by Charlie and Josh. The lads were so friendly and worked so well together and you can tell they both have pride in their work. The doors look fab and we are so pleased with them so thank you so much.

Val, thank you so much for taking the time to give KJM a review for your door installation. Josh and Charlie always seem to go the 'extra mile' with customers and seem well liked by many. It does not go unnoticed by me! Thank you again Mark and all the team at KJM.

Mark who came to value our 5 replacement windows was very informative and professional. Josh who came to install the new windows was great. All the work was completed very fast in 2 days and was very tidy after. Great work from the first to last day. New windows look amazing and we couldn’t be happier. Planning for a new door next year so will use KJM again no doubt. Thank you for all your work.

Thank you for taking the time to review KJM with 5*'s, it is very much appreciated! Living in the same village it was important to us that the new windows fitted in with the character of the property and its surroundings. You chose wisely from our extensive range. Thank you again and when you are ready for your door don’t hesitate to contact me personally. Mark and all the team at KJM
