Just had Jordan and Shae from KJM install our new door, they did a great job and the door looks great. The installation is noticeably more sturdy than our old door and with our 10year guarantee we think we are now sorted!

​10/10 Service from KJM ​Having used KJM a couple of years ago to replace our front and back doors, we had no hesitation in coming back to them for our new windows and French doors—and once again, they delivered a fantastic experience! ​A massive thank you to Charlie and Ryan, our installers—they were so pleasant to have around and did an amazing, professional job. From initial contact with Paul from the sales team, through to the surveyor Andy, installation manager Simon, and Emma who handled the admin, communication and service were top-notch throughout. Thanks again to all involved.

Extremely pleased with the work KJM did replacing all our windows and doors this week. The fitters - Charlie, Peter and Ryan were a lovely bunch who were all polite, friendly and professional. Communication was excellent and they did a great job of tidying up too. Charlie checked we were happy with everything before leaving and nothing was too much trouble for him and the team. Would highly recommend.

So happy with our new windows and doors installed by KJMs extremely professional and crafted engineers; Paul, Lennon & Kerry. From the very start, Charles worked patiently with us ensuring we had the right product for replacing our cottage’s windows and doors. Next Andy ensured everything was made to measure correctly and added the touches that took the look from great to stunning. Engineers Paul & Lennon installed the products with care and clearly they have a high level of craftsmanship.Kerry finished off the stress free process with the final tweaks needed when fitting a high quality product into a 209 year old cottage. And last but not least, Simon’s expert eye ensuring nothing was missed. Thank you to all involved. We are very very pleased with the service and products from KJM and would definitely recommend them.

We had our French doors changed to bifold doors and a window and side door replaced. Very impressed with the quality of the products. The 2 fitters, Lester and Liam were very professional with their work and their attitude. After leaving, other than the lovely doors and windows, you would not have known they had been here. After just a good experience we are now considering more windows.

Very happy with our new uPVC back door. The team was punctual, friendly, efficient, tidy, and asked our opinions when necessary. The new door is a full height triple-glazed door, and so will provide better insulation performance and higher energy efficiency. The locking mechanisms are robust, which is reassuring. It also provides more light in our north-facing kitchen. Overall we are delighted with the door and installation.We will definitely use KJM Group again.
