KJM have done a good job on our back door. They helped us choose which one would be suitable and then fitted it. Andy did a really neat job and it looks great. We would not hesitate to ask KJM to do further word on our house if required.

To spread the load, KJM have installed windows twice and we have just booked the last phase. They have been very professional each time, from the initial measuring up, then the survey and finally the fitting. I cannot recommend them highly enough. The quality of the finished product has been very impressive, a real upgrade for us.

Excellent Replacement Windows and Affordable

We found KJM via Google whilst searching for 4 replacement windows with integral blinds. We visited their showroom and viewed some samples at the same time they give us a quote for the work. We set a date, for a visit, for them to measure up (check my measurements). Thankfully the original figure didn't change for the worse and we booked in the job. On the fitting day the fitters turned up early and had the job completed by around 3.30pm. I must admit from start to finish their service was excellent. I felt that they knew what they were doing and didn't hide anything from me. The fitters workmanship was super. They were friendly, helpful and and discussed the work as it progressed. My house is very old and getting the windows square didn't seem to cause an issue. All in all my wife and I are very pleased with the result and we have had lots of admiring comments from my neighbours. Would I recommend KJM to any prospective customer - yes I would in a flash.

This is the second time using KJM - they previously replaced our front door - this time they replaced three windows at the back of our house. The whole process from quotation, survey and fitting was brilliant. Just a really nice company to deal with; the quality of all the items we have had fitted are excellent. A big shout out to the fitters, Josh, Charlie and Ryan - what a dream team - they just couldn't have been more helpful and polite and left our house clean and tidy; they really knew how to do their job properly. 100% confidence in this company.

We are delighted by the new windows: the team installing them was very professional and took a real pride in their work. There was one slight moment with a piece of broken glass but it is being sorted and was well managed.

I had 3 new windows fitted last week. Lester & Liam worked very hard & efficiently. I am extremely pleased with the windows & their fitting. It was also reassuring to have Simon check on & discuss their progress with me every day.

Many thanks for making such an excellent job of replacing the roof of our existing conservatory. After the initial quote, we were able to go with a representative to see a roof replacement in our area and we were very impressed with the work. We decided to use KJM for our roof. From start to finish they took over the project. Drawings and planning were all done on our behalf. All the various workmen liaised together very well and explained what they were doing at all stages. The existing floor was carefully covered, and the lights were fitted into the ceiling. All the site was cleared after the work and left neat and tidy. Plastering was included so we only needed to find a decorator. We are delighted with all the work and it has changed from a conservatory to a room which is part of the house. We would definitely recommend KJM if you are considering improvements of this type.

Couldn't be more pleased with this - 2 bays, 5 windows and French doors installed with great care and precision, and at a very fair price. All the team at KJM have been brilliant: informative, meticulous, careful, skilful, cheerful and friendly. It was a pleasure to have you around. Thanks to Paul for initial advice, Andy for surveying, Josh and Aiden for all your hard work and Emma for coordinating. Sorry we couldn't give you better weather! Next in line is the new front door!
