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!

I have found working with all of your staff a fantastic experience and your installation has made a huge difference to the refurbishment of our home. Please extend particular thanks to Anthony who had immense patience helping us to work out what we wanted and needed. When we come to doing a full replacement of the windows in a few years you will definitely be our first point of call.

Secondary glazing on 18th century cottage next to railway line

KJM replaced old secondary glazing in six windows in my old cottage. The work was done quickly and to a high standard. Three of the upstairs windows were done in high spec acoustic glass, and this has definitely helped to deaden the noise from the trains. The work was done in one day, and the windows were left extremely clean and tidy. There was some replastering work needed on the reveals where the old glazing came out, but this was anticipated as we wanted a wider gap between the windows and the secondary glazing to improve acoustic and thermal performance. KJM gave me a good price, were efficient, and I am very pleased with the job.

very pleased with the work the guys from KJM did when fitting my new windows. They arrived nice and early as requested and straight away just got on with the job. They were very friendly and professional, as well as stacking up the removed windows and tidying up as they went along. The windows were fitted a lot quicker than I'd expected and I am very pleased with how they now look both inside and out. A job well done.

Having dealt with KJM previously, we knew that they were reliable. The members of the firm all carried out their role in a professional and efficient manner. The installers got on with the job and left with no damage to window surrounds and very clean. Full satisfaction.

Installation of 2x sets of French doors. Despite issues arising during installation, their response and attention to resolving the issues was maintained throughout. Courteous engineers with an expansive knowledge of the product.

We have just had 6 windows and 2 doors fitted by KJM - from the original request to survey, fitting and finishing, I cannot praise this company highly enough. There were no pressure sales, the survey was exceptionally thorough and the fitting and finishing were second to none. 3 days to fit - in two rooms no need for redecoration and Carl and Alan really cleaned up when they had finished every day (and I am very fussy !). I cannot praise KJM highly enough and would certainly recommend them. An exceptional company, expert fitting and a superior product - thankyou so much.

KJM offer a fantastic high level of service & good value for money. Their team of fitters are second to none. They were extremely hardworking, professional, polite team. They were more than happy to answer any questions I had. I can honestly say that the guys were meticulous with cleaning up at the end of each day. I would strongly recommend KJM and have already recommended them to my neighbors. Keep up the good work KJM.

KJM fitted French Windows for us. They were quick, efficient, good value and professional. The quote was fully detailed and the whole process was a pleasure. I will definitely use them again.
