We have had our whole house transformed by KJM with new front door and side panel, 2 pairs of rear french doors, 10 windows all fitted with triple glazed glass panels. To finish we had replacement fascia boards and rain water goods with all materials in matching anthracite. Sales, installation and follow up aftercare have all been exceptional hence a 5 star review is definitely deserved. Less

Had a new front door fitted, and the service from KJM was outstanding from start to finish. Our installer Andy was also incredibly professional and friendly making the actual change over even easier. Cannot recommend enough. Couldn't be happier with the quality of our new front door. Less

Had the best experience today with the KJM installation team. New front and back door, the guys turned up on time with all the equipment and professionally carried out the work. The guys were courteous, very well trained, kept the mess and disruption down to a minimum and very personable.They even helped with readjusting an older patio door that had been installed 20 years ago to try and reduce drafts.I would highly recommend KJM and will not hesitate to use them again. Less

Service engineer Kerry and his apprentice replaced some glass in conservatory, bedroom window and mended patio doors. Prompt, clean, tidy and polite. Thank you! Less

Have used KJM over many years now. Always a fair price, excellent work. On the rare occasion remedial work is needed it is done promptly and professionally even if it years later of the original installation. Less

Amazing service from KJM... two brilliant guys cracked on with the job, very polite, good humour.. can't rate them highly enough. It's a rental house but I will definitely use this company hopefully soon when I buy my own place. Less

Only good things to say about this company. Excellent products, service and aftercare service. Many thanks to Kerry who came out today to replace a pane for us. We’ll definitely be using you guys again and recommending you to everyone. Less

KJM fitted new French windows at our house today. Josh, together with Ryan and Peter, were charming, communicative, respectful and informative, not to mention their excellent handiwork, perfect timing and wonderful finished result. Cannot recommend more highly. Less

Had a whole news set of windows plus a new front door for the house from KJM. The whole way through I found them very professional with a high standard of workmanship. The visit we had for the quote put us at ease as we didn't feel any pressure which is something that automatically puts us off. There were lots of options and we were taken through them all and left with information to think about. Once we had chosen we originally needed some lintels for our windows which were fitted a couple of weeks after we accepted the quote. We then had some wait time while the windows and doors to arrive but now they have been fitted they have transformed the house. The fitters were brilliant. Punctual, polite, friendly and tidy so couldn't have asked for more. They have done a great job and it all looks fantastic. We are really pleased. Less

What a brilliant experience from start to finish. Very honest and great quotation much cheaper than anywhere else to begin with, not trying to rip you off. Door installed today, everyone was friendly, hard working and everything was explained clearly. This is how service should be! Would recommend to anyone in the area. Less

Excellent and speedy job to install a cat flap, very polite tradesman, all interactions with KJM staff to plan the work were friendly and efficient, would recommend to others Less

I recently used KJM to have all the external doors and windows replaced in my home and to have a solid roof installed on an existing conservatory. From start to finish they have been absolutely outstanding. No pushy sales and no complaints when making changes to the styles of doors and windows we wanted and we made lots of changes. Communication was brilliant and I was kept upto date on a regular basis (particularly as I had the works done over December and January and weather was a concern). The teams who undertook the work were excellent and very hard working often working in very cold conditions. Every evening they would clean up and leave everything spotless. Windows were changed without a need to redocorate. Doors and lovely and work faultlessly. New conservatory roof has made such a difference and I now have a room I can use. They even came back and spent several hours cleaning the entire conservatory inside and out. All the staff are outstanding and really friendly and quality of the work cannot be faulted. I couldnt be happier with the results. Less

Had 6 windows and front door replaced extremely pleased with the installation and the fitters that did the job.All the work was completed in two days.The installers were very friendly and polite and on completion they left no mess whatsoever.We are extremely pleased with the finished product.Would highly recommend KJM.

Recently had all of my windows and window boards updated by KJM. Everyone from the sales team, the surveyors and the installation crew were very friendly, knowledgeable and made me feel very comfortable. Special thanks to the installation team, who were probably the friendliest tradesman I’ve ever had doing work at my home (I’ve had many) and who have done such a good job. Would not hesitate to recommend. Less

I have been a customer of KJM for over 30 years and have had windows, doors and a conservatory in that time. The service has always been exemplary as has the quality of the products and pricing has always been more than fair. The latest visit was to replace some glass and the fitter was as always friendly, polite and professional. Also, KJM managed to schedule us in before Xmas - which was very much appreciated. Less

I'm delighted with my beautiful conservatory. It has been perfectly fitted, with great care taken by the friendly fitters the quality is excellent. Friendly service and a fantastic result. Would confidently recommend KJM to anyone. Less

Thanks for a great job on our conservatory conversion, a top job from start to finish, clean, professional and friendly from start to finish. Nothing to much trouble, all the works completed to a high standard, from fitting the roof to plastering and electrics. Advice and guidance from start to finish really good, we recommend highly. Less

I recently had a new composite front door fitted by KJM, and I couldn't be happier with the results! The whole process was smooth and professional from start to finish. The door fits perfectly, enhancing both the security and appearance of my home. The attention to detail throughout was really impressive, and the installers ensured everything was aligned and sealed perfectly. Overall, an excellent experience—I highly recommend their service and the pricing is competitive too. Less

An excellent service from start to finish, from valuable initial advice (especially important on choice of windows as we live in a conservation area) through to the craftsmanship of the fitting and finishing. The actual windows themselves are superb quality and we could feel the difference in our home immediately. The team were superb and couldn't do enough to make sure we were happy. Less

Fantastic service! We've just had a new door and they were friendly and reasonably priced. But most of all they did a fantastic job. Would definitely recommend. Less

I had a window installed recently by KJM which required a RSJ and the two builders who carried out the work were very polite and professional and the finished job was excellent. They also left my area very clean and tidy. The two window fitters were also excellent and did a lovely job, again leaving my home clean and tidy. I have used KJM since 1982 and I would not have my windows replaced by any other company. After sales service is also very good. Less

Excellent service throughout, from initial consultation to institutional. Fitters (Ben & Michael) cleaned as they went, friendly, professional and hardworking, nothing too much trouble. Can not fault thus company, highly recommend. Less

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. Less

After being let down badly whilst with another large company my confidence of trying with another company was shattered.But KJM were amazing from start to the finish of completion of the instalation of my windows I could not have used a better company they were friendly helpful and absolutely nothing was too much trouble, there were no problems at all from start to finish and I will definately be using them again, and will be recommending to everyone I know 100 percent brilliant company and staff .

I was keen to make my Victorian terrace house more energy efficient by replacing all the original single glazed windows with double glazed windows, but I also wanted to preserve the house's character. KJM recommended timber double glazed windows and a double glazed back door from George Barnsdale who manufacture high performance timber windows and doors. KJM did a survey, submitted the order to George Barnsdale, and after a few months' wait for the order to be manufactured, KJM's fitters came to install 6 sash windows, 4 casements and a back door. I was very impressed by the KJM team's helpfulness, knowledge and skill throughout this whole process, from the initial visit from Sales manager Paul Ginger and the survey by Andy, to the installation by Josh and Aidan (with additional help from Jordan). Josh and Aidan were very considerate during the inevitably dusty installation process and they have done a fantastic job. My new windows and door look really beautiful and have been fitted with great skill and very impressive attention to detail. Less

I’ve used KJM many times over the previous 25 years and have always received first class service from the team. Good products and nice people to deal with. Highly recommended. Less

Our experience of KJM Group was first glass at every level. We wanted 2 x large uvpc tripled glazed picture windows as replacements. Their website was very helpful with useful detail. I spoke with a senior manager who promptly visited to carry out the survey and bringing a sample of the proposed window...a 75mm thick 'Residence 7' frame with a triple glazed unit to the 44mm standard....a detailed quote was later received by email the same day. It was pleasure to have fitters Josh and Charley on-site, a cohesive and skilled team with excellent customer facing ability. The installation was smartly finished inside and out, all left superclean and tidy with all debris removed. Our white/pale carpets were unmarked. We much like the flush casement design of 'Residence 7' that has the 75mm frame thickness making it suitable in the replacement context, not requiring any cutting back of plaster/cill board within the reveal. I have no hesitation in recommending the KJM Group. Most pleased. Less

Great team, following a conservatory roof upgrade and new bi-fold doors, we have come to know our team (Ben & Mike) well and who go above the norm to deliver a very professional job. We will be back for more. Less

After collision damaged to our bay window while on holiday, we called KJM for help, they couldn't have been more helpful! First they went round to the property and made sure the property was safe and secure, then Paul made a plan for repairs. Josh and Charlie carefully removed the entire bay and replaced the damaged parts, I can honestly it is as good as new! Absolutely delighted! Recommend KJM Less

Fantastic service all round. So pleased with our new front door and windows. Charlie the fitters attention to detail was 1st class. Would recommend KJM Less
