I have had a number of disappointments recently from suppliers but KJM was a pleasant surprise. From the point of quoting it has been seamless. I had good advice from Andy when doing the survey. Charlie and Ryan turned up to fit the door on time, did a brilliant job, tidied up after themselves and had fantastic communication skills throughout. They were down to earth and are a credit to KJM. Very happy with the finishand would not hesitate to recommend.

We were very pleased with KJM and Kerry in particular for the work that was carried out last week. He did several repairs to locks and hinge's on both doors and windows, he also replaced handles. Our back door was completely replaced. He was very polite and a real gentleman. I would not hesitate to recommend KJM.

From the moment we walked into the KJM office, our experience was first class. Paul Ginger guided us through choosing our new door, Tony Walker carried out a thorough and professional survey, and Lester and Zach completed the installation to an exceptionally high standard.The whole process was smooth from start to finish, with excellent communication and customer service at the heart of everything they do. It’s refreshing to deal with a company that genuinely cares about its customers and delivers exactly what it promises.A huge thank you to everyone involved. We wouldn’t hesitate to recommend KJM to anyone looking for new windows or doors. Well done! 👏

I would like to say a huge thank you to Ryan, who came out and repaired our window very last minute. Very kind and chatty young lad.

Great company and staff , Jordan and shae are credit to your companyPerfect job completed ( apart from a small window lol)

Arrived early which was great news. We had ordered replacement glass with integrated blinds for our existing bifold doors which we had previously purchased from KJM. Both engineers introduced themselves, were very friendly and did a great job. After installing they showed us how to operate the blinds which was really helpful. Everything was left spotless. Can’t say anything negative. It’s not the first time we’ve used your company and it won’t be the last.

From start to finish, the team delivered outstanding workmanship and professionalism. The attention to detail on our windows and door replacement was exceptional — perfect sealing and everything operated smoothly on first use. They protected floors and furniture, worked neatly, and left the areas immaculate.What really stood out was how considerate they were when a neighbour raised a concern. They handled it calmly and respectfully and genuinely felt they cared.They also went the extra mile by fitting a cat flap in our new door which was really convenient and kind.Professional, punctual, tidy, and genuinely thoughtful — I’d recommend them without hesitation.Thanks everyone so much!

We have recently had 24 new Graf welded Deceuninck 2800 flush casements windows in agate grey, installed in our Andover Workshop and showroom. The transformation is amazing.The process from initial quote, to finalising details, site measure, manufacture to installation went incredibly smoothly without delay.The installation team worked through the extra hot weather without complaint and did a stunning job.I know window companies can get a bad press particularly when it comes to installation. I would not hesitate to recommend The KJM group to my clients.Andrew HallManaging DirectorWoodstock Furniture

Amazing service - could not lock door due to heat from heatwave and KJM arrived within about 10 minutes of our call! All windows and doors in our house are from KJM. This is why!

5/5 Stars – A Life-Changing Transformation!​If you want exceptionally high standards and a trustworthy team, look no further than KJM. They recently built us a conservatory, and it is incredible. We used to have a rubbish garden room that leaked, was freezing, and looked horrible. Thanks to KJM’s brilliant design, we now have a stunning family room that is completely life-changing for us.​The entire process was faultless from the initial sales visit to the final sign-off with Brian, who was a fantastic coordinator. Builders Michael and Ben were absolutely brilliant too, doing a fantastic, highly skilled job putting the frame up.​But a massive shout-out goes to our brickies, Ant and Colin, who were the absolute stars of the show. I cannot praise them enough; they are the most friendly, kind, and hardworking people you could ever meet. Most contractors are incredibly disruptive, blasting radios and ignoring your routine. Not these guys. They were so deeply mindful of our working commitments and incredibly respectful of our neighbours. They just put their heads down and worked tirelessly, showing a rare level of pride in their craft. Having them on-site was a total pleasure.​If I had to sum up KJM, they are: faultless, high-quality, professional, easy to contact, reliable, hard-working, and entirely trustworthy. If you want an exceptional design, a stress-free build, and a top-tier team, go nowhere else. Thank you, KJM!

Kerry came and repaired the catch on our window quickly and efficiently

2026-06-22T11:47:32.040Z

Having previously had a new front door installed by KJM, and having been thoroughly impressed with the service I received, I immediately thought of them when the window of my en-suite failed to lock. I was aware that KJM had not fitted this window but thought I would try. I was not disappointed.The engineer arrived to see it they could help, the company sent a quote l, which I accepted. The part was ordered and when it arrived, Kerry came to fit it.Great communication throughout and a service second to none.I would recommend KJM without any hesitation.

2026-06-16T20:14:56.882Z

We’ve just replaced our old bay windows that KJM fitted over 35years ago and installed windows with acoustic glass to reduce street noise and upgrade to a more modern style .The noise reduction is amazing my decibel meter registers the road traffic as a “soft whisper “The quality and finish of the new windows are exceptional. Highly recommended

2026-06-16T09:52:57.296Z

Had broken my window cutting the grass and called KJM straight away. Instead of waiting until the following day for someone to attend, the director Mark was on my doorstep within 30 minutes to measure up and quote to replace the glass.The quote was done within the hour and paid for, after a short wait of a few days for the glass to be manufactured and delivered, Kerry was out and fitted it. It took less than an hour to fit and he gave me some good advice on cleaning the frames in the aftermath of having to tape the old glass up.Really appreciate the quick turnaround and seamless process in arranging measuring, payment and fitting. Would recommend to anyone who does the same as I.

2026-06-15T10:09:21.350Z

KJM has been coming to our site for many years. During that time they have installed new composite doors, guttering and facias. They have also supplied and built a large conservatory.The engineer who covers our area is always polite and professional and is trusted to work with older people.I wouldn’t use anyone else.

2026-06-12T17:40:39.861Z

Very helpful, from understanding our needs and ordering the correct glass, to arranging a convenient time for the engineer to visit, and the Engineer himself - friendly, efficient and tidy. A great job all round.

2026-06-11T13:30:05.518Z

I couldn’t be happier with my new front door and bifoldCharlie and Ryan who fitted it couldn’t be more helpful and considerateShowed me how everything worked, turned up on time and communicated well on all frontsThey even helped me fit my new door bell while they were here 🥰I will definitely be getting the rest of my windows and doors done as the product quality is brilliant and the customer service couldn’t be better

2026-06-09T16:03:09.847Z

Had windows and a lift and slide back door fitted in South Wonston. The guys (Charlie, Ryan, Mike and Will) were brilliant. Very courteous, hard working and a good laugh. Really high standards throughout. They planned for 4 days but finished in 2, despite having to negotiate the pouring rain on day 1.The whole experience with KJM, from quote (Charlie and Paul) to survey (Andy) to fitting has been very positive. Would definitely recommend this company. Thank you guys!

2026-06-08T10:47:44.989Z

I recently had a new uPVC front door installed by KJM and I couldn't be happier with the entire experience. From the very beginning, the sales and survey team were professional, knowledgeable, and gave me great advice.The installation team, arrived promptly, were incredibly polite, and respected my home throughout the process.5 star you need look no further than KJM .

2026-06-07T14:50:55.879Z

Our third time using KJM and would still highly recommend! The whole team from sales to survey to install to payment are very polite and a pleasure to deal with. The install guys were especially good, turned up on time, explained everything that was happening each day, asked questions rather than making assumptions, worked very hard and cleaned up after themselves. This was phase 1 on our current house and we’ll be back for phase 2 as soon as we’re ready!

2026-06-04T18:37:01.235Z

So glad we chose KJM. Everything went smoothly from start to finish. The installation team of Zack and Lester were very professional and very polite.

2026-05-27T14:46:03.893Z

Great company to deal with, competitive prices without pushy salesman. Zach and Lennon were very efficient and tidy. They highlighted some issues I wouldn’t have noticed and will be coming back to remedy them. Can’t fault them.

2026-05-26T14:06:00.730Z

Excellent and highly professional throughout work. Would highly recommend. An illustration of their professionalism was that Ben the fitter popped round on Bank Holiday Monday to check that the new front door was operating as it should in the extreme heat.

Since we had an aggressive double salesman who in the end we had to ask to leave after midnight some years ago we have been dreading the time when we would have to replace our doors and windows.Our experience with KJM could not be more different, Charles from their sales team visited us at home, listened to what we wanted, outlined suitable products and provided helpful advice without pushing anything on us. He later gave us what we thought was a very competitive price. All without any pressure or commitment on our part.Everything went as planned and Charlie, Ryan and Peter, from their installation team turned on the agreed date and completed the work to an extremely high standard, showing care, consideration and a remarkable attention to detail in a couple of days.Simon from quality control made several visits to make sure we were happy and that things were going as planned.In summary we would have no hesitation in recommending KJM to others, commend their management for their straightforward approach to business and all the staff, included those not mentioned above, that we came into contact with for their polite, helpful and can do approach to our project.

2026-05-21T10:27:13.487Z

A huge thank you to KJM for delivering an amazing extension for our home.From start to finish, the workmanship and attention to detail were fantastic. Brian and the entire installation team were professional throughout, always keeping everything clean and tidy as the project progressed. Even our neighbours commented on how respectful and hardworking the team were.Thank you all for making the whole project feel seamless and stress-free. We are absolutely delighted with the finished result and would 100% recommend KJM to anyone considering an extension or home improvement project.

2026-05-18T11:35:23.851Z

We had a wonderful and stress free experience having all our windows replaced, from the initial meeting & quote to installation.Everything was delivered as promised and on time.There were very various options available to us, but at no time was there any hard selling, just genuine recommendations on what would be best for our needs.Installation was completed in 2 days and the fitters were polite, courteous and left the house clean and tidy after they had finished.We can highly recommend KJM for their customer service, pricing and delivering what was expected without any fuss hassle or delay.Thanks to all at KJM

2026-05-15T11:46:05.229Z

Great experience from start to finish.The guys turn up on time, friendly and helpful, get the job done with no fuss and clean up after. Great service and great team. Highly recommend KJM and the team that fitted the windows.

2026-05-12T17:00:54.640Z

I have been a customer of KJM for a number of years and the service has always been good. In May I had a new door installed by Zack, Adam and Lennon. It get did a professional job and took away all the rubbish. I have no hesitation in recommending KJM. DB

2026-05-11T14:52:24.031Z

We have used KJM for all of our windows and front door, we are very happy customers. It’s a bonus being able to go to a showroom and see the products. The knowledgeable sales team (Paul W and Andy), coordination team (Emma) and installers (Zach, Adam and others) are a pleasure to deal with. Cannot recommend KJM highly enough!

2026-05-11T07:01:55.253Z

From the initial enquiry, through design, installation and completion the service, communications and quality was of the very highest standard.
