We couldn't be happier with our new…

We couldn't be happier with our new windows and doors from KJM Windows & Doors!

Over the summer, we had all of our windows and doors replaced with uPVC windows and beautiful agate grey composite doors. We also had French doors fitted where there was previously a window, which has completely transformed the space and made such a difference to our home.

It was a big job, and we got quotes from several other companies before choosing KJM. Their price was very reasonable, and looking back, we'd choose them again in a heartbeat.

From start to finish, the service was outstanding. Charles was brilliant during the quoting stage—knowledgeable, helpful, and never pushy. The office team kept everything running smoothly and were always friendly and responsive.

A special thank you to Zac and Lester, who carried out the installation. They were incredibly polite, friendly, hardworking, and took real pride in their work. Their attention to detail was second to none, and they left everything clean and tidy each day.

Finally, Simon's quality control visit really showed KJM's commitment to getting everything perfect.

The whole team has been fantastic, and the finished result has exceeded our expectations. The quality of the windows and doors is excellent, and we genuinely couldn't be happier. We would thoroughly recommend KJM Windows & Doors to anyone looking for high-quality products, reasonable prices, and exceptional customer service.

I will be sure to pass your kind words on to Charles. Providing knowledgeable, helpful, and completely pressure-free advice is exactly the ethical approach we build our business on. Emma and the rest of the office team will also be delighted to know that you felt well looked after behind the scenes.

Excellent service, a clean and welcoming atmosphere, and very friendly staff. Megan was my hairdresser and was fantastic—professional, helpful, and attentive. Highly recommended!

Hi there,

Thank you so much for the fabulous 5* review. However, I think there might be a slight case of mistaken identity...

We are KJM Group, a window, door, and conservatory installation company based in Andover. While our installation lads are incredibly precise with a tape measure and a sealant gun, I really wouldn't recommend letting them anywhere near your hair with their PVC saws! We also definitely don't have a Megan on the team, though after reading this, we might have to look into hiring one.

It looks like you meant to leave this lovely feedback for KJM Salons over in Fleet! It just goes to show that any business with "KJM" in the name naturally provides exceptional service and a brilliant atmosphere. 😉

We are thrilled that Megan gave you such a fantastic haircut. We will leave the styling to her, but if you ever need a beautiful new front door to match your fabulous new look, you know exactly where to find us!

Best wishes,

Mark and all the (non-hairdressing) team at KJM

Really professional installation for French doors

KJM installed two sets of double glazed French doors for us in August 2026.

Lester and Shae were superb. They were punctual, polite and obviously professional. They worked in full sun on the hottest day this year without complaint or pause. They explained what they were doing and sought confirmation (such as where we would like the hook backs) as required. But basically, they just got on with the minimum of fuss. You can be justly proud of them.

The French doors make a massive difference so thanks to all those involved from initial survey, through measuring up, chasing the supplier, etc. A great team.

Hi there,

Thank you for the fantastic 5* Trustpilot review. We are absolutely delighted to hear that your two new sets of double-glazed French doors are already making a massive difference to your home.

I will be sure to pass your wonderful feedback directly to Lester and Shae. Working through the hottest day of the year in full sun is certainly no easy feat, so their dedication to getting the job done without a single complaint is a real testament to their work ethic! They will be absolutely thrilled to know how much you appreciated their punctuality, their polite approach, and their communication regarding the cabin hooks. I completely agree with you—we are incredibly proud to have them on the team.

It is also brilliant to hear that you felt well looked after by everyone else behind the scenes. From the initial survey and measuring up, right through to coordinating with the suppliers, we always strive to make the entire process as seamless and stress-free as possible.

Thank you again for choosing KJM for your installation. If you ever need anything else in the future, please do not hesitate to get in touch.

The whole team made my experience seamless.. from the first engagement with Charles, who never chased up the quotes, just always very helpful and he was right !. I was going for the chartwell green, went into showroom and chose agate gray and I love the colour.
Andy the surveyor advised on style Graf welded Deceuninck 2800 flush casements and again, perfect.
Finally Paul and Lennon installing the windows, professional and very efficient.
I cannot recommend KJM enough and I’ve just ordered some more windows.
Finally it is evident all the guys enjoy what they do and working at KJM, which is really nice to see and hear.

Hi Kirstene,

Thank you so much for taking the time to share your wonderful 5* Trustpilot review. We really appreciate you leaving such glowing feedback across multiple platforms.

I am absolutely delighted that taking a trip into the showroom helped you decide on the Agate Grey instead of the Chartwell Green. It really is a stunning colour, and it pairs perfectly with the Graf welded Deceuninck 2800 flush casements that Andy recommended for you!

I will be sure to pass your kind words on to Charles; providing a helpful, no-pressure experience is exactly the approach we strive for. I am also thrilled that Andy’s technical advice hit the mark, and I will definitely share your brilliant feedback with Paul and Lennon. They are a fantastic duo who take immense pride in working efficiently, and they will be delighted to know you enjoyed having them on-site.

As I mentioned before, your comments about the team genuinely loving their jobs and working at KJM mean the absolute world to us. Cultivating that kind of positive environment is incredibly important to us, and it is wonderful to hear that it shines through in our work.

Thank you again for your high recommendation and for trusting us with your next set of windows. We are already looking forward to getting those installed for you!

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.

Hi Andrew,

Thank you for the fantastic 5* Trustpilot review!

It is absolutely brilliant to hear that the new Deceuninck 2800 flush casement windows have so completely transformed your Andover workshop and showroom. Agate grey is a stunning choice, and the Graf welding really does provide that seamless, premium finish.

I will be sure to pass your high praise on to the installation team. Powering through the extra hot weather to deliver a stunning job is a real testament to their hard work and dedication, and they will be thrilled to read your comments.

We are incredibly proud of our straightforward approach from the initial quote right through to manufacturing and installation. We know our industry can sometimes carry a poor reputation, so receiving such a strong recommendation from a fellow Managing Director to your own clients is one of the highest compliments we could possibly ask for.

Thank you again for choosing us for such a significant project. If you ever need anything else in the future, please do not hesitate to get in touch.

Had bifolds fitted along with other windows. Didn't fit properly from the start as I was unable to fully turn the handle from day one. Couple of years later was getting worse and looks like frame has bent. Was put down to subsidence of which there is no evidence. Ultimately tried to give the stereotypical double glazing salesman retort of 'you can see from the patio' (which obviously has a gradient for run off) , you can tell from eye etc. House is on existing extension site and is on chalk. Washed hands of it and blamed builders for measurements and builders blame them.

Mark Pearce Managing Director replied in June 2024 with this email to Robert Hall.

Good evening Robert

I have all the complaint emails you made about the doors initially and sadly there is no mention of the doors not operating properly. You tried to reduce the balance owed by making various allegations against KJM, most of which in my opinion lay at your builders failure to put the bottom course at the correct level.

I have not contacted the manufacturers because there currently is no reason to do so. The surveyor said what I have already told you, both doors are not working because both thresholds are falling away towards the corner post. If the thresholds are not level then the doors will not function correctly. As many of my previous emails state to you, at your request the doors were set at the lowest level possible so on the brick/block course beneath. The doors were not packed at all on the threshold so are reliant on what they are sat on. The fact that both doors have the same problem points to the stability of the underside of the doors.

Although I cannot be certain, I am 99% confident that the brickwork beneath is the cause. So if we remove the doors and this is the case are you going to foot the bill for our time? Our warranty is based on faulty products, not what they are sat on. With the doors removed if there is a big enough gap at the top we could pack underneath to level them, but if this continues to fall away the problem will return.

Just like you I would like a resolution but not at my expense if we are not the cause of the fault.

We then offered the following:-

Hi Robert

That is the problem, the doors did work, so something has shifted under the doors. So I would refer you to my original email sent a few weeks ago

“Good morning.

I’ve been made aware that the bifold doors are not operating properly because the frame threshold on the doors has dropped. I understand a solution has been offered to remove the doors and see if we can level them up again.

The purpose of the email is to clarify that if it is found that this is due to the brickwork underneath the doors (I believe we sat the doors direct to the brickwork to get the threshold level as low as we could) then this will of course be chargeable to you.

Please can you confirm that you are happy to proceed on this basis”

An email from Robert Hall stated the following (contrary to the review)

“Thanks for the email and I think you're right about being on the brickwork without shims. What's the proposal to take out and re-fit, how do you think that might work?

I also agree that the door support is off level, but it could have been off level at the start. What makes me think it may have been off before is that there is no evidence elsewhere of movement. Even the slightest movement in the front part of the house (the original part that can't have moved) has led to some cracks.”

I had KJM replace my French doors from plastic to aluminium. Wow what a difference. The team who did the fit Zack and Lester was amazing, as was all the staff I dealt with. I have a small problem with one of the doors and KJM are happy to get it sorted for me. So highly recommended.

Excellent products and service. 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

Amazing service from quote to install

Amazing service from quote to install. The fitting team were very friendly and professional. Did a great job at fitting the French doors and the finish to the trim is amazing. Within an hour of install a post installation visit was made to check everything is good and I’m happy with the job. Not sure I have ever received such good service. This is my second experience with KJM after a conservatory build a few years ago. Again not disappointed!! Thank you all at KJM will be returning in the further I’m sure.

Window Repair

We had a window that was supplied 10 years ago that would not close. I called KJM and they could not have been more helpful, bearing in mind this was a very small job and probably a pain. They visited us, understood what needed to be done and came back to complete the repair, at a very low price as well. A very pleased and impressed customer.

New replacement conservatory

We were recommended this company by friends who had a new conservatory from them. Paul Ginger came out at the agreed time to go through our requirements and came up with good suggestions to which we went ahead with. An agreed start date was given. The workmen came in and dismantled the old conservatory very quickly and cleanly, the new frame work went up just as quick. Scaffolding was erected on the date expected, other trades arrived when they should have especially Neil the sparky, (very professional). The whole job was finished in the specified time although a few snagging jobs did take longer to rectify than expected. All in all we would recommend this company and are very pleased with the finished project.
