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!

KJM Window Install
Customer Service
Quality
Value
The team from KJM called this afternoon, at the agreed time, to install two windows and two secondary glazing units. They were very polite and introduced themselves prior to getting started. Once inside they were very conscious about any mess and cleaned up as they went. The installation went well, unfortunately one of the glass panels cracked while on site - but the team let me know and also called to order a replacement there and then, so that it can be rectified as soon as. Absolute cracking service, after something occurred. It was raining on the day of installation and one of the team took their shoes off when they came inside, very considerate, so that they minimised the mess. They also helped to replace the furniture after the install, which had been moved for access. Windows look fantastic; colour match to the paint work of the building is identical - so overall very happy indeed.

Hello, thank you so much for your 5* review. After you mentioned the cracked glass, the line "Absolute cracking service" made me smile, I'm not sure if that was an intended pun or not? It's good to continue to hear that the fitters are considerate when working in customer's homes. Thank you again for the review, it's very much appreciated. Mark and all the team at KJM

KJM have done a great job at a very reasonable price. The Sales Consultants, Job Coordinator and Fitting Staff were helpful and efficient from start to finish. We would definately go back to them if we need more jobs carrying out in their field.

Thank you for the 5* review, I personally love words like "helpful and efficient" and I am really pleased that you would return to us. We do our best to remain competitive in what are tough times for the industry. As I write this another one of the big nationals failed last week. KJM remain strong and this is another vote for using smaller independent companies. Thank you again from Mark and all the team at KJM

Great work by Josh, Charlie and Ryan in replacing 12 windows over 4 days.Three very polite and engaging young men who worked really well as a team. Josh was very informative and ensured job was done to a high standard. Charlie did a great job of removing kitchen window without disturbing new tiles and tile trim. Any ( minor) issues I identified were immediately dealt with. Very reassuring that Simon, a senior manager, visited both during the job and immediately upon completion to check work. Flawless service from first contact to completion.

Mark who came to value our 5 replacement windows was very informative and professional. Josh who came to install the new windows was great. All the work was completed very fast in 2 days and was very tidy after. Great work from the first to last day. New windows look amazing and we couldn’t be happier. Planning for a new door next year so will use KJM again no doubt. Thank you for all your work.

Thank you for taking the time to review KJM with 5*'s, it is very much appreciated! Living in the same village it was important to us that the new windows fitted in with the character of the property and its surroundings. You chose wisely from our extensive range. Thank you again and when you are ready for your door don’t hesitate to contact me personally. Mark and all the team at KJM
Window Replacement
Customer Service
Quality
Value
KJM replaced all our windows and doors some 27 years ago and they finally required replacing with modern glazing. It was therefore an easy decision to return to KJM as a tried and trusted local business. We initially replaced our aged front door - the change was immediately noticeable. As a result we decided to replace all our old windows. We discussed at length all our options and decided to go with the triple glazing option despite the obvious increase in price as a result. There was a delay in fitting from order but that was down to us being away - fitting could have taken place 4 - 6 weeks from the order placement otherwise. We had initially been told that turnaround would be about 12 weeks but I think that is a worse case scenario as in reality turnaround was much quicker. It took two days to remove and replace all 8 window units. The fitters where on-time both mornings, very professional, tidy and quiet - apart from the noise when actually removing the old units. We were a little concerned that we might have had to redecorate around the window frames as a result of the work but we needn't have worried as no damage was sustained and the units fitted perfectly. They left no mess and even spotted two minor flaws in two of the glass units which were replaced within three weeks. We are happy with the result and have no hesitation in recommending KJM.

Thank you for taking the time to provide such an extensive review on KJM. Having been with the company for 40 years, it is becoming more common to see returning customers who are updating their windows and doors with modern energy efficient glazing. The irony is not lost on me when I consider that I sold you the original windows and the fact your new windows were installed by a team including my son who was not even born on our first visit. KJM’s customer service and attention to detail is why we are still considered by many through recommendation. Thank you again Mark & all team at KJM

Conservatory Roof

KJM came and replaced my conservatory roof in the last week of July. They stated it could take up to 3 days - weather dependent - but took just under two. They worked hard, did an excellent job and left the conservatory absolutely immaculate! There was nothing to do except put the furniture back in. Having used them previously for my windows I was confident they would do a good job and they did.

Thank you for taking the time to provide KJM with what seems a perfect 5* review. It would appear as though the whole team have done what they are asked to do daily for the business, so as the MD I will make the review visible to the entire team and thank them for their continuing efforts.

I recently had a front and back door fitted by KJM and can’t recommend them enough. From the advice given by Mark to the fitting of the doors by Charlie and Josh. The lads were so friendly and worked so well together and you can tell they both have pride in their work. The doors look fab and we are so pleased with them so thank you so much.

Val, thank you so much for taking the time to give KJM a review for your door installation. Josh and Charlie always seem to go the 'extra mile' with customers and seem well liked by many. It does not go unnoticed by me! Thank you again Mark and all the team at KJM.
