KJM Window Install
Customer Service
Quality

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

This is the second time using KJM - they previously replaced our front door - this time they replaced three windows at the back of our house. The whole process from quotation, survey and fitting was brilliant. Just a really nice company to deal with; the quality of all the items we have had fitted are excellent. A big shout out to the fitters, Josh, Charlie and Ryan - what a dream team - they just couldn't have been more helpful and polite and left our house clean and tidy; they really knew how to do their job properly. 100% confidence in this company.

KJM have done a good job on our back door. They helped us choose which one would be suitable and then fitted it. Andy did a really neat job and it looks great. We would not hesitate to ask KJM to do further word on our house if required.

The workmen did an excellent job. I am delighted with the triple glazed windows and front door in my bungalow. The men were unfailingly pleasant and polite. As well as being extremely efficient with the work, they put cloths down straightaway and they vacuumed at the end of each day, leaving everything clean and tidy. They arrived at the time they said they would each day and could not have been more helpful. I was very grateful to have the window and door locks explained in detail and demonstrated. I live on my own as my husband died last September so it was good to have practical things explained. I was told exactly how much it would cost and paid in three stages - a deposit when I booked them, a middle amount when the work started and a final invoice.

Good morning from all at KJM. Thank you for taking the time to give KJM a comprehensive 5* review. To see the words "unfailingly pleasant and polite" makes me so proud. I have just phoned the fitting team to thank them for their continued efforts at making KJM's customer service what it is today. We are all really sorry to hear about your loss and if we can help anyway in the future with other projects then dont hesitate to ask. We have an extensive network of suppliers and contacts who I would happily recommend. Mark and all the team at KJM.
New front door and side windows

Another professional job from KJM. We have just had a new Solidor front door fitted to our 1930's house. Firstly they gave us helpful advice on choosing the right door for our property and after a few visits to their showroom we made our decision on the door, glass and fixtures. The survey revealed the need for a steel lintel above the door and the subsequent building works were carried out beforehand causing minimum disruption and in keeping with the property. A very professional installation of the door and two side windows was carried out by the two fitters who kept everything very clean and tidy whilst they worked. This was the third time we have used KJM having previously had two bay windows and several other windows replaced by their team over the past four years. We are very pleased with all the works carried out by KJM, everyone in their team is helpful, polite and friendly and we would not hesitate to recommend this company.

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.

We are delighted with our new solid roof, Ben and Mike, the fitters, were friendly, professional and nothing was to much trouble. Any slight problems incurred were highlighted, discussed and completed to a high degree. They worked cleanly and cleared up as they went to keep the site as clean as possible. Special mention for the electrian, Dominic and the plastering team that sorted the inside of the conversion, all works were completed cleanly and to the highest standards. We were also consulted all through the build by Brian, can't recommend KJM highly enough, thank you for a great job.

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.

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.

This was the first time we had bought windows and door for a property, so went in with only a basic idea what we wanted and needed. We had a few quotes from a few different companies, the first thing that stood out about KJM was the Sales Consultant Luke F. Luke appears to genuinely want to get the best deal for the homeowner and KJM, he explained the range of products and the pro’s and con’s of each and gave his personal opinion when I asked him to. He didn’t try to push a sale at any point and went away to work out a proper quote for the work we requested. The 2 gentlemen turned up bang on time on the day of install, and did the work to a high standard. They were careful around the house to make sure they didn’t make any mess or cause any damage. The install took a few hours and a full demonstration was given at the end. We are totally satisfied with the work and price we paid. I wouldn’t hesitate to recommend KJM to friends and family!
