Thank you KJM. We have just had a Compdoor fitted by the excellent team of Charlie and Josh. The product is top quality as expected from KJM and so much better than the ‘new build’ front door fitted by the developer. It looks good too. Charlie and Josh worked in the pouring rain but with great humour and so helpful with explanations. A great team and a credit to 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.

We had three doors replaced with comp doors. The customer service from start to finish has been exceptional. Honesty from the sales and surveying team, very clean and tidy fitting of the doors by 3 very happy chaps! They made sure we were 100% happy with everything before they left. It has been a pleasure dealing with KJM and we would highly recommend them. Costs were good and there were no hidden surprises.

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.

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.

To spread the load, KJM have installed windows twice and we have just booked the last phase. They have been very professional each time, from the initial measuring up, then the survey and finally the fitting. I cannot recommend them highly enough. The quality of the finished product has been very impressive, a real upgrade for us.

Excellent Replacement Windows and Affordable

We found KJM via Google whilst searching for 4 replacement windows with integral blinds. We visited their showroom and viewed some samples at the same time they give us a quote for the work. We set a date, for a visit, for them to measure up (check my measurements). Thankfully the original figure didn't change for the worse and we booked in the job. On the fitting day the fitters turned up early and had the job completed by around 3.30pm. I must admit from start to finish their service was excellent. I felt that they knew what they were doing and didn't hide anything from me. The fitters workmanship was super. They were friendly, helpful and and discussed the work as it progressed. My house is very old and getting the windows square didn't seem to cause an issue. All in all my wife and I are very pleased with the result and we have had lots of admiring comments from my neighbours. Would I recommend KJM to any prospective customer - yes I would in a flash.

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.
