We had previously used KJM as part of a build project to fit bi-fold doors and were very pleased with the outcome. We dropped into their showroom to discuss replacing the other 12 windows as they were over 25 years old, an advisor came out to see us firstly asking what type/look of windows we wanted and then talked us through our options including the standard of frames and glass available and produced a detailed costing. At this point I should mention there is no messing around with KJM on here’s a cost! Let’s take this off for this and that and arriving at a final price, (as with so many competitors) you are given the cost at the beginning…no messing around! Arranging fitting was so easy as was changing it and was carried out professionally and with great care. The fitters explained what they were going to do and got on with the job efficiently and with a friendly manner. Job took just under three days and everything was left perfectly tidy each day. At the end of the fit we were walked through the operation of the windows, ongoing care and service by KJM and to check we were satisfied with the finishing of the fitting. Very good local company and professional service. Great product and fantastic looking new windows.

Thank you for taking the time to review KJM. I am pleased to hear that all parts of our service met expectations. Employing our own staff means that sales-commissions are not a part of 'our sales patter' hence the good old fashioned honest pricing policy. That way will always be our way of doing business! Thank you again!
KJM secondary glaze project

Second time I've installed a secondary glaze and first time with KJM. Big project and very professional/pleasant. I'm very pleased with the quality of product and installation; hardly tell it's there after a week. All about heat retention, as a priority, not sound, and KJM worked with me on this. Both the install teams were v knowledgeable, efficient and tidy. Only downside is the lead times as v busy

Thank you for taking the time to review KJM, we really do appreciate it. I am pleased to hear that we treated you well and can only apologise about the length you had to wait. The pandemic made us very busy with a very slow supply chain. Things have now improved and lead times are much lower. Thank you again
Fantastic work - efficient and tidy

KJM came to replace 6 windows including a bay, front door and French doors where a window was prior to the job. They deserve huge praise for their quality of work, which is outstanding. They were more than happy to make small amendments where they could, even asked us how we'd like certain things I wouldn't have even thought of. They walked us through every step of the process, the what's and why's and made sure we were 100% happy with the result. They were extremely accommodating with some of my OCD wishes for continuity and aesthetics. They were true to their word and arrived when they said they would; if not a little earlier. They also cleared up all mess they made, to the point of mopping the kitchen floor! After all is said and done, you wouldn't have even known they were here. Although no work is ever perfect, they came round and took the very few concerns we had and ensured a resolution was put in place - I cannot possibly fault any part of the process from beginning to end. I will be using KJMs services again in the near future for further work.

Would Highly Recommend KJM Windows......

We recently had our front windows replaced and a new front door fitted by KJM. Firstly, I would like to say what a lovely and honest guy Mark the owner is, he came and measured up and quoted us for the work originally and was very helpful and even adjusted our doors we weren't having changed and advised us on what replacement handle we needed to buy, at no cost to ourselves, what a star! I will say our quote was very competitive and the quality of our windows and door are amazing and we are so pleased. We had a problem with part of our door fitting due to a manufacturing fault, Mark came round personally and we had discussions and he went away and re-ordered the part in question and recitfied the situation. I am going to mark the company down by a point on Customer Service, as I feel they could have been a bit more proactive in updating us to what was happening between the point of ordering and fitting the windows and I had to chase them. I am fully aware of the current econmic situation and what businesses are up against but because of this, there is more than likely to be more waiting time and delays for the customer, so I then think it is even more imperative the customer is fully informed and updated at all times. This is my only slight niggle, otherwise it would have been full marks and it is definately full marks for Mark. All in all, I would not hesitate to recommend KJM, they are very honest and trustworthy and you will not be disappointed!Thank you Mark & Team

We had a problem with a PVC replacement door not locking. We asked locally and got recommendations for KJM. Called late afternoon to speak with the owner and received a promise for a visit the next morning. Mark turned up at 08:00, and by 08.10 had the door working again. Didn't stop there though. Spent the next 15 minutes adjusting everything and anything until the door fitted and worked better than at any time since it was fitted. After all that, refused to take a payment since he'd been at another appointment a short drive away. I can't recommend this group and it's boss highly enough.

Really impressed with KJM - a brilliant experience from start to finish. From the initial visit and measurements to the installation work itself, the experience couldn’t have been better. The installation work was completed quickly and conscientiously, and the quality finish is superb. Very satisfied customers.

Work done to a very high quality. Cleaned after, perfect. Door was a better than thought as heavy but so light on hinges. made so much difference to front of house... bit of class... Windows in house are 25 years plus from KJM so new door had to come from them. So pleased... if they see this thank you...

Will have no hesitation using them again.

KJM have fitted all the new doors and windows for our 4 bedroom house and we are absolutely delighted with them. The price was good and work excellent. The porch, doors and bay window were tricky jobs and are now airtight and immaculate. All the windows are beautifully finished off and look lovely. The workers were polite and hardworking, and took care and pride in their work. I couldn't be more pleased and wholeheartedly recommend them.

The door fitting was very efficient, tidy and really good standard. The fitter was very friendly and prompt, ensuring everything was in place and working before leaving. Initial quote process was thorough so no need for any follow up visit. Could have done with an earlier update between quote completion and fitting date.
