Fitting of bi-fold doors and front door

We shopped around to find a suitable product from a reputable company and chose KJM. No hard sell, the salesman attended, and was very informative and helpful. As to the installation, Aidan, Josh and Will were very helpful and provided very good advice, were clean and tidy and provided an excellent finish. I would definitely recommend this company and its installers. All in all excellent quality and reasonable price

Top-quality professional installation from the team at KJM. We recently had new Bi-fold doors installed during a new kitchen installation and the KJM team worked seamlessly with the other trades to complete the kitchen replacement. We have previously used KJM for the replacement of all of our windows, doors, conservatory, soffits and gutters in previous years and have always found them to be friendly, professional, helpful and reasonable in costs. We would not hesitate to recommend using Paul, Mark and the team at KJM.

KJM installed 4 windows and a new front door for us. Really everything was faultless. The quality of the products is great, the ordering process went smoothly, and the installation was first class Aiden and Josh were the installers. They worked well as a team, there was no redecorating required, they showed creativity in overcoming any issues in the fitting, and kept me informed at all stages. Everything was also very clean when they were done. Good job!

My new door was fitted sixteen months ago but had an alignment problem. I called KJM who immediately organised an engineer to visit to rectify the issue, all at not cost, even though the warranty had expired. I am particularly impressed with your pride in delivering customer satisfaction, even though my door was fitted around sixteen months ago. This level of pride and commitment has not gone unnoticed. You can be sure that KJM is on my list of top quality companies and therefore receive my highest recommendation. Thanks once again to KJM for a truly outstanding service.

Simon, thank you for taking the time to review our after-sales service. I do believe that the door would still have been in warranty, so I could not let that comment go without a reply to you. However whatever the cause, we do try and maintain the best customer service we can, something that has not been as good as I would of liked during the darkest days of COVID. Hopefully, that has gone. Thank you again

KJM door fitting
Customer Service

KJM were very professional, from the initial assessment and quote stage, through to delivery and fitting. The fitters, Aiden and Josh, had to take out some brickwork to fit the door and were careful to minimise the mess and clean up afterwards. They also came back a second time to fit the trim, allowing time for an electrician to route some cabling. All in all, a first rate, good value, service from a local company. Job done!

My landlord sorted everything with kjm so I can only comment on the workmen that came out today, they are very respectful, funny and kind! They take pride in their work and make sure they clean up after themselves and they are very good around children, definitely highly recommended!

Fantastic service and product

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
