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.

After a collision damaged our bay window while on holiday, we called KJM for help, they couldn't have been more helpful! First they went round to the property and made sure the property was safe and secure, then Paul made a plan for repairs. Josh and Charlie carefully removed the entire bay and replaced the damaged parts, I can honestly it is as good as new! Absolutely delighted! Recommend KJM

I was very pleased and most impressed with the quality & finish of the windows and doors, plus I couldn't have wished for a more polite, friendly and competent team of installers. Definitely a 5 star installation.

Josh and Charlie came to fit our new bay windows on Tuesday. They arrived on time and were polite and professional. They worked hard all day and got the job done in good time. They cleaned up and left everything spotless. We would highly recommend this firm.

I would recommend KJM Group highly. A local company where the customer is clearly at the heart of their business. From the start to finish those we came into contact with were nothing but courteous, helpful and reassuring. From Lee who talked us through all our options to the wonderful team of fitters, we felt listened to, respected and considered. A particular mention has to go to Josh and Charlie who were with us throughout the whole fit.

They were an absolute pleasure to have and a real credit to the company; knowledgeable, extremely polite and thoughtful and went above and beyond to help us out. Thank you and we won't hesitate to contact you again in the future.

We have used KJM to fit all our new windows and they have been excellent. From the sales to the fitting, I would highly recommend KJM. Their customer service and product/fitting quality is the best I have seen. Very satisfied. A big shout out to Josh and Charlie who fitted our windows, very professional and friendly.
