Once again a fantastic job well done. I can’t fault this company and the work completed. I’m looking forward to getting more windows altered/improved.
Thank you

JMF have done a super job of replacing our old conservatory with a brand new 'warm roof' version. Easy to talk with and delievered exactly what was promised. I have used JMF twice now and would recommend to anyone needing this kind of work done!

Would highly recommend JMF Windows. We used them on one of our projects and received excellent service from start to finish. The windows and doors looked brilliant, and they managed to keep to the agreed timescales, helping to move the project along smoothly.

We recently had some of our very old windows replaced by JMF Windows & Doors and are extremely pleased with the work completed.

From the outset, the service was excellent. Paul visited to prepare a quote, which we received the same day. After accepting, Jake carried out a detailed measure and clearly explained the process, lead times, and logistics, which was very helpful.

The fitting team were friendly, professional, and respectful of our home - taking care to protect carpets and work areas while keeping everything clean and tidy throughout.

The finished result is excellent. The new windows look fantastic and have already made a noticeable difference to our home.

We would highly recommend them.

We’ve had such a great experience with JMF Windows. The whole team at JMF are all so friendly, professional and genuinely helpful. They gave us great advice from the start and made the whole process really straightforward.

We’re so happy with our new windows and the quality of the work is excellent. We’re already looking at getting our front door done with them as we honestly wouldn’t go anywhere else. Completely trustworthy and a pleasure to deal with from start to finish.

Thanks guys

Absolute exceptional service from start to finish!
We had our dream door for our house installed by JMF. Jake came round to see us and was wonderful to work with. He knew exactly what we were looking for and made the process seamless. The installation team also were absolutely brilliant and highly professional from start to finish. Great communication and time efficient.
We couldn’t highly recommend this company more and I’m glad we found them! Rabia & Guillaume

Fantastic job! I had a door installed in place of a window. Communication was excellent throughout the job with Jake and Paul both visiting for measurements and to check things over before Dan and Bash did the installation. They were efficient, neat, clean and tidy which is a huge bonus in my opinion and took all the rubbish away. The job took a day and the end result was excellent. I would highly recommend JMF and will definitely use them again.
