I recently used IDM for a replacement composite front door and french doors at the rear of the property. From my initial contact with Kevin, to him attending to discuss my requirements, through to dealing with Dave and the guys who called to fit, they were nothing but friendly and very professional and all at a great price!

Kevin helped us make the right decision, without being pushy in any way and the two guys who installed the doors had a bit of a job on their hands but were courteous and hard working throughout.

I am thoroughly pleased with my new doors and have already recommended Kevin and IDM to friends.

Ms Lisa Lake
I was wary about buying the windows as you hear so many stories regarding the sales people and companies, but I have to say IDM were so professional. Within a couple of hours I received a call from Kevin to arrange an appointment for the very next day. During the appointment Kevin made some suggestions but was never over the top pushing the sale, when they say you buy people this is so true, I had 2 other quotes and wouldn’t consider them due to the sales people. I had all my windows and a door replaced, the fitters were professional and punctual and always checked I was happy with the finished product. The quality of the products Is great and I have received numerous compliments. Thanks.
Miss Tara Looman
I had an initial quote from Everest and was very disappointed by the price and service. I then went through a ‘recommend a tradesman’ site and within ten minutes Kevin from IDM was on the phone. The following day he came round for a cup of tea and an hour later we were shaking hands on a deal for a new composite front and back door. The doors have now been fitted and they look amazing. From the very start, the professionalism of Kevin, Dave and the IDM team has been first class. My wife has now insisted that I have Kevin back over to quote on new windows! I would highly recommend IDM and if you want to contact me to discuss in person please ask Kevin for my number.
