After having quite a long wait for my new door (problems with supplies) it was fitted last week. Fitter arrived on time and fitted the door efficiently. He tidied up after himself. I was very pleased with the result.

After sales care is non existent...I bought Windows and a composite door approx 4yrs ago. The door white on the inside, green on the outside. Within a few weeks the green paint was coming off. I spent over a year corresponding with them , nothing was done about it. I eventually gave up. Some of the sealant has since starting coming off which I have not told them about...what's the point.

CDM Waterfoot fitted my new windows and doors. High quality products. Great service. Especially from Adam in sales (no hard sell, great ideas) & Steve the installer, high standard of work. No hesitation in recommending CDM to others.

Really poor service. I have all my front windows leaking and they dont care a jot about repairing them, even though they started leaking less than 2 years into them being installed and are under guarantee.

Had a new porch and 8 windows fit by cds. Excellent service from Adam who came to give us our quote and was helpful with ideas and suggestions through to the fitters. Sorry can't remember the names of the porch guys but they and Steve who has just done the windows were brilliant and would happily recommend to friends and family.

I can't speak highly enough of CDM!
CDM recently played a big part in extensive work at our home replacing windows throughout including uPVC sash windows and two arched windows, creating a bespoke structure to replace the old porch / bay window, and constructing a new orangery to the rear of the house with the most dreadful access imaginable. We are delighted with the finished result.
As the work progressed we found that none of the usual tradespeople stereotypes could be applied to CDM. They arrived everyday as expected or earlier and didn't leave until the days work was done. Their installation

Brilliant service, great price!
We have had all of our windows and doors installed by CDM over a seven year period.
We wanted a company that was honest and reasonably priced. Not the type of company that tell you an inflated price and then see if they can get it cheaper for you!
They were professional through and through. Adam the sales rep was brilliant. He listened to what we wanted and gave us informative suggestions on what would work. He would work with us to keep us in within budget. At no time did we ever feel pressured nor did he try to upsell us something. Amazing guy!
Also I'd like
