Windows & Doors (uPVC & Metal)- 25 Apr 2026
We found Marian from CM Fixing after the suppliers recommended fitter proved unresponsive and we are so pleased we did. We have found dealing with Marian an absolute pleasure - really responsive communication, excellent price and he has done a fantastic job for us today. They arrived promptly at 8am and fitted our new doors with no fuss and lots of care and it’s all looking amazing. I would recommend Marian and his team to anyone considering an installation.

Extensions- 5 Nov 2016
Leslie carried out the following works: chemical damp injection to walls on rear extension, reroute down-pipe, repair fracture on rear wall, install gutter hedgehog. Hopefully, this will resolve some of the issues we had with damp, a blocked down-pipe and an overflowing gutter. Leslie arrived on time on the first day but was delayed a few hours the next day. However, the work still was done within two days as expected. Thank you!

Kitchen Fitting- 31 Jul 2019
Can't recommend this guy enough! Pat is a professional from start to finish. He came to quote me for a complete kitchen refit, within a few days he had emailed me a detailed quote and we agreed a date. My kitchen came with many unforeseen problems and challenges but Pat rose to them all. Aside from being a skilled carpenter and a skilled builder he is a great problem solver. He is reliable,trustworthy and very approachable. When I was getting stressed out he would calm me down and reassure me that everything would be ok. Sounds silly but my kitchen issues would have stressed a saint out! To summarise, my kitchen has turned out beautiful! Pat has done the work to a very high spec and gave it the wow factor! I absolutely love my new kitchen and am so happy that I chose Pat to come and do it for me. Look no further!!! Hope he posts my before and after pics on here and you can see for yourselves!

What experience do you have with similar extensions in Sidcup?
