Site Management

We take great care about cleanliness, we ensure that we keep your house and place of works as clean and tidy as possible throughout the duration of the job. We always recommend to view our work and talk to our customers by asking them anything you like about CJM.

We project manage every  loft  from the initial design and planning application process through to dealing  with local authority inspections. We organise all trades, even if you choose to use your own tradesmen we will work with them to our highest standard of professionalism. All our work is signed off by building control, you will be issued with a completion certificate which is a legal document that is required, if you ever come to remortgage or sell your property in the years that follow.

We offer a free survey with no obligation and once you have a detailed working drawing we offer a competitive itemised quotation.

The majority of our work originates through recommendations from existing satisfied customers.

Your loft conversion is one of the few home improvements that can increase the value of your house considerably more than the cost of the conversion itself.

"I deliberately kept quiet the fact that I am a chartered surveyor and monitored very closely the construction and finishes at every stage, and would like to say on behalf of myself and my wife how pleased we are with the final result. Great job well done guys!"


"I want to thank you and everyone at CJM for doing such a fantastic job on my loft conversion. As you know only too well, it was an extremely difficult and complex job, and I am in no doubt that no other loft conversion company could have pulled it off except CJM. Once again, thanks for doing a great job. You clearly put the customer first, and that kind of attitude is rare in the building industry."


"The quality of your work is first class. As you may remember, our son-in-law is a Professional Tiler. He helped us complete some of the decorating on our conversion. At ever stage that he made measurements to fit tiles, paper, etc. he found without exemption, all the walls, wood frames etc. to be true. He had never come across that in the last 10 years!!!     Thank you..
