Please stay clear of the people associated with this company. They are complete crooks and liars. The project started well for the demolition, but the build was riddled with delays; JM Construction needed to be more honest with its financial situation, even though we were from the start. After about two months, the schedule of work went out the window Now there is a quality issue, as we are finding works not completed on the schedule not completed or substandard. There has also been no building inspection since May 2024; when asked for documentation of works and use of material for building control, there was no reply. They have now gone into liquidation; we cannot get a warranty for items installed as there has been no response, even to the administrators dealing with the liquidation.

I cannot recommend this company at all. We contracted them to convert 2 flats in E2 into a family home the value of £388,000. We had nothing but trouble with them once they started, loading out our garden with waste from other projects and second hand material to use for insulating the roof and plaster boarding the partitions. They used unskilled labour so the standard of the works was not an acceptable level. Everything they built was not to specification and had to be removed from the property at a cost of £220,000.00. We are currently in a legal dispute with this company so we are still experiencing the effect of coming into contact with them.

We hired JMC to build a single storey extension and renovate the ground floor. The work was unexpectedly subcontracted in its entirety to a team who could not meet the quality expectations we had or were promised. There was a 3 month delay on a 3 month project and even with that extra time, we're left with a bathroom that looks like it's several years old, an extension riddled with mistakes in its structure, as well as leaking chimney breasts and radiators. The finish in places, honestly looks like a child did it. Their warranty is practically worthless, they ignored our requests for repairs for so long, we had to raise a dispute, during which they repeatedly misled the mediator and refused to take responsibility for any issue they couldn't fix with a handyman. We are now considering legal action. An awful experience from start to finish. EDIT I was happy ignore this response from JMC, but with the heavy rain we had a few weeks ago, the extension they built for us has started leaking in two places, both areas that had leaked before and been "fixed" by JMC. On top of that, where the top of the extension roof meets our spare bedroom wall, water has started leaking through the bricks. If you're still considering using this company, feel free to get my email from them so I can show you firsthand the quality of their work.

Avoid this contractor at all costs, James and his method to construction are dangerous and verging on the illegal. I have had to terminate my contract due to his shoddy work and endless delays, just say no!

We had a fantastic experience with JM Construction. The team were easy to communicate with, very knowledgeable and easy to work with. they completed our project ahead of schedule and did a fantastic job. would highly recommend!

we had a basement installed in our garden by these guys and could not recommend them more, they are polite, friendly and professional. they kept us updated every step of the way. very pleased with the outcome and would use the again.

We used this company in 2016 to renovate our property in Wimbledon and again this year to do the same in our new house. They are very good at what they do, the work they do is top class. Highly recommend

We used this company for the construction of our kitchen project. Unfortunately it did not go well. The standard of work is very much below the standard we were promised.

Very pleased indeed. Good pre- sales experience and although I am a "layman" in terms of building work I believe the quality of workmanship for what we have had done has been really very good. Business owner is very responsive but like all construction contractors timings sometimes slip - but everyone knows that don't they?

James and the guys from JM Construction have recently renovated our kitchen/dining room, back room and bathroom. This is the second time we have used JM Construction and yet again the work was done to a very good standard, in fact it has transformed our house !! James’ knowledge also helped us choose the right kitchen / flooring and source worktops etc... Whilst we had an idea of what we wanted, he helped bring it to life. They are trustworthy and very tidy which takes the stress out of getting the work done!
