We are very pleased with the work that was done. There was a quick response to the job that day via a telephone call. An appointment was scheduled for a couple of days later and the work was started early that day & completed that same day. The workers were on time, polite, knowledgeable and proficient. They promised to make a visit a week later to remove the supportive structure and did exactly so yesterday. I am very pleased with the work and their professionalism.. i highly recommend them. Well dodone

Wojciech was brilliant. Communication was excellent from beginning to end. He responded quickly and his quote was more than reasonable. He turned up on time and cleaned up after himself. It was a pleasure to do business with him. I have already recommended him to family and friends.

M&M Construction did a fantastic job and gave us exactly what we had wanted. From the start, they were easy to work with and understood our needs completely. Even with a few changes along the way, the job remained on schedule and on budget. Their advice was really helpful and the standard of finish was very high indeed. We had access to running water and a working oven throughout the entire process which was very much appreciated and the site was tidied at the end every day. Would highly recommend them.

I can fully recommend JM Builders. They always turn up and are very good at working on any problems. They also are very willing to make sure you have what you want. I decided to ask them to wall paper as well and everything about this was discussed before it went ahead. I am sure I will be using them again.

James is a pleasant young man whose standard of workmanship is very good. He understood the requirements of the job - transforming a very ugly toilet into an inviting one - he worked very hard to meet expectations - to which he succeeded. We have already identified further jobs that we wish James to undertake - and would not hesitate in recommending him.
