"MJD have undertaken the mechanical works on several projects I have managed and are currently carrying out the upgrade, refurbishment and new build at Gloucester road Medical Centre, I have always found MJD to be very professional and proactive, there engineers are reliable and conscientious there work is very clean and methodical, wherever possible I will use MJD on future projects, I would recommend MJD for all types of mechanical works."

Kevin Campbell mdgroup

"I have worked with MJD on many projects in the past, the latest one being we had a toilet and shower room refurbishment project, the vast majority of which required mechanical alterations and ventilation design input. This project was based on a tight budget and programme and was worried that MJD would not be able to meet these high demands. MJD soon put my mind to rest with their expert knowledge and professionalism towards how they approached their work and meeting deadlines set. I was very happy that we were able to meet the required programme and come under budget. I will be looking to use MJD in the future and would recommend them to anyone who requires any mechanical design and works on their project."

"Truly excellent service. Worked like Trojans and did a great job. Invoice was exactly as expected, not inflated half way through the job and less than many other quotes. Need a firm to trust? Look no further, MJD won't let you down."

Neil Bradbury FM Client

"I have worked with MJD several times and have been very pleased. They have acted professionally, communication is excellent and variation and financial tracking is current and regularly reported. They are a friendly company and very well suited to our feel and ethos. MJD seem to be capable of adopting both smaller projects where a degree of ongoing maintenance is required, and larger projects under more challenging conditions and environments. I will certainly be working with MJD again!"
