10 Fixed kitchen tap
Posted 26 February
Great service from start to finish. Mark quickly diagnosed the issue with the worn-out valves in our kitchen tap and fixed it efficiently with minimal disruption. He was punctual, professional, and left everything clean and tidy. The tap works perfectly now. Highly recommended.Verified reviewerJob location: CR6 - DDavid F
10 Excellent, highly knowledgeable and experienced plumber and heating engineer
Posted 18 February
It was delightful to find a local tradesman who was so professional and responded very rapidly to the problem. He then quickly sourced the parts required for a cylinder replacement, sensibly recommending a new immersion heater and thermostat be fitted at the same time as they were > 20 years old. The work was done within the price initially quoted and great effort was made successfully to protect our brand new carpeting. We are planning to cancel our insurance and use MJA for any future work due to this excellent experience.Verified reviewerJob location: CR3 - DDamien R

Mark came out to us even though it was late on a Friday, in the run up to Christmas.. Despite being faced with a tricky job, he found a way to sort it out for us and did so quickly and without mess. We were very happy with everything.Verified reviewerJob location: RH910 Shower fixed
