Used MML Plumbing for the first time today. Administrator in office was easy to deal with, efficient and helpful. Plumber arrived on time as arranged, fixed the problem and explained what he had done. Quick, tidy and courteous worker. What I also especially liked was that I was given an actual confirmed time when he would arrive and not one of those two or three-hour 'window slots'!

MML Plumbing successfully completed the installation of our heating system in our expansive 8-bedroom residence. The placement of the boiler and cylinder was expertly executed in the basement. They meticulously laid new piping throughout the house to facilitate radiators and hot/cold water faucets. The recent commissioning of the system has resulted in its exceptional functionality. Their impeccable organization and absence of any delays were notable. We definitely plan to engage their services again in the future.

In North London, it can be hard to find a company that you can trust and provide quality work. We called MML Plumbing to install a system boiler and a hot water cylinder. The installation was done in a few days, and now everything is fine. They left the area very clean. I highly recommend them.

Central heating leak search

This a quite common leak in North London homes. With our smart leak detection equipment, we can find any leaks easily. Our engineers can trace and locate the leak in the heating pipe that usually runs underneath the floorboard. To find leaks we use an acoustic leak detection device and also a thermal imaging leak detection to trace and locate the pipe. We can detect leaking underfloor heating pipes in the concrete slab and we find solutions to repair the leak.
After our expert plumber has conducted a leak investigation and located the leak, we take steps to secure the area and ensure safety. We then give you a detailed estimate that includes the duration of the repair and the cost of materials, giving you a clear understanding of the work that will be done and the associated costs.

Main water leak detection

If you notice water leaks from the main pipe, that will be easy for us to find. Probably you can hear the water spraying onto the floorboard but you can’t locate it. If you have only a dripping pipe somewhere inside the brick, you can call our smart leak detection expert and we might be able to fix the pipe on the same day. We only need small access by drilling a small hole in the plasterboard or brick in an unseen area. This hole is around 1-2 cm wide. Through this drilled hole, we can insert our small leak-detection camera.
