About
Bathroom work done properly, by the person you actually speak to.
JM Plumbing Services is run by James Marr, who brings over a decade of hands-on plumbing experience to every bathroom installation, renovation, and repair we take on across Cardiff and the Vale of Glamorgan.
We don’t own a showroom, and we don’t carry out gas or boiler work — our focus is bathroom installation and renovation, tiling, LVT and vinyl flooring, and general plumbing, done thoroughly rather than spread thin across everything.
