    Excellent refurbishment of my bathroom

    Bathroom Renovation - I employed RM Plumbing recently to carry out renovation work on a bathroom. The job was completed efficiently within the agreed timescale and according to budget. I was impressed with the high standard of workmanship displayed by Ryan and the team, which was first class, and by the way they found solutions to the few minor problems that came across during the course of the work. I was also impressed by their efforts to minimize the dust and inconvenience caused by the work. I would employ RM Plumbing again when next I need a plumber. Mel evens

    Central Heating System and New Bathroom Fab Job! 🙂

    Ryan & the team installed me a Brand New Baxi Combi boiler with all new Radiators and all new pipes and Nest Learning Smart Thermostat Device that I can control from my IPhone!! Also my bathroom was totally ripped out at the same time as it needed updating badly! They quoted us a fair price for the entire job and has their own plasterer and tiler. Now have a lovely Victorian style bathroom and Shower on the wall all wall are fully tiled from floor to ceiling with white brick effect with charcoal colour grout I wish I could put a photo on here to show it off 🙂 I will be recommending these friendly tradesmen to my friends and family in the future also forgot to say they made sure we had a working toilet and water before they went home.
