Meet Graham Johnson, your Darwen plumber.

The man behind G.S Johnson, and the person who'll be quoting, fitting and handing over your job.

Plumber, heating engineer and bathroom fitter.

Graham's business, G.S Johnson, is run from Darwen. He's registered with Gas Safe (no. 225475), approved by Vaillant to install their boilers, and works across a 20-mile radius that stretches from Preston to Oldham.

Handling heating, plumbing and full bathroom refits himself means fewer trades in your home and one person who knows the whole job. It's a big part of why customers come back to him for their next project.

Very happy to recommend Graham Johnson, plumbing and heating services.

My bathroom was a mess, not practical for myself. Graham quoted in great detail what was required to move a bathroom from its current location to another room in the house.

He also gave an accurate timescale for the work, and kept me updated of what he was planning to do each week. Miranda assisted at times, as did Warren, who completed the electrical work. The tiling work is superb, friends and family adore my bathroom too.

Graham was respectful of my property and my belongings. I paid for the work in instalments, to help me with budgeting, but all equipment (suite, tiles, plaster etc) came directly to my property and was stored on site until it was ready for installation.

At no point was I asked for additional money to cover x, y or z as the original quote had been so thorough.

I would be very happy to recommend Graham for plumbing and heating services.

Graham turned our tired and very dated en-suite into a beautiful shower room.

His work ethic, professionalism and attention to detail is 1st class.

Would highly recommend

I met Graham through a work colleague.

Graham came and gave me a very competitive quote for a virtually new central heating system.

From quotation to giving a comprehensive handover when the job was completed.

I cannot fault any aspect of Graham's work.

He always worked to the highest standards and taking time at every point to explain the work as it progressed.

I would have absolutely no hesitation whatsoever to recommend Graham to others.

I have now booked him to do my bathroom later in the year.

I would recommend graham for your heating and plumbing maintenance very friendly and helpful and also very reasonable in price I would rate him 100%

Diamond service from Diamond Guy!
