    Vanity unit install - John is amazing!

    Posted 09 March

    John was absolutely brilliant! We had a new floor-standing vanity unit installed. He came on the same day to inspect the job, quote, and carried out the work to a very high standard. I couldn't be more happy with the job and will be using John for all plumbing issues in future. Thank you!

    Excellent Communication and Quality Work

    Posted 20 September 2025

    John was hired to remove a sinkerator unit from a property I just bought, and he was fantastic. Communication was clear from start to finish, and his work was neat and tidy throughout. I really appreciated how he kept me involved in all decisions and took the time to explain things so I learned along the way. I’d highly recommend him — he’ll be my go-to for any future plumbing jobs.

Thanks for taking time to look over my Checkatrade site, my name is John Giblin.

I hold a registered gas engineer license and hold qualifications for plumbing also.

I take pride in my work, and I like to treat others as I would like to be treat myself, so I do all jobs with this as my example.

I began my career as a plumber in 2001 and started my own business in 2004.

We cover all aspects of plumbing, from blockages through to full boiler installations. We do bathroom and kitchen installations including all the tiling etc if the client wishes.

There is no job large or small, that we are not willing to do in order to keep clients happy.

Please feel free to call if you would like a friendly and thorough service.

Thanks for looking.

John
