    Fitting a new sink and tap

    The job was bigger than I had thought because the worktop required cutting and new pipes fitting because I picked a deeper size. John made it look effortless. Great job!

    Vanity unit install - John is amazing!

    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!

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
