10 Excellent Communication and Quality Work
Posted 20 September
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.Verified reviewerJob location: SW6 10 Saniflo repair / installation
Posted 30 June
Excellent service - John was reliable, effective and a great communicator. I had hired someone the day before who wrecked the Saniflo and managed to break it while trying to repair it. John came at short notice the next day - he managed secure a new saniflo and fit it that same day. Service was above and beyond. Would recommend using his company.Verified reviewerJob location: NW610 Replace old boiler
Posted 22 June
John arrived on time, professional & happy to explain what the work entailed. The job was more complicated than originally thought as it involved putting in a new flue but the work was neat & although spread over two days everything was cleaned up on the first evening & gas turned back on for cooking. John & his mate Ahmed were friendly & polite with nothing being too much trouble. Very trustworthy & I felt safe alone with them. Would definitely use again if I required a Plumber.Verified reviewerJob location: HP2

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
