What customers say
“Had a great experience with The Irish Plumber this week. Called on Tuesday afternoon for a problem with our main drainage stack, Sebastien arrived Wednesday morning and the problem was fixed before lunch.”
“Micheal of Irish Plumbing has done several projects for us in the past 5 years. They ranged from the replacement of the main sewer line due to collapsed cast pipe to replacing the kitchen faucet. Work thoroughly and professionally done and on quoted budget.”
“We had an unexpected sewer drain issue and received prompt and quality service from the Irish Plumber. He explained everything very well, rectified the situation, and gave us some good options. Very satisfied.”
