What customers say
“I highly recommend The Irish Plumber, as Michael, Seb and Thomas have all provided honest, timely and excellent service over the years. Thank you for the peace of mind that comes with knowing my home’s water issues will be fixed quickly and properly.”
“I have called on the Irish Plumber to do several jobs for us--one was a big job of replacing the stack, our old cast iron drain, which took two days, and twice now for small leaks in copper pipes that took about 30 minutes each. They have always been professional, knowledgeable and friendly.”
“We were very pleased with the work that Thomas from The Irish Plumber did at our house. It was a complicated fix to address a leak in a tight spot, and Thomas did a great job. We received a prompt response to our call and pricing was discussed up front - no surprises.”
