Recommended Customer Reviews

Mr. Mulhearn installed a Toilette today, he was very spare of speech, very focused, but friendly and fast. The job was tidy, and he gave some advice at the end on saving the box, and usage of the fixture. Would i use again? Yes!

David, I believe was his name, was responsive when called and was immediately available to stop by when asked for availability. He said 4p and arrived around 3:40p.
He quickly diagnosed and solved our issue with the clogged drains. His equipment looks up to date, cleaned, and he removed 2 feet of root from our mainline. Haven't used a plumber before so can't comment on value or price. The service was great, friendly, and professional. He made sure to clean up any mess that was a result from the work done.
Overall, would definitely recommend.

This is going to be an odd review
The first time I called Mulhearn, they quickly and efficiently came by and gave me a quote. While I went a cheaper route (pvc), I still appreciated his quick response and advise
The second time I called, it was for a water leak emergency. When I got home, I found out it was for an overflowing toilet and a plumber was not needed. I immediately called Mulhearn back to cancel the call. They were already leaving for my call, so they canceled the visit
Both times that I called, they were prompt, courteous, and understanding
While I never actually paid for their service, I will definitely do so once another opportunity comes up

I called Mulhern Plumbing and set up an appointment with ""David"". The appointment was set for the next day at 9:00am. David came by right at 9:00a. I had a leaking shower valve and needed the shower head replaced. David explained what needed to be done and quoted me a price. He was neat, complete and honest. I highly recommend MULHERN PLUMBING ! ! !

David was quick and no hassle. I called him for help and came out within the hour. I would highly recommend his service to my family and friends.

Reliable. Trustworthy. Honest. Knowledgeable. Experienced. Professional. Do you need anything else when looking for a plumber!? Dave has done work for my parents over the years and when I bought a condo, he was the first person I called for assistance in some plumbing issues. More recently though, when I could hear running water, but no water in sight, I called him right away! Within a couple hours he was at the condo and able to diagnose what/where the issue was. In addition to the large issue at hand, there were a few other issues he noticed that needed to be addressed. Some work was done immediately and he came back the following business day, first thing in the morning to finish the work. Highly recommend Mulhearn Plumbing. Thank you, Dave!!!

He came to my house within an hour, fixed the problem, cleaned up and did a great job all for a reasonable rate! Thank you!!

Great guy, fixed my sink... And had a fair price. Anyone looking for a experienced plumber look nowhere else!

David Mulhearn, the owner, is an extremely competent and accomplished plumber. He executes efficiently with the most up to date tools. He did a gas line re pipe when we detected a gas leak. Subsequently, he did 2 more gas line repipes to prevent the aging pipes with equal efficiency. He is a real professional and answers your call and arrives promptly at his scheduled time.

Our second bathroom sprung a leak. Water saturated the downstairs ceiling and began dripping on floor below. OUCH!!
Needed a plumber FAST. Yelpers suggested Mulhearn Plumbing. Dave answered and came out right away.
He found the leak pronto and fixed it.
The next day I still saw water on the bathroom floor. Called him again. He came right away with a female apprentice. She helped him with a few preliminary tests. Again he found the problem right way . . . water from the shower head was leaking into the walls through a loose faucet. Just needed caulking, which I did myself.
All's well again.
