Recommended Customer Reviews

I have used Mulhearn Plumbling for years now. He is super nice, always does amazing work, is super quick and efficient, and reasonably priced as well. Best of all, everything he fixed still works! No patch jobs or shady repairs. If Mulhearn fixes it, you know it'll work well for years

Used David a second time to replace a garbage disposal. As before, he was first rate and quick.

I called Mulhearn Plumbing to fix a plumbing problem. He came out right away, gave me a quote and went to work. He was very honest, the price was reasonable and found the problem right away and fixed it. The problem was from the prior plumber (not hired by me as this was a new home purchase) who fixed a plumbing issue and left a rag in the pipe before sealing the pipe. The plumber who did that, would not even come out and see why the plumbing stopped working after he ""fixed"" it. This is why you need a plumber you can trust like Mr. Mulhearn.

David is very helpful and knowledgeable with his craft! I wanted to support local business owners and it can't get local than this. Diagnostic abilities and workmanship is superb!

Had an emergency with a leaking shower, and called him at 8:30 a.m. He showed up an hour later, and spent three hours running up and down the steps, finding and fixing the leaks. He was very patient with all my questions, and pleasant. David didn't sugar coat the problem (it wasn't JUST the shower, of course), the cost, or the solution. I really felt like I could trust him. I'd DEFINITELY use David again.

David did such a great job and really exceeded my expectations. I have had my bathroom faucet repaired multiple times throughout the years but it was never fully correct. It would be ok for awhile and then start leaking again. Or we could only get really hot water. Two weeks ago the leak behind the bathtub had caused water damage throughout my condo. Something that 4 recent inspections had mis diagnosed. They were in the beginning phases (estimations etc)of fixing the damage but it would have kept happening because of this leak that David detected and fixed. David replaced the valve and installed new hardware. The shower has never worked so well! He was honest in his recommendations very thorough in his work cleaned up the site and showed up on time! I love the new hardware he choose as well. I would definitely call Mulhearn Plumbing again but he did such a great job that I may not need to.

The time when you need a neighbor for help and he just so happens to be a plumber.... Hey David next door can help! Fast, professional and trustworthy like the neighbor next door. Inspects, informs you of the problem, then provides solution options before quickly resolving your plumbing issue.

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
