Recommended Customer Reviews

Kitchen sink was clogged and garbage disposal was leaking. Called David, Mulhearn Plumbing, and he came out within an hour and fixed the problem. He was knowledgeable, professional, friendly, and courteous. I will definitely call David for future plumbing problems.

I had a great experience with Mulhearn. David was quick to reply and diagnose my issue. He gave his thoughts on the potential problem and referred me to a potential solution. Although we did not end up needing service after all, it was Mulhearn who was professional, knowledgeable, and authentic in giving me sound advice that was in my best interest. I appreciate people and companies that look to do the right thing and help others, even when a service or payment is not deemed necessary. I highly recommend giving Mulhearn Plumbing an opportunity to cover your plumbing needs.

We had a leak and we called David, and he was incredibly understanding and gave us great advice. He gave us a few options over the phone, even ones where he would be turning down our business! Honest and transparent, will definitely call him for any future plumbing needs (hopefully this doesn't happen though lol)

I highly recommend Mulhearn plumbing! David was very responsive and easy to deal with. I expect to use him for any future plumbing work I need.

I called David on a Monday, gave me quotes to replace the water heater, or to install a new tankless water heater (I went for the cheaper one lol). The very next day, my water heater was replaced, hauled away the old one and paid the price that was promised, no extra fees or taxes. Highly recommended!

I needed a plumber for my clients who just purchased a home and Mulhearn was so quick to respond and go out to give an estimate. Once we received the keys he immediately was available to perform the work for my clients. Such amazing customer service! So happy I was able to find him.

I called Mulhearn and David came down immediately, initially I thought he was quoting high, but when he saw my sump pump, which was not working, he fixed it and solved the issue by not replacing the motor which other plumbers were planning on doing it, David saved lot of money and suggested other better things to do.... Definitely recommend this person for future plumbing issues....

Excellent service! Fast, reliable, responsive and honest. Very glad to have come across his services and will be calling again with future business.

He responded quickly to my questions. He came on time and didn't take long to finish the work. Friendly, courteous and professional! Would use him again if needed!

Had a small job regarding the dishwasher, and David came over fast, quickly finished his work and was off. Thanks ! I love when people are straight to the solution.
