Really good people.
Dan has worked for me for years. His guys are 1st class! Recommend!

Dan is not only good at what he does, their prices are always good. They have re-piped my first home in 2003 and been using every sense.

I have been using Hannegan plumbing for many years. They continue to impress and delight over and over again. Very responsive, courteous and professional, not to mention honest and trustworthy. If you want the best make Hannegan Plumbing your first and only call. You won't be disappointed. Dan and Lynn, thank you for the great service and work! You are the best! Cathy W.

Awesome quick service! Great owners, great employees. They have been in Dana Point a VERY long time.

These guys came in and did a whole repipe for us. After several leaks over the years we decided this was the way to go. They even let us make payments.

I called Hannegan Plumbing and reached Nancy who was great in taking my information and scheduling an appointment to replace my kitchen faucet. I called late in the afternoon and Nancy was able to schedule an appoint early the next day at 7am. Tom arrived promptly at the time promised and went right to work and did an absolutely fantastic job. Tom is a really nice person and a knowledgeable plumber. I felt the cost of the work was fair and I appreciate Hannegan does not charge a fee to come out and determine what work needs to be performed ...in other words no hidden fees, etc.

Hannegan Plumbing is amazing! Highly recommend them! We had them fix and update our master shower!

Hannegan Plumbing saved me AGAIN. I have a rental unit and this time it wasn't my tenant's fault, like previous tenants, but my HOA contracted plumbers that turned off the main every day for three days. I was never even notified, but my tenant certainly felt the disruption. And then when they finally turned the water back on, of course it blew out my water heater.
So, I speed dialed Lynn and Nancy in the office, who always look after me, and coordinated a quick response visit since the reservoir for the water heater was overflowing and dripping into my airduct below. They were there in record time.
We agreed I needed a new water heater and they took it from there. Great price, no surprises, and they ensured that everything was working before they left. It is such a comfort to have a service provider I can count on, and know that I won't be taken advantage of. In fact, they are very reasonably priced, they tell you what it will cost and stick with it. No nickel and diming. They wear booties, and cleanup after themselves, and are so professional.
Thanks guys!

Re piped our whole house, did the plumbing on our bathroom and kitchen. Needless to say Hannegan is our go to plumber. Always friendly, family run and attentive.

We received excellent service from Hannegan Plumbing yesterday.
The project was to replace an old water heater with a new tankless water heater.
Chris and Mike gave us an estimate before lunch, let us shop around a bit, and came back when we called to tell them they had given us a very fair bid. They started after lunch and finished in the late afternoon. We got a great tankless water heater with little inconvenience, and at the price we had been quoted.
