I am William/Bill Lavoie, the owner and contractor at Dynamite Plumbing. As a third-generation plumber hailing from Los Angeles, I strive to maintain high service standards. I am excited to engage in new projects and meet new clients, while also reconnecting with familiar faces. Thank you for stopping by!

Recommended Customer Reviews

Very friendly and exceptionally reasonable when other plumbers quoted 2x-3x seemingly arbitrarily for a replacement and install of a tankless water heater. Dynamite will be my go-to plumber from now on.

After getting screwed over by a previous plumber I was very skeptical of hiring another plumber to replace all of our horizontal pipes in the house. When I called Bill to ask him to stop by for a proposal he showed up the same day, was super friendly and gave us a reasonable proposal compared to the prior one. The overall project took nearly a week, but Bill and his team we're super professional, easy to work with and even helped out with other plumbing realted items while they were here. I highly recommened Dynamite Plumbing for all your needs. I for sure will be keeping them on hand for all future projects.

I would never recommend this company to anyone. Lavoie left the drain sweage pipe unconnected ( he was supposed to reconnect it) under the house, which caused erosion, foundation problem, financial lost and health problems. Avoid this compan. You may also check BBB - this company has official complains.

Bill and Lee are the best. They will work hard and find creative solutions. They're great guys, too. A pleasure to work with them. And everything is working fine :)

The review I posted for Dynamite Plumbing was for Jared Miller of Dynamite Plumbing in Simi Valley. Not for this company out of Pasadena. Do not do business with Jared Miller in Simi Valley calling himself Dynamite Plumbing. They are not the same company. My apologies to William for posting a bad review on this page.

Bill also does other handyman and construction work. He put an attic access in our ceiling in no time flat, cleaned up after, and even the tenants commented on how great he is. More than reasonably priced. Highly recommended.

We called Dynamite Plumbing based on an ""A"" Angie's List Review.
Unfortunately, they did not do an acceptable job. They bid the job verbally and at the end doubled the price. The job was to replace irrigation pipe connected to the main water line. They removed metal pipe and replaced with cheap PVC (without telling me) and it leaked after two weeks. They came back and fixed it and it leaked again. I had to call another Plumber to do the job correctly, paying twice for the same work. The second Plumber told me that Dynamite Plumbing did not use the correct materials (PVC) for this job and that I was overcharged for what they did. I am a senior citizen and feel I was taken advantage of by this company. I have requested that Dynamite Plumbing reimburse me $500 (half of what they charged me) based on documentation by two reputable Plumbers of what the job should have cost as well as Dynamite Plumbing's poor work quality. Two weeks after my reimbursement request, Dynamite Plumbing is still unresponsive.

Bill, the owner came out quickly and did a quality job cleaning out toilet drain problem. He had hi-tech equipment and discovered the real issue: root damage farther out. We have been using another plumber until now and had been avoiding the real problem but this company is so efficient and affordable that we will be solving this problem at the roots!

I had a catastrophic failure with my water heater at about 6 AM on a Friday. I used Home Advisor to get three quotes. The first company to respond was Dynamite Plumbing at 7:30 AM. They were at my house at 8:20 AM.
Everything Dynamite told me, matched what I already knew about tank & tankless water heaters and the research I did online while I was waiting. So I knew I wasn't being bamboozled.
He offered to replace my 40-gallon tank water heater with a similar one for about $1000, that included everything and they could get it done the same day. Not the lowest price but entirely reasonable.
But then, my wife talked me into getting a high-end tankless water heater. I'm fortunate enough to have three bathrooms. When you have guests, they all want to take showers at the same time. This unit would support that. It would last 20 to 25 years and be more energy-efficient. Normal tank water heaters are good for 7 to 14 years. (Your mileage may vary.)
.
It was more money, but they got it done in the same day, and my wife was happy.
I purchased my house from a flipper about 10 years ago. The flipper went cheap on a lot of things, and I've had to redo a lot basic things. In my opinion, it's always less expensive in the long run to go with real professionals and buy quality.
I'll be doing business again with Dynamite Plumbing.

Husband discovered there was no hot water in the morning.He called Dynamite Plumbing & their rep came out, we talked about a replacement water heater, their rep Bill picked up the tank-less water heater we wanted and installed it. All done in one day! Bill also took the old water heater etc. with him and was efficient and nice to work with. We highly recommend Dynamite Plumbing.
