Recommended Customer Reviews

Would not recommend Harry Clark Plumbing & Heating (HC) even as a last resort. Contracted them to install two HVAC systems. They installed the ruff and when it came time to do the final, startup,,, they stated several reasons over several phone calls they high lights are,,, they needed more money, they don't work in the area and the original contract was whom they have a contractor with not the home owner, so they don't have to honor it.

We have had very good service from HC. The latest was during the recent cold snap. Our furnaces were down and we called on HC, who sent someone out the next day. He was on time, explained exactly what was wrong and how he was going to fix it. Best of all, he did fix it for a reasonable price.

We recently bought a new home and had to replace the sewer lateral. After getting three estimates we went with HCP and they were very good. I would use then again.

Harry Clark quickly came out to my house to provide an estimate to replace my furnace. The estimate was a lot less expensive than the others. Even though there was a 1 1/2 month lead time to get the work done, Harry Clark squeezed my job in so that my tenant would have heat in the house. They also quickly obtained a permit for me.

Old furnace, old AC and old duct work made cooling and heating our home a Lafayette impossible. Don Marshall and his team at Harry Clark solved all our problems. From the initial proposal to the detail work and the billing our experience was fantastic! They provided extremely competitive pricing and did fantastic work. It was in the upper 90's all weekend and my new AC did the job. I was able to cool the house quickly and efficiently, these guys knew what they were doing and I would recommend them to for your next job!

Buck Court, from Harry Clark Plumbing & Heating, is as good as it gets. He did an outstanding job replacing my faucet with an elegant, streamlined modern style that is exactly what was needed - highly functional and very beautiful.
Thank you, Buck, for an outstanding job today, and thank you to Brian for clearing some time to allow Buck to be here today.
I remain, as always, extremely pleased and highly recommend Harry Clark Plumbing for any type of plumbing, heating/cooling needs.

I had my original furnace from when my house was built in 1986 replaced by Harry Clark Plumbing & Heating. I received proposals from several companies before selecting Harry Clark.
Don Marshall met with me and provided me with the proposal within a week. I did have to wait a while for my furnace to get replaced due to the amount of work that they had already scheduled.
The installers arrived on time, lined my carpet with plastic to keep it from getting dirty, and completed the installation within one day (as I had requested). I did have a couple of minor issues, but Don was very good about getting my issues resolved. In fact, when a service representative (Pete) returned to fix the minor issue, he was extremely helpful, and also went out of his way to help me with an added feature with my new furnace and thermostat.

I have really enjoyed working with Daniele and Jason for one of my properties in Oakland. Not only do they know the technical side of plumbing, they are personable and courteous to my team and me.
Thanks again guys, it's not easy to find contractors you can trust!

Great customer service.
I woke up this morning with a clogged toilet now I don't.

I had a clogged toilet and I called Harry Clark and they came out the next day and was able to fix the problem in minutes. I had also used Harry Clark last year to have a new sewer line replaced. They did an excellent job!!!
If you are in need of a plumber you must contact Harry Clark Plumbing and Heating in Oakland to get the job done right and at a reasonable price. Jason is the best.
