Harry Clark Plumbing & Heating

Had H. C. install new York furnace 5 years ago and have had nothing but problems since. Spent 1700 since trying to keep it running.Now I have the same problem as last year. They had no follow up after they installed it. Nothing. They left plastic all over my crawl space. I wouldn't suggest using them. Also had them do some repiping and found that they didn't use the proper size in part of it. I looked under the house myself....the had no response to my letter about the repipe...

Harry Clark was referred to me by an old-time Oaklander for my new heating system since he has used them before and was happy with their service and work. I called and Don Marshall came out very promptly and the conversation I had with him was one of the most intelligent and informative contractor talks I've ever had. No hard sale, straight, honest, and he ran down a comparison of different furnaces, their pros and cons. No question is too small for Don; he answered time patiently and added more information than I'd have anticipated. He's also very knowledgeable when it comes to home heating and installing heating systems, as well as other home improvement options. No surprise really; they've been around for many many years, longer than most heating companies.

The subsequent follow up and follow through with my new heating system was some of the best I've experienced. Don kept a polite yet friendly contact with me at all times and answered any question I have over the phone or email, before and after I signed the contract and before I paid them!

On installation: their crew spent three days. Like Don says: ""we'd rather do the job right and spend more time than finish the job fast."" True to their words, they took time to explain things to me. I had a couple of side jobs not included in the contract and they finished them for me at a very reasonable surcharge, happily regarding them as part of the project. Their crew is courteous, on time, tidy, and helpful.

I'm sorry to see so many negative feedbacks on Harry Clark in the area of plumbing. The Harry Clark I know and who came to finish my heating system is definitely pros with a neighborly feel to them. I'd recommend them to anyone without hesitation.

Great job replacing an old water heater and tuning up my pressure reducer valve.
Jon was knowledgeable, timely and neat.

We have used Harry Clark for 10 plus years for our home and business. I request 'Buck only' appointments because Buck provides consistent and great service at our apartment building. He repairs the immediate problem and then checks the other plumbing in the apartment. He is knowledgeable, competent and professional. He diagnoses each situation quickly and remembers what was done in the past in each apartment. Buck is awesome!

The guys at Harry Clark are very professional!

When it comes to replacing old sewer laterals they clearly know what they are doing.

They used the pipe bursting trenchless sewer replacement technique. They stuck to their original schedule, even when the original crew called in sick. They left our front lawn just like it had been before and the driveway cleaner than it has been in years. Their pricing was competitive.

I called Harry Clark to replace a kitchen faucet that was leaking and one of their guys came out but couldn't remove the valves/stems in order to fix the leak. Since the faucet wasn't fixed, he said there would be not be a charge. A few days later I received a $136.00 bill for this non-repair in the mail. They do charge for the travel time/job, even if they can't fix the problem.

I bought a new faucet and called Harry Clark Plumbing (the previous bill had not yet arrived) again to come over and replace the faucet. They were timely but expensive, AND the the valve under the sink leaked right after it was replaced during the repair. This should have been found by the plumber who had just completed the repair.


It's important to check thoroughly for leaks at the faucet/sink level after the plumbing job(or any job, oil change, or whatever). Dry everything with a towel and then run both hot and cold water so that you can see if it is leaking from either the hot or cold valves under the sink., or at the faucet. Putting newspaper under the sink shows the moisture easily but don't put off this important task. Check the work right after the repair and periodically also. You don't want to slowly develop dry rot from a leaky plumbing job and find out about it MONTHS later. Our new faucet job leaked right after Buck finished installing the faucet. and replacing the valves under the sink. I had to have someone else from Harry Clark come out again to fix the leak due to the new repair job.

Gees.....guys. DOUBLE check your work! Buck wrote on the job receipt that no leaks were apparent but they won't be apparent unless you check for leaks. I hope the faucet holds up.

I'd give 0 stars if I could. I bought a house and the previous owner was supposed to take care of the sewer lateral. Harry Clark came and did the inspection. When I called them for information, they refused to tell me anything. Then a few months later, I get a call saying they were putting a LIEN on my property! Supposedly they had a lawyer and had been down at the court house already. I freak out- how did they do $8000 worth of work on my property without me knowing? I call them back after looking into it. Then they decide to let me know that they mixed up the paper work but my property needs $8000 worth of work which I will need to pay for even though someone else promised to pay. I got a 2nd quote- turns out to be a fraction of the price. I would NOT recommend doing business with these people who mix up paper work, lie to customers, and inflate prices.

I live in an apartment. The apartment owner called Harry Clark plumbing to assess the brown water coming out of my bathroom pipes. Plumber Buck Court arrived and began checking the situation. After about 5 minutes, he said was leaving, and would give owner a report. I asked him what he ended up doing in the bathroom. He said he could not tell me because of his business ethics. I asked again (maybe he misunderstood?) He said again in a more huffy tone, you can ask the owner. Interesting ... I told him I'd have never heard of that being a renter for many years, I am only asking what you JUST did. To my statement of ""I have never heard of that"" he smart-assly replied, ""well now you have,"" turned on his heel, and walked out my house saying, smart-assly again, ""you have a great day."" I slammed the door behind him and locked it. Not to keep him out, but to keep me from going out and cussing him. WOW .... To the man who has these upstanding business ethics.... what about your ethics in dealing with people? Specifically the strangers who are at your mercy as you come into our homes. What about your ethics with treating people with regard when they ask simple questions after dealing with issues such as mine for two months? (I live here, pay rent and potentially bath in rusty water ... the least you can do is tell me what the hell you just did?! Not asking for the big picture, cost, ultimate break down) What about understanding that your attitude is as important as your skills when it comes to getting a call back? Which, by the way, you will not from this unit. Unfortunately these guys could be the best out there, but I will never know and will never refer them. This is my experience. Now, I AM going to go have a great day.
FYI -- I also called the company and lodged a complaint. They received it and apologized.

Pretty cool guys, kinda pricey but they seem honest, and knowledgeable. I have recommended them to a few friends. If you have a small job, maybe best to hire handyman, or smaller company. There good for medium to large jobs....

I have used Harry Clark on a limited basis over the past 20 years. They are a professional outfit and back when I first used them (pre-Yelp) they were who you used in Oakland. I used their services both personally and referred to my real estate clients who were new to most of the basic home service people.

What I've found over the years is that it has become harder and harder to refer their company to my clients for the small jobs. If it's a big job, you get ""on the board, but if it is a small to medium-sized job, you're going to wait. And the bids were increasingly less competitive compared to smaller operations. For instance, to check a water heater, that had a few issues, they charge a $160 fee just to come out and do an inspection which isn't applicable to the job later. What the ???

Overall, I found the work of their contractors just fine. However, unless they are doing major work like replacing a furnace, don't bother calling them. There are other companies who treat each job like an opportunity to help and earn your business.
