Recommended Customer Reviews

Disappointed by OP Plumbing. Called and left a message but no response. The customer service is not there and there is no response back from my experience in reaching Frank. Other plumbers follow-up with you when you call, but not OP Plumbing, neither at the time of the call, hours later, or even same-day. I don't recommend them because of this lack of reliability.

Frank was very professional and answered all my questions even after he had left our house. He installed the Pelican whole house filter and we are very satisfied with OP Plumbing and Frank. I recommend their services to anyone.

Frank was a pleasure to work with and very thorough and professional. Needed a second opinion plumbing inspection for the sale of my house. Frank looked over my entire house, crawled through my attic and made sure there weren't any issues that he could see. I will definitely reach out to Frank if I have any plumbing issues that need to be addressed.

Frank is professional, helpful and nice. I had a toilet that was leaking and he was able to provide the service same day with an affordable price. Worries are now vanished. I will be sure to give him a call for an future plumbing issues.

I'm satisfied with O.p. Plumbing service. Frank made himself available and accommodating to my needs. He pointed out potential issues and explained thoroughly on how to fix them. He's also reasonable with his pricing and doesn't try to sell you services that you don't need. Thank you, Frank.

Frank has helped my family with our plumbing needs for over 10 years. He is always affable, available, and apt. When other plumbers cannot figure out how to solve a problem, Frank always does! He is trustworthy, honest, and always fair in pricing. When we have emergencies, he has always giving his best effort to fit us in.

You will love working with Frank Orduna. He did our kitchen and bath remodel and also installed a new hot water heater. He's punctual, tidy and explains everything to you if you ask. Frank shows up when he says he will and answers his phone every time I call. His prices a very reasonable. He's our new plumber! L & R Valdez

We had an issue with our plumbing on a Sunday, we thought we had a leak coming from the water shut off valve. We called Frank Orduna and he was here within a few hours. He check all of our plumbing and within a few minutes was able to determine that the leak was coming from our water heater and able to replace the water heater hose very quickly. He is an exceptional plumber and very knowledgeable plumber. I highly recommend Frank and his prices are very reasonable.

If you need a good reasonable plumber, call Frank Orduna. He did a great job for me with repairs on my main drain line. And he removed and replaced a gas line that was leaking from my friend's house. I highly recommend his services. -Don

I am very happy with the work performed by Frank at OP Plumbing. I have been impressed by his attention to details, problem solving skills and how each time I have hired him, he has gone the extra mile. On one of his jobs, he requested the measurements of my new washer and dryer (he even volunteered to stop by the store I purchased them from to take the measurements himself) to make sure the plumbing would be in the exact spot to make them as flush to my wall as possible. Considering they are going into my closet, that was extremely advantageous. I also appreciate how helpful he was installing a Restoration Hardware shower valve that I had purchased. He was concerned about a piece on it, so he called the manufacturer and had a replacement part sent to me. His last job at my home was to fix a serious problem that a previous contractor had caused. He did an exceptional job on that as well. I have enjoyed his level of professionalism and will continue to use him in the future. Thanks Frank!
