Nick O'Grady

Anthony and Alberto came out to check out my extremely old (20+ years) water tank heater. They set me up very quickly with some new options. Dee and Alberto were able to replace the tank heater very quickly. No problems at all, really good experience.

Assistance with Water Heater Issues Harmon Plumbing Services, Inc. has been excellent to work with—professional, responsive, and highly reliable. I live over an hour away, and their team made addressing my elderly father’s water heater issues far less stressful by maintaining clear communication and even responding to questions after hours. Their level of service is greatly appreciated, and I would confidently recommend them. I would also like to give special recognition to Harley D. Thank you for your consistent communication, follow-up, and for recommending an electrician when needed. Your responsiveness and attention to detail truly made this process easier for our family, and we sincerely appreciate your support. Additionally, thank you to the technicians Anthony and Alberto for their professional, timely, and courteous service. Their work and professionalism did not go unnoticed.

I discovered a leak beneath my house, but we couldn’t pinpoint the source. The crawl space was soaked—subfloors and insulation included—and I was genuinely worried it might cost thousands to fix. Anthony from Harmon Plumbing came out to inspect everything thoroughly. Thankfully, he found that the pipes and drains were all in good shape. The most likely culprit turned out to be the dishwasher. Anthony walked me through how to help the area dry out and what steps to take next. He and his team were incredibly kind, honest, and transparent—no scare tactics, no unnecessary repairs, and absolutely no price gouging. They even told me to reach out if the moisture didn’t clear up within a week or if I replaced the dishwasher and had issues again. That kind of reassurance gave me real peace of mind. I originally found Harmon Plumbing through a contractor I’d hired, and they were fantastic then too. This is my third time using them—second time I’ve called them directly—and I won’t go to anyone else. Trust is hard to come by, and I trust these guys completely. That peace of mind is priceless.

Frequently Asked Questions

How long does a sewer camera inspection by Harmon Plumbing take?

Most inspections take 45 minutes to an hour, depending on access points and pipe length.

Does Harmon Plumbing's camera inspection clear or unclog pipes?

No. The inspection is diagnostic and pinpoints problems rather than cleaning or clearing a pipe.

What happens if a line is fully backed up during Harmon Plumbing's camera inspection?

The cameras are waterproof, but murky standing water can limit visibility. The company may briefly clear a fully backed-up line or let the water settle first.

Does Harmon Plumbing offer financing for plumbing work?

Yes. It offers financing through Synchrony, with options for paying in manageable installments.
