Water Heater Repair & Replacement in Rockville

When your water heater isn’t working properly, everyday routines can quickly become frustrating. Maybe your shower turns cold sooner than expected, hot water takes longer to heat up, or you hear unusual noises coming from the tank. These problems can have several causes, and they don’t always mean you need a new water heater.

Leahy Plumbing & Heating helps Rockville homeowners identify what’s causing unreliable hot water and determine whether a repair or replacement makes the most sense based on the system’s age, condition, and performance.

If your water heater needs attention, call (301) 652-0478 to discuss your water heater repair and replacement options.

What Our Rockville Customers Say

Exceptional experience all around with Leahy! John answered all my questions when I called, and we got the service scheduled in a very timely fashion that fit our schedule.  Gary, who came out to install our new toilet, was on time, professional, nice and got the job done…leaving zero mess. We definitely recommend Leahy for all your plumbing needs.

Monica F.

We were very happy with our experience with Leahy. After receiving a very high estimate from another company (and paying an estimate fee) for a leaky hose bib, Leahy gave us a free estimate indicating that they could do the same work for a fraction of that cost. The owner answered all calls himself and was friendly and professional. The plumber arrived on time, worked quickly, to our surprise was even able to complete the work without making a hole in the drywall wall, as we’d originally expected. Even more surprising was that the final cost was less than the estimate! We are so glad we contacted Leahy for a second opinion and will definitely choose them again in the future!

Naomi M.

We had a great experience with Leahy! After receiving a high water bill, we called Leahy and they came out same-day. Our plumber, Blaine, was knowledgeable, courteous, and right on time. He resolved the issue and the pricing was fair and transparent. We’ll continue to use Leahy for our future needs!

Alexander M.

I love Leahy Plumbing. It is the kind of company, with the kind of service that feels like it shouldn’t still exist in 2025. Recently I needed something done quickly, I called in the morning (talked to a human) and they were able to very quickly come to my assistance. Thank you to John and the whole Leahy team!
