See what steps our team is taking to ensure employee and customer safety during the COVID-19 outbreak and its impact on the Northern Virginia, Maryland, and Washington, D.C. regions.



With over 100 years of experience serving the Maryland, Northern Virginia, and Washington, D.C. regions, the John C. Flood team has earned a reputation for providing excellent repair, service, and installation for HVAC, plumbing, electrical, and home remodeling.


Heating and Cooling Services

Your HVAC system is designed to maintain a comfortable indoor air temperature — no matter the temperature outside! However, even the most sophisticated systems develop problems during months of extreme temperatures. 

At John C. Flood, we diagnose and treat problems from the most common to the most complicated, including air conditioning, heating, and furnace repairs. Our HVAC team is also equipped to improve your home’s indoor air quality with whole home air purifier and air scrubber installation services.


There are several common plumbing problems you might be able to handle on your own, but clogged drains, burst pipes, sump pump repairs, hot water heater issues or low water pressure are just a few of the many cases when a professional plumber is needed.

Whether your sewer line is backing up, your basement is flooding, or there’s a water main break, call John C. Flood. We have the knowledge and experience to handle any plumbing problem quickly and efficiently. Learn more about all our plumbing services.


You’ll be hard-pressed to find a company in the Washington, D.C., Maryland, or Virginia region that has as much experience providing electrical services as the John C. Flood team. Our certified electricians have trained eyes to catch many common electrical issues seen in the home. If you’re experiencing frequent power surges, malfunctioning light switches, or want to install a home generator, our team can help.

We also specialize in updating the electrical systems in your home and conduct inspections to ensure your wiring is up to code. Outdated systems are an inefficient use of energy and can spike your monthly utility bill. Our electricians can audit your home and recommend ways to improve its energy efficiency.

    "Estimator Dan Mayo provided a free estimate and video snake analysis of my main sewer line. He was very nice. I had been told that I needed a full replacement of my sewer drain by a different company, but Dan said that he wouldn't recommend a replacement at this time. It was refreshing to hear a plumber explain that I need LESS work than I expected... As most of these guys shoot for the moon and tell you to fix everything every time."

    "I have used this company for 5 years and overall I am pleased. Wonderful telephone customer service. The technicians are knowledgeable, and pleasant. I renewed my annual contract without hesitation."


    We have used JC Flood for all of our plumbing needs since our new home purchase in 2011and have been more than pleased with their service, responsiveness and prices. So when deciding to upgrade our master bathroom, they were the only company we considered. JC Flood transformed our bathroom from drab and outdated to bright and modern. We couldn't be happier...thanks JC Flood!

    I wanted to express in writing my appreciation for the thorough review provided today by Raul on the two A/C systems I have under contract with you. He was clearly comprehensive in his check-up on my older (upstairs) unit and fully explained his recommendations to me. On one issue in particular, he pointed out that my compressor on that unit was not level and the problem that could cause. He then leveled the unit saving me that work. I found Raul to be polite, considerate and, most importantly, thorough in his servicing of my A/C systems. It’s service such as this that keeps me as a John C. Flood contract customer. Thank you.

    "I called John C. Flood around 9 o'clock am and the plumber was at my house 2 hours later. He was very professional and knowledgeable. He diagnosed the problem, gave me a price and made the necessary repairs. I was extremely pleased with my overall experience with the company and will definitely use them in the future."

    "Some quick feedback based on another winning visit from Dale this morning: not only do I dig the "heads up" e-mail including the name and pic of the technician scheduled to come out but the new tablet-based invoice stuff is very cool! Well done! Thank you."

    Joe G.

    "I’ve had a very good experience with them. They’ve serviced my AC and boiler. The boiler required some repairs and they were able to come out quickly and get my heat back on. Jeff was a huge help."
