Updated October 2026
Winter is the busiest season for DMV plumbers. Freezing nights split pipes in crawlspaces and exterior walls, water heaters work their hardest, and older DC rowhouses with boilers need attention before the cold sets in.
Below are 31 local plumbing companies across Washington, DC, Maryland and Northern Virginia, grouped by state. Many handle water heater and tankless installs, frozen-pipe repair and 24/7 emergency calls. If you want tips on vetting a plumber, read our guide to finding a reliable plumber in the DMV.
How this list was put together: every plumber here is an independent, locally operated business we verified against its own website or a public business record. Nobody paid to be included, and the order within each area is not a ranking. Each name links to the company’s free DMV Business Connect listing with contact details, services and a map.

Winter pipe checklist
- Disconnect garden hoses and shut off the indoor valve to outdoor spigots, then open the spigot to drain it.
- Insulate exposed pipes in crawlspaces, garages, attics and along exterior walls.
- Find your main water shutoff now and make sure it turns. You don’t want to be looking for it during a burst pipe.
- On nights in the teens, let faucets on exterior walls drip and open the cabinet doors under sinks.
- Flush sediment from a tank water heater once a year. If it’s over 10 to 12 years old, start budgeting for a replacement.
- If you’ll be away, keep the heat at 55°F or higher.
How to choose a plumber
- License. Virginia plumbers are licensed through DPOR, Maryland plumbers through the State Board of Master Plumbers, and DC plumbers through the Department of Licensing and Consumer Protection. Ask for the license number and look it up.
- Upfront pricing. Ask whether they charge by the job or by the hour, and whether there’s a trip or diagnostic fee.
- Emergency hours. Ask whether they answer nights and weekends and what the after-hours rate is.
- Permits. Water heater replacements usually need a permit. A good plumber pulls it for you.
