How much does a plumber cost in Washington?
DC plumbers charge $69-$115 per hour for scheduled work, with an average of $92/hr. Emergency calls (nights, weekends, holidays) run $130-$185/hr plus a $150-$225 trip charge. Neighborhood matters: Georgetown, Capitol Hill, and Dupont sit at the top of the range because of pre-1900 row houses with lead supply lines, cast-iron drain stacks, and HPRB review on any visible exterior work. Upper NW single-family neighborhoods and modern Navy Yard buildings sit at the bottom.
The Bureau of Labor Statistics reports the median hourly wage for plumbers in the Washington-Arlington-Alexandria metro at $45.90. The gap between that and the $92/hr you actually pay is real and explainable, and the rest of this article walks through where every dollar goes, what permits and DC Water coordination you actually need, and what to ask when comparing quotes.
DC Plumber Rates by Neighborhood
The District is not one plumbing market. A pre-1900 Georgetown row house with a lead service line and an HPRB-protected facade is a different job than a 2015 Navy Yard condo on copper and PEX, and the price reflects that. The full per-neighborhood breakdown sits at the top of this page; this section explains the why behind the numbers.
The premium for Georgetown, Capitol Hill, and Dupont is not arbitrary. A typical call in those neighborhoods includes 30-45 minutes of parking and travel on narrow row-house streets, a building check-in if the unit sits in a condo or co-op, careful work in plaster walls where modern PVC cannot be surface-mounted, and (for any exterior change) an HPRB filing the contractor has to scope at quote time. Upper NW single-family homes and modern Navy Yard condos skip most of that.
Comparable cities for cross-reference:
- New York plumber costs — $66-$110/hr
- Boston plumber costs — $60-$100/hr
- Philadelphia plumber costs — $50-$90/hr
- Atlanta plumber costs — $55-$95/hr
DC sits roughly 15-25% above the Mid-Atlantic metro average, mostly explained by historic-district overhead, the share of pre-war row housing stock with cast-iron and galvanized plumbing, and the federal-city dynamic of embassy and official-residence work that pulls licensed Master Plumbers into security-cleared schedules.
DC Plumber Pricing by Building Type
Neighborhood is one axis. Building type is the other, and it often matters more than the address. A 1910 Capitol Hill row house with original cast-iron drain stacks, galvanized supply, and a lead service line costs noticeably more to work on than a 2018 NoMa condo two miles away, because the work itself is slower and parts are non-standard.
| Building type | Hourly rate | Why the price moves |
|---|---|---|
| Pre-1940 row house (Georgetown, Capitol Hill, Adams Morgan, Logan Circle) | $100-$145 | Lead service lines, cast-iron drain stacks, galvanized supply, HPRB review on exterior work, narrow stairwells |
| Pre-war condo / apartment (Dupont, Foggy Bottom) | $90-$130 | Building board coordination, freight-elevator scheduling, lead supply lines, after-hours rules |
| Mid-century NW apartment building (1950s-1980s) | $80-$120 | Mostly copper supply, simpler valves, fewer surprises during diagnosis |
| Modern condo / new construction (post-2010, Navy Yard / NoMa / Wharf) | $75-$110 | PEX or copper, code-current fittings, standardized fixture spacing |
| Single-family home (Upper NW, Cleveland Park, Spring Valley) | $70-$105 | Basement access, suburban-style plumbing, no co-op or doorman coordination |
The pre-war premium is real and not arbitrary. Cast-iron stack repair requires specialty cutters and a working knowledge of how to splice modern PVC into 1910s cast iron without compromising the drain pitch. Galvanized supply lines that have been in the ground for 80-100 years are usually scaled half-shut from the inside, and partial replacement rarely makes economic sense once you open the wall. If your home is pre-1940, ask whether the plumber has done cast-iron stack and galvanized supply replacement in the last 12 months.
What Your Billed Hour Actually Covers
The $45.90 BLS wage is take-home pay for the plumber, not what the customer pays. The customer rate of $69-$115/hr covers everything the business needs to legally operate in the District.
Roughly: 50% labor, 12% commercial liability and bonding insurance ($14,000-$22,000/yr per crew in DC because plumbing carries higher water-damage claim rates than most trades), 11% vehicle and specialty tools (cast-iron snap cutter, drain camera, pipe-threading rig for galvanized), 10% DC-specific licensing and overhead (DCRA/DLCP Master Plumber and Gas Fitter license renewals, residential parking permits, dispatch), and 17% contractor profit margin. Strip any of those out and the business cannot stay open.
This is why the cheapest quote is not always the right one. A plumber bidding $45/hr is either operating without insurance (your homeowner’s policy will not cover the resulting water damage), without a DC-issued Master Plumber license (DOB will not sign off on the work and resale becomes a problem), or losing money and about to disappear mid-project.
DC Plumber Permits and What They Cost
DC’s Department of Buildings (DOB) and the Department of Licensing and Consumer Protection (DLCP, formerly part of DCRA) sit on top of every meaningful plumbing job. DC Water coordinates any work that touches service lines, meters, or the sewer main. Skipping the permit step is the most common way DC homeowners turn a $1,500 job into a $6,000 problem at resale.
| Work | Permit | Typical cost | Lead time |
|---|---|---|---|
| Faucet, fixture, or simple repair | None required | $0 | Same day |
| Water heater replacement (tank, like-for-like) | DOB plumbing permit | $75-$200 | 5-10 business days |
| Tankless water heater conversion | DOB plumbing + Gas Fitter permit | $200-$400 | 2-3 weeks |
| Bathroom or kitchen renovation | DOB plumbing permit | $200-$500 | 2-4 weeks |
| Service-line or sewer-line replacement | DOB plumbing + DC Water coordination + DOB street-cut if applicable | $400-$1,200 | 3-8 weeks |
| Exterior work in a historic district | DOB plumbing + HPRB review | $300-$800 | 4-16 weeks |
Your plumber files the DOB permit on your behalf and the fee gets added to the invoice. DC Water coordination is handled the same way for any service-line or meter work. HPRB review for visible exterior work (a new cleanout cap on a Georgetown facade, an exterior tankless mount on a Capitol Hill rear wall) adds 4-8 weeks for staff review or 8-16 weeks if the project escalates to a full hearing. For larger renovations crossing multiple trades, expect to coordinate the plumbing permit with a DC general contractor who handles the full permit package as one filing.
Common Plumber Job Pricing in DC
These are typical all-in prices, including labor, parts, DC-specific permit fees where applicable, and 1-year workmanship warranty. Historic-district row houses sit at the high end of each range; Upper NW single-family and Navy Yard modern construction sit at the low end.
| Job | Total cost | Labor hours | Notes |
|---|---|---|---|
| Toilet replacement | $400-$800 | 2-3 | Includes $50-$100 disposal; pre-war row houses with old rough-in measurements add $100-$200 |
| Faucet replacement (kitchen or bath) | $275-$525 | 1.5-2.5 | Older buildings often need new shutoff valves (+$100-$200) |
| Water heater (40-gal gas, tank, like-for-like) | $1,600-$2,800 | 4-6 | DOB permit $75-$200, disposal $100-$200, possible Washington Gas coordination |
| Tankless water heater conversion | $3,500-$6,500 | 6-10 | Gas Fitter permit, larger gas line common in pre-war row houses, exterior venting may trigger HPRB |
| Drain unclogging (snake, single fixture) | $200-$400 | 1-2 | Camera inspection +$200-$400 if recurring |
| Main sewer line clear | $450-$950 | 2-4 | Tree-root removal in Capitol Hill and Mount Pleasant row houses common |
| Lead service line replacement (private side, outside program) | $4,000-$9,000 | 12-24 | DOB permit + DC Water coordination + street-cut restoration; free under Lead Free DC if eligible |
| Cast-iron drain stack section replacement | $2,000-$4,800 | 8-16 | Specialty job; pre-war Georgetown, Capitol Hill, Adams Morgan |
| Burst-pipe emergency repair | $400-$1,200 | 2-4 | + emergency surcharge if after-hours; drywall and plaster damage adds significantly |
Lead service line replacement deserves its own callout. Many DC row houses built before 1940 still have lead on the private side, the public side, or both. DC Water’s Lead Free DC program replaces eligible service lines at no homeowner cost, including the private portion. Outside that program, full replacement runs $4,000-$9,000 depending on street-cut restoration and whether the meter pit needs work. If your home is pre-1940 and you have not confirmed your service-line material, check with DC Water before any kitchen or bath renovation that depends on flow rate.
How to Get and Compare DC Plumber Quotes
Three things separate a useful quote from a useless one in DC, and they all come down to specificity.
-
Tell the plumber the building age, type, and neighborhood. “1910 Capitol Hill row house, lead service line, galvanized supply on the second floor, gas water heater in the basement, HPRB district” gets a different number than “2018 Navy Yard condo, 4th floor, freight elevator.” Plumbers price the job partly off access logistics and historic-review exposure, so generic “I need a water heater” estimates are worth less than a more detailed brief.
-
Ask for an itemized written estimate that breaks out labor hours, materials with brand names (Rheem, A.O. Smith, Bradford White for water heaters; Kohler, Toto, American Standard for fixtures), DOB permit fees, DC Water coordination, and any HPRB exposure. Verbal estimates are not enforceable in DC and tend to grow on the day. Reputable DC plumbing companies email itemized PDFs within 24-48 hours of the site visit. If the contractor will not put it in writing, walk.
-
Verify the license and insurance before you book. Pull the Master Plumber (and Gas Fitter, if relevant) license number from the DC DCRA / DLCP public license search and request a current Certificate of Insurance showing $1M general liability minimum and DC workers’ compensation. Both checks take five minutes and rule out 90% of the contractors who later become problems.
How We Calculated These Prices
The DC plumber hourly rate of $69-$115 starts with the BLS Occupational Employment and Wage Statistics mean hourly wage for plumbers, pipefitters, and steamfitters in the Washington-Arlington-Alexandria metropolitan statistical area: $45.90 as of May 2024. We apply a 1.5x-2.5x consumer multiplier covering business overhead, insurance, licensing, vehicle costs, employer-paid taxes, and contractor profit margin, calibrated against current market quotes from DC-licensed Master Plumbers.
Neighborhood-level adjustments reflect access logistics (parking, freight-elevator scheduling, building board check-in), building-stock differences (lead service lines, cast-iron and galvanized vs. modern PEX and copper), and HPRB / historic-district administrative overhead. The full formula and source list lives on our methodology page.
Other DC Service Costs You Might Need
Plumbing rarely happens in isolation. A kitchen or bath renovation typically pulls in 3-4 trades, and water heater swaps frequently coordinate with HVAC and electrical load planning. Getting quotes from all of them at the same time is faster than serial calls.
- DC electrician costs — for any plumbing work that adds a circuit (disposal, dishwasher, tankless water heater)
- DC HVAC technician costs — for boiler, steam, or combi-system work that touches gas and water lines
- DC carpenter costs — for vanity, tile-prep, and plaster patching after a wall opening
- DC handyman costs — for sub-Master-Plumber-license tasks like fixture swaps and supply-line replacement
- DC general contractor costs — when the project crosses 3+ trades and needs a single DOB filing
