How to hire a plumber in Arlington, VA: a 2026 guide with checklist

Plumbing in Arlington is its own thing. The housing stock ranges from 1920s craftsman bungalows in Lyon Park to 1970s garden-style condos on Columbia Pike to brand-new towers in Rosslyn-Ballston. Older homes have galvanized steel supply lines that corrode internally, lead service lines from the street that water utility replacements have been working through, and original clay-tile sewer laterals that can crack under driveways. Newer condos have shared systems that require board approval for any work that affects risers or common areas. None of this is plumbing you should leave to the lowest bidder on Yelp.

What Arlington-specific plumbing issues look like

Older homes (pre-1960)

Galvanized steel supply lines corrode from the inside out, gradually reducing water pressure and eventually causing low-flow at every fixture. Signs include brown water first thing in the morning, metallic-tasting water, and water pressure that drops when two fixtures run at once. The proper fix is a whole-house repipe with PEX or copper, which is invasive — drywall comes out, floors get patched — but the only permanent fix. Repipe jobs in Arlington typically run $8,000-$15,000 for a 2-bed 1-bath bungalow and up to $25,000 for larger homes.

1950s-1980s homes

Many have original cast iron drain stacks and clay-tile sewer laterals. Cast iron stacks corrode internally and can fail at the joints. Clay-tile laterals crack under driveway weight or root intrusion. Video inspection ($200-$400) is the only way to confirm condition. Spot repairs run $1,000-$3,000; full sewer replacement (trenchless or traditional) runs $5,000-$15,000.

Modern condos and co-ops

Almost all plumbing work inside a condo unit (relocating a fixture, replacing a water heater) is fine for the unit owner to arrange directly. But anything that touches the risers, common stacks, or building shutoffs requires the condo board's approval and often must be done by a contractor the board already approves. Check your building's rules before you call. Some Arlington buildings (especially along the Rosslyn-Ballston Metro corridor) require proof of insurance, COI naming the building, and use of specific suppliers.

Permit requirements

Arlington County requires permits for:

• Water heater replacement (must be done by licensed plumber; Arlington inspects the work)
• Any work that involves opening walls
• Gas line work (must be done by licensed gas fitter)
• Sewer line work beyond the cleanout

Any plumber who says "no permit needed" for water heater work is skipping required steps. Always confirm the permit will be pulled before work starts.

Where plumbers charge more in Arlington

Most Arlington service-area pricing is fair and competitive with the rest of Northern Virginia. However, expect surcharges for:

• After-hours emergency calls (typical 1.5x-2x rates after 6pm, weekends, holidays)
• Saturday appointments (some plumbers charge a small surcharge)
• Tight alley or shared-driveway access (especially in Lyon Park, Ashton Heights, Ballston) — equipment staging is harder
• Historic-district permits in Lyon Park, Bellevue Forest, Cherrydale — extra paperwork, sometimes longer approval times
• High-rise work in Rosslyn-Ballston — service elevator scheduling, contractor badges, COI naming the building

How to vet an Arlington plumber

1. Virginia DPOR license. Search at dpor.virginia.gov by plumber name or license number. License must be active and not expired.
2. Arlington County business license. The county requires plumbers doing business in Arlington to hold an Arlington Business License. Check the county license database or ask the plumber for their Arlington BL number.
3. Insurance. General liability ($1M minimum) and workers' comp. Request a Certificate of Insurance (COI) before any work starts.
4. Tenure. Plumbing businesses that have operated in Arlington for 5+ years are generally safer than recent additions. Verify via the SCC search at cis.scc.virginia.gov.
5. Specialization in Arlington plumbing stock — repiping older homes, sewer lateral replacement, condo board work. Generic "we do everything" plumbers often have less experience with Arlington's specific housing types.
6. Written estimates. Verbal quotes are red flags. The estimate should specify parts, labor, permit fees, and timeline.
7. Warranty terms in writing. At minimum 1-year parts and labor.

What a reasonable Arlington plumbing quote looks like

If a quote is way under these ranges, ask what's excluded. If a quote is way over, get a second opinion.

Red flags to avoid

• "Free estimate" if you don't book. Some plumbers charge for the estimate if you don't proceed. Ask up front.
• Demanding full payment upfront. Reasonable plumbers ask for a deposit on parts only, with balance due on completion. Reputable firms might ask for 10-30% upfront on large jobs (whole-house repipe, sewer replacement).
• Door-to-door canvassing ("we just finished a job in your neighborhood"). Often a sign of high-pressure sales.
• Cash-only discounts. Insist on a paper trail.
• "Permits are your responsibility." The contractor pulls permits and arranges inspections. Full stop.
• Adding "surprise" line items mid-job. Any additional work beyond the original scope should be approved in writing before being performed.

The right way to ask for multiple Arlington plumbing quotes

1. Send the same job description to 3 different plumbers. Same job, same details, same photos.
2. Ask each for a written estimate with parts / labor / permit / warranty clearly separated.
3. Ask each for their DPOR license number and Arlington Business License number.
4. Ask each for a start date.
5. Compare not just total price but the scope items — sometimes the cheapest quote skips the permit or warranty.

When to call an Arlington plumber today

• Active leak. Stop using the fixture, shut off the local stop valve if accessible, call.
• No water anywhere in the house. Could be a frozen/burst pipe (rare in Arlington but happens) or a water main issue; check neighbors first.
• Sewage backup. Stop running any water, don't flush toilets, call emergency service.
• Gas smell — call the gas company first (Washington Gas 1-844-927-4427), then a plumber for any gas-line repair.
