Half of Virginia's Homes Were Built Before 1985 — and Its Water Systems Are Showing It

Virginia's housing stock is old: the median owner-occupied home is 38 years old, per Virginia REALTORS research — meaning half the homes in the Commonwealth were built before roughly 1985, and the plumbing inside many of them dates to the original construction. Galvanized supply lines in pre-1960 urban stock, cast iron drains before 1975, and polybutylene from the massive Northern Virginia and Richmond build-out of the 1980s all remain in service across the state.

January 2025 showed what aging water infrastructure looks like when it breaks. A winter storm knocked out Richmond's water treatment plant, and hundreds of thousands of residents across five localities spent six days under boil-water advisories while the state health department documented twelve significant deficiencies at the plant. The lesson for homeowners runs deeper than one city's plant: the same age-and-freeze forces work on the pipes inside your walls, and everything on your side of the meter is your responsibility.

When something gives, the connection matters. One call to this free referral line matches you with a vetted, licensed Virginia plumber — from NoVa townhouses to Tidewater ranches.

Common Plumbing Issues in Virginia Homes

• Freeze-burst pipes — Virginia winters are cold enough to burst pipes statewide, with frost lines running 18 inches in most of the state and two feet in Northern Virginia and the mountains. The same January storms that stressed Richmond's plant froze residential lines across the Commonwealth.
• Polybutylene and aging copper — PB pipe from 1978–1995 suburbs and pinhole-prone copper in parts of Northern Virginia both drive repipe decisions; galvanized lines in Richmond, Norfolk, and Roanoke's older neighborhoods corrode shut from the inside.
• Expansive "marine clay" soils — Virginia's geology division documents shrink-swell clays across the Coastal Plain and the basins near Richmond, Culpeper, and Danville; Fairfax County publishes a homeowner guide to marine clay for good reason. Moving clay stresses buried service lines and under-slab plumbing.
• Karst country hard water — the Shenandoah Valley sits on limestone karst: sinkhole-prone ground and some of the state's hardest water (Stephens City measures over 300 ppm), a double burden for buried lines and water heaters.
• Tidal flooding in Hampton Roads — Norfolk faces the fastest sea-level rise on the East Coast per Virginia Institute of Marine Science monitoring, compounded by land subsidence. Recurrent flooding means backflow risk, wet crawl spaces, and water heaters in harm's way.

What the Richmond Crisis Means for Your Home

Six days without safe water taught central Virginia two practical lessons. First, municipal failures become household plumbing events: pressure loss lets sediment and air into home lines, water heaters gulp debris when service returns, and post-advisory flushing matters. Second, resilience is partly a homeowner's job — knowing your main shut-off, keeping bottled capacity, and maintaining fixtures that can handle a hard restart.

If your home lost pressure during a municipal event and never quite recovered — weak flow at fixtures, a water heater making new noises, sediment in aerators — a licensed plumber can flush lines, inspect the heater, and check pressure-reducing valves that sometimes fail after system swings.

Virginia Plumbing Licensing

Virginia runs a two-tier system through the Department of Professional and Occupational Regulation. Individual plumbers hold Journeyman or Master Plumber tradesman licenses, earned through documented experience and examination. Plumbing businesses hold contractor licenses in Class C, B, or A tiers based on project size, with a plumbing specialty designation, and must name a licensed master as their qualified individual. Every plumber in our Virginia network holds active licensing at both levels and maintains required insurance coverage.
