Repiping & Pipe Replacement in Vienna: the local picture

This is polybutylene country — gray PB pipe went into a huge share of homes built 1978–1995 across Fairfax County. It fails without warning and insurers know it. A PEX repipe typically takes 2–3 days and permanently retires the risk.

Polybutylene from the '80s, galvanized from the '50s, or copper with pinhole leaks — a whole-home repipe in modern PEX or copper ends the leak-repair cycle for good.

Local pipe report

What's under Vienna's homes

Ground & soilHeavy piedmont clay that swells when wet and shrinks in drought — hard on buried sewer joints and slab-side supply lines.
WaterFairfax water / arlington des public water from the potomac and occoquan — moderately hard; expect scale in water heaters after 8–10 years.
Housing stock1950s–70s ramblers and colonials with original galvanized or copper, plus a huge band of 1978–1995 homes plumbed in polybutylene.
Freeze riskA handful of hard-freeze snaps each winter; pipes in garage ceilings, bonus rooms and hose bibs burst during polar-vortex weeks.
Worth knowing in Vienna: Northern Virginia sits in the national hot zone for polybutylene (PB) piping — gray plastic supply lines installed roughly 1978–1995 that fail without warning. If your home was built in that window, a repipe assessment is the single smartest plumbing call you can make.

Straight answers for Vienna

How do I know if my home has polybutylene pipes?

Check exposed pipe near the water heater or under sinks: polybutylene is usually gray (sometimes blue or black), flexible plastic, often stamped 'PB2110.' Homes built 1978–1995 in Fairfax and Arlington counties are prime candidates. If you find it, don't panic — but do get a repipe assessment, because PB fails without warning and many insurers surcharge or decline it.

How disruptive is a whole-home repipe?

Less than people fear. A typical single-family repipe runs 2–3 days; water is on each evening. PEX routes through existing cavities with minimal openings, and drywall repair is part of the scope, not your problem afterward.

PEX or copper for the repipe?

PEX for most Virginia homes: freeze-tolerant, corrosion-proof, quieter, and more affordable. Copper still suits specific situations and preferences. What matters most is the installer and the fittings — we'll walk you through both honestly.
