Toilet Repair & Installation in McLean: the local picture

Older cast-iron flanges in pre-1970 homes rust and break, leaving toilets rocking and wax seals leaking into the ceiling below. We repair flanges properly instead of stacking wax rings — the difference between a fix and a callback.

Constantly running, rocking at the base, phantom flushing, or ready for an efficient new unit — toilet work done right the first time, seal to supply line.

Local pipe report

Know your McLean pipes

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 McLean: 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.

Questions McLean homeowners ask us

Why does my basement need a battery backup sump pump?

Because the storms that flood NoVA basements are the same storms that knock out power. Clay soil sends stormwater straight to your foundation drain, and a finished basement turns a failed pump into a five-figure claim. Battery backup keeps the pit dry through the outage.

My toilet runs constantly — what's it costing me?

A running toilet wastes hundreds of gallons a day — real money on municipal water, and on a well it cycles your pump nonstop and can overload a septic drainfield. It's usually a flapper or fill valve: a fast, cheap fix that pays for itself in weeks.

The toilet rocks slightly — is that serious?

Yes, more than it feels. Rocking breaks the wax seal, letting water seep at the flange every flush — into the subfloor or the ceiling below. Often the flange or its bolts need repair, not just new wax. Fix it before the floor tells you to.
