Most repairs are one section of pipe: the split or pinhole cut out and a new piece put in. Where the pipe sits decides most of the price. Exposed in a basement ceiling is the low end; inside a finished wall is higher, and we tell you before the drywall comes open.
With Comfort+ membership, any repair is 15% off, and every year includes a plumbing safety inspection that looks at the supply pipe you can see.
What’s different in Great Falls
Many Great Falls houses draw from a private well, and a well has no meter. That takes away the first alarm other towns get, the bill that suddenly doubles. Here the warning is the pump. If it starts when nobody is using water, or the needle on the tank gauge drifts down overnight, water is escaping somewhere between the tank and a fixture, and the pump is paying for it in starts. The county’s own map can’t say which houses have a main, so we ask on the phone: well, or Fairfax Water?
The houses are big. The middle Great Falls house runs about 3,700 square feet with four full bathrooms, and nine in ten have a full basement, many with a bath or a bedroom finished in it. That’s a lot of supply line, and a lot of drywall between you and a slow leak. Pipes in a basement ceiling that was finished after the plumbing went in are the ones we cut open most often.
Great Falls has real old houses mixed in. About one in sixteen predates 1960, and the county’s tax records list some from the 1700s. Those are often repiped in pieces over the years, copper joined to galvanized, so a leak at a transition fitting is common. The rest are mostly 1970s and 80s, in places like Lexington Estates and Hickory Creek, which puts them in the pinhole and polybutylene years.
Lots here are often two and five acres, so the buried line from the well to the house can be long. When it leaks you won’t see a puddle. You’ll see a patch of lawn that stays green in a dry August, or a pump that runs and a tank that never fills. We trace it from the tank out, and tell you which stretch of pipe it’s in.
By the numbers
From the Census Bureau’s 2020 to 2024 survey. Median year built and heat count owner-occupied homes only.
What you’d notice
Turn off every fixture and watch the needle for a few minutes. If it falls and the pump kicks on, water is leaving the system. Close the shutoffs for half the house at a time and we narrow it down before anything gets cut.
Polybutylene, often stamped PB, went into houses from about 1978 to 1995. It tends to fail at the fittings without much warning, so a drip at one joint is a reason to look at the rest.
A brown ring under a bathroom, or a soft spot in the drywall, is water that’s been finding its way down for a while. A supply pipe leaks all the time; a drain only leaks when somebody runs water upstairs, and that difference tells us where to look first.
Turn everything off and watch the water meter for ten minutes. If the dial or the little leak indicator still moves, water is going somewhere, inside a wall, under a slab or out in the yard.

Before the first hard freeze
A pipe usually bursts in the hours after a cold snap, when the ice inside it thaws and the split starts to run. Five things to do before it gets that cold, then call us if something already looks wrong.
Disconnect every garden hose. A hose left on traps water in the spigot, and that’s the most common split we see. If the spigot has a shutoff inside the house, close it and open the outside tap to drain it.
A kitchen or bathroom sink on an outside wall gets the coldest air in the house. On the coldest nights, open the cabinet doors so room heat reaches the pipes, and let that tap drip.
Close crawl space vents and the garage door for the winter. Pipes that run through a crawl space, a garage ceiling or an unheated room over the garage are the ones that freeze first.
Find it now, before you need it: usually where the water line comes through the basement or crawl space wall, near the meter or the water heater. Make sure it turns. When a pipe bursts, that valve is the difference between a mop and a contractor.
Keep the thermostat at 55 or higher while you’re gone, and ask someone to look in if a cold snap comes. A frozen pipe that thaws with nobody home runs for days.
Find a pipe that’s frozen, or water where it shouldn’t be? Shut the main off and call us at (703) 997-9757. A diagnosis visit is $49, or $250 after hours, and you get the repair price before we cut into anything.
Your pipes, your paperwork
In Fairfax County the homeowner owns the whole sewer lateral, from the house to the county main, including the stretch under the street. Replacing it takes a county plumbing permit, plus a VDOT permit under a state road. Source.
Fairfax Water promises 20 psi at the main and no uniform pressure, and the pressure reducing valve on your side of the meter is yours to buy and keep up. Over 80 psi, the Virginia Residential Code calls for one, and an expansion tank with it. Source.
Our Virginia Class A contractor license, 2705192276, is on the side of the van.
Choosing who fixes it
Questions worth asking anybody who comes out, us included.
A pump that short-cycles is often a symptom of a leak, not a bad pump. Replace it without finding the leak and the new one runs the same hours, which wears it out the same way.
Anyone can check on the state’s license lookup. Ours is Virginia Class A contractor license, on every van.
A good leak call starts at the meter and the shutoffs, then narrows it down with pressure and moisture readings. The drywall comes open in one spot, not five.
Every repair on our list has a range, and you hear where yours lands before anything is cut. If someone won’t say until the job is done, keep looking.

The issue was with a leak in the toilet tank that technician repaired . He did a good job.
Questions
Yes, and it’s the one place you can’t see. Look for ground that’s soft, or grass that’s greener than the rest in a dry spell, along the path the pipe takes. We trace it from the pressure tank out, so you know whether it’s the buried stretch or the plumbing inside the house before anyone digs.
The ones with no heat nearby: the pipe where the line enters through the foundation, any run in an unheated garage or crawl space, and the room with the pressure tank if it’s an outbuilding. With no meter pit to freeze, the exposed pipes are the ones that go.
Shut off the main water valve, then turn off the water heater (gas to pilot, or the breaker for electric). Open a faucet at the lowest point of the house to drain what’s left in the pipes. Then call (703) 997-9757: a person answers day or night, and our emergency plumbing team is on 24/7.
A plumbing diagnosis visit is $49, or $250 after hours. Finding a leak you can’t see is $200 to $500, and most water pipe repairs run $450 to $650. You get the number before we start.
