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 Ashburn
Seven in ten Ashburn homes went up since 2000, Brambleton, Broadlands and One Loudoun included, and only about two in a hundred before 1980. The old-pipe stories, galvanized steel and pinholed copper, mostly belong to other towns. Here a leak is usually a PEX fitting, a compression joint under a vanity, a hose bib that never got drained, or a toilet or washing machine supply line that has simply given out.
Loudoun Water draws a clear line, so you know who to call. It maintains the public main and the connection out to your meter, and repairs a leak there itself. The building service pipe and the plumbing inside your property are the owner’s. Water welling up at the meter box or in the street is theirs. A soft, wet strip of lawn running from the meter toward your foundation is on your side, and that’s the one we dig.
The part most owners forget is the pressure regulator. Loudoun Water’s rules put it on the customer’s side, and its own guide says most houses built after 1972 have one, a bell-shaped valve near where the line comes through the foundation. When it wears out, pressure creeps up, and the weakest fitting in the house lets go first. A hissing sound at night, or a water bill that climbs with no change in habits, is the tell.
Townhouses are 38 percent of Ashburn homes and condos another 19 percent, so a stain on a shared wall is common. Whether it’s your pipe or the association’s depends on where it runs: a line inside your unit is yours, a riser or main feeding several units usually isn’t. We trace it before anyone cuts drywall, and say which it is. One more thing Loudoun Water itself notes: chloramine can wear out rubber gaskets and toilet flappers faster, so a running toilet is worth a look before anyone blames a pipe.

What you’d notice
In a house built in the last 20 years that’s usually a supply fitting or a tub drain connection above the ceiling, not a rotted pipe. Close the stop valves under the upstairs fixtures one at a time. If the stain stops growing, you’ve found the room.
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.
A bill that’s a third higher with nobody new in the house is often a running toilet, and sometimes a pipe. The meter test above sorts out which in a few minutes.

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
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 fitting that keeps failing in a newer house is often pressure, not workmanship. Whoever fixes the leak should put a gauge on a hose bib and tell you the number. Swapping the part without checking the regulator just sets up the next call.
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.

Technician did a leak test, confirmed there weren’t any large leaks… and topped off the refrigerant. Better than the advice we got from other companies.
Questions
If it’s on their side, yes: the main and the connection out to the meter. Everything past the meter to the house is the owner’s. Don’t open the meter box yourself, because Loudoun Water warns that can damage the meter and bring fines. Look at the pooling instead and call the right party.
Shut the stops under the upstairs fixtures and watch the stain. If it stops spreading, it’s a supply line. If it keeps going, run the shower and watch, since drain leaks only show while water is going down. Either way, call before cutting the drywall. A small access hole beats a big one.
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.
