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 Warrenton
The Town of Warrenton makes its own water, from the Warrenton and Airlie Reservoirs and three wells, so inside the limits there is a Town meter and a clear line between its pipe and yours. The Town looks after its side, and it will locate it. The line from the meter to the house is the owner’s, and finding which stretch is leaking is the plumber’s job. If the leak runs from the street to the meter, call the Town. If it’s between the meter and the house, call us.
One thing to know before you dig anywhere: replacing a water lateral from the street takes a Town permit, with the work built to the Town’s Public Facilities Manual. Ask us about it at the estimate, so the permit is sorted before the trench is open.
The Town flushes its hydrants every spring and fall, and its own advice for rusty or brownish water afterward is to run the cold tap until it clears. So if the water turns brown in April or October, that is likely the flush, not your pipes. If it stays brown after the tap has run and the neighbors’ water is clear, the cause is probably inside your house, and with homes built before 1960 making up more than a quarter of the town, that usually means galvanized steel rusting from within.
Housing here is not one thing. Just over half of the town’s homes are detached; about one in five is a townhouse, one in eight is a small apartment building, and one in nine a condo or apartment. In the Historic District around Main Street and in the older blocks by Broadview Avenue and Alwington Boulevard the pipes are the oldest. In Leeds Square and the townhouse rows, a stain on your wall may come from next door, so we find the source before anyone gets the bill. Out in New Baltimore and Vint Hill, FCWSA runs the water, under a different set of rules, and on private wells there is no meter at all.
Neighborhood by neighborhood
Census figures for each place, and the supply pipe that usually goes with houses that age. Median year built and heat count owner-occupied homes only.
| Place | Median home built | Most homes are | Heated with | The supply pipe you usually find |
|---|---|---|---|---|
| New Baltimore | 1999 | single-family houses, nearly all | gas, about 5 in 10 | Copper or PEX supply; fittings and hose bibs go first. |
| Warrenton | 1993 | single-family houses, about 5 in 10 | gas, about 6 in 10 | The polybutylene years: check the supply pipe at the fittings. |
By the numbers
From the Census Bureau’s 2020 to 2024 survey. Median year built and heat count owner-occupied homes only.
Inside the town limits, a little over 4 of the roughly 110 square miles the two Warrenton ZIP codes cover: the Historic District around Main Street, Leeds Square, and the streets off Broadview Avenue and Alwington Boulevard.
New Baltimore only. It’s the one Census place on the county side with mostly Warrenton mail, so the farms and lots beyond it aren’t in these figures.
What you’d notice
If the neighbors’ water is clear and yours is brown, the cause is likely on your side. Rust from galvanized pipe tends to show first thing in the morning, then clears after a minute of running. A pinhole in copper rarely changes the color, but it will move the meter.
Galvanized steel pipe rusts from the inside, and the threads at each fitting go first. Brown water after the tap sits, or a damp drip at a joint in the basement, usually means more of that pipe is close behind.
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
On Town sewer the owner keeps up the line from the cleanout at the curb, or the property line where there’s no cleanout, to the house, and on Town water the line from the meter to the house. The Town locates its own side; finding the house side is your plumber’s job. Source.
On Town water, the Town sends questions about water pressure to its Water Treatment Plant. Source.
On FCWSA sewer, the service line from the main to the property line and the lateral from there to the house are the customer’s to clear. FCWSA clears its mains and fixes a service line under a public street, and it doesn’t reimburse a plumber. Source.
On FCWSA water (Bealeton, Catlett, Marshall, New Baltimore, Vint Hill and its other systems), FCWSA says it can’t guarantee uniform pressure, and that over 80 psi the customer should install a pressure regulating valve at their own expense. Homes on private wells aren’t covered by this. 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.
Ask. In Warrenton the Town’s pipe ends at the meter and the owner’s starts there, and a plumber who checks the meter first can tell you whether the Town should be involved, which can save you a repair bill that isn’t yours.
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
For a lateral from the street, yes, the Town issues it. A repair to a pipe inside the house doesn’t need one. We’ll tell you at the estimate which kind of job you have.
We can’t say that from the pipe alone. The Town’s 2025 water report is public, and it is the place to look at what is in the water. What we can say is that copper from the 1970s and earlier is old enough to pinhole whatever the water is. If you’ve had two, call us before the third.
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.
