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 Chantilly
Drive from Greenbriar to South Riding and you cross three generations of plumbing. Greenbriar’s typical owner home dates to 1970 and close to six in ten homes there predate 1980. Copper that old is where pinholes start, and a few houses may still have galvanized steel somewhere. The Fairfax side of Chantilly is mostly 1980s and 90s, with a typical owner home from 1987, right in the polybutylene window. Gray plastic with crimped rings near the water heater is what we look for.
South Riding is a different story. The typical owner home dates to 2006, three in four homes went up since 2000, and nearly half are townhouses. The pipe there is PEX or copper and should last. What fails is smaller: a fitting, a hose bib, a regulator that has worn out, and in a townhouse, the question of which wall the water is in.
Your address decides which utility you call. On the Loudoun side, Loudoun Water’s rules make the public main and the connection to the meter its own to repair, and the pipe and plumbing from there to the house the owner’s. Pressure regulators are the customer’s too. On the Fairfax side, Fairfax Water’s rules put the pressure reducing valve on the owner’s side of the meter, which makes it yours.
The mail says Chantilly on both sides of the county line, but a leak at a Loudoun address goes to Loudoun Water and one in Fairfax County goes to Fairfax Water. Not sure which you are? The name at the top of your water bill settles it. Then check which side of the meter the wet ground is on before you call anyone.
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 |
|---|---|---|---|---|
| South Riding | 2006 | single-family houses, about 5 in 10 | gas, about 8 in 10 | Copper or PEX supply; fittings and hose bibs go first. |
| Chantilly | 1987 | single-family houses, about 6 in 10 | gas, about 5 in 10 | The polybutylene years: check the supply pipe at the fittings. |

What you’d notice
Chantilly’s red clay is dense, and water from a buried line often travels along the pipe trench before it comes up. The wet spot can sit well away from the break, so we trace the line before anyone digs.
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.

Choosing who fixes it
Questions worth asking anybody who comes out, us included.
Out here the answer changes who fixes what. A plumber who asks for your street, or a look at the bill, is working out whether the leak is on a part you own.
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.

Arrived within an hour on a Sunday morning and provided great service.
Called SwiftPro around 5 am and their electronic system scheduled an appointment for us same day.
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
Look at the top of your water bill. The company’s name is there. It matters because each one’s rules stop at a different place, and only a leak on your side of the meter is yours to repair.
One pinhole is a repair. Several in a year, or green crust on more than one line, means the copper is thin throughout and it’s worth a real conversation. We’ll show you the pipe, fix what’s leaking, and tell you what we see in the rest.
Often in the wall behind the stairs or the closet under them, where the supply lines drop to the lower level. Tell us the room and which neighbor shares that wall, and we’ll start with the water heater closet and the fittings on that run.
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.
