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 Falls Church
A Falls Church address reaches well past the City limits. Seven Corners, Bailey’s Crossroads and Merrifield are Fairfax County, and the City keeps its own permit counter at City Hall. For a water leak the good news is simple: Fairfax Water has run the City’s system since 2014, so the utility on your bill is the same on both sides of the line. The permit paperwork is not, and we handle whichever office your address needs.
The age of the pipe is the other half. In West Falls Church and Lake Barcroft, nearly half of owner homes predate 1960, and the City’s median owner home is from 1964. Houses that old were plumbed in galvanized steel, which rusts shut from the inside. The first signs are brown water after the tap has sat and a drip at a threaded joint. One leaking joint usually means the next one is on its way, and we show you the pipe so the choice is yours.
Seven Corners and Bailey’s Crossroads are another kind of place altogether: about half the homes at Seven Corners are condos or apartments, and in Bailey’s Crossroads it’s six in ten. In those buildings the question is who owns the pipe. The riser in the wall belongs to the association, the branch past your unit’s shutoff is yours, and a stain on a ceiling can come from either one. Call the front office with a photo before you call anyone to cut a wall.
Pressure is the thing Fairfax Water won’t promise. It stands behind 20 psi at the main and nothing about an even pressure, and the reducing valve that evens it out is the customer’s to buy and maintain. Old galvanized takes high pressure badly, so if the faucets hammer or a fill valve hisses, a gauge on the hose bib reads the pressure in a minute. Pimmit Hills and the 1960s streets around it are copper country, where pinholes are the usual failure.
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.

| Bailey’s Crossroads | 1980 | condo and apartment buildings, about 6 in 10 | electricity, about 5 in 10 | Condo buildings: association risers, your own lines inside the unit. |
| Idylwood | 1975 | condo and apartment buildings, about 4 in 10 | gas, about 5 in 10 | Condo buildings: association risers, your own lines inside the unit. |
| City of Falls Church | 1964 | condo and apartment buildings, about 5 in 10 | gas, about 7 in 10 | Condo buildings: association risers, your own lines inside the unit. |

What you’d notice
If the first draw in the morning is brown and then runs clear, the inside of a galvanized pipe is flaking. Run the tap that’s farthest from the main. If it’s brown at only one fixture, the problem is the run to that fixture.
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.
Old copper fails in pinholes: a fine mist or a green crust on a pipe in the basement ceiling. One pinhole is a repair. Several in a year on the same run is the pipe telling you it’s thinning everywhere.
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.

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
The City of Falls Church says the property owner owns the sewer lateral up to the City’s main and is responsible for keeping it up; Public Works takes no responsibility for the stretch between the house and the main. Source.
Fairfax Water has run the City’s water system since January 3, 2014, and its rules hold inside the City: a minimum of 20 psi at the main in the street, no promise of an even pressure, and a pressure reducing valve that is the customer’s to buy, install and keep up. Source.
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.

Choosing who fixes it
Questions worth asking anybody who comes out, us included.
A plumber who works in Falls Church knows that a 22042 mailing address may be in the County while a Park Avenue address is in the City. Ask which office will issue the permit before you sign.
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.

Questions
Both are Fairfax Water now. Fairfax Water bought the City’s system in 2014, so your bill and your meter are the same on either side of the line. What changes is who issues permits for the repair, and we’ll sort that out for you.
If the stain is under a neighbor’s bathroom or near a riser, that’s the building’s or the neighbor’s to find. If it’s from a pipe inside your own walls past your shutoff, it’s your repair. Take a photo and call the office first, then us.
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.
Ready when you are
Shut off the main, then call, or send the form at the top. You get the price before the work, and if it can wait until morning, we’ll tell you that too.
