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 Alexandria
More than half of Alexandria’s owner homes are apartments or condos, and another fifth are townhouses. That changes how a leak gets solved. In a building, the water that stains your ceiling often starts in the unit above, or in a riser inside the wall that belongs to the association, and the pipes after your shutoff valve belong to you. Before you call anybody, ask your management office who fixes what. If the answer is you, we’ll take it from there.
Water service in the City comes from Virginia American Water, so a leak in the street or at the meter is theirs to hear about. The sewer is a separate matter, and in Old Town, where the combined sewer dates to the 1800s, a wet basement floor is as likely to be a drain as a supply line. A supply leak runs all the time and a drain only shows when someone uses water upstairs. That one test tells us which pipe to chase.
Six in ten homes in the City went up before 1980, and the rowhouses of Old Town, Parker-Gray and Del Ray have usually been patched many times. Expect galvanized steel in a stretch someone never replaced, copper joined to it, and a few brass fittings that have been on the wall since before any of us were born. A leak in a rowhouse wall usually means we open one small section and find out how far the old pipe goes.
Out toward Kingstowne and Franconia, the Fairfax County side of Alexandria’s mail, it’s a different house. About two thirds of Franconia’s homes and nearly three quarters of Kingstowne’s were built between 1980 and 1999, and half of them are townhouses. That’s the stretch of years for gray polybutylene supply pipe, and a drip at a crimped fitting near the water heater is how it usually announces itself. Huntington is the other end: older high-rise and garden buildings, where the risers matter most.
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 |
|---|---|---|---|---|
| City of Alexandria | 1970 | condo and apartment buildings, about 5 in 10 | gas, about 6 in 10 | Condo buildings: association risers, your own lines inside the unit. |
| Rose Hill | 1969 | single-family houses, about 7 in 10 | gas, about 7 in 10 | Copper supply, old enough for pinholes. |
| Franconia | 1986 | townhouses, about 5 in 10 | electricity, about 6 in 10 | The polybutylene years: check the supply pipe at the fittings. |
| Fort Hunt | 1963 | single-family houses, nearly all | gas, about 8 in 10 | Galvanized supply on the oldest streets; leaks at the fittings. |
| Kingstowne | 1994 | townhouses, about 5 in 10 | gas, about 7 in 10 | The polybutylene years: check the supply pipe at the fittings. |
| Woodlawn | 1976 | townhouses, about 4 in 10 | electricity, about 6 in 10 | Copper supply, old enough for pinholes. |
| Lincolnia | 1982 | single-family houses, about 4 in 10 | gas, about 7 in 10 | The polybutylene years: check the supply pipe at the fittings. |
| Mount Vernon | 1967 | single-family houses, about 7 in 10 | gas, about 7 in 10 | Copper supply, old enough for pinholes. |

What you’d notice
If the stain is under a neighbor’s bathroom, the leak may be theirs, or the building’s, and your management office has to see it before anyone cuts anything. Photograph it, note when it started and whether it grows after the upstairs unit showers.
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
In the City, who owns the sewer lateral depends on when it went in: on laterals laid before July 1, 1955 the owner has the stretch from the curb to the house. 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.
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.
In a condo or rowhouse the answer decides who pays. A plumber who knows Alexandria asks where your shutoff is, what the association owns, and then tells you which side of the line the leak is on before you hear a price.
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
Call the building first if the water is coming from the unit above or from a riser in a shared wall. Shut off your own water if the drip is yours, then call us. If it’s inside your unit’s walls, below your shutoff, it’s your repair and we can come see it.
If it’s polybutylene, it fails most at the fittings, and those houses are now thirty years old or more. One leak doesn’t mean the whole house has to be redone today, but have the other joints looked at while a plumber is there, and ask for the price in writing.
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.
