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 McLean
Few places in our service area put a 1950s rambler and a tower finished in the last few years inside the same two ZIP codes. About one owner home in eight in 22101 and 22102 went up before 1960. Nearly a third have gone up since 2000. So the first thing we ask on the phone is what year the house is, because that decides whether we’re hunting a galvanized elbow behind a plaster wall or a loose fitting on plastic tubing that’s barely old enough to vote.
The other thing that sets McLean apart is how many people here don’t own the pipe that’s leaking. Around four in ten homes in these ZIPs are apartments or condos. In a tower, the vertical lines that run through your kitchen wall to the unit above and below usually belong to the association, and the branch that comes off them at your valve usually belongs to you. Where that line falls is spelled out in your building’s documents, so read them or call the front desk before anyone cuts drywall. We’ll tell you which side of the valve a leak is on, and that settles who calls whom.
Detached houses are about half the homes here, and the older ones are the most interesting to open up. McLean ramblers and split-levels from the postwar years have often had a bathroom added, a kitchen opened up, or a basement finished, so one house can hold galvanized, copper and plastic all joined together. The leaks tend to sit at those joins. Tell us what’s been renovated and when, and we start there rather than at the water heater.
And some McLean houses are on wells, even though most of the town is on Fairfax Water. They crowd toward the Great Falls side, along roads like Old Dominion Drive, Towlston Road and Georgetown Pike. If that’s you, a pump that keeps running is your first warning, since no meter is spinning. Our pipe repair page covers how we price the work.
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 |
|---|---|---|---|---|
| McLean | 1977 | single-family houses, about 8 in 10 | gas, about 7 in 10 | Copper supply, old enough for pinholes. |
| Tysons | 1985 | condo and apartment buildings, about 7 in 10 | electricity, about 5 in 10 | Condo buildings: association risers, your own lines inside the unit. |
By the numbers
From the Census Bureau’s 2020 to 2024 survey. Median year built and heat count owner-occupied homes only.

What you’d notice
If the stain is under a bathroom or kitchen above you, the leak may be in that unit, in a shared riser, or in yours. Take photos, shut your own unit’s valve if you can, and tell the front desk. We can tell you from your side whether your lines are the source.
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.
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.
We’ll show you where the leak is and which side of your unit’s shutoff it sits on. The association’s documents decide who pays for what, but knowing the location is what makes that conversation short.
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
Not by itself. Mixed metals are normal in a house that’s been renovated twice. The trouble spot is where steel meets copper without a proper dielectric fitting, because that joint corrodes and weeps. We check those first.
The work is the same, the permission isn’t. Buildings often want notice before a unit’s water is shut off, and some need a licensed plumber on their list. Tell us the building and we’ll plan around it.
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.
