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 Annandale
Eight in ten Annandale homes were built before 1980, and in Wakefield it’s nine in ten, almost all of them detached ranches and split levels. Those houses were plumbed in copper, and copper that old stops failing at the joints and starts failing in the pipe wall. A pinhole sprays a fine mist you can’t see until the drywall below turns soft, which is why the first sign is often a stain on a basement ceiling, not a puddle.
Pinholes tend to come in a series. One leak on a run is a repair; two or three in a year on the same run tells us the pipe is thin everywhere along it, and that’s the moment to talk about replacing that run rather than patching it each winter. We cut out the bad section, put in new pipe and show you what the inside of the old piece looked like, so the call is yours.
Pressure plays a part. Fairfax Water promises only 20 psi at the main and no steady figure above it, so pressure on one Annandale street can differ a lot from the next. Anything over 80 psi is hard on old copper, and the pressure reducing valve that holds it down sits on your side of the meter and is yours to keep up. If your faucets hammer when a valve closes, a gauge on the hose bib reads the pressure in a minute.
About a fifth of Annandale’s homes are older than 1960, and in those the supply may still be galvanized steel somewhere, usually in a wall nobody has opened. Woodburn is different again: nearly a third of its homes are apartments and condos, where a leak in the wall between units is a question for the association before it’s a question for us. About three in ten Annandale homes are rented, so we’re often called by a landlord who needs the repair done and a tenant’s schedule worked out.
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 |
|---|---|---|---|---|
| Annandale | 1967 | single-family houses, about 5 in 10 | gas, about 7 in 10 | Copper supply, old enough for pinholes. |
| Wakefield | 1968 | single-family houses, nearly all | gas, about 8 in 10 | Copper supply, old enough for pinholes. |
| Woodburn | 1968 | single-family houses, about 4 in 10 | gas, about 6 in 10 | Copper supply, old enough for pinholes. |
By the numbers

What you’d notice
Look along the copper pipes between the floor joists above your finished basement. A green crust or a damp rust-colored spot on one pipe is a pinhole starting. Put a bucket under it, shut off the water at that run if you can, and call.
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 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.
On a 1960s copper run, fixing the hole is the easy part. A plumber worth calling shows you the pipe, tells you how far the thinning goes, and prices both the patch and the longer fix so you pick with the numbers in front of you.
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.

Tyson was super friendly, and extremely knowledgeable! He fixed my burst pipe faster than I ever could have on my own. I highly recommend SwiftPro services, and will absolutely call them when something inevitably needs repair in the future!

Questions
Two on the same run in a year or so is the point where patching starts costing more than the pipe. One leak by itself is a repair. We’ll tell you plainly which side of that line your house is on.
If you rent, a leak in the house’s pipes is the owner’s repair. Tell them in writing and send a photo. If you own a condo, the shutoff valve in your unit is usually the dividing line, with the building’s risers on one side and yours on the other.
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.
