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 The Plains
Here is the thing only this town has. The Plains gets its water from FCWSA’s own system for the town: two drilled wells, 415 and 610 feet deep, pump into an above-ground tank set higher up, and the height of that tank is what pushes water through the pipes. Pressure comes from gravity, not a pump in your basement. In a system like that, houses lower down usually see more of it than houses on the rise, and FCWSA says that over 80 psi is where the customer should put in a pressure regulating valve.
If you have had two small leaks in a few years at fittings that otherwise looked fine, a gauge on an outside spigot is the first thing we check. It takes a minute. High pressure doesn’t show up as a flood; it shows up as a drip at a joint and a stain on the ceiling below. A regulator is a small part, and it protects every pipe in the house after it.
Only about one home in ten in the 20198 ZIP is inside the Town. The rest are on farms and big lots, so before you call, know which one you are: in town, water comes from the system; outside, it comes from your own well and tank. By 1977 the town system had replaced many of the individual wells, so most houses inside the limits have been on it for decades.
Inside the limits, the houses are older than the ZIP as a whole. Of the 140 properties in the Historic District, nearly half date to 1900 to 1930 and almost a quarter to the 1940s and 1950s. Stone is common in the foundations, and several houses are set into a bank with a basement door at the lower side. The Cape Cods on Loudoun Avenue and the brick-veneer houses on Mosby Street are post-war, so usually copper, not steel. The older ones, and the 1920s kit house, are where we expect galvanized somewhere in the wall.
By the numbers
From the Census Bureau’s 2020 to 2024 survey. Median year built and heat count owner-occupied homes only.
ZIP 20198 as a whole, the Town included: its own homes are too few for steady Census figures.
What you’d notice
If the same joint or a different one every year starts to weep, the pressure may be too high, or the pipe may be getting old. A gauge tells us which. If pressure is fine, the pipe is the cause, and we price replacing the run, not another patch.
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
On FCWSA sewer, the service line from the main to the property line and the lateral from there to the house are the customer’s to clear. FCWSA clears its mains and fixes a service line under a public street, and it doesn’t reimburse a plumber. Source.
On FCWSA water (Bealeton, Catlett, Marshall, New Baltimore, Vint Hill and its other systems), FCWSA says it can’t guarantee uniform pressure, and that over 80 psi the customer should install a pressure regulating valve at their own expense. Homes on private wells aren’t covered by this. Source.

Choosing who fixes it
Questions worth asking anybody who comes out, us included.
In a tank-fed system like The Plains’, they should. A plumber who reads the pressure at the spigot can tell you whether a regulator is part of the job, and what to expect if there isn’t one.
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
The Town’s rule covers improvements, and a repair inside a wall that changes nothing outside is a different thing. If the fix changes anything you can see from the street, the Architectural Review Board is the one to ask. We’ll tell you which kind of job it is before we start.
Probably not. Most of the ZIP is private well country, where the pressure tank is the starting point and nobody else owns the line. Tell us on the call which it is, and we’ll bring the right tools.
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.
