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 Haymarket
Look at the town itself and you see a middle-aged place. Close to six homes in ten went up between 1980 and 1999, and the typical owner home dates to about 1995. That is the polybutylene window. Builders in those years sometimes ran grey plastic pipe with crimped metal rings, and it can fail at the rings without warning. If your house is from then, find the pipe at the water heater and look at its color.
Bull Run Mountain Estates is the other Haymarket. The median home there dates to 1978, about six in ten were built before 1980, and every one is a detached house. Copper from that era is old enough to pinhole, so a small green crust on a pipe or a damp patch on the floor beneath it should be looked at before it gets worse.
The mountain also has its own water. Prince William Water says the Bull Run Mountain and Evergreen area runs entirely on groundwater, apart from the rest of its system. If you live up there, the pipe from your meter into the house is still yours, but the water inside it can be harder on fixtures and fittings than what flows in town, which is worth mentioning when you call.
In the newer neighborhoods around 20169, about three homes in four date from 2000 or later. Their trouble is usually the back of the house. A hose left connected through a freeze splits the bib or the pipe behind it, and the damage shows in the garage or crawl space days later.
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 |
|---|---|---|---|---|
| Bull Run Mountain Estates | 1978 | single-family houses, nearly all | electricity, about 4 in 10 | Copper supply, old enough for pinholes. |
| Haymarket | 1995 | single-family houses, about 6 in 10 | gas, about 6 in 10 | The polybutylene years: check the supply pipe at the fittings. |
By the numbers
From the Census Bureau’s 2020 to 2024 survey. Median year built and heat count owner-occupied homes only.
Inside the town limits only, about one in eighteen of the owner homes with Haymarket mail. Dominion Valley, Piedmont and Bull Run Mountain Estates sit outside it, in the county.

What you’d notice
If your house has a brick or stone front and siding on the sides, water from an outdoor line can run down inside the wall and show up as a stain in a different room. That’s why we check the whole wall before choosing a spot to open. On the mountain, where the lots are bigger, the same leak can run behind a retaining wall or under a deck for a long time before anyone smells damp.
Polybutylene, often stamped PB, went into houses from about 1978 to 1995. It tends to fail at the fittings without much warning, so a drip at one joint is a reason to look at the rest.
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
Prince William Water requires its own Lateral Repair or Replacement Permit, and its inspection, before anyone repairs or replaces a sewer lateral outside the house. Source.
Prince William Water says the pressure reducing valve is the homeowner’s to install and keep up, that the plumbing code recommends one where pressure runs 80 psi or more, and that pressure rises with the height difference between your house and the water tank serving it. Source.

Choosing who fixes it
Questions worth asking anybody who comes out, us included.
It does. A plumber should ask which side you live on, because the age of the pipe, the water and the likely failure point all differ. If nobody asks, they’re guessing. Say your street name and the year you think the house went up. A mountain address also means the pressure tank and well pump are part of the picture, so say whether the house is on the County line or the well system.
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
Check the lines at the water heater and where the main comes through the foundation. Polybutylene is a flexible grey or silver-blue pipe, held together by metal bands. Anything else, copper or red, blue and white PEX, is a different animal. If you spot grey, call (703) 997-9757 before a band lets go.
Prince William Water’s rule is that you answer for water once it passes the meter. A break in the street before it is theirs to repair. Anything from the meter to the house, including a line under your own driveway, is yours.
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.
