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 Gainesville
Roughly eight owner homes in ten here went up in 2000 or later, so a typical Gainesville leak isn’t a worn-out pipe. It’s a joint. Look at the places where one material meets another: the copper stub coming out of a PEX run, the shutoff valve under a sink, the line feeding the ice maker. Those connections take years of small temperature swings before they weep.
Virginia Oaks, with 561 homes along Lake Manassas, goes back to 1994. That puts it in the stretch when some builders were still using grey polybutylene, so if you own one of the older Oaks houses, check the pipe near your water heater. Grey plastic with metal crimp rings is the tell. Newer streets around it are a different story, with the usual 2000s mix of PEX and copper.
Heritage Hunt is its own case. It’s a gated 55-and-over community of 1,863 homes, and a few of them are condos. If you live in one of the condos, the pipe inside your wall may belong to the association and the pipe past your unit’s shutoff to you. Ask the management office before you hire anyone, because the wrong call means paying for a repair that wasn’t yours.
About a third of Gainesville homes are townhouses, and that changes what a ceiling stain means. Water runs along a joist before it shows, so the stain can sit a room away from the break. Turn off your main and keep an eye on the spot through the evening. If it dries, the leak was yours. If it still spreads, it’s coming from the other side of the wall.
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
In a house with a finished basement, there’s a drywall ceiling under the first-floor plumbing. A slow drip behind that ceiling can run for weeks before anything shows. A faint brown ring, or drywall that feels soft near a joint, is the signal to call before the paint bubbles. A soft baseboard along an outside wall in a Heritage Hunt ground-floor unit is another early sign.
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.
A bill that’s a third higher with nobody new in the house is often a running toilet, and sometimes a pipe. The meter test above sorts out which in a few minutes.

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 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.
Worry less about the wall and more about the plumber’s plan. A good one finds the spot with a moisture meter or a camera, cuts one small opening where the pipe really is, and tells you what the patch will look like. A bad one cuts a long trench through drywall to see what’s behind it. In a house near Lake Manassas, ask whether they will check the crawl space or utility room beneath the stain, since that’s where a slow drip often collects first.
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
With the meter. Shut every tap and appliance, then watch the dial or the small triangle that spins with flow. If it moves, close the main inside the house and look again. Movement after that points to the yard line, and a still dial means the leak is inside. Call (703) 997-9757 with what you saw and we’ll take it from there.
Prince William Water puts the dividing line at the meter. Water pooling in the street before it is their concern. Water in your yard after it comes from a line on private property, which is the owner’s to repair.
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.
