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 Hamilton
The water in Hamilton comes out of three wells the Town runs itself, chlorinated, with the iron and manganese taken out. That’s useful to a plumber. Iron and manganese are what leave orange and black stains, so when rusty water comes out of one tap, or only the hot side, the Town’s supply is less likely to be the cause and your own pipe or water heater is more likely. Hamilton also reports that none of its service lines are known to be lead.
Whose pipe is it? The Town’s rules put the water line from the meter box on the owner, so a wet patch between the meter and your foundation is yours to fix. Water coming up at the meter itself, or out in the street, is the Town’s. Take a photo of the wet spot before anyone digs, and note where it is relative to the meter box. That one photo saves a lot of back and forth.
Hamilton has a written leak adjustment policy for water bills, and it asks for particular things: the repair documented, the request made before the bill is due, and no other adjustment in the last 36 months. So the invoice matters as much as the fix. We write down what we found and where, so you have something to hand the Town Hall clerk. Ask the Town for the current form, since the details change.
The houses sort into three groups. About one owner home in six in the ZIP is from before 1960, the old village and farmhouses, where galvanized steel can still be hiding. A fifth went up between 1980 and 1999, when polybutylene was common. And over four in ten are since 2000, where PEX and copper hold up and the trouble is a fitting or a hose bib. Nine in ten are detached houses, so a leak is usually yours alone.
By the numbers
From the Census Bureau’s 2020 to 2024 survey. Median year built and heat count owner-occupied homes only.
ZIP 20158 as a whole: every Hamilton address, the Town and the countryside around it. The Census place for the Town alone has too few homes for steady figures.
What you’d notice
If the cold side runs clear and the hot side comes out orange, the water heater is the usual suspect, not the Town’s wells. A tank that’s rusting from the inside will also weep at the bottom, so look at the floor under it.
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.
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
Our Virginia Class A contractor license, 2705192276, is on the side of the van.
Choosing who fixes it
Questions worth asking anybody who comes out, us included.
If a leak ran up your bill, you may want an adjustment. A plumber who works in Hamilton knows to put the date, the location and what was repaired on the invoice, so the paperwork is there when you need it.
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 helpful, patient, and great to work with! He helped diagnose the cause of a leak narrow down what appliance needed fixing. Will definitely use Swift again!

Questions
The Town has a written policy, and it looks for a documented repair, a request before the due date, and no other adjustment in the last 36 months. Check the current form at Town Hall. We can’t promise the Town’s answer, but we make sure the repair is on paper.
Between the meter box and your house it’s yours. At the meter or toward the street, call the Town. If you can’t tell, don’t dig; call us at the number above and we’ll look at where the line runs.
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.
