A sewer camera inspection is $89 added to a visit we’re already making. It’s the cheapest way to know what a drain is doing before anybody talks about digging.

Recent work
What our technicians found and fixed on visits in Ashburn, from their notes on each job.

September 2026
A new elongated toilet in a hall bathroom, set on a new wax seal and bolts, caulked and checked for leaks.
September 2026
A slow kitchen sink drain snaked about 50 feet, past something hard halfway down, then filled and drained several times until it ran clear.
Who comes out
Two of the people we send, in their customers’ own words from our Google reviews. The same team covers Ashburn from our Chantilly shop and our Ashburn office.
Our water heater failed at 8pm on a friday night, by 10am the next morning, Harold was at our house, removed the broken heater, and installed the new one.
Jimbo, was warm, professional and articulate in providing plumbing services. He truly is a man that knows his craft.
What’s different in Ashburn
Loudoun Water disinfects with chloramine, and its 2025 water quality report names the catch: chloramine can make certain gaskets and toilet flappers wear out faster, and that leads to leaks. So when an Ashburn toilet keeps hissing and refilling or a faucet won’t quit dripping, the rubber parts are the first suspect, and fixing the toilet is $250 to $900. The same report says Loudoun Water has no lead service lines anywhere in its system, an inventory the state health department has accepted.
Behind the walls, Ashburn’s plumbing is young. Only about two homes in a hundred predate 1980, so you’ll rarely find galvanized steel or cast iron here. The exception is polybutylene. In Ashburn proper, around Ashburn Farm and Ashburn Village, roughly half the homes were built between 1980 and 1999, and builders were still running grey polybutylene supply lines into the mid 1990s. If the pipe coming off the top of the water heater is grey plastic marked PB, the polybutylene guide on our blog covers the choices, and a repipe is $1,000 to $12,000.
When the main drain backs up, Loudoun Water’s own rules say to call Loudoun Water right away. It checks whether the stoppage is in the public sewer and clears it if it is. If the blockage sits in your own building sewer, it tells you to hire a licensed plumber. That’s the call we take: clearing the main costs $550 to $1,650, and a look down the line with our camera on the same visit shows what caused it.
Hidden leaks have one consolation on the bill. Loudoun Water can grant a one-time courtesy credit for a hidden indoor or irrigation leak, covering the overage on both water and sewer, but only once per account and only with paperwork showing the fix. If the utility spots the leak first, you get 30 days to repair it or the credit is off the table. Finding a hidden leak is $200 to $500.

What you’d notice
Loudoun Water’s FAQ traces black particles to rubber gaskets and O-rings breaking down, or to a carbon filter cartridge, and suggests chloramine-resistant replacements. It’s a small repair, and the toilet flappers deserve a look for the same reason.
A damp patch on a ceiling, a warm spot on the floor, a meter that keeps ticking with every tap off. A slow leak inside a wall does most of its damage before it ever shows itself.
One slow sink is a sink. Two slow drains on different floors are sharing the pipe out to the street, and a basement drain that gurgles while you run water upstairs is the main line talking.
Lukewarm showers, hot water that runs out halfway, banging or rumbling from the tank. Rumbling is sediment, and it’s the noise a water heater makes in its last couple of years.
After a heavy rain
Heavy rain finds the weak spots in a house’s plumbing. Four checks you can make yourself, then call us and we’ll look at the rest.
Clear water with no smell is usually groundwater. Gray water, or a sewer smell, means the main line is backing up: stop running water in the house and call us.
A main line with a cracked joint or roots in it can take in groundwater during a storm and slow down. A sewer camera inspection, $89 added to a visit, shows where.
If the house has one, watch it once: it should start as the pit fills, empty it and shut off. Our sump pump replacement page has the rest of the checks.
If floodwater got to a gas water heater’s burner or controls, leave it off. Don’t relight it until a plumber has checked it.
Call us after a storm and we’ll check it all: the floor drains, the main line, the sump pump and the water heater. Any repair gets its price in writing before the work starts.

Choosing a plumber
Questions worth asking anybody who comes out, us included.
If the stoppage is in the public sewer, Loudoun Water clears it. Anyone who plumbs in Ashburn should ask before snaking your line, so you don’t pay to clear a clog that was never in your pipe.
Anyone can check on the state’s license lookup in about a minute. It’s the one question that takes the guesswork out of the rest.
A sewer camera inspection is cheap next to any dig, and it shows whether the problem is a root, a sag or a break. A quote to dig without one is a guess.
Every plumbing job on our list has a range. A plumber who won’t say where yours lands until the wall’s open is asking for a blank check.

Tyson did a great job on several minor items along with repairing two toilets. He was courteous, quick, clean, and friendly.
Questions
That depends on which side of the connection it’s on. Loudoun Water maintains its main and the water service connection and repairs leaks there at no cost to you. From there in, the building service pipe and all the piping in the house are yours, and Loudoun Water’s rules call for a registered plumber to fix them.
By appointment in business hours, sometimes for a fee. Its rules make the regulator where the water line enters your house your responsibility, so the quicker check is a pressure gauge screwed onto a hose bib: past 80 psi, the regulator has given out or was never installed. A new one costs $500 to $1,000.
Yes. We run 24/7 emergency service, out of our Ashburn office and our Chantilly shop. While you wait, close the main shutoff and open a faucet on the lowest floor to drain the pressure off the leak; Loudoun Water asks every household to know where that shutoff is before the night it’s needed.
Across the county, from Sterling and Ashburn out to Leesburg, Purcellville and Lovettsville. Each town has its own page with its own water and rules, like a plumber in Sterling or a plumber in Leesburg, and everything we do in Loudoun County starts from one page.
It depends on the job, and every one has a published range: drain cleaning for one fixture $200 to $800, main sewer line cleaning $550 to $1,650, leak detection $200 to $500, a pressure reducing valve replacement $500 to $1,000, toilet repair $250 to $900. A sewer camera inspection added to a visit is $89.
