Monthly figures: 60mo @ 0% APR on each starting price, the whole price financed, on approved credit. Longer plans lower the payment and cost more in total. The lender sets the final terms. How financing works
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.
With Comfort+ membership, any service is 15% off, and a water heater flush with a sewer camera inspection and a plumbing safety inspection comes every year.
Recent work
What our technicians found and fixed on visits in Reston, from their notes on each job.
October 2026
Two bathroom faucets leaking at the hot handle: the old hot side cartridges, seats and springs out, new ones in, and both faucets checked for leaks.
September 2026
A sewer camera inspection for a house under contract: the line leaves the house as plastic and turns to cast iron underground, with wipes built up along the bottom and standing water from about 10 to 14 feet out.
September 2026
A leaking 50 gallon electric water heater replaced, with a new pan and expansion tank, the air bled out of the lines and the hot water checked.
Who comes out
Two of the people we send, in their customers’ own words from our Google reviews. The same team covers Reston from our Chantilly shop and our Ashburn office.
I had a blockage in my pipe and James snaked it through and took out some weird wire that the tenant left in there.
He fixed the plumbing problem at hand and identified the cause of a different issue. He was respectful, wore booties to keep my home clean, and worked quickly.
What’s different in Reston
Reston’s pipe depends on when your corner of it went up. In 20191, around Hunters Woods and South Lakes, nearly half the homes date from the 1970s: typically copper supply and cast iron drain stacks. Cast iron of that age rusts thin along its floor, where water sits, and a camera, $89 added to a visit, shows how much is left before anybody opens a wall.
North Point and the rest of 20194 went up almost all at once: more than eight in ten homes there are from the 1980s and 90s, mostly the years grey polybutylene supply pipe was going into new construction. Look under a sink or behind the tub’s access panel before a fitting picks the day for you; replacing it runs $1,000 to $12,000, and where yours lands depends on how many rooms it feeds.
In 20190, from Lake Anne to Reston Town Center, more than half the homes are in condo and apartment buildings, and about four in ten went up after 2000. A building’s shared risers and stacks are usually the association’s, and what branches off them inside your unit is yours. In a cluster, the sewer line past your front walk may cross common area the cluster association owns, so check its documents before a dig.
Fairfax County bills a home’s sewer on the lower of this quarter’s water use or the last winter quarter’s. A toilet that runs all winter raises that ceiling for the year that follows, so fix it before winter; toilet repair runs $250 to $900. And with about four in ten of Reston’s occupied homes rented, an empty unit between tenants is where drain traps dry out.
Neighborhood by neighborhood
Census figures for each place, and the 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 pipe you usually find |
|---|---|---|---|---|
| Reston | 1981 | condo and apartment buildings, about 4 in 10 | gas, about 5 in 10 | The polybutylene years: check the supply pipe; PVC drains. |
| Great Falls Crossing | 1993 | single-family houses, about 9 in 10 | gas, about 8 in 10 | The polybutylene years: check the supply pipe; PVC drains. |
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
Every drain holds a little water in its trap to block sewer gas, and a shower or floor drain nobody uses dries out. Fairfax County’s advice is a gallon of water down the drains and sinks that don’t get used often. If the smell returns within days, a trap or vent needs a look.
Polybutylene, often stamped PB, went into houses from about 1978 to 1995. It tends to let go at the fittings with no warning, so it’s worth knowing whether you have it.
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.
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.
Your pipes, your paperwork
In Fairfax County the homeowner owns the whole sewer lateral, from the house to the county main, including the stretch under the street. Replacing it takes a county plumbing permit, plus a VDOT permit under a state road. Source.
Fairfax Water promises 20 psi at the main and no uniform pressure, and the pressure reducing valve on your side of the meter is yours to buy and keep up. Over 80 psi, the Virginia Residential Code calls for one, and an expansion tank with it. Source.
Our Virginia Class A contractor license, 2705192276, is on the side of the van.
Choosing a plumber
Questions worth asking anybody who comes out, us included.
If sewage comes up with every tap off, Fairfax County wants the first call, and a county inspector looks at the main before anyone runs a cable through your line. Anyone plumbing in Reston should ask that first.
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.

James M. did a great job diagnosing and fixing the issues I was having with two of my toilets. He was friendly, professional, and worked quickly while making sure everything was repaired correctly. I really appreciated his knowledge and efficiency.

Questions
Fairfax County first, on its 24-hour line, 703-323-1211. With no water running, the trouble may be in the county main. If the county finds its line flowing, the blockage is most likely in your lateral, and main sewer line cleaning runs $550 to $1,650. Until then, plug the drains and run no water.
Yes, especially by fall. Reston’s water generally comes from Fairfax Water’s Corbalis plant on the Potomac, which in 2025 measured about 4 grains per gallon in May and almost 11 in November. That’s enough to crust aerators and shower heads, wear toilet fill valves and settle scale in a water heater.
Yes. We can set the visit up with your tenant and email you the price before any work starts, then the write-up after. If the leak is coming from above, find out first whether it’s your unit’s branch or the building’s riser; the riser is usually the association’s.
Yes. A tank runs $2,757 to $7,494 installed, with the pan, the expansion tank and the haul-away in the number. From about $46 a month at 0% APR for 60 months, the whole price financed, on approved credit. Plenty of Reston condos are all electric, and there the right replacement is usually another electric tank: a whole-house electric tankless heater needs more electrical capacity than most condo panels have.
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.
