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 McLean, from their notes on each job.
October 2026
A sewer camera inspection on a house being sold. With no cleanout to use, the downstairs toilet came up so the camera could go in: cast iron under the house, then Orangeburg pipe outside, flattened in places, that stopped the camera about 45 feet out. The toilet went back on a new wax ring.
September 2026
Four days replacing every horizontal hot and cold copper line in a basement ceiling and crawl space, from the well pump to the risers that feed the main floor.
September 2026
A toilet that wouldn’t stop running. The fill valve had failed, so a new one went in and the toilet was tested.
What’s different in McLean
Close to four in ten homes in 22101 went up in the 1950s and 60s, and about one in five in the McLean Census area before 1960. Under a house from those years the drains are usually cast iron, which scales up inside until every clog comes back sooner. The supply is copper, or in the oldest houses galvanized steel, which rusts shut from the inside until an upstairs shower runs weak.
The line from the street is the easy part: as of November 2025 the water utility’s service line inventory lists no lead line in McLean or Tysons. Most of McLean drinks Potomac water treated at the Washington Aqueduct, 5.6 to 10.9 grains per gallon in 2025 and hardest in December: the white crust on aerators and the sediment in a tank.
Newer houses can hide an older pipe. About one home in seven in 22101 went up in 2010 or later, and when a new McLean house replaces an old one, the county lets the builder keep the existing sewer lateral only if a video of it is uploaded and approved before the plumbing passes final inspection. So a new house on an old McLean lot can drain through a lateral laid decades before it. A camera, $89 added to a visit, shows roots, a sag or a break; our McLean sewer line repair page takes it from there.
22102 is mostly towers: close to half its homes are in buildings of 50 units or more, and more than half are rented. The pipes that serve every floor usually belong to the association, and what branches off them into your unit is yours: shutoffs, supply lines, fixtures and the water heater, often an electric tank in a closet.
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 |
|---|---|---|---|---|
| McLean | 1977 | single-family houses, about 8 in 10 | gas, about 7 in 10 | Copper supply, cast iron drains. |
| Tysons | 1985 | condo and apartment buildings, about 7 in 10 | electricity, about 5 in 10 | Condo buildings: shared risers, your own supply lines and fixtures. |

What you’d notice
In a building, a drip from the ceiling can start in the unit above, not in yours. Close your unit’s main shutoff and watch: if it keeps dripping, the pipe isn’t yours, so call management and knock upstairs before anyone opens your ceiling.
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.
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.

Choosing a plumber
Questions worth asking anybody who comes out, us included.
A new 22101 house can drain through a lateral older than the house, if the builder kept it with the county’s video sign-off. A plumber who knows that puts a camera in from the cleanout before blaming the new pipe or quoting a dig.
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.

Needed a consult for a possible plumbing problem I couldn’t diagnose myself – they checked out the problem areas, figured out what needed fixing, and were super clear and kind. I feel so much better and have the plan for next fixes. Thank you!

Questions
A tank water heater runs $2,757 to $7,494 installed, and tankless $8,886 to $10,486. The water heater estimator narrows that to your house, and our McLean water heater page has the rest.
No. As of November 2025 the water utility’s inventory lists no lead line, and none of unknown material, anywhere in McLean or Tysons. That’s the pipe from the street to your house. Past the wall the plumbing is yours, and in a McLean house from before 1960 it may still be galvanized steel.
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.
