Water Line Repair & Installation in McLean, VA — Main Lines Near Me
One buried pipe supplies every faucet, shower, and appliance you own. When the private water line between the meter and your house leaks, corrodes, or proves too small for the home it now serves, the symptoms show up everywhere at once. This page covers that supply line specifically — not drains, not the sewer lateral, which has its own page under sewer line repair. Our full range is listed on the McLean homepage.
Supply leaks behave differently from drain trouble, because this water is clean, pressurized, and metered. It leaves fingerprints a drain never would.
The meter is the first witness. Movement on its low-flow dial while the house uses nothing means pressurized water is escaping somewhere between the street and your fixtures. On the property, a service line leak often surfaces as a mysteriously green or soggy stripe in the lawn along the line’s path, even through a dry August.
Inside, the house complains in chorus: pressure that fades when a second tap opens, a washing machine that fills slowly, irrigation that cannot hold its zones. A single weak fixture is a fixture problem; a weak house is a line problem until proven otherwise.
Meter creep with every fixture and appliance in the house off.
House-wide pressure loss that arrived gradually over months.
Wet or lush soil tracing a line from the meter toward the foundation.
Discolored water after the line is disturbed or the main is worked on.
Hissing or running-water sounds in the ground or at the foundation wall.
Repair or Replace the Run?
A service line with one honest failure — a fitting that let go, a section nicked by a shovel or a root — can often be repaired at that spot, with healthy pipe joined on both sides and the trench restored. Lines tell a different story when corrosion is general. Older galvanized services rust from within until the bore narrows like a closing fist; those lines do not need a patch, they need retiring.
Replacement runs a new line, typically modern plastic rated for potable service, along the cleanest practical route, and it solves pressure and reliability together. On McLean’s deep lots the run can be long, and we will measure the route, count what it crosses, and price the real job before digging. When the location of a leak is uncertain, our water leak detection process finds it first.
Pressure fading across your whole McLean house? That is the supply line introducing itself. Call (855) 913-0016 before it becomes a yard excavation on its own schedule.
Long Runs and Old Metal in McLean
McLean’s generous lots mean generous distances between meter and house, and every extra foot is another chance for soil, roots, and time to work on the pipe. Homes in Langley and along Chain Bridge Road can carry service runs far longer than a typical suburban lot, which is why leak location here is a discipline of its own.
The oldest services in neighborhoods like Chesterbrook began as galvanized steel, and many have quietly narrowed for decades; homeowners adapt to fading pressure so gradually they forget what full pressure felt like. A replacement line often feels less like a repair and more like the house waking up.
New Lines for New Demands
Installation is the other half of this service: first-time water lines and upsized services for homes that have outgrown their original pipe. A 1960s service sized for two bathrooms strains under a renovated house with five, plus irrigation, plus a pool fill line. The pressure math stops working no matter how healthy the pipe is.
Additions, new construction on McLean’s teardown lots, and detached garages or pool houses all need planned water service too. We size the line to the fixture count and distance, coordinate the meter-side connection within the county’s rules, and pressure-test the whole run before the trench closes.
The Meter Is the Border
Responsibility for water lines splits at the meter. Fairfax Water maintains the public main and its side of the meter. Everything from the meter across your lawn and into the house is private, which means leaks there run on your bill and repairs there are your project.
That border also decides who to call. Water bubbling in the street or at the meter pit itself belongs to the utility. Water vanishing between the meter and your walls, with the meter spinning to prove it, belongs to us. If you are unsure which side is failing, the isolation test at the house valve answers it, and we are happy to walk you through it by phone at (855) 913-0016.
Pricing Factors
What Water Line Work Near Me Costs, and Why
Buried supply work is priced by the route the pipe has to travel and what it travels through.
Length of the run from meter to house entry
Depth of the existing line and the frost depth it must respect
Driveways, walls, patios, and mature trees along the route
Pipe size the home’s fixture count honestly requires
Whether a spot repair suffices or the line’s condition argues for replacement
Surface and lawn restoration once the trench closes
Permit and inspection steps for new or replaced services
You will see the route, the reasoning, and the price together before digging starts. If a repair will serve, we will not sell you a replacement.

Questions & Answers
Water Line FAQs
Watch the meter with the house using nothing: movement means loss. Then look for the yard’s testimony, a soft or green stripe over the line’s route, and listen for pressure complaints from the whole house rather than one tap. Those three together make a strong case before any digging is discussed.
Yes, when the rest of the pipe is sound. We excavate at the located fault, cut back to healthy material on both sides, and join the new section with proper fittings. If inspection shows corrosion along the run rather than at a point, we will recommend replacement and show you the evidence from the exposed section.
Gradual, house-wide pressure loss usually means the service line’s bore is narrowing with rust and scale, or a leak is diverting flow. A failed pressure-reducing valve produces similar symptoms and is cheaper to fix, which is why diagnosis starts at the valve and meter before anyone blames the buried line.
It depends on fixture count, simultaneous demand, and the run’s length. A house with five bathrooms, irrigation, and a long setback from the meter can outgrow a line that served a smaller original house perfectly. We calculate from your actual fixtures rather than copying the old pipe’s diameter out of habit.
Deep enough to sit below the frost line, which in Northern Virginia means roughly two and a half to three feet in typical installations. That depth protects against McLean’s January cold, and it also means excavation for repair is real work, one more reason to locate the fault precisely first.
You are. Fairfax Water maintains the public main and its side up to the meter; the service line across private property belongs to the homeowner, including its leaks and its water bill consequences. That is the portion we repair and install.
The route decides. Some properties allow a path along a driveway edge or through open lawn that restores cleanly; others cross walls, patios, and root zones that must be worked around. We walk the route with you and explain the disturbance honestly before pricing, so there are no landscaping surprises.
