Main Water Line Replacement Cost: Meter to House
Replacing the main water line from the meter to the house runs $50 – $250 per linear foot, which puts a typical 40 to 60 foot run at $1,500 – $8,000. Trenchless pull-through costs more per foot but saves your driveway and landscaping. The line from the meter to your house is yours to maintain, and a wet spot in the yard with dropping pressure is usually how it announces a failure.

Who owns what: the line is on you
The water system splits ownership at the meter or the curb stop. The utility owns the main in the street and usually the connection up to the meter. From the meter to your house, the service line is yours, and so is the bill when it fails. That ownership line catches homeowners off guard, because the broken pipe is buried in their yard but feels like the city water company should fix it.
Knowing where your responsibility starts also tells you which repairs are yours to schedule. A leak between the meter and the house is a service-line replacement on your dime, while a problem on the street side is a call to the utility. Older homes sometimes find the failing line is original galvanized pipe, which corrodes from the inside. When in doubt, the meter is the dividing line.
The symptoms: wet yard and dropping pressure
A failing service line announces itself two ways. The first is a soft, wet or unusually green patch in the yard along the line path, sometimes with water pooling at the surface, that persists through dry weather. The second is a drop in whole-house water pressure as water escapes underground before it reaches the house.
Two checks confirm it. Watch the meter with every fixture off: if the dial creeps, water is escaping somewhere on your side. And compare your water bill month over month, a sudden spike with no change in usage points to a buried leak that a leak detection visit can pinpoint. Once both line up, the line is failing and a spot repair on an old pipe usually just buys a few months before the next break.
Trenchless vs open trench
Open-trench replacement digs the full path from meter to house, $50 – $150 per foot. It is straightforward on an open lawn, but if the line runs under a driveway, sidewalk or mature landscaping, the restoration cost can dwarf the plumbing.
Trenchless methods (pipe bursting or directional boring) cost more per foot at $100 – $250 but need only two small access pits, one at each end. The machine pulls new pipe along the old path, leaving the surface in between untouched. On a lot with hardscape or established trees, the savings on restoration often make trenchless the cheaper total, even at the higher per-foot rate. Ask both methods to be quoted with restoration included so you compare the real bottom lines.
Depth, frost line and region
How deep the line sits drives a lot of the cost, and that depth is set by your climate. In warm regions a service line may sit 18 to 30 inches down; in cold-winter states it must be buried below the frost line, often 4 to 6 feet, to keep it from freezing. Deeper trenches mean more excavation, more shoring, and a higher per-foot price.
Region also dictates material and permitting. Modern service lines are usually PEX, HDPE or copper, and the choice may be set by local code. A permit and inspection ($100 – $600) is standard, and the connection at the meter or curb stop typically requires utility coordination. Factor a day or two of lead time for that sign-off into the schedule.
What the replacement visit looks like
The crew marks the line path (and has utilities located first to avoid gas and electric), pulls a permit, and either trenches the run or sets two pits for a trenchless pull. New pipe goes in, gets connected at the meter and the house entry, and is pressure-tested and inspected before backfill. A typical 40 to 60 foot run is a one to two day job.
Restoration is the variable. On open lawn, the crew backfills and reseeds. Where the path crossed a driveway or patio, concrete or paver replacement is a separate line and a separate trade, which is exactly why trenchless wins on hardscaped lots. Confirm what restoration the quote includes before you sign.
