Water Line Repair & Replacement in Longmont, CO
The line from the meter to your house is a different job than the pipes inside it. We locate, repair, or replace it, trenchless where the site allows.
The water service line is the buried pipe carrying water from the city meter or curb stop to the house, separate from the supply lines inside the home, which is what repiping addresses instead. A problem here shows up differently than an inside leak, and needs a different fix.
A break or major corrosion in this line is a genuinely different job than an inside pipe repair, since it means excavation or trenchless work under the yard rather than accessing a wall or ceiling.
No Water at All, But Your Neighbors Have Theirs?
A total loss of water while neighboring homes are unaffected points specifically to this home's own service line rather than a city-side issue. A soggy or unusually green patch of yard between the street and the house is another classic sign, and so is the water meter continuing to spin with every fixture inside shut off. Both lead someone here before they've ever used the term water line themselves.
Signs of a Water Line Problem
- No water at all, while confirmed neighboring homes have normal service.
- A consistently soggy, unusually green, or sunken area of yard between the street and the house.
- The water meter keeps spinning with every fixture in the house shut off.
- Noticeably low water pressure throughout the entire house, not just one fixture.
- A sudden spike in the water bill with no other explanation.
Why Water Lines Fail in Longmont
Original lead or galvanized service lines are a real, documented condition in Longmont's older neighborhoods, and a line that old is corroding along its length the same way an interior galvanized pipe does, just buried and harder to notice until it fails outright.
Freeze depth and expansive clay soil both add real stress specific to a buried line. A line that isn't buried deep enough for the area's frost line is at real freeze risk, and clay soil's seasonal swelling and shrinking puts ongoing mechanical stress on the pipe over years.
How We Diagnose a Water Line Problem
Diagnosis starts by checking the water meter with everything in the house shut off, since continued movement narrows the problem to somewhere between the meter and the house rather than inside it.
From there, acoustic leak detection equipment traces the line's path to pinpoint the leak location before any digging starts, the same core method used for leak detection generally, applied specifically along the service line's path.
Repair or Replace?
- Spot repairThe right fix for a single, isolated break in an otherwise sound line.
- Trenchless replacementPulls a new line through the original path using directional boring, often avoiding a full open trench across the yard.
- Traditional open-trench replacementSometimes still necessary depending on the line's path, depth, and nearby utilities.
What Water Line Repair or Replacement Costs
Cost depends on the line's length, depth, and whether trenchless replacement is possible on the specific site.
- Repair vs. replaceA single spot repair costs less than replacing the full line.
- MethodTrenchless replacement is often less disruptive but depends on soil conditions and the line's path.
- Depth and distanceA longer or deeper run from meter to house adds cost.
- Permit and city coordinationWater line work often involves coordination with the city connection point in addition to the standard DORA permit process.

Frequently Asked Questions
How is a water line different from the pipes inside my house?
The water line runs underground from the city meter or curb stop to the house. The pipes inside the house, addressed under repiping, are a separate system entirely.
Do I need to dig up my whole yard for a water line repair?
Not necessarily. Trenchless replacement can often pull a new line through the original path without a full open trench, depending on the site.
Why is my water bill high with no other symptoms?
A leak in the service line between the meter and the house runs continuously and often shows up as a high bill before any visible sign appears above ground.
Do you handle emergency water line breaks?
Yes, a total loss of water or an active break is treated as an emergency call 24/7 in Longmont and the surrounding service area.
