- A single, easily located leak under soil is often fixed in one visit.
- Finding the leak can take longer than repairing it.
- Concrete, depth and full replacement are what stretch timelines.
Two neighbors on the same street can call about the same problem, a leaking water service line, and have very different days. One has the water back on by lunchtime. The other is looking at a multi-day job. The difference almost always comes down to the five factors below.
The five factors that set the timeline
1. How easy the leak is to find
If water is bubbling up in one obvious spot, locating is quick. A silent leak draining into gravel is different: the provider may need to trace the pipe's route and use acoustic equipment or tracer gas to pinpoint it. Locating can genuinely take longer than repairing. Our guide to finding underground leaks explains why.
2. What's on top of the pipe
Lawn and planting beds are quick to open and close. Pavers can be lifted and relaid. Concrete and asphalt need saw-cutting and patching, and new concrete needs time to cure before it can take traffic, which can add days to the overall job even if the plumbing part is quick.
3. Depth and access
A shallow line in an open front yard is a small dig. A deeper line, a narrow side yard, a slope, or other utilities crossing nearby all slow careful excavation.
4. Pipe material
Joining new pipe to sound copper or plastic is straightforward. Old galvanized steel can crumble when disturbed, which sometimes turns a short repair into a longer one as more pipe needs replacing to reach solid material.
5. Extent of damage
One leak is one repair. Several leaks, or a line that's failing along its length, point toward replacement, which is a bigger job.
Typical scenarios
| Scenario | What to expect |
|---|---|
| Visible leak under lawn, sound pipe | Often completed in a single visit |
| Hidden leak needing location equipment | Locating may be a separate step before the repair |
| Leak under a concrete driveway or path | Repair plus concrete work; surface restoration may take longer |
| Full service line replacement | A larger job; ask the provider for a schedule |
| Permit required for the work | May add inspection scheduling |
How long will the water be off?
Usually for less time than the whole job. The water has to be shut off while the damaged section is cut out and replaced, but locating and digging typically happen with the water still on (or turned on between steps). Ask your provider to warn you before the shut-off so you can fill a few containers.
Ways to speed things up
- Run the meter test before you call, so the provider knows it's an outside leak.
- Mark any wet spots and tell the provider where sprinkler lines, lighting and your sewer cleanout run.
- Clear vehicles, planters and furniture from the likely work area.
- Ask up front whether a permit is needed and whether surface restoration is included.
