The Basics
What Is a Slab Leak?
A slab leak is a leak in a water pipe that runs under a concrete floor. The pipe is buried in the ground beneath the concrete, so you can't see it or reach it without the right tools.
Hot water lines leak most often because they expand and shrink every time hot water runs through them. Over years, the pipe rubs against concrete and gravel until it wears a hole.
Do Tigard homes have slabs?
Many Tigard homes sit over a crawl space, not a slab. But slab leaks still happen here more than people think. They show up in:
- Homes built on a concrete slab
- Garages with a slab floor
- Home additions and converted garages
- Water lines running under a concrete driveway or patio
If your home has a crawl space and you think you have a leak, see our leak detection and repair page instead.

Signs of a Slab Leak
If one spot on your tile or floor feels warm, a hot water line under it may be leaking. This is one of the clearest signs.
Damp concrete, water under the flooring or a wet line along the edge of the garage slab. Water from below has to come up somewhere.
Shut off every faucet and fixture and check the meter. If it still moves, water is escaping. Under the slab is one of the most common places.
A hiss or trickle under the floor, especially at night when the house is quiet.
A slab leak runs all day and all night. Even a small one can add a lot to your bill.
Water soaking up from below makes carpet damp, wood floors cup and tiles lift.
If hot water is leaking under the slab, your water heater keeps refilling and heating. You may hear it running far more than normal.
A leak that runs for a long time can wash out the soil under the slab. That can lead to new cracks.
Act Fast
Think You Have a Slab Leak? Do This First

This stops a hot water leak while you wait.
Document wet spots, warm areas and your water meter reading.

Our Equipment
How We Find Slab Leaks Without Breaking Up Your Floor
We don't break concrete to look for a leak. We find it first, then open only what we need to.
We test the hot and cold lines one at a time. This tells us which line is leaking before anything else.
We close off the line and watch the pressure. A drop confirms the leak and how fast it's losing water.
Water leaking under pressure makes a sound. Our listening equipment picks it up through concrete, tile and wood floors.
A thermal camera shows warm patterns on the floor. A hot water slab leak often shows up as a clear warm path.
For tiny or hard to hear leaks, we put a safe gas into the line. It escapes at the leak and comes up through the slab, where our detector finds it.
We trace where your pipes actually run under the floor so we know the path before we pinpoint the spot.
How close can you pinpoint it? In most homes we narrow a slab leak down to a small area, often within a foot or two. We mark the spot and show you why we picked it. We don't open the floor until we're confident.
Your Options
Slab Leak Repair Options
There's more than one way to fix a slab leak. The best one depends on where the leak is, how old your pipes are and what's on top of the slab.
Spot repair
We open a small hole in the slab, fix the damaged pipe and patch the concrete. Fast and costs less up front — but if the pipe is old, another spot can fail later.
Best for: one leak in a pipe that's otherwise in good shape.
Reroute
We leave the leaking pipe under the slab and run a new line through the walls or attic. Your floors stay untouched, and the new line is easy to reach if it ever needs work. Often the smartest choice.
Best for: leaks under tile or wood floors, or pipes likely to leak again.
Repipe
We replace the water lines in the whole house, usually through the attic and walls. Makes sense when the pipes are worn out everywhere — one fix covers everything. See our whole house repiping service.
Best for: older homes with a second or third leak, or worn copper and galvanized pipe.
We'll tell you which option fits your home and why, then give you a price for each.

Local Knowledge
Why Slab Leaks Happen in Tigard
Clay soil that moves
Tigard sits on heavy clay. It swells when it's soaked and shrinks when it dries out in summer. That movement shifts the slab and the soil around the pipes underneath it. Over time, pipes get pushed, bent and rubbed until they wear through.
Long, wet winters
From fall through spring, the ground under Tigard homes stays wet. When a pipe starts leaking, the soil is already soaked, so you may not see a wet spot for a long time. The leak just keeps running.
Copper pipe under older slabs
Many slab homes, garages and additions built from the 1960s through the 1980s have copper water lines buried under the concrete. Copper wears thin where it touches concrete or gravel. Hot lines wear fastest because they expand and shrink every day.
