Exterior Water Assessment
We check grading, downspout placement, and drainage patterns around your foundation, since these cause a large share of the moisture problems we see.
Before a crack becomes a bigger problem
Foundation Leak Detection in Stillwater
Stillwater sits on Permian red clay, soil that swells when it's wet and shrinks when it dries. That movement is the single biggest reason local foundations crack, and a leak, whether it's a plumbing line or bad drainage saturating the soil around your footings, speeds it up. We find where water is getting to your foundation before it does more damage.
Careful work. Honest options.
About this service
Slab Leak vs. Foundation Leak: Not the Same Thing
A slab leak is a pressurized water line leaking under your concrete floor. A foundation leak is water reaching your foundation walls or footings from somewhere else, often a grading problem, a failed gutter downspout, or groundwater pooling against the perimeter after rain. Both are serious. They're diagnosed and fixed differently.
We check both plumbing sources and exterior water management as part of a foundation inspection, since clay soil makes it easy for one to look like the other. Cracks that open and close seasonally usually point to soil movement rather than an active leak, and we'll tell you which one we're looking at.
- ✓ Distinguishes plumbing leaks from drainage-related foundation issues
- ✓ Exterior grading and downspout inspection included
- ✓ Moisture meter readings at foundation walls
- ✓ Clear explanation of clay soil's role in what we find
What's included
What's Included
We check the whole picture, not just the crack you called about.
Interior Moisture Readings
Moisture meters at baseboards and foundation walls show where water is actually getting in, not just where it's visible.
Plumbing Line Check
Supply and drain lines near the foundation perimeter get tested to rule out a leak feeding the moisture from inside.
Crack Pattern Review
We look at whether cracking follows a seasonal pattern consistent with clay soil movement or points to an active water source.
How it works
What to Expect
Tell us what you're seeing: a damp basement wall, a new crack, or water intrusion after heavy rain.
We walk the perimeter, checking grading, downspouts, and any standing water patterns near the foundation.
Moisture meter readings at foundation walls and baseboards identify where water is entering.
Nearby supply and drain lines get tested to rule out or confirm a plumbing source.
We explain whether you're dealing with a drainage issue, a plumbing leak, or both, and what fixing each one involves.

Tools & methods
Tools We Use
Moisture Meter
Reads moisture levels in foundation walls and baseboards to pinpoint water entry points.
Digital Pressure Gauge
Tests nearby plumbing lines to rule in or out a pressurized leak source.
Grading Level
Confirms whether the slope around your foundation is directing water away from the house or toward it.
Infrared Camera
Identifies temperature differences from moisture behind foundation walls.

One of the most common and most fixable causes of foundation moisture we find in Stillwater.
Plumbing leaks saturating soil near footings
A slow leak near the foundation perimeter can look identical to a drainage problem until it's tested.
Seasonal cracking from clay soil movement
Not every crack means a leak. We help homeowners tell the difference so they're not chasing a plumbing problem that isn't there.

✓ VerifiedA slab leak is a pressurized water line leaking under your concrete floor. A foundation leak involves water reaching your foundation from an exterior source like drainage or grading, or from a plumbing line near the perimeter.
No. Stillwater's clay soil expands and contracts seasonally, which causes cracking on its own. We check whether a crack follows that seasonal pattern or points to an active water source.
Most foundation inspections run $200 to $550 depending on whether plumbing testing is included alongside the exterior and moisture assessment.
Yes. Water pooling against a foundation repeatedly softens clay soil unevenly, which is one of the more common causes of foundation movement we see in Stillwater.
