Full-Area Moisture Mapping
We take multiple readings across walls, floors, or crawlspaces to build a pattern rather than relying on one spot check.
Moisture that's already visible is moisture that's been building for a while. We map it before it gets there, using meters and infrared imaging to see what's happening inside walls, under flooring, and in crawlspaces most Stillwater homes never look at.

One moisture reading tells you there's a problem. A map tells you how far it's spread and where it's coming from. We take readings across an entire wall, floor, or crawlspace and record them as a pattern, not just a single number, because the pattern is what points back to the source.
Crawlspaces are a common blind spot in older Stillwater homes, especially those without a modern vapor barrier. Humidity trapped there condenses on cool surfaces and, over years, feeds mold growth and wood rot that homeowners often don't discover until it reaches the subfloor.
We look at the whole pattern, not just the spot you noticed.

Shows temperature differences that indicate moisture behind drywall, flooring, or ceilings without opening anything up.
Two of the most common places moisture builds unnoticed in older Stillwater homes, especially those without a vapor barrier.
We don't stop at confirming moisture is present. We work to trace it back to a leak, condensation, or ventilation issue.
Tell us what's prompting the concern, a musty smell, visible staining, or a known past leak you want checked.
We take baseline readings across the area of concern to establish where moisture levels are elevated.
Thermal imaging extends the survey behind walls and under flooring without any cutting or drilling.
If accessible, we check these areas directly, since they're common sources of hidden moisture.
We present the moisture map and explain the likely source, along with next steps.

Used together to get both surface and subsurface moisture readings without unnecessary drilling.
Extends detection behind finished surfaces by reading temperature differences caused by moisture.
Measures relative humidity in crawlspaces and attics, useful for identifying condensation risk even without an active leak.
A small camera that can inspect inside a wall cavity through a minimal access point when needed.

A homeowner near Washington St and Hall of Fame Ave noticed a musty smell in the living room with no visible water.
After: Crawlspace inspection found high humidity and no vapor barrier. Moisture mapping confirmed it was condensation-driven, not a leak, and pointed to a ventilation fix.

A landlord near Knoblock Street had a tenant report a ceiling stain that reappeared after every rain.
After: Infrared scanning traced the moisture path from a roof flashing failure, not the plumbing the landlord had suspected.

A homeowner in College Gardens noticed peeling paint on an interior wall with no obvious cause.
After: Moisture mapping traced elevated readings back to a slow supply line leak two stud bays away from the visible damage.

Ask a pro →Common in older Stillwater homes and a steady contributor to mold risk even without an active leak.
A single water stain rarely marks the full extent of the problem underneath it.
Humidity and temperature differences can mimic leak symptoms, and mapping helps tell the two apart.
“Leak Radar's moisture detection service was thorough and professional. They found a hidden leak in my basement that saved me thousands in repairs!”

✓ Verified“I was impressed with the detailed report provided after the moisture inspection. It helped me understand the issues in my home and how to fix them.”
Emily R.Homeowner, College Gardens
✓ VerifiedMoisture mapping identifies where and how much water is present, which is often the root cause behind mold. We can flag areas that warrant a separate mold inspection if conditions suggest it.
In most cases yes, using moisture meters and infrared imaging. A borescope, which needs only a small access hole, covers the rest.
Most moisture mapping visits run $175 to $450 depending on the size of the area and whether crawlspace or attic access is involved.
Humidity rises. A crawlspace without a vapor barrier can be the actual source of moisture that shows up as a stain or smell a floor or two above it.
