A Frontenac water damage inspection isn't a walk-through with a flashlight. It's a systematic, instrument-driven assessment that produces a written report showing exactly where the water went, how saturated each affected assembly is, and what needs to happen next.
Here's what makes our Frontenac inspection service more than a visual walk-through.
Thermal imaging is non-destructive and covers large surface areas quickly — making it the most efficient way to map water migration in a Frontenac property.
Thermal imaging shows probable moisture — calibrated moisture meters confirm it. Our Frontenac inspectors use both pin-type meters (direct reading in framing and structural members) and non-penetrating radio-frequency meters (surface reading through drywall and flooring) to take quantified moisture content readings at all thermal-identified locations. These readings are recorded at labeled sensor points and become the data basis for the written inspection report.
A verbal assessment is an opinion. A written report with instrument readings is documentation.
Both use cases are available in Frontenac — contact us with your specific situation and our inspector will scope the right assessment.
Here are the specific inspection scenarios and assembly types our Frontenac team handles.
When a water damage event has just occurred in a Frontenac property — or happened within the last several days — our inspection maps the full extent of saturation while the moisture is still detectable by thermal imaging and direct meter readings. This inspection is the foundation of the remediation scope and the insurance claim documentation. Without it, remediation crews are guessing at what to dry, and insurance carriers are estimating on incomplete data. Our Frontenac active event inspection captures the full saturation picture at the moment of peak detectable moisture — when the readings tell the most accurate story of what happened.
Pre-purchase water damage inspections in Frontenac are scheduled on the buyer's timeline and the written report is available for the transaction file.
After a water damage remediation project is completed in a Frontenac property — whether by COS Water Damage Restoration or another company — a verification inspection confirms that structural drying was completed to standard moisture content levels and that no hidden moisture was left behind. This inspection is requested by property owners who want independent confirmation of completion, by landlords who need documentation before returning a property to tenancy, and by sellers who need to demonstrate to a buyer that prior water damage was fully resolved. Our Frontenac post-remediation inspection produces a written verification report formatted for real estate and insurance use.
Properties in Frontenac that had a water event 48 hours or more before inspection — or where a slow leak went undetected for an extended period — may present mold risk alongside ongoing moisture concerns. Our mold risk assessment inspection identifies the structural conditions that support mold growth: elevated moisture content in organic materials, elevated ambient relative humidity, and the presence of visible mold growth on surface or semi-concealed areas. This assessment determines whether a standard drying-focused remediation is appropriate or whether S520-standard mold remediation protocols need to be incorporated into the project scope.
Below-grade spaces in Frontenac properties — crawlspaces, basement areas, and below-slab conditions — are among the most common locations for chronic moisture problems to go undetected. Our Frontenac below-grade inspection covers crawlspace wood framing moisture content readings at joists and beams, vapor barrier condition and coverage, condensation evidence on structural surfaces, and visual assessment for wood rot, fungal growth, and pest damage associated with chronic moisture. Written findings document the below-grade condition for remediation scoping or real estate disclosure.
Our Frontenac inspection reports are formatted to the documentation standards that insurance carriers use to evaluate water damage claims in MN.

"The thermal imaging session was what sold me on how a proper Frontenac water damage inspection should work. Our inspector traced water migration I never could have guessed at — the event in the utility room had spread moisture into the adjacent storage room wall framing more than twelve feet away. The written report documented all of it and our remediation contractor used it directly to scope the drying project."
"I had noticed a musty smell in a room of my Frontenac home for months before calling COS Water Damage Restoration. Their inspection found active moisture in the subfloor assembly under an area rug — a slow pipe drip that had been going on long enough to saturate the subfloor significantly without any visible surface evidence. The written report documented the moisture readings, the thermal images showing the extent of the affected area, and the recommended scope. I would never have found this without the thermal camera."
"The post-remediation verification inspection is what I most value. After our last Frontenac property water event, the remediation contractor signed off on completion. We had COS Water Damage Restoration do a verification inspection and found one wall section with framing still above 15% moisture content. That section would have been a mold problem within weeks. The verification inspection caught it before it became our problem."
