A Sartell 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 Sartell inspection service more than a visual walk-through.
FLIR infrared thermal cameras detect temperature differentials in structural surfaces — a wet wall cavity cools differently than a dry one during evaporation, making moisture migration visible as a thermal signature even behind intact drywall. Our Sartell inspection team uses thermal imaging as the primary tool for tracing water migration paths through wall systems, subfloor assemblies, and ceiling cavities, identifying affected areas before a single pin is driven into a wall.
Thermal imaging shows probable moisture — calibrated moisture meters confirm it. Our Sartell 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.
Every COS Water Damage Restoration Sartell water damage inspection produces a written report: affected area descriptions, thermal images with annotations, moisture meter readings at labeled sensor points, water category determination (Cat 1/2/3), and a recommended scope of work with priority sequencing. Reports are formatted to be useful to your insurance carrier, a remediation contractor, or a real estate transaction where water damage disclosure is at issue.
Our Sartell inspection service covers two distinct use cases that require slightly different approaches: pre-remediation inspection (mapping an active or recent water event for claim documentation and remediation scoping) and pre-purchase or post-remediation verification inspection (confirming whether previous water damage was properly remediated or whether current conditions indicate an ongoing or previous water problem). Both use the same instrument suite and produce the same written report format, but the findings are interpreted differently for each use case.
COS Water Damage Restoration's Sartell inspection team covers every structural assembly type, every common water migration path, and every inspection use case encountered in residential and commercial water damage situations in MN.
Active event inspection is the step that prevents under-scoped remediation and missed hidden damage.
Pre-purchase water damage inspections in Sartell are scheduled on the buyer's timeline and the written report is available for the transaction file.
Post-remediation verification is an independent assessment — not a rubber stamp.
Mold risk assessment in Sartell is distinct from air quality testing. We assess structural conditions and visible evidence — not air samples.
Below-grade moisture in Sartell properties is underdetected and underlies a significant portion of structural issues discovered later.
Our Sartell inspection reports are formatted to the documentation standards that insurance carriers use to evaluate water damage claims in MN.


Same-day scheduling available for active water events. Pre-purchase inspections booked on your transaction timeline.
Our Sartell inspector arrives with FLIR thermal camera, calibrated pin-type and non-penetrating moisture meters, and inspection documentation tools. The inspection begins with a thermal pass of all suspected affected areas, followed by direct meter readings at all thermally identified locations. Each reading is recorded at a labeled sensor point location on the floor plan.
After the on-site assessment, your Sartell inspector reviews the key findings with you — which areas are affected, what the readings indicate, what water category applies, and what remediation is indicated. If you have questions about specific readings or want to understand what a particular finding means, this is the conversation for it. The verbal review happens on-site.
Report delivered in the format your use case requires, within 48 hours of inspection.



"The thermal imaging session was what sold me on how a proper Sartell 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."
"We used the COS Water Damage Restoration Sartell inspection report to file a homeowner's claim for a water damage event. The adjuster reviewed the thermal image documentation and sensor point readings and approved the full remediation scope on first submission. The inspection report paid for itself many times over by eliminating the supplement process."
"The post-remediation verification inspection is what I most value. After our last Sartell 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."
