A Mount Vernon 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 Mount Vernon 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 Mount Vernon 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 Mount Vernon 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 Mount Vernon — contact us with your specific situation and our inspector will scope the right assessment.
Here are the specific inspection scenarios and assembly types our Mount Vernon team handles.
Active event inspection is the step that prevents under-scoped remediation and missed hidden damage.
Pre-purchase water damage inspections in Mount Vernon 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 Mount Vernon 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 Mount Vernon post-remediation inspection produces a written verification report formatted for real estate and insurance use.
Properties in Mount Vernon 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 Mount Vernon properties — crawlspaces, basement areas, and below-slab conditions — are among the most common locations for chronic moisture problems to go undetected. Our Mount Vernon 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 Mount Vernon inspection reports are formatted to the documentation standards that insurance carriers use to evaluate water damage claims in SD.


Same-day scheduling available for active water events. Pre-purchase inspections booked on your transaction timeline.
Our Mount Vernon 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.
You understand what was found before you receive the written report.
The written inspection report — thermal images with annotations, sensor point readings mapped to a floor plan, water category determination, and recommended scope — is delivered within 24-48 hours of the on-site session, formatted for insurance, remediation, or real estate use as appropriate to your situation. We're available to answer adjuster or real estate agent questions about the findings.



"We were purchasing a Mount Vernon home where the seller had disclosed a prior basement water event and claimed it was fully remediated. COS Water Damage Restoration's pre-purchase inspection found moisture readings in the wall framing adjacent to the original event area that were significantly above dry standard — indicating incomplete drying. The written report we received gave us specific sensor point readings that we used to negotiate remediation credit from the seller before closing. Without that inspection, we would have closed into a mold problem."
"I had noticed a musty smell in a room of my Mount Vernon 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."
"We manage a portfolio of Mount Vernon rental properties and COS Water Damage Restoration's inspection service is what we use every time a water event is reported, prior to any remediation starting. The inspection report maps the damage completely — it's what we give our remediation contractor as the scope of work and what we give our insurer as the damage documentation. Having a consistent, instrument-backed inspection process has eliminated the disputes we used to have about whether remediation was complete or whether the damage scope matched what we claimed."
