A Sunol 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.
A credible water damage inspection in Sunol does more than identify where the water is visible. It traces where the water went — through structural assemblies, behind finishes, and into below-grade spaces — and produces a written, defensible assessment you can act on or present to an insurance carrier, a buyer, or a remediation contractor.
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 Sunol 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.
Qualitative assessment says "it looks wet." Quantified readings say "this framing is at 28% moisture content and the dry standard is 10%."
Every COS Water Damage Restoration Sunol 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.
Both use cases are available in Sunol — contact us with your specific situation and our inspector will scope the right assessment.
COS Water Damage Restoration's Sunol 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 CA.
Active event inspection is the step that prevents under-scoped remediation and missed hidden damage.
Pre-purchase water damage inspections in Sunol 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 Sunol 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 Sunol post-remediation inspection produces a written verification report formatted for real estate and insurance use.
Mold risk assessment in Sunol is distinct from air quality testing. We assess structural conditions and visible evidence — not air samples.
Below-grade moisture in Sunol properties is underdetected and underlies a significant portion of structural issues discovered later.
Our Sunol inspection reports are formatted to the documentation standards that insurance carriers use to evaluate water damage claims in CA.


Same-day scheduling available for active water events. Pre-purchase inspections booked on your transaction timeline.
Systematic, instrument-driven, fully documented during the on-site session.
You understand what was found before you receive the written report.
Report delivered in the format your use case requires, within 48 hours of inspection.



"We were purchasing a Sunol 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."
"We used the COS Water Damage Restoration Sunol 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 Sunol 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."
