A Castell 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 Castell 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.
Thermal imaging is non-destructive and covers large surface areas quickly — making it the most efficient way to map water migration in a Castell property.
Thermal imaging shows probable moisture — calibrated moisture meters confirm it. Our Castell 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 Castell 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 Castell — contact us with your specific situation and our inspector will scope the right assessment.
COS Water Damage Restoration's Castell 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 TX.
When a water damage event has just occurred in a Castell 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 Castell 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 Castell 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 Castell 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 Castell post-remediation inspection produces a written verification report formatted for real estate and insurance use.
Mold risk assessment in Castell is distinct from air quality testing. We assess structural conditions and visible evidence — not air samples.
Below-grade spaces in Castell properties — crawlspaces, basement areas, and below-slab conditions — are among the most common locations for chronic moisture problems to go undetected. Our Castell 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 Castell inspection reports are formatted to the documentation standards that insurance carriers use to evaluate water damage claims in TX.


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.
After the on-site assessment, your Castell 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 Castell 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 Castell 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 Castell 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."
