Water damage in Somerville properties rarely stays where it originated. It migrates through wall framing, saturates subfloor assemblies, moves along structural members, and collects in ceiling cavities — creating hidden moisture pockets that show no visible surface signs but create ideal conditions for mold growth within 48-72 hours. COS Water Damage Restoration's Somerville inspection team uses FLIR thermal imaging, calibrated pin-type and non-penetrating moisture meters, and systematic structural assessment protocols to map water migration through your property completely — before remediation begins or before you close on a purchase.
Here's what makes our Somerville 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 Somerville property.
Thermal imaging shows probable moisture — calibrated moisture meters confirm it. Our Somerville 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 Somerville 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 Somerville — contact us with your specific situation and our inspector will scope the right assessment.
Here are the specific inspection scenarios and assembly types our Somerville team handles.
Active event inspection is the step that prevents under-scoped remediation and missed hidden damage.
Real estate transactions in Somerville frequently involve properties with prior water events — disclosed and undisclosed. Our pre-purchase inspection uses thermal imaging and moisture meters to identify active moisture in structural assemblies, staining patterns consistent with prior water intrusion, and the condition of previous remediation. For Somerville buyers, this inspection provides either confidence that a disclosed water event was properly handled, or documentation that it was not — giving the buyer negotiating leverage and a clear picture of what additional remediation cost, if any, is warranted.
After a water damage remediation project is completed in a Somerville 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 Somerville post-remediation inspection produces a written verification report formatted for real estate and insurance use.
Mold risk assessment in Somerville is distinct from air quality testing. We assess structural conditions and visible evidence — not air samples.
Below-grade moisture in Somerville properties is underdetected and underlies a significant portion of structural issues discovered later.
Our Somerville inspection reports are formatted to the documentation standards that insurance carriers use to evaluate water damage claims in MA.


Call +1-844-499-0972 and describe your situation — active event, pre-purchase, post-remediation, mold concern, or insurance documentation. Our Somerville scheduler assigns the appropriate inspection type and confirms your appointment. Most Somerville residential inspections are available within 24-48 hours.
Our Somerville 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.
Report delivered in the format your use case requires, within 48 hours of inspection.



"We were purchasing a Somerville 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 Somerville 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 Somerville 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."
