What needs assessment
A cool patch can have several explanations, including airflow, insulation differences, or evaporation. Ask whether the provider will confirm suspected wet areas with suitable measurements or access. Images should be tied to room locations and the water event.
Three points to discuss
- Image location
- Other causes of temperature change
- Moisture confirmation
Drying and material decisions
Use the camera as one inspection tool rather than a complete clearance method. A thermal image alone should not determine demolition or drying completion. Ask which observations are confirmed and which remain investigative clues.
Property context
Planning the work in San Antonio
For San Antonio drying, ask how the provider will reach moisture in concealed floor or wall layers and verify the endpoint. HVAC source repairs and restoration drying are separate tasks. Where outside entry occurred, the city’s hydrologic or regional flood resources can support later drainage review alongside the building work.
San Antonio provides development and hydrologic-feature maps, and its flood-preparation guide directs property owners to regional floodplain information. Use the property address to review creek or drainage context. An indoor leak, roof opening, and runoff entry can require different source work even when the affected room looks similar.
Questions about this work
Can a thermal camera prove that a wall is wet?
No. It shows temperature differences; moisture needs confirmation using an appropriate method.
What should I prepare before calling about this work in San Antonio?
Give the exact address, the suspected source, the discovery time, affected rooms or levels, source repairs already completed, and any safety or access restrictions. Ask the responding provider to confirm current availability and the proposed initial scope.
How will I know when the affected materials are ready for repairs?
Ask for the final moisture or condition findings and the reasons supporting drying completion, cleaning, or removal. Any source problem or inaccessible area should be explained before finishes conceal the assembly again.
