When this service is useful
Useful when a persistent musty odor or moisture pattern has no obvious visible source. The investigation narrows likely areas without promising that every concealed space can be assessed.
What the service involves
- 1Narrow the target using history, visual inspection, and moisture tools.
- 2Discuss access and the limits of the proposed method.
- 3Collect a cavity air sample or inspect through an existing access point when appropriate.
- 4Relate findings to surrounding materials and conditions.
What findings can and cannot establish
One cavity location cannot represent every concealed space. Creating an opening requires property authorization and may not be appropriate when utilities or hazardous materials could be present.
What you can expect to receive
- Target-location documentation
- Description of the access or sampling method
- Findings limited to the investigated cavity
- Recommendations for any broader evaluation
Scope, timing, and pricing factors
A responsible scope depends on the property and question. Factors that can affect the visit include:
- Number and location of target cavities
- Safe and authorized access
- Wall construction
- Whether non-invasive evidence is already sufficient
