Start with access and moisture conditions
The original service offering includes crawl space and attic sanitation for mold and mildew, along with replacing fallen insulation. The right scope depends on what materials are affected and whether the source is groundwater, humidity, a plumbing leak or another issue.
Discuss cleaning and material replacement
Ask which surfaces can be cleaned, which materials may need removal and how work areas will be handled. The scope should distinguish sanitation from waterproofing and explain whether insulation replacement is included. Extensive contamination or other hazards may require a specialist assessment.
Pair sanitation with water management
If water continues entering the space, newly installed materials can become wet again. Review drainage and foundation concerns alongside the sanitation work. A dry-looking surface on the day of inspection does not rule out recurring rain-related problems.
Prepare without disturbing materials
Describe odors, visible growth, fallen insulation and any known leak history on the call. Share photos only if they can be taken safely. Avoid disturbing suspect materials or entering a confined, flooded or electrically unsafe space.
