Short answerInspectors look for water, moisture, mold, and wood damage, check that crawlspaces have a vapor barrier and reasonable ventilation and access, and test the sump pump if there is one. Common findings are missing or torn vapor barriers, standing water, damp insulation, and sump pumps without a proper discharge. Many fixes are moderate in cost.
What do inspectors check?
Walls and floors, the crawlspace floor and vapor barrier, insulation, framing, the sump pit and pump, and discharge lines.
What are the common findings?
- Torn or missing crawlspace vapor barrier.
- Standing water or damp soil.
- Fallen insulation, wood rot, or mold on framing.
- Sump pump without a check valve or discharging too close to the house.
- Blocked crawlspace access.
How serious is it?
Moisture management is usually moderate in cost. Rot, active water, and structural damage are serious.
What does it cost to fix?

|---|---|---|
| Crawlspace sump, basin, and vent fan | About $3,250 on a recent job | W |
