A crawl-space odor reduced after roof drainage was redirected
The indoor odor tracked long rain events because a downpipe discharged beside the foundation and raised crawl-space humidity.
✓Measurement Supportedrecorded confirmation level
01 / OBSERVED
→Earthy odor on the ground floor after prolonged rain
02 / CONFIRMED CAUSE
→Roof water discharging beside a vented crawl space
03 / REPAIR
→The downpipe was extended, grading corrected and crawl-space moisture monitored.
04 / VERIFY
Peak humidity declined and the odor did not return at previous intensity.
