- Illustrative figures shown until Q3 2026 dataset publishes.
- How the study works
A four-step research pipeline.
From voluntary, consented surveys to publication, every stage is documented, reviewed, and aggregated to county or ZIP level — never below.
- 01
Data collection
Voluntary phone-based surveys with documented consent. No personal data stored on public platforms.
- 02
Anonymization
All individual responses stripped of PII before aggregation. Minimum thresholds prevent re-identification.
- 03
Aggregation
Data combined at county / ZIP level. Statistical summaries replace individual data points.
- 04
Publication
Advisory board reviews all public data releases. Standard disclaimers on every visualization.
- Headline Insights
Three patterns we’re tracking.
Drawn from aggregated 2026 study data. Full methodology and confidence intervals will be available in the research section once the annual aggregate is published.
Home age
2.4×
Pre-1980 homes are 2.4× more likely to report moisture issues than post-2000 builds in the same county.
Climate shift
67%
Post-drought regions report new moisture within 18 months of return-to-normal precipitation cycles.
Maintenance
78%
Untreated basements show progressive deterioration signals across consecutive seasonal observations.
