Cause before contractorIs gutters & drainage the right next step?
Gutter, downspout and site-drainage work where roof runoff is saturating walls or foundations.
What DampDeck would askCheck discharge points, grading and whether downspouts move water far enough away from the foundation.
What to compare in a US quote
- Diagnosis: what evidence identifies the water or humidity source?
- Scope: exactly what materials, systems and areas are included?
- Licensing / permits: requirements vary by state and locality; verify what applies to the actual work.
- Drying / remediation: how will wet materials and hidden cavities be handled?
- Warranty: what is covered, excluded and dependent on maintenance?
Location recordSan Francisco, CA
DampDeck uses the supplied US geography plus a source-led state moisture profile. It does not invent city housing-stock or property-age claims.
US moisture contextMixed western climate context
This state spans materially different climate and elevation zones, so DampDeck avoids one statewide diagnosis. Use the local symptom pattern, season, rainfall, HVAC operation and building assembly to narrow the cause.

How to read this: this is state-level orientation, not a claim that every home in San Francisco has the same climate, construction or moisture risk. US states can span multiple climate regions. Diagnose the actual water pathway first.
