Healthy Homes for Oregon — Marine Damp, Smoke Season, Cascadia
Virtual Home Health Score assessments on both sides of the Cascades. GaiaCrete™ detailed for Oregon's specialty energy code and marine climate. Founding Mr Hemp House® dealer territories open by ZIP code.
Persistent marine rain and mold
Western Oregon's long wet season keeps walls and crawlspaces damp for months, and mold grows without any dramatic leak event.
Annual wildfire smoke
Oregon smoke episodes now recur every late summer, pushing hazardous particulate into homes with no filtration plan.
Cascadia seismic exposure
Oregon sits above the Cascadia subduction zone, so structural and non-structural bracing requirements shape how walls are built.
What Climate Zone 4C-5B Means for Oregon Homes
Oregon splits sharply at the Cascades: a marine Zone 4C west side with eight months of rain, and a dry Zone 5B-6B high desert east. West-side homes fight persistent low-grade moisture and mold rather than dramatic weather. Statewide, late-summer wildfire smoke has become an annual indoor air event, and Oregon's energy code is among the more demanding in the country.
Oregon Residential Specialty Code and Oregon Energy Efficiency Specialty Code
Oregon writes its own specialty codes based on the I-Codes, with energy requirements stricter than the base IECC.

Home Health Score
A free screening that scores your home across indoor air quality, moisture and mold risk, building materials, and ventilation — so you know where to look first.
Healthy Home Assessment
A professional walkthrough of materials, moisture conditions, and ventilation, delivered as a prioritized action plan. Screening and guidance — not a medical or diagnostic service.

Actual thermal performance varies by formulation, density, moisture content, installation method, and complete wall assembly. Final whole-wall thermal performance depends on the complete assembly, including material density, framing, finishes, thermal bridging, moisture conditions, and installation.
