Crawlspace & Attic Restoration

Serving McMinnville, Salem, Portland and the entire Willamette Valley

Inspection · Cleanup · Vapor Barriers · Ventilation Upgrades

The hidden parts of your home affect everything you breathe and feel above. We clean, seal, and restore crawlspaces and attics so the rest of your house can stay dry, healthy, and efficient.

Out of Sight, Not Out of Mind

Healthier Homes Start in the Crawlspace and Attic

In Oregon's wet climate, crawlspaces and attics are where most homes quietly fail. Standing moisture, rotting vapor barriers, rodent waste, and old insulation feed mold growth, attract pests, and push the air quality in your living space lower than you'd expect.

Our team treats these hidden zones with the same care we give your finished spaces. We inspect, clean, decontaminate, seal, and ventilate — leaving your crawlspace or attic dry, clean, and built to support a healthier home for years.

Our Capabilities

What We Handle Below and Above

Full-service crawlspace and attic restoration from inspection to install.

Detailed Inspection

We document the full condition of your crawlspace or attic — moisture, mold, pests, insulation, ductwork, and structure — before recommending anything.

Rodent & Pest Cleanup

Safe removal of rodent droppings, nests, and contaminated insulation, with full HEPA decontamination of the area.

Mold Remediation

When mold is present, we contain, remove, and treat affected materials following the same standards we use in finished living spaces.

Vapor Barrier Installation

Heavy-duty 6+ mil vapor barriers seal moisture from rising into the structure — sized, taped, and sealed to last.

Insulation Replacement

We remove old, contaminated, or compressed insulation and install fresh, properly-rated insulation throughout.

Ventilation & Sealing

Vent screens, sealed access doors, and improved airflow keep crawlspaces and attics dry between visits.
