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.
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.
Full-service crawlspace and attic restoration from inspection to install.
We document the full condition of your crawlspace or attic — moisture, mold, pests, insulation, ductwork, and structure — before recommending anything.
Safe removal of rodent droppings, nests, and contaminated insulation, with full HEPA decontamination of the area.
When mold is present, we contain, remove, and treat affected materials following the same standards we use in finished living spaces.
Heavy-duty 6+ mil vapor barriers seal moisture from rising into the structure — sized, taped, and sealed to last.
We remove old, contaminated, or compressed insulation and install fresh, properly-rated insulation throughout.
Vent screens, sealed access doors, and improved airflow keep crawlspaces and attics dry between visits.
Predictable, transparent, and built to last.
Detailed walkthrough with full documentation and a clear written scope.
Removal of debris, old vapor barrier, contaminated insulation, and waste.
Targeted treatment when contamination is present.
Fresh vapor barrier sealed to walls and footings.
New insulation and improved airflow throughout the space.
Before/after documentation so you know exactly what was done.

These spaces affect everything you live in above them. A properly restored crawlspace and attic deliver real, lasting benefits across the rest of your home.

Clean Workmanship. Honest Reporting. Lasting Results.
We treat your crawlspace and attic like the foundation of a healthy home — because they are. Our crews bring the same discipline to vapor barriers and insulation that we bring to finished living rooms.
Every project starts with a real inspection and an honest scope. You'll see what we see, in photos and writing, before any work starts. No fear-selling. No vague promises.
And when the job is done, you get a complete photo report — before and after — so you have a permanent record of exactly what was installed under and above your home.
Real projects, real properties, real transformations from our team.



Crawlspace and attic work is its own discipline — and our team specializes in it.
You see what we see and pay only for what your home actually needs.
Detailed before/after reports for your records and resale value.
Quality materials and proper installation — not a quick patch job.
