Stop Moisture & Mold Growth with Professional Crawl Space Cleaning
Your crawl space plays a bigger role in your home’s comfort and health than most homeowners realize. In the damp climate of the Pacific Northwest, crawl spaces are especially vulnerable to moisture, mold growth, and poor air circulation. At Northwest Weatherization, we provide professional crawl space cleaning in Portland, OR, helping local homeowners protect their property, improve indoor air quality, and breathe easier year-round.
What’s Included in Our Crawl Space Cleaning Services
Our clean up services are thorough, detailed, and tailored to the needs of homes throughout the Portland metro area. Every home is different, but our high quality service typically includes:

- Safe removal of rodent droppings and nesting materials
- Addressing moisture issues that contribute to mold growth
- Cleaning and sanitizing affected surfaces with enzymatic solutions
