Trust our experts for crawl space cleaning and insulation replacement services in Bellevue

Insulation Co delivers crawl space cleaning services to help you live a healthier life. Crawl spaces are prone to be dark, dirty, and damp, making them susceptible to moisture-related issues such as mold, rot, and termite infestations. Poorly maintained crawl spaces can have damaged insulation, pest infestation, and structural damage. Damaged insulation can let in outdoor elements, such as summer heat and winter cold. Allergens can mix into your home’s indoor air, increasing the risk of health issues. Insulation Co’s crawl space cleaners inspect mold growth, pollutants, and signs of moisture damage. We have over 25 years of experience, and each crew leader has ten years of experience. You are in safe hands; we do a thorough crawl space clean-up every time.

DEBRIS removal

Crawl spaces may become clogged with debris limiting access for cleaning or repairs. Our crawl space clean-out inspection starts with removing all debris and junk.

mold remediation

After junk removal, organisms growing on surfaces such as mold and mildew require removal. Mold can be dangerous, and some variations are hard to see. We use a special spray compound to remove mold. This is not included in the crawl space clean out but we do offer this service for an extra charge!


The awful odor in your home may be dead animals in the crawl space. We safely dispose of any animal droppings and carcasses. Specially formulated sanitizing and deodorizing sprays remove excess contaminants.


A crawl space’s insulation can serve as a breeding ground for pests, which chew and damage the insulation. Before sealing up the crawl space, we will remove any damaged or torn materials.

VAPOR BARRIER installation

Moisture naturally rises into a house, affecting wood, insulation, and drywall. We can install a vapor barrier to protect your home. A vapor barrier creates a formidable barrier against mold.
