Crawl space encapsulation in Seattle
Water is your crawl space’s worst enemy. Without humidity control, it can lead to big problems in the rest of your home. If mold grows, the air quality can be polluted, and wood support beams can deteriorate. In the Seattle area, we’re no strangers to humidity. We recommend having your crawl space checked annually, especially if you don’t see signs of an unhealthy crawl space.
Signs of excess humidity
High indoor humidity is more than just an annoyance; it could be telling you that you have crawl space condensation and moisture problems. This is not something to neglect. Mold spores in your home’s air can trigger negative health symptoms and even structural failure. If you see any of these signs, it’s time to schedule an inspection:
- Musty odors in your home
- Sloping or warped wood floors
- Deteriorating or wet wood in basement
- Visible moisture in basement or on foundation
- Allergy-like symptoms with no known allergen present
