When Should You Get Crawl Space Encapsulation?
Many homeowners don’t give their crawl space much thought until something goes wrong. So, if you are dealing with moisture, pests, and structural shifts, you might want to check your crawl space.
High Humidity
When humidity levels in your crawl space rise, they create the perfect environment for mold, mildew, and wood rot. This can lead to a host of indoor air quality problems. If your home feels damp or stuffy, your crawl space may be to blame.
Mold or Mildew
Mold in your crawl space does not just stay there. It spreads quickly and can trigger allergies or respiratory problems inside your home if you smell a musty odor or see mold on baseboards, walls, or vents. It’s time to investigate your crawl space.
Standing Water
Water in your crawl space is a major red flag. It could be caused by a plumbing leak or poor drainage, and the standing water will damage insulation, weaken support structures, and attract pests. Encapsulation keeps water out and helps redirect it away from your foundation.
Structural Damage
A neglected crawl space can compromise the stability of your entire home. Rotten wood, sagging beams, or uneven floors are signs that moisture has already taken a toll. Encapsulation paired with structural repairs can restore its strength and help prevent further issues.
Increased Energy Bills
Crawl spaces often let cold air in during the winter and hot air in during the summer. That means your HVAC system has to work harder to maintain a comfortable temperature. Encapsulation seals gaps and improves insulation, leading to lowered energy use.
Foundation Cracks or Shifting
Moisture beneath your home can cause the soil to shift, putting stress on your foundation. Different sizes of cracks in your walls or around windows and doors are often a symptom of this. By keeping your crawl space away from water, you can protect your entire home’s structure.
