Keep Your Home Dry, Healthy & Energy-Efficient
Crawlspaces in Chicagoland homes are especially vulnerable to moisture, mold, pests, and structural damage — all of which can affect the comfort and safety of your entire home. Alpha Development Group provides professional crawlspace encapsulation services designed to seal, protect, and stabilize your foundation. Using high-quality vapor barriers, insulation, and drainage solutions, we transform damp, drafty crawlspaces into clean, dry, and energy-efficient spaces.
What Is Crawlspace Encapsulation?
Crawlspace encapsulation is the process of sealing the crawlspace with a durable vapor barrier and moisture control system. This creates a protective environment that prevents:
- Moisture intrusion
- Mold and mildew growth
- Cold drafts entering through the floor
- Structural damage caused by long-term humidity
- Pests and rodents
It’s one of the most effective ways to improve indoor air quality and overall home performance.
