Even with good insulation above, an unsealed crawl space lets in cold air and wastes heat. Our weatherization process seals gaps, insulates exposed areas, and adds vapor protection—helping you save energy and stay comfortable year-round. Contact us today to get started!
what Crawl Space Weatherization is and what it includes
Air Sealing
We seal gaps, cracks, and holes around plumbing, wiring, vents, and joists to prevent outside air from entering and conditioned air from escaping—improving energy efficiency
Insulation Installation
High-performance insulation is added or upgraded beneath the floor to reduce heat loss, stop drafts, and help maintain consistent indoor temperatures
Vapor Barrier Installation
We install a heavy-duty vapor barrier over the crawl space ground to block ground moisture, reduce humidity, and help prevent mold, mildew, and rot
Rodent & Pest Exclusion
Once the contract is signed, payment is due upon job completion. We offer three financing options to make the service more affordable
Moisture & Mold Prevention
By controlling airflow and ground moisture, crawl space weatherization protects your home from mold growth and water-related damage
Lower Energy Bills
Sealing gaps and insulating your crawl space prevents heat loss and reduces drafts, helping your HVAC system run more efficiently and cutting monthly energy costs.
Improve Indoor Comfort
Proper weatherization keeps your home warmer in winter and cooler in summer, eliminating cold floors and inconsistent temperatures.
Protect Against Moisture & Mold
Adding a vapor barrier and sealing air leaks helps keep moisture out, reducing the risk of mold growth, wood rot, and structural damage.
Enhance Air Quality & Health
Since up to 50% of your home’s air comes from the crawl space, sealing it improves indoor air quality, reducing dust, allergens, and pollutants.

Our trained and certified technicians handle everything—from inspection and insulation to sealing and cleanup. With one service visit, we can transform your crawl space into a sealed, energy-efficient barrier that supports your home’s comfort and structure.
