Serving Adams, Cumberland, Dauphin, Franklin, Lancaster, Lebanon & York Counties
Crawl space encapsulation and insulation are smart, cost-effective ways to protect your home’s structure while improving comfort and energy efficiency. By sealing off your crawl space and adding high-performance insulation, you reduce moisture, prevent mold, and lower your energy bills.
Properly insulating your crawl space also eliminates cold drafts from below — keeping your floors warmer in winter and your home more comfortable year-round. Our experienced crawl space team assesses your space and recommends the best approach to keep your home dry, efficient, and cozy.
Up to half the air you breathe upstairs starts in the crawl space — sealing it out protects your comfort, health, and home.
A durable vapor barrier blocks ground moisture and humidity — preventing mold, mildew, and wood rot while improving the air quality throughout your home.
Sealing air leaks and insulating the crawl space ends cold drafts from below and helps your HVAC run more efficiently — cutting your heating and cooling costs.
Controlling moisture protects your foundation, beams, and floor joists from rot and corrosion — and helps block entry points for rodents, insects, and other pests.
Both improve your home’s comfort, energy efficiency, and air quality — and we specialize in both. The terms are often used together, but they describe two distinct processes. Here’s how they compare, and why many Central PA homes benefit from a combination of the two.
Focuses on temperature control — fiberglass batts or spray foam installed along the crawl space walls or subfloor, tailored to vented or unvented spaces. Reduces cold floors and improves HVAC efficiency.
Seals and protects the entire space — a vapor barrier over floors and walls, sealed vents and air leaks, and optional dehumidifiers. Targets moisture, mold, pests, and long-term structural protection.
Many homeowners get the best results from both. We’ll assess your space and recommend the most effective solution based on your home, local climate, and crawl space condition. Explore our other insulation services →
