Your home might be at risk for moisture damage, mold, and higher utility bills without proper crawl space encapsulation. At Vance Insulation & DryGuard Systems, we specialize in creating dry, energy-efficient, and healthy properties throughout Prince George, VA, and the surrounding areas.
Our expert crawl space encapsulation services provide lasting protection from moisture, pests, and structural damage, ensuring your home stays comfortable and safe. When you choose us, you're not only improving your property but also enhancing your quality of life with warmer floors, reduced allergens, and lower energy costs.
Our crawl space encapsulation service begins with a thorough clean-out of the area, followed by addressing any water, moisture, or humidity issues. We inspect for mold and treat it if necessary, then insulate the subfloor to improve energy efficiency. To control humidity in the long term, we either install a dehumidifier or condition the space with your existing HVAC system. If water intrusion is a concern, we’ll also install a sump pump to keep the space dry and protected.
The DryGuard system takes encapsulation a step further by creating a fully sealed and insulated crawl space. We install a thermal barrier using fiberglass insulation between the floor joists and apply a heavy-duty vapor barrier along the crawl space floor and up the foundation walls. All seams are sealed with 4-inch foundation tape, and vents are completely closed off to keep outside air and pests out. An Aprilaire dehumidifier with a built-in hygrometer is added to monitor and control humidity levels around the clock actively, keeping your crawl space dry, clean, and healthy year-round.
Encapsulating your crawl space is a comprehensive process that improves your home’s energy performance, durability, and indoor comfort from the ground up.
By sealing off moisture and potential mold sources, encapsulation helps support cleaner, healthier air throughout your home.
Our DryGuard Sealed Crawlspace system creates a thermal boundary and seals air leaks, allowing your HVAC system to operate more efficiently.
With the installation of a dedicated dehumidifier and airtight vapor barriers, we maintain balanced humidity levels that protect your home throughout the year.
We always begin by removing any standing water and addressing mold concerns to create a clean, dry foundation, then seal the space completely.
Encapsulation blocks off the damp, open areas that attract pests, creating a barrier that keeps insects and rodents out.
By controlling moisture and sealing out outside air, your crawl space stays dry, helping prevent wood rot, rust, and foundation issues over time.
Mold doesn’t stand a chance with our crawl space mold remediation service. We utilize specialized treatments, such as OxyPro Cleaner and Shockwave spray, to eliminate mold at its source and follow up with targeted solutions to prevent it from returning.
Depending on your crawl space needs, we offer vapor barrier installations ranging from 10–35 mil, with 20 mil being a customer favorite for long-term durability. After a thorough inspection, we’ll recommend the right barrier to keep moisture and mold out while fitting your budget and home design.
Moisture control starts with solid crawl space drainage. We install 4-inch drain tile systems and French drains that route water safely away from your foundation, using time-tested techniques and quality materials.
For homes prone to standing water, our sump pump installation service is the real MVP. We use heavy-duty Glentronics systems, installed at the ideal point in your crawl space based on grading and foundation layout.
A proper crawl space dehumidifier does more than just dry the air—it helps protect your home’s structure, air quality, and energy efficiency. We install high-performance AprilAire systems with smart sensors that kick on at 55% humidity, and we make sure everything’s wired and drained properly.
With our basement waterproofing service, we dig deep—literally. We remove the concrete down to the footer, install drain tile systems that lead to a sump pump, and apply fiberglass reinforced plastic board to the walls to channel water into the drain system.
When attic mold creeps in, we come in strong with targeted attic mold removal. After inspecting for moisture sources and visible damage, we apply fungicidal treatments, such as OxyPro Cleaner, and sanitize the affected areas.
Not every attic is the same, which is why we customize each attic insulation installation to fit your space and your comfort goals. From blown-in fiberglass to spray foam, we offer a full lineup of insulation types that help reduce energy bills and regulate temperatures year-round.
Attic ventilation and sealing is where insulation meets strategy. We seal air leaks around pipes, lights, and access points, and ensure proper airflow to regulate temperature and moisture levels.
When you’re building new, our new construction insulation gives your home a head start on comfort and efficiency. We install fiberglass, batt, spray foam, or blow-in options tailored to your home’s layout and R-value goals.
For homes that need a refresh, our retrofit insulation service is a game changer. Whether we’re drilling and filling exterior walls or topping off your attic, we make sure you’re getting the most out of your insulation.
Crawl space insulation plays a huge role in keeping your home comfortable and protected from ground-level moisture. We offer options such as fiberglass batts for subfloors, rigid foam boards, and closed-cell spray foam for foundation walls.
Spray foam insulation is the high-performance choice for homeowners who want serious thermal control. We specialize in closed-cell spray foam, which offers top-tier R-values and doubles as an air and moisture barrier.
Older homes or tricky wall cavities? Drill and fill insulation gets the job done without tearing things apart. We carefully drill, blow in dense-pack insulation, and patch up cleanly for a low-disruption upgrade that brings your comfort and efficiency levels up to modern standards.
We make insulation removal easy, whether it’s old, moldy, or just ineffective. Our team vacuums out loose-fill insulation and hauls away fiberglass batts, clearing the way for something better.
