Vance Insulation & DryGuard Systems has been proudly serving Prince George, VA, and its surrounding communities for over six decades. Founded in 1962 by Harold Vance (known to many as HB), a dedicated military veteran from Southwest Virginia, the company grew into a trusted, family-owned staple of the Greater Richmond area.
Passed down through generations, Vance Insulation & DryGuard Systems continues to thrive under the leadership of Harold's son, Robbie Vance, alongside his cousin, Jeff. Built on a commitment to exceptional quality, unwavering integrity, and expert workmanship, we’ve dedicated ourselves to keeping homes and commercial properties comfortable and energy-efficient.
From crawl spaces to comprehensive insulation solutions, we’ve helped countless property owners across the region save energy and enhance their living spaces.
At Vance Insulation & DryGuard Systems, we take crawl space encapsulation seriously—cleaning, sealing, insulating, and installing dehumidifiers or sump pumps as needed. Our DryGuard sealed crawlspace system adds a full thermal boundary and includes 24/7 humidity control for year-round protection.
Our crawl space mold remediation addresses mold at its source using professional-grade treatments, including Shockwave spray and OxyPro Cleaner. Our team understands that without a dry crawl space, mold will inevitably return. Therefore, we ensure your space remains dry and mold-free long after we complete the job.
Nothing beats a solid moisture defense, and that starts with a proper crawl space vapor barrier. We offer 10–35 mil options, and our 10–16 mil liners are especially popular with Virginia homeowners seeking durable, long-lasting protection.
Our crawl space drainage systems include French drains and drain tile installations designed to move water away before it becomes a problem. We're the crawl space contractor who gets it right the first time, preventing moisture buildup from the ground up.
We install heavy-duty sump pump systems using Glentronics cast iron pumps for maximum performance. From wiring to water control, we handle the full setup—reliable, code-compliant, and built to last.
When it comes to crawl space dehumidifier installation, we don’t cut corners. We work with certified electricians to ensure the AprilAire brand systems we install run smoothly with proper power and monitoring, keeping humidity levels where they should be.
Basement waterproofing is all about smart drainage and sealed surfaces. We install drain tile, sump pumps, and fibre-reinforced plastic wall panels that channel water away fast.
Our attic mold removal services involve using OxyPro Cleaner and a thorough sanitization process. We eliminate black mold, clean the space, and create conditions that help prevent it from coming back.
Our attic insulation installation services feature blown-in insulation—an efficient and effective solution that helps regulate indoor temperatures and lower energy bills. Whether you're insulating a new home or upgrading an existing attic, we’ll ensure your space is properly sealed and meets modern energy standards.
Good airflow and tight seals go hand in hand. Our attic ventilation and sealing services will seal all cracks and penetrations in your ceiling, keeping indoor air where it belongs.
We work with homeowners and builders to install fiberglass, blow-in, batt, or closed-cell spray foam insulation in new construction projects. It’s all about creating energy-smart homes from the ground up.
Bringing older spaces up to modern standards is what retrofit insulation is all about. From attics to storage areas, we upgrade insulation levels to make homes more comfortable and energy-efficient.
Insulating a crawl space isn’t a one-size-fits-all job, and we approach each one with care. We install fiberglass between joists and rigid foam board on foundation walls to create a tight thermal envelope.
Our closed-cell spray foam insulation provides air sealing and moisture resistance in one powerful application. Whether on attic roof decks or crawl space walls, it delivers long-term efficiency.
We improve insulation in existing walls with our drill and fill method, using loose-fill insulation to close gaps without major disruption. It’s a smart upgrade with real results.
Insulation removal is one of those jobs that’s best left to folks who do it every day, and that’s us. We’ll handle everything from vacuuming out messy loose-fill insulation to hauling away worn-out fiberglass batts.
We honor our military, veterans, and first responders with a 5% discount on all services.
We’ve been a family-operated business since our inception, dedicated to upholding local values and providing personalized service.
Flexible payment options are offered through GreenSky to make your project stress-free.
We provide no-obligation inspections to help you plan your project.
