Your floors stop feeling cold in winter. That musty smell disappears. Your energy bills drop by 15-20% annually because conditioned air isn’t escaping through an open crawl space anymore.
You’re not dealing with mold concerns or wondering if moisture is rotting the floor joists under your feet. The air coming up into your home—and about 40% of your indoor air does come from the crawl space—is clean instead of carrying spores, allergens, and whatever else is growing down there.
Your HVAC system isn’t working overtime to heat or cool air that’s being pulled through vents in an unsealed space. That means lower monthly bills and equipment that lasts longer. You’ve also eliminated the damp environment that attracts pests like termites, roaches, and rodents.
Encapsulation turns your crawl space into controlled space. Dry, protected, and no longer a liability.
We’ve spent over 30 years improving indoor air quality for homeowners across Guilford, Randolph, Alamance, and Forsyth Counties. We’re NADCA certified, and our crawl space encapsulation systems come with a lifetime warranty.
We’re not new to North Carolina’s climate challenges. The humid subtropical conditions here create perfect environments for moisture problems, and we’ve seen what happens when crawl spaces go untreated. Mold growth, wood deterioration, pest infestations, and skyrocketing energy costs.
Vandalia homeowners deal with the same humidity issues affecting the rest of the Piedmont Triad region. We understand the local conditions because we’ve been working in them for decades. When you call us, you’re talking to people who’ve encapsulated hundreds of crawl spaces and know exactly what your home is up against.
We start with a thorough crawl space inspection. We’re looking at moisture levels, existing damage, ventilation issues, insulation condition, and what’s causing the problems you’re experiencing. You get a clear explanation of what we find and what needs to happen.
Next comes crawl space cleaning if needed. Any standing water, debris, damaged insulation, or mold gets addressed before encapsulation begins. You can’t seal a crawl space that’s already compromised.
Then we install the vapor barrier—a heavy-duty liner that covers the floor and walls, sealing out ground moisture. We seal all vents and openings that were letting in humid outside air. If your crawl space needs a dehumidifier installation to maintain proper humidity levels year-round, we’ll recommend and install the right system.
We also handle crawl space insulation if your rim joists or walls need it. The goal is complete moisture control and thermal protection. When we’re done, your crawl space is a sealed, conditioned part of your home instead of an open pit pulling in humidity and pushing out your money.
Ready to get started?
A proper crawl space encapsulation isn’t just throwing down plastic sheeting. You’re getting a professionally installed vapor barrier that’s sealed at every seam, wrapped up the walls, and secured to prevent any ground moisture from entering your crawl space.
All foundation vents get sealed permanently. Those vents were designed for a different era of building science—we now know that ventilating a crawl space with humid North Carolina air in summer just makes moisture problems worse. Sealing them is critical.
Dehumidifier installation keeps relative humidity below 60%, which is the threshold where mold starts growing and wood begins to rot. In Vandalia’s climate, a dehumidifier isn’t optional if you want long-term moisture control. It’s the difference between a system that works and one that fails in July.
You also get insulation work where needed, vent sealing, and moisture remediation if there’s existing damage. The system we install is designed specifically for the conditions your home faces—not a one-size-fits-all approach. We’ve been doing this long enough to know what works in this region and what doesn’t.
Most crawl space encapsulation projects in the Vandalia area run between $3,500 and $15,000 depending on the size of your crawl space, the condition we’re starting with, and what additional work is needed. A straightforward encapsulation on a 1,200-square-foot crawl space with minimal prep work will cost less than a larger space that needs mold remediation, structural repairs, or drainage solutions first.
The price includes vapor barrier installation, vent sealing, dehumidifier installation if needed, and any insulation work. We give you a clear quote after the inspection so there’s no guessing. The investment typically pays for itself over time through energy savings—most homeowners see 15-20% reductions in heating and cooling costs, which adds up to $300-$400 annually for an average-sized home.
You’re also avoiding much bigger expenses down the road. Wood rot repairs, foundation work, mold remediation, and HVAC replacements all cost significantly more than encapsulation. It’s cheaper to prevent the damage than fix it later.
Yes. Field studies consistently show 15-20% annual savings on heating and cooling costs after crawl space encapsulation. That’s not marketing talk—it’s what happens when you stop conditioned air from escaping and unconditioned air from entering your home through an unsealed crawl space.
The “stack effect” is working against you right now. Warm air rises and escapes through your attic, which pulls replacement air up from the crawl space. If that crawl space is full of cold winter air or hot humid summer air, your HVAC system is constantly fighting to condition it. Seal the crawl space, and you’ve stopped the cycle.
Your HVAC system also runs less frequently because it’s not trying to overcome constant temperature and humidity swings from below. Less runtime means lower utility bills and longer equipment life. For a typical 2,000-square-foot home in Vandalia, you’re looking at keeping $300-$400 in your pocket every year. Over a decade, that’s real money.
A professionally installed crawl space encapsulation system lasts decades when done correctly. The vapor barrier itself is a heavy-duty material designed for long-term ground contact, and when it’s properly sealed and maintained, it doesn’t break down. Our systems come with a lifetime warranty because we’re confident in what we’re installing.
The dehumidifier is the only component that may need replacement eventually, similar to any other appliance. Most crawl space dehumidifiers run for 10-15 years before needing replacement, and even then, the encapsulation system itself is still fully functional.
The key is proper installation from the start. Cheap vapor barriers that aren’t sealed correctly or systems installed without addressing underlying drainage issues will fail faster. We’ve been doing this for over 30 years, and we’ve seen what lasts and what doesn’t. When we encapsulate your crawl space, it’s staying encapsulated.
In North Carolina’s climate, yes. Encapsulation stops ground moisture and outside air from entering, but you still need active humidity control to keep levels below 60% year-round. That’s especially true during our humid summer months when even a sealed crawl space can see humidity creep up without a dehumidifier running.
Relative humidity above 60% is when mold growth starts and wood rot accelerates. A dehumidifier installation ensures your crawl space stays in the safe zone regardless of what’s happening outside. It’s a small ongoing cost—most units pull 2-3 amps and cost $15-$30 monthly to run—but it’s what makes the entire system work long-term.
Some companies will try to sell you encapsulation without a dehumidifier to lower the upfront price. That’s a mistake in this region. You’ll end up with moisture problems anyway, and you’ve wasted money on a system that isn’t complete. We install dehumidifiers as part of the encapsulation process because we know what Vandalia’s climate requires.
Encapsulation prevents future mold growth by eliminating the moisture mold needs to survive, but existing mold has to be remediated first. You can’t seal mold into your crawl space and expect good results. We address any active mold during the crawl space cleaning phase before the vapor barrier goes down.
Mold remediation involves removing contaminated materials, treating affected surfaces, and ensuring the space is clean before encapsulation begins. Once the crawl space is sealed and humidity is controlled below 60%, mold can’t grow back. It’s a permanent solution, but only if the existing problem is handled correctly first.
If you’re seeing mold, smelling musty odors, or dealing with allergy symptoms that seem worse at home, your crawl space is likely the source. About 40% of the air in your home originates from the crawl space, so whatever’s growing down there is coming upstairs. Encapsulation stops that cycle, but remediation has to come first.
Most crawl space encapsulation projects take 1-3 days depending on the size of the space and the scope of work. A straightforward vapor barrier installation on a smaller crawl space might be done in a day. Larger spaces or projects that include mold remediation, drainage work, or significant repairs take longer.
We’re not rushing through your crawl space. Proper installation means every seam is sealed, every vent is closed correctly, and the dehumidifier is installed and calibrated right. Cutting corners to finish faster just means the system won’t perform the way it should.
You’ll have access to your home the entire time, and we keep the work area contained. Once we’re finished, your crawl space is sealed, clean, and protected. You’re not dealing with ongoing appointments or dragged-out timelines. We schedule the work, complete it properly, and you’re done.
