Your floors stay warm in winter. Your AC doesn’t run constantly in summer. You stop worrying about that musty smell creeping into your living room.
When humidity stays below 60% year-round, mold can’t grow. Wood doesn’t rot. Pests lose interest because the environment they need to thrive simply doesn’t exist anymore.
You’re not just fixing a crawl space. You’re protecting the air your family breathes, the structure holding up your home, and the investment you’ve made in Kernersville. Most homeowners see energy savings within the first billing cycle, and the structural protection pays dividends for decades.
The difference between an encapsulated crawl space and an untreated one isn’t subtle. It’s the difference between a home that fights you and one that works with you.
We’ve spent over 30 years improving indoor air quality for homes across the Greensboro area, including right here in Kernersville. We’ve seen what North Carolina’s humid summers and unpredictable springs do to untreated crawl spaces.
Kernersville sits in a high-risk flooding zone where groundwater vaporizes the moment temperatures rise. That’s not a minor inconvenience—it’s a structural threat. We understand the local climate because we’ve been working in it since before most national franchises existed.
You’re not getting a sales pitch from someone reading off a script. You’re getting a team that knows exactly what happens when humidity hits 70% in July, and how to prevent it before your floor joists start sagging.
We start with a full crawl space inspection to identify moisture sources, existing damage, and humidity levels. You get a clear assessment of what’s happening under your home and what needs to happen next.
Next comes crawl space cleaning—removing debris, old insulation, and any contaminated materials. If there’s mold, we address it. If there’s standing water, we figure out why and fix the source.
Then we install a reinforced vapor barrier across the entire crawl space floor and up the foundation walls. This isn’t the thin plastic you see at hardware stores—it’s a 20-mil polyethylene barrier designed to last decades. We seal every seam, every pier, every penetration.
After the vapor barrier installation, we add crawl space insulation to your walls or rim joists, depending on your home’s needs. Finally, we install a commercial-grade dehumidifier calibrated to maintain humidity between 45-50%. You’re not guessing if it’s working—you can monitor it.
The whole process typically takes two to three days, depending on your crawl space size and condition. You get a space that’s cleaner than most basements and dry enough to store belongings without worry.

Full crawl space encapsulation includes vapor barrier coverage across 100% of your crawl space floor and foundation walls, sealed at every seam and penetration point. You’re getting complete moisture protection, not partial coverage that leaves gaps for humidity to sneak through.
Dehumidifier installation is part of the system—not an upsell. We size the unit based on your crawl space square footage and Kernersville’s climate conditions. North Carolina’s outdoor humidity ranges from 45-61%, which means your crawl space needs active moisture control, not just a plastic sheet.
If your crawl space has existing mold, damaged insulation, or standing water issues, we handle that before encapsulation begins. Sealing moisture inside doesn’t solve the problem—it makes it worse. We also address foundation vents, sealing them to prevent outside humid air from entering your controlled environment.
The goal isn’t to meet a checklist. It’s to create a crawl space that maintains 40-50% humidity year-round, protects your floor joists from rot, and stops feeding mold spores into your HVAC system. That’s what proper encapsulation does when it’s done right.
Most crawl space encapsulation projects in Kernersville range from $3,500 to $8,000, depending on your crawl space size, current condition, and what needs to be addressed before we can encapsulate. If you’ve got significant mold remediation, structural repairs, or drainage issues, costs go up.
A 1,200 square foot crawl space in good condition typically runs around $5,000 to $6,000 for full encapsulation with vapor barrier, insulation, and dehumidifier installation. Larger homes or crawl spaces with accessibility challenges cost more because they require more materials and labor.
You’ll see quotes all over the map if you’re shopping around. Some companies lowball the estimate and upsell you later. Others quote you for systems you don’t actually need. We give you a flat quote after inspecting your crawl space—no surprises, no pressure to add services that don’t make sense for your situation.
Yes, but the savings depend on your current crawl space condition and how hard your HVAC system is working to compensate. Most homeowners see 15-20% reductions in heating and cooling costs after encapsulation, especially during Kernersville’s humid summer months.
Here’s why it works: untreated crawl spaces let humid air infiltrate your home, making your AC run longer to remove that moisture. In winter, cold air seeps up through your floors, forcing your heater to work overtime. Encapsulation stops both problems by creating a controlled environment that doesn’t fight your HVAC system.
The energy savings aren’t immediate—you’ll notice the difference over a full billing cycle. But the comfort change is instant. Your floors feel warmer in January, your air feels less muggy in July, and your system isn’t cycling on and off constantly trying to manage humidity it can’t control.
A properly installed crawl space encapsulation system lasts 15 to 20 years, and in many cases, it lasts the lifetime of your home. The vapor barrier itself is built to withstand decades of ground contact without tearing or degrading.
The dehumidifier is the only component that may need replacement, typically after 10 to 15 years of continuous operation. That’s normal wear for any mechanical equipment. The vapor barrier, insulation, and sealed vents don’t require replacement unless you have a plumbing leak or other water intrusion that compromises the system.
You’re not looking at ongoing maintenance costs or frequent repairs. Once it’s installed, the system works passively. Check your dehumidifier once or twice a year to empty the reservoir if it’s not plumbed to drain, and you’re done. This isn’t a temporary fix—it’s a permanent solution to crawl space moisture problems.
Your crawl space should stay between 40-50% relative humidity year-round. That’s the range where mold can’t grow, wood doesn’t rot, and pests won’t nest. Anything above 60% creates conditions for mold growth within 24 to 48 hours.
Kernersville’s outdoor humidity regularly hits 60% or higher during summer months, which means an untreated crawl space will mirror those conditions—or exceed them. Encapsulation with a properly sized dehumidifier keeps your crawl space in the safe zone regardless of what’s happening outside.
You can monitor this yourself if your dehumidifier has a built-in hygrometer, or you can use a standalone humidity monitor. The number matters because it’s the difference between a crawl space that’s protecting your home and one that’s actively damaging it. We calibrate your dehumidifier to hit that 45-50% target and maintain it automatically.
Yes. Once your crawl space is encapsulated and maintaining proper humidity levels, it becomes a clean, dry storage area. You’re not dealing with dirt floors, moisture, or the risk of mold growing on your belongings.
That said, you still want to keep stored items off the vapor barrier to avoid punctures. Use plastic shelving or pallets to create airflow underneath boxes and containers. Avoid storing anything that attracts pests or retains moisture, like cardboard boxes filled with fabric.
The transformation is significant. Most homeowners are surprised at how clean and usable the space becomes after encapsulation. You go from a dirt-floor crawl space you’d never enter without gloves and a mask to a space that looks and feels like a conditioned part of your home. It’s not a basement, but it’s functional storage space you can actually use.
If you live in Kernersville, you have moisture in your crawl space—you just might not see it yet. North Carolina’s climate guarantees it. The question isn’t whether you have moisture, it’s whether that moisture has caused visible damage.
Crawl space moisture doesn’t always show up as standing water or dripping pipes. It shows up as higher energy bills, musty odors, cold floors in winter, and eventually, sagging floors or mold growth in your HVAC ducts. By the time you see the problem, you’re often looking at structural repairs that cost significantly more than encapsulation.
Encapsulation is preventive. You’re stopping damage before it starts, not reacting to it after your floor joists are rotted. If you’re buying a home in Kernersville and the inspection report mentions high crawl space humidity, address it now. If you’ve lived here for years and never thought about your crawl space, it’s worth having someone take a look before small problems become expensive ones.
