You stop smelling that musty odor every time you walk through your hallway. Your energy bills drop because your HVAC isn’t fighting against humid air seeping up through the floors. The air in your home feels cleaner, and you’re not dealing with unexplained allergy symptoms anymore.
That’s what proper crawl space encapsulation does. It creates a controlled environment under your home that keeps moisture out, protects your floor joists from rot, and stops mold before it becomes a health hazard or a $15,000 remediation project.
North Carolina’s humidity makes crawl spaces a breeding ground for problems. When outdoor air hits your cooler crawl space, condensation forms. Add in groundwater seepage and exposed dirt floors, and you’ve got the perfect recipe for mold, pests, and structural damage. Encapsulation stops this cycle by sealing everything off with a vapor barrier, controlling humidity with a dehumidifier, and giving you a dry, protected foundation that lasts 20+ years.
We’ve spent over 14 years solving crawl space problems for homeowners throughout the Greensboro area, including Elon. Rick Watson and his team know exactly what North Carolina’s climate does to crawl spaces because we’ve seen it hundreds of times.
We’re BBB Accredited with an A+ rating, and we focus on two things: crawl space health and indoor air quality. That combination matters because up to 50% of the air you breathe in your home comes from your crawl space through the stack effect. When we encapsulate your crawl space, we’re not just protecting your foundation—we’re improving the air your family breathes every day.
Elon’s location in the Piedmont means you’re dealing with clay soils that hold water and humidity levels that regularly exceed 70% in summer. We account for these local conditions in every installation, which is why our encapsulation systems actually work long-term instead of just covering up the problem temporarily.
First, we inspect your crawl space to identify moisture sources, existing damage, and any mold or pest issues. You get a clear assessment of what’s happening and what needs to happen to fix it.
Next, we handle crawl space cleaning if needed—removing debris, old insulation, and anything that shouldn’t be there. If there’s mold, we address it properly before moving forward. Then comes vapor barrier installation, where we seal your crawl space floor and walls with a heavy-duty liner that stops ground moisture from entering your home.
We install proper drainage if water intrusion is an issue, ensuring groundwater has somewhere to go besides your crawl space. Crawl space insulation goes in where it’s needed to create a thermal barrier. Finally, we add a dehumidifier installation to actively control humidity levels year-round, keeping them in that ideal 40-50% range that prevents mold growth and protects your home’s structure.
The whole process typically takes a few days depending on your crawl space size and condition. When we’re done, you have a sealed, dry, controlled environment that protects your home investment for decades.

Our crawl space encapsulation service covers everything needed to create a permanently dry, healthy space under your Elon home. You get a professional-grade vapor barrier that seals out moisture from the ground and walls. We’re talking about durable materials designed to last 20-25 years, not the thin plastic some companies use that tears and fails within a few years.
Moisture control is the foundation of the system. Elon’s humid climate means your crawl space needs active dehumidification, not just passive barriers. We install commercial-grade dehumidifiers sized specifically for your space, designed to handle North Carolina’s summer humidity that regularly pushes past 70%. This keeps your crawl space humidity between 40-50%, which is the sweet spot where mold can’t grow and wood stays protected.
If your crawl space has standing water, drainage issues, or signs of ongoing water intrusion, we address those problems as part of the encapsulation. That might mean installing drainage systems, sealing foundation cracks, or regrading problem areas. We also handle crawl space insulation where it makes sense for energy efficiency, which can cut your heating and cooling costs by 15-20% according to Department of Energy research.
The result is a complete system that works together to keep your crawl space dry, your home more comfortable, and your foundation protected from the moisture damage that costs Elon homeowners thousands in repairs every year.
Most complete crawl space encapsulation projects in the Elon area run between $13,000 and $20,000 depending on your crawl space size, current condition, and what problems need fixing. That typically includes vapor barrier installation, dehumidifier, drainage work if needed, and any necessary mold remediation or crawl space cleaning.
Smaller crawl spaces with minimal issues might come in around $10,000-$12,000. Larger homes or crawl spaces with significant water intrusion, structural concerns, or extensive mold problems can push higher. The investment makes sense when you consider that crawl space moisture damage—rotted floor joists, mold remediation, pest damage—can easily cost you $15,000 to $30,000 to repair if you let it go.
You’re also looking at real energy savings. Studies show properly encapsulated crawl spaces reduce heating and cooling costs by 15-20%, which means you’re saving $200-$400+ per year on energy bills. Over the 20+ year lifespan of a quality encapsulation system, that adds up to thousands in savings while protecting your home’s structural integrity and your family’s health.
A professionally installed crawl space encapsulation system lasts 20-25 years or more when properly maintained. The vapor barrier itself—if it’s quality material installed correctly—can last the lifetime of your home. The dehumidifier will need occasional filter changes and might need replacement after 10-15 years depending on how hard it works.
The key is proper installation. Cheap vapor barriers that aren’t sealed correctly or dehumidifiers that aren’t sized right for your space will fail much sooner. That’s why the contractor you choose matters more than finding the lowest price. A system that fails in 5 years because corners were cut isn’t saving you money.
Maintenance is minimal but important. You’ll want to check your dehumidifier periodically, make sure the vapor barrier hasn’t been disturbed, and keep an eye out for any new moisture sources. Most homeowners spend maybe an hour a year on crawl space maintenance once it’s encapsulated. Compare that to constantly running dehumidifiers, dealing with musty smells, or worrying about mold growth, and it’s a pretty easy trade-off.
Yes, if that musty smell is coming from your crawl space—which it usually is. That odor is mold and mildew growing in the damp environment under your home. Because of the stack effect, up to 50% of the air in your home comes from your crawl space, carrying that smell and mold spores with it.
Crawl space encapsulation eliminates the moisture that mold needs to grow. Once we seal your crawl space with a vapor barrier and control humidity with a dehumidifier, the environment becomes inhospitable to mold. No moisture means no mold growth, which means no musty smell. Most homeowners notice the difference within a few weeks as the existing mold dies off and stops producing that odor.
If you’re dealing with significant existing mold, we’ll address that as part of the encapsulation process through proper crawl space cleaning and mold remediation. The goal isn’t just to cover up the smell—it’s to eliminate the source permanently so you’re breathing cleaner air and not exposing your family to mold spores that can trigger allergies and respiratory issues.
In Elon, yes. A vapor barrier alone isn’t enough to control crawl space humidity in North Carolina’s climate. The barrier stops moisture from the ground, but you still have humid outdoor air entering through vents and gaps, plus any residual moisture already in your crawl space.
Summer humidity in this area regularly exceeds 70%. When that humid air enters your crawl space and hits cooler surfaces, it condenses into water. That’s how you end up with moisture problems even with a vapor barrier installed. A properly sized dehumidifier actively removes moisture from the air, keeping humidity levels in that 40-50% range where mold can’t grow and wood stays dry.
Think of it this way: the vapor barrier is your first line of defense against ground moisture, and the dehumidifier is your active control system that handles everything else. Together, they create an environment where moisture simply can’t accumulate. Without the dehumidifier, you’re only solving half the problem, and you’ll likely end up with condensation issues, especially during our humid summers.
Encapsulation creates a thermal and moisture barrier between your home and the outside environment, which means your HVAC system doesn’t have to work as hard. In summer, you’re not fighting hot, humid air seeping up through your floors. In winter, you’re not losing heat to a cold, damp crawl space. That reduced workload translates directly to lower energy consumption.
The Department of Energy confirms that proper crawl space encapsulation can reduce heating and cooling costs by an average of 15%, with some studies showing savings up to 20%. For most Elon homeowners, that’s $200-$400 per year in energy savings. Over the 20+ year life of your encapsulation system, you’re looking at $4,000-$8,000 in savings.
The energy efficiency comes from multiple factors: sealed air leaks that were letting conditioned air escape, insulation that maintains temperature, and controlled humidity that makes your home feel more comfortable at the same thermostat setting. When your HVAC isn’t constantly cycling to compensate for temperature swings and humidity from your crawl space, it runs less often, lasts longer, and costs less to operate.
Crawl space moisture creates a chain reaction of problems that get expensive fast. Mold grows when humidity exceeds 60%, releasing spores into your home’s air that cause allergic reactions, respiratory issues, and headaches. Your floor joists and subfloor start rotting when they’re constantly exposed to moisture, which compromises your home’s structural integrity and can cost $10,000-$30,000 to repair.
Pests love damp crawl spaces. Termites are attracted to moisture and feed on your wooden structures. Cockroaches, spiders, and rodents seek out humid areas to nest. You’re basically creating a perfect habitat for everything you don’t want living under your home. High humidity also makes your home harder to heat and cool, forcing your HVAC system to work overtime and driving up your energy bills by 15-25%.
The insidious part is how slowly these problems develop. You might notice a musty smell first, then some allergy symptoms, then sagging floors years later when the structural damage becomes obvious. By that point, you’re looking at major repairs instead of preventive encapsulation. That’s why addressing crawl space moisture early—before you have visible mold or structural issues—saves you money and protects your home’s value long-term.
