Your floors feel warmer in winter. The air smells clean, not musty. Your energy bills drop because your HVAC isn’t fighting humidity all summer long.
That’s what proper crawl space encapsulation does. It seals out moisture before it can rot floor joists, feed mold growth, or invite pests into the one part of your home you’d rather not think about.
In Jamestown’s humid climate, crawl spaces become problem zones fast. When relative humidity climbs above 60%—which happens often here—wood starts to soften, mold spores multiply, and insects move in. A vapor barrier installation stops that cycle by creating a sealed environment that keeps ground moisture where it belongs: in the ground.
You’re not just protecting your crawl space. You’re protecting the air your family breathes, the structural integrity of your home, and the value you’ve built in one of Jamestown’s most desirable neighborhoods.
We’ve been serving Jamestown and the greater Greensboro area with crawl space solutions that actually last. We’re BBB Accredited, and our work is backed by warranties that prove we stand behind what we install.
Rick Watson leads our team, and we know North Carolina’s climate creates specific challenges. High humidity, temperature swings, and seasonal rainfall mean your crawl space needs more than a basic fix. It needs a system designed for the conditions you’re dealing with here.
We’ve seen what happens when homeowners wait too long—$15,000 foundation repairs, air quality problems that trigger allergies, and pest infestations that could’ve been avoided. Our job is to catch those problems early or prevent them entirely with dehumidifier installation, vapor barriers, and moisture control systems that work in Jamestown’s real-world conditions.
First, we inspect your crawl space to see what we’re working with. That means checking for standing water, measuring humidity levels, looking at your floor joists for rot or damage, and identifying where moisture is getting in.
Next, we handle any existing problems. If there’s mold, we remove it. If there’s debris or old insulation that’s holding moisture, we clear it out. You can’t seal a crawl space that’s already compromised—you have to start clean.
Then we install a heavy-duty vapor barrier across the floor and up the walls. This isn’t the thin plastic you’d find at a hardware store. It’s a thick, durable liner that blocks ground moisture from evaporating into your crawl space. We seal every seam and anchor it properly so it doesn’t shift or tear.
Finally, we install a crawl space dehumidifier if your space needs it. Even with a vapor barrier, some homes in Jamestown benefit from active humidity control, especially during summer months when outdoor air is saturated. The dehumidifier keeps levels below 60% year-round, which is the threshold where mold and rot start to take hold.
Ready to get started?
You get a sealed system that controls moisture, not just covers it up. That includes vapor barrier installation across every square foot of your crawl space floor and foundation walls, sealed vents to stop humid outdoor air from getting in, and a dehumidifier installation if your space needs active moisture management.
In Jamestown, where the median home was built in 1989, many crawl spaces were designed with vented systems that actually make humidity worse. Modern encapsulation flips that approach. We seal the space, control the environment, and give you a dry, stable area underneath your home.
The result is measurable. Homeowners typically see energy savings of 15-20% because their HVAC systems aren’t working overtime to cool humid air. You’ll notice fewer allergens in your indoor air since up to half of what you breathe on your first floor comes from the crawl space below. And you’ll avoid the $5,000 to $25,000 foundation repairs that moisture damage causes when it’s left unchecked.
Crawl space insulation is often part of the conversation, too. If your floors are cold in winter, adding insulation to your encapsulated crawl space makes a noticeable difference. But insulation only works when moisture is controlled first—otherwise, you’re just insulating a damp space, which creates more problems than it solves.
Most crawl space encapsulation projects in Jamestown run between $5,000 and $8,250, depending on the size of your crawl space and what condition it’s in when we start. If there’s existing mold, standing water, or structural damage, those issues get handled first, which can add to the total.
A typical 1,500-square-foot crawl space with standard moisture issues falls right in that range. Larger homes or spaces that need extensive mold removal, drainage work, or floor joist repairs will cost more.
The investment pays back. You’ll see lower energy bills within the first year, and you’re avoiding much bigger expenses down the road—foundation repairs average $10,000 to $25,000 in this area when moisture problems go untreated. Encapsulation also increases your home’s value, which matters in Jamestown’s strong real estate market where buyers and inspectors specifically look for moisture issues during home sales.
Most encapsulation jobs take one to three days, depending on the size of your crawl space and what prep work is needed. A straightforward vapor barrier installation in a clean, dry crawl space might be done in a day. A space that needs mold removal, debris clearing, or drainage improvements will take longer.
We’ll give you a clear timeline after the inspection. You’ll know exactly what we’re doing, how long each phase takes, and when you can expect the work to be finished.
The process isn’t disruptive. We’re working underneath your home, so you won’t have contractors moving through your living areas all day. Most homeowners go about their normal routines while we’re on-site. Once we’re done, your crawl space is sealed, your humidity is controlled, and you’re protected from the moisture problems that plague homes in North Carolina’s climate.
Yes, and here’s why. Humid air takes more energy to cool than dry air. When your crawl space is open to ground moisture and outside humidity, that damp air rises into your home. Your HVAC system has to work harder and run longer to reach the temperature you set on your thermostat.
Encapsulation stops that. By sealing out moisture with a vapor barrier and controlling humidity with a dehumidifier, you create a stable environment that doesn’t flood your home with damp air. Most homeowners see energy savings of 15-20% after encapsulation.
In Jamestown, where summer humidity regularly pushes into the 70-80% range, that difference is real. You’ll notice your air conditioner cycling less often, and your home will feel more comfortable even when the thermostat is set a few degrees higher. Over time, those savings add up—enough to offset a significant portion of your encapsulation investment within just a few years.
It depends on your specific crawl space and Jamestown’s climate conditions. A vapor barrier blocks moisture from the ground, but it doesn’t control humidity that comes from other sources—like humid outdoor air that leaked in before encapsulation or moisture that’s already in the wood and soil.
A crawl space dehumidifier actively pulls moisture out of the air and keeps humidity levels below 60%, which is the point where mold starts growing and wood begins to rot. In North Carolina’s humid climate, most encapsulated crawl spaces benefit from a dehumidifier, especially during summer months.
We’ll measure your crawl space humidity during the inspection and recommend a dehumidifier if your levels are high or if your home’s layout makes it prone to moisture issues. Some crawl spaces stay dry with just a vapor barrier. Others need that extra layer of control. We’ll tell you which situation you’re in and why, so you can make an informed decision based on your home’s actual conditions—not a one-size-fits-all sales pitch.
We remove it before we encapsulate. Sealing mold inside your crawl space doesn’t solve the problem—it just hides it. Mold needs to be cleaned off surfaces, treated, and removed so you’re starting with a clean space.
Crawl space mold removal involves scrubbing affected wood and surfaces, applying antimicrobial treatments, and removing any materials that are too damaged to save. If your insulation is moldy or your vapor barrier (if you have one) is covered in growth, we pull it out and dispose of it properly.
Once the mold is gone and the space is dry, we install your new vapor barrier and dehumidifier system. That prevents mold from coming back because you’ve eliminated the moisture that feeds it. Most mold problems in Jamestown crawl spaces are caused by humidity above 60%—fix the humidity, and mold can’t grow. It’s that straightforward.
You’ll usually notice signs upstairs before you ever look in your crawl space. Musty smells, especially near floors or in certain rooms, are a giveaway. Cold or uneven floors in winter mean your crawl space isn’t insulated or sealed properly. Higher-than-normal energy bills, especially in summer, suggest your HVAC is fighting humidity from below.
If you do look in your crawl space, standing water, damp soil, condensation on pipes or ducts, and visible mold on floor joists are all clear indicators. Sagging or soft floor joists mean moisture has been there long enough to cause wood rot.
In Jamestown, moisture problems are common because of our climate. High humidity, seasonal rain, and temperature swings create perfect conditions for crawl space issues. If you’re seeing any of these signs, it’s worth getting an inspection. We’ll measure your humidity levels, check for structural damage, and tell you exactly what’s going on—and what it’ll take to fix it for good.
