Atlanta Crawl Space Encapsulation

Address crawl space moisture effectively with AquaGuard's professional crawl space encapsulation services.

Most crawl spaces are unwelcoming and characterized by their dark, damp, and musty environments. However, not only can a neglected crawl space mean lost opportunity for storage space, it can also serve as a catalyst for health problems and structural damage. Crawl space moisture problems often lead to more serious issues like mold, pest infestations, rotting floor joists, high energy bills, and more.

At AquaGuard Foundation Solutions, it’s our goal to help Atlanta and North Georgia homeowners transform their nasty crawl space into a clean, dry, healthy, usable, and energy efficient space with our patented crawl space encapsulation system.

We offer free, no-obligation crawl space inspections, after which we’ll tell you exactly what’s causing your issue and exactly how much it’ll cost to repair.

What is Crawl Space Encapsulation?

Crawl space encapsulation refers to the process of waterproofing, insulating, sealing, and conditioning the crawl space to eliminate moisture and high humidity issues. The combination of installing an effective drainage system, insulating the crawl space, sealing floors and walls, and adequately dehumidifying the air not only prevents groundwater or wall moisture from entering the crawl space, but it also regulates crawl space humidity and temperature, often making it the most regulated and climate-controlled area in your home!

What’s the Difference Between Sealing Your Crawl Space and Encapsulating It?

Sealing your crawl space and encapsulating it are often confused, but they’re not the same.
Crawl space sealing focuses on blocking outside air and moisture by covering the ground and closing vents.
Crawl space encapsulation, on the other hand, is a full waterproofing and moisture-control system. It includes drainage, a vapor barrier, insulation, and dehumidification to fully isolate the crawl space from the earth and outdoor air.

Think of sealing as addressing the surface, while encapsulation protects the entire environment.
We’ll walk through the full process later in this guide.

What Are the Benefits of an Encapsulated Crawl Space?

Our Atlanta crawl space vapor barriers and encapsulation services come with a wide range of benefits. In addition to properly draining existing moisture and sealing walls and floors to prevent water from leaking into the crawl space, encapsulating your crawl space also provides the following advantages:

Improved Air Quality – Encapsulation helps keep the air in your home cleaner and healthier. When crawl space humidity is high, that damp, musty air gets pulled into the living space, carrying mold spores, odors, and allergens with it. By sealing the crawl space and controlling moisture, you prevent contaminated air from circulating through your home—resulting in fresher, cleaner air for your family.
Added Storage Space – Encapsulation turns a damp, dirty crawl space into a clean, dry, usable area. Homeowners gain safe storage without worrying about water damage, mold, or high humidity ruining belongings.
Greater Energy Efficiency – A sealed, dehumidified crawl space helps your HVAC system work more efficiently. When humidity is controlled, the air is easier to cool, lowering energy bills. Sealing off gaps, vents, and moisture pathways also reduces temperature swings, helping your home stay comfortable year-round.
Pest Prevention – Pests thrive in damp, dark, humid spaces. Encapsulation removes the moisture and organic conditions they rely on, making your crawl space far less inviting to termites, rodents, cockroaches, and other nuisance pests.

Mold Prevention – Mold grows quickly when humidity reaches 60% or higher. Encapsulation keeps humidity below that threshold, dries out the space, and removes the conditions mold needs to survive. This protects your home from musty odors, allergy flare-ups, and costly mold remediation.
Structural Protection – Moisture, pests, and mold can weaken wooden support beams and floor joists, leading to sagging floors, sticking doors, cracks, and long-term structural issues. Encapsulation protects these materials by keeping the crawl space dry and stable, helping extend the life of your home’s foundation and framing.

How to Encapsulate a Crawl Space

Crawl space encapsulation services from AquaGuard are the best way to protect your home’s overall health and safety from the ground up. Encapsulating crawl spaces typically goes like this:

1. Prepare the Crawl Space

We begin by thoroughly inspecting the crawl space to identify any existing issues such as water leaks, mold, or pests. It’s important to address these problems first by cleaning the crawl space, sealing any cracks or gaps in the foundation walls and ensuring proper drainage around the exterior of the home.

2. Install Vapor Barrier

Then, we lay our heavy-duty CrawlSeal™ vapor barrier on the ground throughout the crawl space, making sure each seam overlaps to ensure an airtight seal throughout. We extend the barrier a few inches up the walls, fastening it with adhesive or mechanical fasteners to create a continuous moisture barrier that locks out water and wet air.

3. Insulate the Walls

Next, we attach rigid foam board insulation to the crawl space walls, ensuring it fits snugly against the vapor barrier. We seal all seams and edges with foam board tape or spray foam to prevent air leaks and improve energy efficiency.

3. Seal and Condition the Space

Lastly, we seal vents and other openings to prevent humid air from entering. We’ll install a dehumidifier or connect the crawl space to the home’s HVAC system to maintain a controlled environment. Regularly monitoring humidity levels and inspecting the encapsulation helps ensure it remains intact and effective.
