Mold growth in your home—especially in areas like crawl spaces or interior walls—can be a serious threat to your health and your property. But tackling mold the right way means more than just wiping it down. It takes a two-part professional process: expert mold removal (inside the home) and encapsulation (in the crawl space underneath your home).
At BioSweep Southeast, we tailor each service to fit the location and conditions of the mold problem. We don’t take shortcuts—and we don’t treat every space the same. This guide breaks down our proven approach to mold removal and encapsulation, so you know exactly what to expect and how to protect your home long term.
What Is Expert Mold Removal and Crawl Space Encapsulation?
The term “mold removal and encapsulation” refers to two distinct services:
- Interior Mold Remediation with Containment – Inside your home, we remove active mold, sanitize the air, and set up sealed containment zones to stop spores, dust, and debris from spreading during cleanup.
- Crawl Space Encapsulation – Underneath your home, we clean mold from wooden structures and install vapor barriers and moisture control systems to prevent mold from coming back.
Let’s break down how each process works.
Interior Mold Remediation: Sealed Containment + Air Treatment
When mold is growing inside the living space—such as behind walls, in attics, or near HVAC systems—BioSweep Southeast uses a containment-based remediation process. This ensures mold, dust, and airborne contaminants don’t spread throughout the home during cleanup.
Step 1: Inspection and Diagnosis
We begin with a full moisture and mold assessment, using diagnostic tools like moisture meters and infrared cameras to find hidden sources of moisture and contamination.
Step 2: Containment Setup
Before any removal begins, we build a sealed containment area using plastic sheeting, negative air machines, and HEPA filters. This isolates the affected area and protects the rest of your home.
Step 3: Mold Removal and Surface Disinfection
Contaminated materials (like drywall or insulation) are safely removed. Then, we treat surfaces using BioSweep’s Advanced Photocatalytic Oxidation (APO) system. This vapor-based process floods the air with hydrogen peroxide, ozone, and hydroxyl radicals to destroy airborne mold spores and sanitize the space.
Note: APO treatment is only used inside the home—not in crawl spaces.
Step 4: Post-Remediation Report
Every project ends with a detailed report outlining what was done, what was found, and any recommendations to keep your home mold-free.
Crawl Space Encapsulation: Moisture Prevention from the Ground Up
Crawl spaces are notorious for excess moisture, wood rot, and mold growth. If left untreated, mold in a crawl space can impact your home’s structural integrity and contribute to poor indoor air quality.
At BioSweep Southeast, our crawl space encapsulation service transforms this vulnerable area into a dry, mold-resistant zone.
Step 1: Surface Cleaning and Wood Treatment
We begin by removing visible mold from crawl space wood structures using commercial-grade hydrogen peroxide. This kills surface mold and helps preserve the structural components of your home.
Step 2: Vapor Barrier Installation
Next, we install a continuous vapor barrier that covers the crawl space floor and walls. This heavy-duty plastic sheeting locks out ground moisture, reducing the conditions that allow mold to thrive.
Step 3: Moisture and Humidity Control
Encapsulation is paired with moisture control solutions such as:
- Crawl space dehumidifiers
- Sump pumps or drainage improvements
- Vent sealing or mechanical ventilation upgrades
Our goal is to keep humidity below 50%—a level where mold simply can’t grow.
Why You Need Both: Remediation and Prevention
Even after mold is removed from your home, spores can linger in the air or on surfaces—and they’ll return if moisture isn’t controlled. That’s why remediation and encapsulation often go hand-in-hand.
- Use mold remediation with containment when mold is growing inside your living space.
- Use crawl space encapsulation when the mold source is underneath the home or moisture is seeping in from the ground.
Combining both gives your home the long-term protection it needs to stay dry, clean, and healthy.
When to Call for Expert Mold Removal
You should contact a mold professional if you notice:
- Musty or earthy smells—especially in crawl spaces, basements, or closets
- Visible mold growth on walls, insulation, or wood
- High humidity levels or condensation on windows
- Past flooding or water damage
- Ongoing allergy or respiratory issues

- Moisture Control Focus: We don’t just remove mold—we solve the conditions that allowed it to grow in the first place.
Aftercare Tips to Keep Mold Away
Once your mold problem is fixed, keep it from coming back with a few simple habits:
- Use a digital hygrometer to monitor crawl space humidity. Keep it below 50%.
- Run a dehumidifier in damp-prone areas like basements or utility rooms.
- Address leaks and plumbing issues immediately.
- Keep gutters clean and ensure water drains away from the home.
- Schedule yearly crawl space inspections—especially before rainy seasons.
Stop Mold Before It Spreads
Mold spreads fast—and the longer you wait, the harder it becomes to remove. The most effective way to deal with mold is a combination of expert removal inside the home and targeted encapsulation beneath it.
At BioSweep Southeast, we’re here to help you breathe easier, live healthier, and protect your property.
