If you’re seeing visible mold or smelling a musty odor under your home, the crawl space may have become a breeding ground for mold spores. Rehab Restoration provides crawl space mold removal and professional mold remediation to help protect your floor joists, subfloor, and indoor air quality—and to stop the moisture issues that keep the mold problem coming back.
Crawl spaces are dark, cool, and full of tight spaces—and in older homes across Upstate SC, that often means damp air gets trapped below the living space. When humidity levels stay high or water intrusion continues, mold growth can spread across wood framing like joists and subfloor materials.
EPA guidance notes indoor relative humidity should be kept below 60% (ideally 30–50%) to discourage mold growth
Mold isn’t just a “crawl space issue.” Spores can move upward and affect your home’s air quality, especially if your crawl space is open to the structure. Exposure can contribute to allergic reactions, irritation, and respiratory issues—and people with asthma or sensitivities may feel it sooner.
If you’re experiencing symptoms that get worse at home, or you’ve got persistent musty odors, it’s worth having the crawl space evaluated.
Homeowners often ask about DIY mold cleanup, but crawl space mold isn’t just a surface issue. Mold can embed into porous materials, and disturbing it can release spores into the air. The EPA does not recommend bleach or biocides as a routine method for mold cleanup.
Health agencies note that mold work requires protective equipment, which highlights the risk of exposure—especially in confined areas. In crawl spaces, mold often affects structural wood like floor joists and is tied to ongoing moisture problems.
Because crawl spaces are enclosed and connected to the living space above, professional mold remediation is typically the safer and more effective option. Proper containment, HEPA filtration, and moisture control are critical to removing the mold and preventing it from coming back.
We begin with a detailed crawl space inspection to identify visible mold, moisture sources, and structural impact. This includes checking for plumbing leaks, drainage issues, and ventilation problems, along with measuring humidity and moisture levels on floor joists, subflooring, and masonry surfaces.
Once the scope is defined, we isolate the work area to prevent mold spores from spreading into the living space. Depending on the severity, this may include plastic sheeting, controlled access zones, and airflow management.
Mold remediation is only effective if the conditions that caused the problem are corrected. After removal, we focus on preventing future mold growth by controlling moisture and humidity in the crawl space.
Crawl space mold removal requires more than surface cleaning—it takes trained professionals who understand moisture control, containment, and safe remediation. Rehab Restoration is an IICRC-associated restoration company with an A+ rating from the Better Business Bureau and 100+ five-star reviews from homeowners across Upstate South Carolina.
Our team follows industry-recognized mold remediation standards, uses professional HEPA filtration, and takes the proper steps to protect your home and indoor air during the process. Just as importantly, we focus on fixing the moisture issues that cause crawl space mold in the first place, helping prevent the problem from returning.
Depending on what we find, your prevention plan may include:
The goal is simple: reduce moisture, stabilize humidity, and stop mold growth at the source.
Mold exposure can trigger allergic reactions and respiratory irritation, especially for people with asthma or sensitivities.
EPA does not recommend bleach/biocides as a routine practice for mold cleanup.
EPA guidance suggests keeping indoor RH below 60% (ideally 30–50%) to discourage mold growth.
It depends on your moisture source, drainage, and how the crawl space interacts with the home. Many crawl spaces need a combined plan: moisture control first, then sealing and humidity management.
Yes. Mold spores from the crawl space can move upward into the home through air leaks, ductwork, and natural air movement. Because crawl spaces sit directly beneath the living space, mold growth below the home can impact indoor air quality and contribute to musty odors, allergic reactions, and respiratory irritation. Addressing crawl space mold helps protect both the structure of the home and the air inside it.
The timeline depends on the size of the crawl space, the extent of mold growth, and whether moisture issues need to be corrected. In many cases, crawl space mold removal can be completed in one to three days. More extensive situations that require containment, material removal, or moisture control measures like vapor barriers or dehumidifiers may take longer. After an inspection, we provide a clear timeline so homeowners know what to expect.
If you’re dealing with a mold problem under your home, don’t guess. We’ll identify the cause (leaks, ground moisture, drainage) and recommend the right fix—mold removal, mold remediation, vapor barrier, encapsulation, and humidity control.
