Shreveport’s humid subtropical climate keeps relative humidity high even through mild winters, so black mold often takes hold in crawl spaces and wall cavities of pre-1970 homes common in Highland, Broadmoor and Queensborough. Older pier-and-beam foundations allow moisture from the red clay soil to wick upward, especially after spring rains, and the limited airflow in these tight spaces lets colonies spread behind baseboards before homeowners notice any odor.
We use negative-air machines with HEPA filtration and antimicrobial agents registered for use in occupied homes to avoid cross-contamination into living areas. In neighborhoods like Cedar Grove and South Highlands, where many houses have original plaster and lath, we cut out only the affected sections rather than whole walls, then seal the remaining cavities with an encapsulant that resists future moisture. This approach limits dust and keeps repair costs down for owners who may later sell to buyers concerned about past water intrusion.
HVAC systems in Springlake and Caddo Heights homes frequently pull spores from crawl spaces into ductwork, so we inspect and clean supply runs when the mold source is below the living space. Caddo Parish building codes require proper ventilation after remediation; we install or upgrade crawl-space vents and dehumidifiers sized for the square footage to keep conditions below the 60 percent threshold that supports regrowth.
Technician insight
In Shreveport the thing that catches most people out with Black Mold Removal is how our mild winters still let moisture sit in the crawl spaces of 1950s–60s homes in Broadmoor and Cedar Grove; the red clay never fully dries, so colonies hide behind baseboards until summer humidity spikes and the smell finally appears.
Cedar Grove Crawl Space Growth
After heavy spring rains a homeowner in Cedar Grove noticed a musty odor in the living room. Inspection showed black mold on floor joists from poor perimeter drainage typical of the neighborhood’s clay soil. We contained the space, removed affected insulation, treated the wood, and added vents plus a small dehumidifier. The odor disappeared and humidity stayed below 55 percent through the following summer.

How it works
- 1
On-Site Assessment
We inspect all affected rooms, crawl spaces, and HVAC runs while noting moisture sources tied to local clay soil and drainage patterns.
- 2
Containment and Air Filtration
Plastic barriers and negative-air machines isolate the work zone so spores do not migrate into clean areas of the home.
- 3
Removal and Cleaning
Physically remove moldy materials, treat remaining surfaces with EPA-registered antimicrobials, and clean ducts when needed.
- 4
Drying and Prevention
Install or recommend dehumidification and ventilation upgrades suited to Shreveport’s humidity to stop recurrence.
Pricing
Cost depends on square footage, access difficulty, and whether HVAC or insulation must be replaced.
