Shreveport's humid subtropical summers drive constant moisture into crawl spaces of pier-and-beam homes built before 1970 in Highland and Broadmoor. These tight, low-ventilation areas trap condensation against floor joists and subfloors, allowing black mold to colonize cellulose insulation and sill plates. Remediation requires full plastic sheeting containment, HEPA vacuuming of settled spores, and antimicrobial treatment of exposed wood before any new insulation goes in.
Caddo Parish soil stays saturated after heavy spring rains, pushing water under foundations in South Highlands and Cedar Grove. We install vapor barriers and French drains tied to existing grading rather than relying on interior sump pumps alone. Edge cases include homes near the Shreveport Riverfront where high water tables make full encapsulation necessary to stop recurring growth on HVAC ducts that run through the crawl.
Many Queensborough and Allendale properties have partial basements added later, creating cold joints that leak during mild winters. We remove affected drywall up to 18 inches above the water line, treat the concrete with penetrating sealers, and restore with mold-resistant board. Work follows Louisiana residential code requirements for ventilation and access doors so inspectors sign off without extra visits.
Technician insight
In Shreveport, the thing that catches most people out with Basement and Crawl Space Mold Remediation is the combination of high summer humidity and older pier-and-beam homes in neighborhoods like Broadmoor and Highland where crawl spaces sit only 18 inches off the ground with almost no cross-ventilation.
Broadmoor Crawl Space After Spring Rains
Heavy rains left standing water under a 1960s home in Broadmoor. We found black mold on joists and insulation near the HVAC return. After containment and removal we installed a sealed vapor barrier and small dehumidifier. The homeowner reported stable humidity readings through the next summer.

How it works
- 1
Site Assessment
Inspect all accessible wood and soil surfaces in the crawl or basement, checking for active moisture sources tied to local drainage.
- 2
Containment Setup
Seal the work area with plastic sheeting and negative air to prevent spores from reaching living spaces above.
- 3
Removal and Treatment
Remove affected materials, HEPA vacuum surfaces, and apply EPA-registered antimicrobials to wood and concrete.
- 4
Moisture Control Installation
Place vapor barriers or dehumidification as needed for the humid climate and soil conditions in the neighborhood.
- 5
Final Clearance
Verify dryness and clearance with moisture meters before restoring access and ventilation.
Pricing
Pricing varies by access difficulty and square footage in older Shreveport homes; most jobs fall between inspection and full encapsulation.
