Job completed for Crawl Space Drainage and Mold Treatment

Completion date: September 5, 2024

Location: Huntsville, AL

Why did the customer contact us?

A homeowner reached out requesting an inspection after noticing possible mold growth, sagging insulation, and other concerns in their crawl space. They were worried about the impact on their home's air quality and energy efficiency, as well as the potential for hidden structural issues. During our inspection, we identified visible mold on several surfaces, insulation that was falling or deteriorating due to prolonged moisture exposure, and additional signs of high humidity and poor ventilation that were contributing to the overall problem. These conditions required prompt attention to restore the space and prevent further damage.

Solutions provided:

To resolve the issues found during the inspection, we first removed all compromised insulation and debris to clear the space for remediation and improvements. We then applied a hydrogen peroxide treatment to eliminate mold growth and sanitize all affected surfaces. To address the underlying moisture problems, we installed a complete drainage system including a drain pipe, sump basin, sump pump, and discharge line to actively manage water intrusion. We sealed all foundation vent openings and porch areas using rigid foam board insulation to prevent outside air and moisture from entering. For thermal efficiency, we installed a 3/8” or 375 Mil Insulated Liner on the foundation walls, providing an R-5 insulation value, and covered the crawl space floor with a 38 Mil 100% Reinforced Liner with taped seams for a durable moisture barrier. A high-efficiency dehumidifier was added to control humidity, and we replaced the HVAC supply/return ductwork and register runs to ensure clean, efficient airflow.
