To resolve the homeowner’s issues with hydrostatic pressure and standing water in the crawlspace, we began by removing all compromised insulation to prepare the space for treatment and repair. We then applied a hydrogen peroxide solution to sanitize the area and eliminate any microbial growth. To address water intrusion, we installed a drainage pipe system leading to a sump pump basin equipped with a 1/3 HP sump pump and a discharge line to efficiently redirect water away from the foundation. We encapsulated the entire crawlspace with a heavy-duty 23 mil floor liner to create a durable, moisture-resistant barrier. To control humidity and improve air quality, a high-efficiency dehumidifier was installed. We also custom-built a sealed crawlspace door to further prevent outside moisture and air intrusion. Finally, we upgraded the HVAC system in the crawlspace by installing new supply and return lines, as well as replacing all register runs and register boots to ensure optimal airflow and energy efficiency. This comprehensive solution fully addressed the moisture issues and significantly improved the home's structural and environmental health.
