After inspecting the homeowner’s sump pump system, we found that while the existing setup provided basic drainage, it lacked key components for optimal performance and long-term protection. To improve the system, we installed a new sump pump basin along with a check valve to prevent backflow and ensure efficient water discharge. We then upgraded the crawlspace with our R-5 Insulated Encapsulation System, featuring a heavy-duty 23-mil floor liner to create a sealed, moisture-resistant barrier. To manage humidity and prevent mold growth, we installed two Sierra Watchdog NXT 85 Pint Dehumidifiers for enhanced coverage and airflow. Additionally, we replaced damaged HVAC return ductwork and register runs to improve air circulation and system efficiency throughout the home. This comprehensive solution not only ensured the sump pump was working effectively, but also transformed the crawlspace into a dry, clean, and energy-efficient space.

To fully resolve the homeowner’s crawl space water issue, we implemented a comprehensive moisture management and restoration plan. First, we removed all compromised insulation and treated the entire area with Pro Cleaner Hydrogen Peroxide to sanitize surfaces and eliminate mold or organic growth. We then installed a full-perimeter drainage pipe system directing water into a sump pump basin, which was connected to a discharge line for efficient water removal. To prevent future moisture problems, we encapsulated the crawl space using an R-5 Insulated Encapsulation System with a durable 23-mil floor liner, significantly improving insulation and moisture control. A Sierra Watchdog NXT 85-pint dehumidifier was added to regulate humidity levels and maintain dry conditions year-round. To seal and protect the space, we custom-built a PVC crawlspace door. Additionally, we upgraded the HVAC system by replacing the supply and return ductwork, register runs, and register boots, ensuring better air circulation and energy efficiency throughout the home. This all-inclusive approach created a clean, dry, and healthy crawl space environment, offering the homeowner long-term protection and peace of mind.

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.

After completing a detailed inspection of the crawlspace, we identified several issues including old, ineffective insulation, high humidity levels, and signs of moisture intrusion. To begin the restoration, we removed all deteriorated insulation and performed a Pro Cleaner Hydrogen Peroxide Treatment to sanitize the space and eliminate any mold or microbial growth. We then installed a full perimeter drainage pipe system leading to a custom sump pump pit, equipped with a 1/3 HP sump pump and a discharge line to efficiently manage water removal. To control humidity, we blocked the crawlspace vents and installed a heavy-duty 15-mil vapor barrier across the floor and walls, creating a sealed environment. A Sierra Watchdog NXT 85 Pint Dehumidifier was added to maintain optimal humidity levels year-round. Finally, we custom-built a durable PVC crawlspace door to secure the area while preserving the encapsulation integrity. This comprehensive solution transformed the crawlspace into a clean, dry, and well-protected part of the home.

To address the homeowner’s concerns and prevent any future issues caused by the loose dryer vent, we implemented a full crawlspace moisture control solution. We began by removing the compromised insulation, which had been affected by excess humidity. To manage water intrusion, we installed a full perimeter drainage pipe system leading to a sump pump basin, where we placed a reliable 1/3 HP sump pump to actively remove collected water. A discharge line was connected to ensure proper water flow away from the home. We then blocked unnecessary vents and installed a heavy-duty 15 mil vapor barrier to seal the crawlspace against ground moisture. For ongoing humidity control, we added a Sierra Watchdog NXT 85 Pint Dehumidifier. To complete the system, we custom-built a new, durable PVC crawlspace door for added protection and access. These upgrades gave the homeowner peace of mind, knowing their crawlspace was properly sealed, ventilated, and protected from future moisture-related issues.

To meet the homeowner’s needs, we first installed a full perimeter drainage pipe system to effectively manage water around the crawlspace. We then set up a sump pump basin equipped with a reliable 1/3 HP sump pump and connected a discharge line to ensure efficient removal of any collected water. Next, we applied the Crawlspace Doctor Exclusive Encapsulation System to seal the entire crawlspace, providing a durable moisture barrier and protecting the space from dampness and mold. To maintain optimal humidity levels, we installed a high-capacity Sierra Watchdog NXT 120 dehumidifier. Finally, to maximize the crawlspace’s usability for storage, we built a sturdy wooden platform, giving the homeowner easy and organized access to this newly transformed space.

To address the homeowner’s concerns and fully resolve the issue, we implemented a comprehensive remediation and prevention plan. We began by using soda blasting to safely and effectively remove any mold present on the affected surfaces. To prevent future water intrusion, we installed a new drainage pipe and a sump pump system, including a 1/3 HP sump pump, a sump pump basin, and a discharge line to redirect water away from the home. Additionally, we installed a full encapsulation system to seal and protect the crawl space, along with a high-performance dehumidifier to control moisture levels. To ensure clean and efficient airflow, we replaced the existing ductwork and upgraded the HVAC system. Together, these solutions not only addressed the current mold issue but also provided long-term protection against future moisture-related problems.

To address the homeowner’s concerns, our team implemented a comprehensive solution to restore the structural integrity and improve the overall condition of the home. We began by treating the affected areas with our Pro Cleaner Hydrogen Peroxide Treatment to eliminate mold and sanitize the rotting wood. To control moisture levels and prevent future issues, we blocked unnecessary vents and installed a durable 9 mil vapor barrier throughout the crawlspace. We also installed a Sierra Watchdog NXT 85 Pint Dehumidifier to maintain consistent humidity control. For added protection and security, we custom-built a new PVC crawlspace door. Structurally, we reinforced the flooring by doubling or scabbing the compromised floor joists, installing a steel beam for increased load-bearing support, and adding PowerPost Floor Supports to correct the sloping floors and provide long-term stability. This thorough approach ensured a safer, more stable home environment for the homeowner.
