After confirming that water intrusion was keeping the crawlspace wet enough to fuel ongoing mold growth, we addressed the problem in the right order—cleaning, controlling water, then sealing and drying the space for the long haul. We began with soda blasting to safely remove mold from affected surfaces and restore cleaner, healthier conditions. Next, we installed a full-perimeter drainage pipe to capture water around the entire foundation and direct it into a sump pump basin, where a dependable 1/3 HP sump pump could collect and remove it. We then ran a dedicated discharge line to carry water safely away from the home so it couldn’t recycle back into the crawlspace. With water under control, we installed our Crawlspace Doctor exclusive encapsulation system to block ground moisture and outside humidity from re-entering the space. To maintain consistent, mold-resistant conditions year-round, we added a Sierra Watchdog NXT 85-pint dehumidifier and finished with a custom-built PVC crawlspace door for a tighter, more durable seal.

After our evaluation confirmed the open-porch exposure was allowing outside moisture to drive rot and weakening key framing components, we fixed both the cause and the structural damage it created. We started by treating affected areas with a Pro Cleaner hydrogen peroxide application to address microbial growth and help sanitize the crawlspace. To stabilize and reinforce the floor system, we installed PowerPost floor supports, doubled/scabbed compromised floor joists where reinforcement was needed, and added a steel beam to restore strength and proper load support. With the structure secured, we focused on long-term moisture control by blocking the foundation vents and installing a durable 9 mil vapor barrier to cut off ground vapor. We then added a Sierra Watchdog NXT 85-pint dehumidifier to keep humidity in a safe range year-round, and finished with a custom-built PVC crawlspace door to create a tighter, more durable seal—helping prevent future moisture intrusion and protecting the repaired structure.

After inspecting the crawlspace, we addressed the key issues by starting with a Pro Cleaner hydrogen peroxide treatment to clean and treat affected wood surfaces and help eliminate moisture-related contamination. Next, we installed a 1/3 HP sump pump to actively remove collected water and keep the crawlspace from staying wet. Finally, we completed the upgrade with the Crawlspace Doctor Exclusive Encapsulation System, sealing the space to block ground moisture and outside air—creating a cleaner, drier, and more stable crawlspace environment long-term.

To solve the standing water and hydrostatic pressure issues, we installed a full interior perimeter drainage pipe system to intercept water along the foundation wall and within the soil profile before it could spread across the crawlspace. That system was pitched to a newly installed sump pump basin, where a 1/3 HP sump pump collects and removes the water through a dedicated discharge line, carrying it safely away from the home. To prevent lingering moisture and humidity from returning, we blocked the foundation vents and installed a 15 mil vapor barrier to separate the crawlspace from ground moisture and outside air. We then added a Sierra Watchdog NXT 85-pint dehumidifier to maintain dry, stable conditions year-round, and finished with a custom-built PVC crawlspace door to improve access while sealing the entry point and helping keep the crawlspace protected.

To solve the crawlspace issues, we started with soda blasting to remove existing fungal growth and surface contamination from the framing, leaving the wood clean and ready for long-term protection. Next, we installed a full interior perimeter drainage pipe system to capture water along the foundation wall and within the soil profile, then directed that collected water to a newly installed sump pump basin. Inside the basin, we set a 1/3 HP sump pump and connected a dedicated discharge line to move water safely away from the home. To control humidity and prevent future moisture-related problems, we installed a Sierra Watchdog NXT 85-pint dehumidifier to actively dry the crawlspace air. Finally, we improved access and sealing at the entry point with a custom-built PVC crawlspace door, helping reduce outside air and moisture intrusion and supporting a cleaner, more stable crawlspace environment.

To solve the moisture issues and protect the home long-term, we sealed and conditioned the crawlspace using our R-5 Insulated Encapsulation System with a heavy-duty 23 mil floor liner, creating a durable barrier against ground moisture and outside air. We paid close attention to sealing seams, edges, and penetrations to ensure the space was truly closed off and controlled. To keep humidity in a safe range year-round, we installed a Sierra Watchdog NXT 85 Pint Dehumidifier, providing active moisture removal even during the most humid months. We finished by building a custom PVC crawlspace door for a tight, long-lasting entry seal—helping the encapsulation system perform at its best and leaving the crawlspace clean, dry, and protected moving forward.

To solve the mold and moisture problem for good, we combined remediation with full water and humidity control. We started by soda blasting the affected surfaces to remove mold and clean the wood properly, then installed a full-perimeter drainage pipe system to capture groundwater and direct it into a new sump pump basin. From there, we added a dependable 1/3 HP sump pump and ran a dedicated discharge line to move water safely away from the foundation. Once bulk water was controlled, we sealed the crawlspace with our Crawlspace Doctor Exclusive Encapsulation System to block ground moisture and outside air from feeding future mold growth. To keep conditions stable year-round, we installed a Sierra Watchdog NXT 120 dehumidifier, and finished with a custom-built PVC crawlspace door to create a tight, durable entry seal—leaving the crawlspace clean, dry, and protected moving forward.

To stop the water intrusion at the cold joint and keep the crawlspace dry long-term, we installed a targeted water-management and moisture-control system. We began with a partial perimeter drainage pipe installation along the affected area to intercept seepage and redirect it to a new sump pump basin. From there, we installed a dependable 1/3 HP sump pump and ran a dedicated discharge line to carry water safely away from the foundation so it couldn’t cycle back toward the home. Once the bulk water was controlled, we sealed and protected the crawlspace with our Crawlspace Doctor Exclusive Encapsulation System, which blocks ground moisture and outside air from feeding humidity issues. To keep conditions stable year-round, we finished by installing a Sierra Watchdog NXT 85 Pint Dehumidifier, maintaining healthy humidity levels and helping prevent mold, odors, and future moisture-related deterioration.

To address the moderate fungal growth and high humidity, we first removed the existing insulation so we could properly access and clean the affected framing. We then treated the crawl space with our Pro Cleaner hydrogen peroxide solution to clean and sanitize the framing system. To manage water and moisture, we installed a full perimeter drainage pipe system leading to a new sump pump basin with a 1/3 HP sump pump and discharge line to move water away from the home. After that, we installed an R-5 insulated encapsulation system with a heavy-duty 23-mil floor liner to separate the crawl space from the ground and outside air. A Sierra Watchdog NXT 85-pint dehumidifier was added to control humidity levels, and we finished the project with a custom-built PVC crawlspace door to provide a tight, durable seal at the access point.

To address the crawlspace conditions and deliver a long-term encapsulation solution, we began with a Pro Cleaner hydrogen peroxide treatment to clean and treat affected wood surfaces. Next, we installed a partial interior perimeter drainage pipe in the areas where water was most likely to enter and routed it to a new sump pump basin. Inside the basin, we set a 1/3 HP sump pump and connected a dedicated discharge line to move collected water safely away from the foundation. With water control in place, we sealed and conditioned the space using the Crawlspace Doctor Exclusive Encapsulation System, creating a durable barrier against ground moisture and outside air. To keep humidity consistently in check, we installed a Sierra Watchdog NXT 85-pint dehumidifier, and we finished by building a custom PVC crawlspace door to improve access while tightly sealing the entry point.

To solve the problems in this home, we started by addressing the mold directly using our Pro Cleaner hydrogen peroxide treatment to clean and sanitize the affected surfaces in the crawl space. We then installed a partial perimeter drainage pipe system to capture groundwater and direct it into a new sump pump basin, where a 1/3 HP sump pump and dedicated discharge line now move water safely away from the foundation. To control humidity long-term, we added a Sierra Watchdog NXT 85-pint dehumidifier to keep moisture levels in a safe range. We also upgraded access with a custom-built PVC crawlspace door for a tighter, more durable seal. Because we identified structural concerns, we installed a steel beam and PowerPost floor supports to stabilize and strengthen the floor system above. Finally, we encapsulated the crawl space with an R-5 insulated system, including a heavy-duty 15-mil floor liner, to separate the home from the damp earth, improve energy efficiency, and create a clean, dry, and healthy environment underneath the house.

To solve the standing water and hydrostatic pressure issues, we began by treating the crawl space with our Pro Cleaner hydrogen peroxide solution to clean and sanitize surfaces affected by moisture and microbial growth. We then installed a full perimeter drainage pipe system to capture groundwater and direct it into a new sump pump basin, where a 1/3 HP sump pump now actively removes water from the crawl space through a dedicated discharge line away from the foundation. To create a long-term moisture barrier and protect the home, we installed the Crawlspace Doctor Exclusive Encapsulation System, sealing the crawl space from the damp earth and outside humidity. Because the prolonged moisture had compromised the HVAC ductwork, we replaced the HVAC supply ductwork, return ductwork, and register runs to ensure clean, efficient airflow throughout the home. Together, these upgrades eliminated standing water, relieved hydrostatic pressure around the foundation, and improved both the structural protection and indoor air quality of the home.

To solve the moisture issues around the home and protect the crawlspace long term, we started by installing a full-perimeter drainage pipe system to capture water before it could pool under or against the foundation. That drainage was routed into a dedicated sump pump basin, where a 1/3 HP sump pump now automatically collects and discharges water through a properly installed discharge line that carries it safely away from the house. Inside the crawlspace, we transformed the environment with an R-5 insulated encapsulation system and a durable 15-mil floor liner, sealing the ground and separating the home from damp soil and vapor. To actively control humidity, we installed a Sierra Watchdog NXT 85-pint dehumidifier, which maintains dry, stable conditions and helps prevent mold, wood decay, and musty odors. Finally, we custom built a PVC crawlspace door that won’t rot or warp and provides a tighter seal against outside air and moisture. Together, these steps turned a wet, vulnerable crawlspace into a clean, dry, and protected space that supports the health and stability of the entire home.

To solve the problems caused by hydrostatic pressure and standing water, we focused on drying the crawlspace and turning it into a controlled environment instead of a damp, exposed one. We began by removing the existing insulation, which had become damp and was trapping moisture against the floor system, creating ideal conditions for mold and wood decay. Once the insulation was out, we applied a Pro Cleaner hydrogen peroxide treatment to the exposed wood and surfaces, helping to clean and treat areas that had been affected by moisture and organic growth. After that, we installed a heavy-duty encapsulation system with a 15-mil floor liner, sealing the ground and isolating the home from the damp soil below. To further protect the space, we custom built a PVC crawlspace door that won’t rot, warp, or absorb moisture, and provides a tighter seal against outside air and humidity. Finally, we installed a Sierra Watchdog NXT 85-pint dehumidifier to actively control humidity levels and keep the crawlspace dry year-round. Together, these steps reduced the impact of hydrostatic pressure inside the crawlspace, eliminated standing moisture, and helped protect the home’s structure and indoor air quality over the long term.

To eliminate the standing water and prevent future moisture issues, we implemented a full-scale crawlspace drainage and structural support solution. We began by installing a full perimeter drainage pipe system to channel water into a newly placed sump pump basin, where a reliable 1/3 HP sump pump was added to actively remove collected water through a secure discharge line. To manage humidity levels long-term, we installed the Sierra Watchdog NXT 85-pint dehumidifier, which helps maintain a dry, healthy environment. To further protect the space, we installed a 15 mil vapor barrier to seal out ground moisture and blocked open vents to prevent humid air from entering. Additionally, we reinforced the crawlspace structure by installing a steel beam with a PowerPost floor support system, ensuring both moisture protection and long-term structural stability. This comprehensive solution resolved the homeowner’s water concerns and restored the integrity and health of their crawlspace.

To resolve the issues caused by standing water in the homeowner’s crawlspace, our team implemented a comprehensive solution designed to address both the immediate moisture problem and prevent future concerns. We began by soda blasting the affected areas to clean and remove mold and debris safely. A full perimeter drainage pipe system was installed to channel water efficiently into a newly placed sump pump basin, where a powerful 1/3 HP sump pump now actively removes excess water through a dedicated discharge line. To further protect the space, we installed our Crawlspace Doctor Exclusive Encapsulation System, sealing the crawlspace from outside moisture. A Sierra Watchdog NXT 85-pint dehumidifier was added to control humidity levels consistently. For structural reinforcement, we installed PowerPost floor supports and a new steel beam to stabilize weakened areas. We also custom-built a durable PVC crawlspace door to provide secure access, and replaced the HVAC return ductwork to ensure healthy airflow throughout the home. This integrated approach not only solved the standing water issue but also significantly improved the overall health and stability of the crawlspace and home.

To solve the homeowner’s humidity concerns, we installed a high-performance R-5 insulated encapsulation system designed to seal off the crawlspace from outside moisture and temperature fluctuations. This system included a durable 23 mil floor liner, providing a thick, tear-resistant barrier against ground moisture. To further regulate humidity levels, we installed the Sierra Watchdog NXT 120 dehumidifier, a powerful unit capable of maintaining optimal humidity in larger crawlspaces. Together, these components created a dry, controlled environment beneath the home, effectively reducing humidity readings throughout the living space and providing a long-term moisture mitigation solution.

To resolve the homeowner’s uneven floor issues, our team conducted a thorough inspection and identified that the underlying support structure in the crawlspace was failing to properly hold the weight of the home. We installed a heavy-duty steel beam to provide strong, centralized support across the affected areas. To further stabilize and lift the sagging floors, we installed adjustable PowerPost Floor Supports beneath the new beam. These supports allowed us to carefully level the flooring while providing long-term structural reinforcement. The result was a noticeably more even and stable floor, restoring both safety and comfort to the home.

To resolve the issue of sagging floors, our team conducted a thorough inspection and identified inadequate support in the crawlspace as the primary cause. We addressed the problem by installing a heavy-duty steel beam to provide strong, centralized support beneath the affected areas. To further stabilize and level the floors, we added adjustable PowerPost floor supports, which were securely positioned under the new beam to redistribute the load and lift the sagging sections back into place. This solution not only restored structural integrity but also significantly improved the overall stability and safety of the home.

To address the homeowner’s foundation concerns, we installed PowerPost floor supports to provide strong, adjustable reinforcement beneath the sagging areas of the home. These steel posts are designed to stabilize and lift weakened sections of the floor system. Additionally, we reinforced the existing floor joists by doubling them or using scab joists—attaching new lumber alongside the original joists—to restore their strength and structural integrity. This solution effectively stabilized the foundation, corrected uneven flooring, and gave the homeowner confidence in the long-term support of their home.
