Project Details
The resident’s sewer leak issues returned despite the sewage pipe being previously fixed. Another crawl space company attempted to treat the area just by laying lime solution and lava rock, but their solution proved ineffective. Frustrated and seeking a lasting solution, they reached out to us for a thorough inspection and quick resolution of the issue.
Our team arrived promptly, preparing to tackle the crawl space’s sewer leak. In just one day, we transformed the neglected, damp area into a clean, efficient, and secure part of the home. The residents were delighted with the results, especially knowing their home was now protected from moisture issues.
To ensure complete satisfaction, we guaranteed additional work at no extra cost if the crawl space still smells after our initial remediation. Thanks to our comprehensive sewer leak remediation, the home is now odor and moisture-free.

Project Details
A family home had a hidden problem. Beneath their home was a crawl space, dark and damp, plagued by mold and excessive moisture. Concerned about the health and efficiency of their home, they reached out to us for help.
The team arrived promptly, ready to tackle the challenges lurking below the house. They began by removing all compromised materials, including the old vapor barrier, soggy insulation, and even remnants of animal waste. With determination and care, they thoroughly sanitized the area, making it safe and clean once more.
To combat the persistent mold, they treated all the wooden surfaces with a powerful fungicide solution, effectively eliminating the mold on contact. To ensure the mold would not return, they applied a primer, sealing the wood and safeguarding it from future growth.
Addressing the moisture issue, the team installed a French drain around the entire perimeter of the crawl space. They added a catch basin and sump pump to keep the area dry and free of standing water, creating a more stable environment beneath the home.
Understanding the importance of a rodent-free space, they meticulously sealed all potential entry points. They also addressed air leaks around plumbing, ducting, and electrical penetrations, enhancing the home’s energy efficiency. The final touches included installing a new vapor barrier, wrapping water supply lines, and insulating the floor with high-quality insulation.
To further improve the crawl space, they sealed all air duct joints with mastic paste, preventing any air leakage and ensuring proper insulation for the ducts. They installed a brand-new crawl space door and built a sturdy access cover, securing the area for future inspections.
As a final measure of protection, the team introduced a one-year rodent protection plan. They placed traps and scheduled regular monitoring every three months, ensuring the family could rest easy knowing their home was well-guarded.
The family’s crawl space, once a source of worry and potential danger, is now a clean, dry, and secure area, thanks to the diligent work of the professional team. The house stands stronger and healthier, ready to shelter its inhabitants for many more years to come.
