Our Crawl Space Solutions
We provide a complete range of crawl space repair and protection services that address the underlying causes of moisture and structural damage. Each project starts with a detailed inspection where we evaluate drainage, humidity levels, insulation, and structural integrity. Our team then designs a repair plan tailored to your home’s conditions and California’s unique climate.
Crawl Space Encapsulation
We use a 20-mil CleanSpace® liner that we extend up the foundation walls and combine with SilverGlo® rigid foam insulation to create an airtight seal. For total protection, we also wrap the bottom of pier post assemblies and concrete sections with CleanSpace liner and seal them with specialized tape to ensure no moisture can reach critical support structures.
Crawl Space Drainage Systems
For severe groundwater infiltration, we install the TripleSafe™ Sump Pump System, which includes three levels of protection: a primary pump, a high-volume secondary pump, and a battery-powered backup for power outages. In a recent San Mateo project, we paired this with our patented WaterGuard® interior drainage system to capture water at the foundation’s edge before it could ever reach the living space
Air Purification and Dehumidification
Our Sedona Dehumidifiers are equipped with condensation pumps to actively pull moisture out of the unconditioned air. In both San Mateo and Pacific Grove, this system successfully eliminated persistent, damp odors and transformed the crawl space into a dry, well-regulated environment.
Structural Reinforcement
If your floors feel soft, uneven, or sagging, we install heavy-duty crawl space jacks to provide permanent structural support. This solution stabilizes the floor system and prevents further settlement or shifting.
Crawl Space Insulation
We remove damaged or wet insulation and replace it with moisture-resistant materials that help improve comfort and reduce energy costs. Proper insulation also helps maintain steady indoor temperatures throughout the year.
