Professional Foundation Repair and Concrete Leveling in Sonoma County

Homeowners across Sonoma County know that foundation issues can happen when you least expect them. From the hillsides of Santa Rosa to the coastal areas near Bodega Bay, the soil across the county shifts constantly. Clay-heavy soil expands with moisture and contracts when dry, while sandy soil can wash away during heavy rainfall. Over time, this movement can cause foundations to settle unevenly, walls to crack, and floors to slope.

Foundation Repair of CA helps homeowners and businesses throughout Sonoma County address these problems with proven foundation repair, concrete leveling, and crawl space encapsulation services. As a locally owned company, we take pride in providing dependable, long-lasting results with an emphasis on integrity and customer satisfaction.

We’re not just here to fix your foundation—we’re here to protect your investment for the future. Every project is handled by certified experts who use Foundation Supportworks® systems engineered to perform in California’s diverse soil conditions.

Concrete Leveling and Repair That Restores Safety and Value

Uneven or sinking concrete affects more than just the appearance of your property. It can create safety hazards, interfere with water drainage, and make outdoor spaces difficult to use. Foundation Repair of CA restores those surfaces using PolyLevel®, an advanced polyurethane lifting system designed to raise and stabilize concrete with accuracy and long-term reliability.

Why Homeowners Choose PolyLevel®

• Fast, clean installation without excavation
• Lightweight material that won’t add stress to the soil
• Water-resistant formula that won’t degrade over time
• Ready for normal use within hours
• Long-lasting stability with minimal maintenance

We use PolyLevel® to repair sidewalks, driveways, patios, pool decks, garage floors, and more. The process is simple: small holes are drilled into the concrete, the foam is injected beneath the surface, and the slab is lifted back into place. The result is a smooth, safe surface that looks better and performs like new.

We also provide professional concrete sealing to prevent future cracking, spalling, and erosion. Our technicians ensure every job is completed neatly, efficiently, and with minimal disruption to your home or landscape.

Crawl Space Encapsulation and Moisture Control

The crawl space is one of the most overlooked parts of a home, yet it can have a major impact on your comfort and safety. Moisture buildup, humidity, or poor drainage can lead to wood rot, mold growth, and structural decay. Foundation Repair of CA offers complete crawl space encapsulation solutions designed to keep your home dry, healthy, and energy-efficient.

Our Crawl Space Solutions

• Vapor Barriers: Create a sealed moisture barrier between your home and the ground.
• Sump Pumps and Drainage Systems: Direct standing water away from your foundation.
• Dehumidifiers and Air Purifiers: Maintain consistent humidity levels and improve indoor air quality.
• Structural Reinforcement: Strengthen weak or damaged floor joists and beams.

Encapsulation provides more than moisture protection—it helps lower energy costs, reduces musty odors, and prevents allergens from spreading into your living space. Whether your crawl space is damp, moldy, or structurally compromised, our team has the tools and experience to restore it.
