Our Services

Foundation Repair Near You In San Rafael

Foundation Repair

San Rafael's combination of hillside terrain, older neighborhoods, and clay-rich soils makes foundation movement a frequent issue. Seasonal dryness followed by heavy coastal rains can cause the ground around your home to shift, leading to wall cracks, sloping floors, or sticking doors. Our experienced team pinpoints the cause and installs deep structural supports to stabilize your foundation and keep your home safe for years.

New Foundation Construction Near You In San Rafael

New Foundation Construction

Are you planning to build or expand in San Rafael? Whether you're working on a sloped hillside lot in the Dominican or infill property near Gerstle Park, your foundation needs to meet both seismic codes and soil-specific requirements. We design and build strong, code-compliant foundations that provide lasting support—no matter the terrain.

Crawl Space Waterproofing Near You In San Rafael

Crawl Space Waterproofing

Proximity to the Bay, high groundwater levels, and older drainage systems in San Rafael can lead to crawl space moisture, especially during the rainy season. We install high-quality vapor barriers and drainage systems to keep water out—preventing mold, wood rot, and structural decay while helping improve your home's indoor air quality and energy efficiency.

Concrete Repair Near You In San Rafael

Concrete Repair

Due to shifting soils and age, cracks and sinking in concrete driveways, patios, and walkways are common in San Rafael. We restore damaged concrete surfaces for a clean, safe, and functional finish. Our repairs address both the visible damage and the underlying soil conditions to ensure long-lasting results.

Drain Tile Installation Near You In San Rafael

Drain Tile Installation

Proper drainage protects your foundation in San Rafael's flood-prone and low-lying areas. If water pools near your crawl space or basement, we can help. Our team installs interior and exterior drain tile systems that redirect water away from your home, reducing hydrostatic pressure and minimizing moisture-related damage.

Crawl Space to Basement Conversions Near You In San Rafael

Crawl Space to Basement Conversions

Need more living space without changing your home's footprint? Many homes in San Rafael have crawl spaces that can be converted into full-height, finished basements. We manage the full process—from excavation and structural reinforcement to waterproofing and finishing—transforming underutilized space into a comfortable and valuable part of your home.

Concrete Leveling & Lifting Near You In San Rafael

Concrete Leveling & Lifting

Uneven or sunken concrete creates trip hazards and drainage problems around your property. In San Rafael, this often results from long-term soil movement or erosion. We offer non-invasive slab lifting solutions that raise the concrete back to its original position, improving safety and curb appeal without needing a full replacement.

Brick Foundation Repair Near You In San Rafael

Brick Foundation Repair

Many homes in central San Rafael and surrounding areas have brick or block foundations that can deteriorate over time due to moisture, seismic shifts, or soil instability. We carefully inspect for cracks, leaning walls, and failing mortar and then perform precision repairs to reinforce your foundation while preserving the home's original architecture.

I was skeptical that the cracks in my walls would close up, but they did. They were fair and explained the process better than every other company I had come out. I will definitely recommend to friends and family. Adam was very patient and helpful.

Adam Porter came out and took a look at my situation - was super honest and guided me in the right direction. I didn't need a large foundation repair and he gave me tips on how I could get the job done myself (since it ended up being a small one). Super honest crew - you don't see that much anymore.

Adam came out to look at a crack in our slab after we'd received several quotes in the $7,000–$10,000 range. I was completely surprised to learn we actually had a small fix that I could do myself! The honesty blew me away, and I'd recommend Stronghold if you're looking for someone to take care of your foundation issues.

I had an outstanding experience with Stronghold Foundation Repair from start to finish. Their team was professional, knowledgeable, and incredibly honest throughout the entire process. They took the time to thoroughly inspect my properties, explain the cause of the foundation issues in terms I could understand, and presented solutions without any pressure or unnecessary upselling. Communication was excellent, the crew arrived on time, kept the work area clean, and completed the project with exceptional attention to detail. It’s clear they take pride in the quality of their work and genuinely care about their customers. I now have complete confidence in the stability of my home’s foundation and the value of the repairs they performed. Finding a contractor you can truly trust isn’t easy, but Stronghold exceeded my expectations in every way. If you’re looking for a foundation company that is honest, reliable, highly skilled, and committed to doing the job right, I highly recommend Stronghold Foundation Repair. They have earned my trust, and I wouldn’t hesitate to use them again or recommend them to family, clients, and friends.

Adam came out and explained the issue wasn’t my foundation but my driveway. He was honest and said I could get someone else to do it cheaper and gave me a referral. I appreciated his honesty. I’d work with him again.
