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.

Big thanks to Mike. He was amazing to work with and didn't try to oversell us on anything. He kept it real and honest about what we needed, and most importantly, what we didn't. It's tough these days to find someone in this industry who will do that for you on the initial visit. I plan to refer everyone to Mike in the future.

Stronghold did a fantastic job on redoing my entire crawlspace support structure from initial quote to project completion. I was unsure how much of a job this would require to stop major settlement issues with my 1950's house. After a range of quotes, job proposals and research, Stronghold had the most reasonable scope of work at a competitive price. My choice did not disappoint, Strongholds construction workers were very professional and kept in the loop during the project. Work was performed in a timely manner with quality workmanship. I am vey happy with the work that was performed and would recommend them for foundation related repair work. Mike, Tyler and team are top notch.

We had Adam with stronghold come out to our house for a foundation inspection. One well known foundation company came out prior and told me I needed a foundation lift on one side of my house that would cost about $30k. The second company told me my foundation was fine and needed no repair after their inspection. Our final inspection was with Adam and he assured me that our foundation was level and did not need any repairs at this time. So thankful for honest people and companies. I will call stronghold again without hesitation for any future needs.

Fantastic experience with this company for my 102 year old house in midtown Sac. Im planning a big renovation and wanted to be sure my house was as level as we can get it beforehand. Prior to calling Stronghold, I had 2 other foundation companies come out. They gave me ridiculous estimates ($35-60k)- one wanted to enclose my entire basement and crawl space with plastic- totally not necessary with Sac’s climate. Stronghold sent Michael out- he was great. He came up with a very practical plan of using girders on jacks to support a heavy (long) wall for a fraction of the price of the others (less than $6k). What a relief. Manuel obtained a permit and answered questions I had as well. The working crew came in and got the job quickly. This is a no nonsense company and they will not sell you anything you don’t need. Highly recommend!

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 was friendly and professional, I was very impressed when he told me that no repair was needed at this time-- he carefully explained how foundation repair works, and discussed possible strategies moving forward.

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.
