Our Services

Foundation Repair Near You In Martinez

Foundation Repair

Martinez's hillside terrain and clay-heavy soils—combined with seismic activity and seasonal weather changes—can cause foundations to shift, crack, or settle. If you notice signs like sticking doors, uneven floors, or cracked walls, these may indicate foundation movement. Our experienced team at Stronghold Foundation Repair identifies the root cause and installs deep structural supports to restore stability and prevent further damage, protecting your home and its value.

New Foundation Construction Near You In Martinez

New Foundation Construction

Planning to build or expand in Martinez? Whether constructing a custom home near Alhambra Valley or adding onto a property in a historic neighborhood, your foundation must be built to handle local soil conditions and building codes. We provide strong, code-compliant foundation systems that ensure your home is structurally sound for the long haul.

Crawl Space Waterproofing Near You In Martinez

Crawl Space Waterproofing

Bay Area fog, rainfall, and sloped lots in Martinez can contribute to crawl space moisture—leading to mold growth, wood rot, and poor air quality. We install moisture barriers and drainage systems to protect your crawl space from water intrusion. The result is a drier, healthier environment that improves energy efficiency and extends the lifespan of your structure.

Concrete Repair Near You In Martinez

Concrete Repair

In Martinez, soil shifting, moisture, and aging surfaces commonly lead to cracked or uneven concrete. We repair driveways, patios, sidewalks, and steps, restoring appearance and safety. Our repair methods address the damage and the underlying soil movement to provide long-lasting results that help prevent future issues.

Drain Tile Installation Near You In Martinez

Drain Tile Installation

Water pooling near your home's foundation is a serious concern in areas with poor drainage or hillside runoff. We install interior and exterior drain tile systems that direct water away from your foundation, reducing hydrostatic pressure and helping to keep basements and crawl spaces dry and protected year-round.

Crawl Space to Basement Conversions Near You In Martinez

Crawl Space to Basement Conversions

Need extra living space without changing your home's footprint? Many homes in Martinez are built with crawl spaces that can be transformed into full-height, finished basements. We manage the full conversion process—excavation, structural upgrades, waterproofing, and finishing—turning unused space into a functional, comfortable part of your home.

Concrete Leveling & Lifting Near You In Martinez

Concrete Leveling & Lifting

Uneven or sunken concrete isn't just unattractive—it can be a safety hazard. In Martinez, shifting soils and aging foundations can cause sidewalks, driveways, and patios to settle. Our minimally disruptive slab lifting process restores a level surface, improving safety and curb appeal without needing full demolition.

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.
