Our Services

Foundation Repair & Underpinning

Foundation repair is crucial for maintaining the integrity and safety of a building, as a damaged foundation can result in structural damage, cracks in walls and floors, and even collapse.

New Foundation Construction

A well-built foundation is essential to the stability and safety of any building. At Stronghold Foundation Repair, we have experience building new foundations for a variety of structures.

Crawl Space Waterproofing

Crawl space waterproofing is an essential step in protecting your home’s foundation from water damage. A common approach to crawl space waterproofing involves installing a vapor barrier on the floor and walls.

Concrete Repair

Concrete is a durable material, but it is not immune to wear and tear caused by factors such as freeze-thaw cycles, heavy traffic, and exposure to the elements. Repairing concrete surfaces is essential to prevent further damage and to maintain their structural integrity.

French Drain & Drain Tile

A drain tile system, also known as a French drain, is a type of waterproofing system that helps to protect the foundation of your home by redirecting groundwater away from it. It consists of a buried, perforated drainage pipe surrounded by gravel, and covered by soil.

Crawl Space to Basement Conversions

Crawl space to basement conversions are increasingly popular among homeowners because of the added value and functionality they bring to a property. Benefits include increased living and storage space, improved energy efficiency, and increased home value.

Concrete Leveling & Lifting

Polyjacking is a modern and efficient technique used in concrete leveling that involves injecting polyurethane foam underneath an uneven concrete slab. The foam expands to lift and level the slab without the need for heavy equipment or excavation.

Brick Foundation Repair

Over time, the foundation of a structure may settle or shift, causing cracks and damage to the brickwork. This can lead to water infiltration, structural instability, and even collapse. To prevent these issues, it is important to repair foundation damage as soon as possible.

 Trustindex verifies that the original source of the review is Google. 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.

 Trustindex verifies that the original source of the review is Google. 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.

 Trustindex verifies that the original source of the review is Google. 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.

 Trustindex verifies that the original source of the review is Google. 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!

 Trustindex verifies that the original source of the review is Google. 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.

 Trustindex verifies that the original source of the review is Google. 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.

 Trustindex verifies that the original source of the review is Google. 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.
