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. 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.

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

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