 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.
