I had them do work on my house a couple of years ago. I like that they weren't out to make my…read moreentire house level but only the worst areas. If they had done that it would have wrecked the plumbing not to mention that I would be left to repair the flooring. Recently, one side of the house started to sink again. They came back out and leveled it back up for free since it was under the lifetime warranty and I kept up with the maintenance. The lifetime warranty makes it worth the expense. Luis is amazing and I trust him.

Luis has been the best with post-work care. I had the entire front of the house lifted in 2022, and…read morehe's been extremely responsive and helpful in the time since (it's now almost 2025). They take care of you after the job, and I don't ever get the sense that they're just in it for the money. They obviously care about their customers and will do what is right, not just what is profitable.

Called to request a foundation inspection, as the home is 30 years old, we have some very minor…read moretile cracks, and do see some seasonal movement in door openings (mostly one upstairs one). Some brickwork is cracked around suspended arches and cornerstone decorative pieces (e.g. above garage doors) but obviously has been for decades. I specifically called Cornerstone because I wanted a serious contractor who does actual poured footings, not that stacked cylinder mess that could actually crack your foundation worse as they use your house for the jack leverage. Dave was on time, courteous and (given that our appointment was in the middle of the Viral Apocalypse) understanding that I was working from home instead of 'off' for the day of our appointment. We spoke for a bit, he outlined everything well and asked pertinent questions about my reasons for calling, then got down to work inspecting...and recommended no work be done at this time. I offered to pay a service charge but he said that wasn't necessary. We did follow up on the phone briefly (I was busy when he was finished) and I am strongly considering coming back to them for some drainage improvements here and there as precautionary measures. Thanks for the time and professionalism.

I got 4 estimates. Pinnacle, Olshans, Groundworks and Williamson…read more Williamson was the only company offering to adjust the existing peirs. They also added new piers and even found 2 piers missing the previous company charged for but didn't install. They were easy to contact and follow up was good.

Originally, we were told the job would two days, but they brought 6 workers plus a crew leader. The foundation work was completed in one day. The crew cleaned up our yard and my neighbor said you could not notice that extensive work had been done. The price was very competitive and I will recommend them to others if asked.

Great work and a nice price. I have recommended NTX many times to my mortgage clients!read more

Fantastic Job Leveling My Shed!…read more I had Fortress Foundation Repair Systems come out to level my storage shed, and they did an amazing job. This 30-year-old shed was noticeably uneven due to soil shifting, but they got everything straightened out quickly and efficiently. The entire team was friendly, including Steve, who came out promptly and gave me an estimate, to the in-house office staff, and the crew that came and actually performed the work. They were on time, and explained everything clearly. Now the shed sits perfectly level, and the whole structure feels more solid. They also cleaned up the area afterward, which I really appreciated. Pricing was very fair for the quality of work. I highly recommend Fortress Foundation Repair Systems. Professional, reliable, and great results! -- Tommi

BUYER BEWARE!!!! ‼…read more Six years and $20,000 paid and they still haven't finished the work they were paid to do. They talk great in the beginning. We thought we did our due diligence, but they failed over and over again to do what was promised. Shoddy work other companies shocked to see when we asked for quotes to fix what we already paid for. They continually pass you from one person to another hoping you will just give up. Not only is our foundation still not fixed, they have caused extensive additional damage to our home, came onto our property while we were out of town with no notice and no authorization and performed work we did not even authorize. Do NOT use them. You may end up lucky but for the amount you will pay, it isn't worth the risk. At this point, what did we even pay for?! It would be great is CATHY HOOD or MAT LEVITSKY, please do what you are required to do. We are waiting for your return call.
