Posted on Dana SmithTrustindex verifies that the original source of the review is Google. Update 4/12/26 The company reached out to us, came to our home and made a plan to properly lift our house. The work was done in a timely manner and we had a much better experience with them this time around. We are very happy with how things turned out. Awful company. We paid over $38,000 to raise our foundation 1.5”. It started cracking and they were unable to do what they said they could. They “stabilized “ it and left with our savings. It was the biggest waste of money and I suggest you go elsewhere. Garbage. Our house feels like it’s sinking more.Posted on Longitude 120 Engineering & DesignTrustindex verifies that the original source of the review is Google.

So I had some work done by r and r back in 2019. I had six piers put in and really enjoyed Corey the owner… fast forward to 2026 and the other part of my house started having weird sounds and a crack in my ceiling… I live on a hillside and tons of water comes my way and a user error with a downspout may have caused more issues… I made an appointment to have him come Out and do an inspection with a bid…. It’s pretty rare these days to not feel like you have gotten taken… Cory did all the measurements and well it appears the house is just settling. The house was built in 1980 by the original owners and was definitely not built straight. Anyway… Cory literally put me at ease and said. “Let’s just keep these measurements and check them out in a year or so. “He could have easily have just said… “yup. You need six piers….” He didn’t. I highly recommend r and r foundation… thanks for being honest… it goes a long way! Also… when I do need the work done… I, of course, will be using them!Posted on Philip KoglerTrustindex verifies that the original source of the review is Google. House built in 1913 did not disappoint with challenges with a leaking foundation into the basement. But, R&R came through and I am able to feel confident that any further water issues are no longer. If the opportunity presented itself, I would hire them again.Posted on Julie CarlsonTrustindex verifies that the original source of the review is Google. I had them come out to my house to look at an issue of water seeping into my garage which is built into a hill. For reasons that have nothing to do with them, I didn't end up getting the work done. However of the four companies I had look at it, R&R's assessment was easily the most thorough. They are the only one that did any significant inspection outside of the building rather than just inside the garage and their prices were comparable to the other companies I checked out.Posted on Andrew HarpsterTrustindex verifies that the original source of the review is Google. Had R and R do some work on our older home that needed an update to the crawl space foundation posts a few years back. Work was accomplished in a timely and professional manner. Now in 2025, we are selling our home in a slow market and want to upgrade. We need to show the new buyers the application to transfer the foundation warranty ahead of the inspection in a few days as a show of good will to close the home. R and R's marketing manager, Jordan, was able to accomplish this promptly within one day for us and really set us up well to help close our home. While the foundation repair was important, it was years later, being able to connect with R and R again, and show the new buyers the work they had done and that it was done by a reputable company, that helped seal the deal.Posted on Christine FreitasTrustindex verifies that the original source of the review is Google.
