Review 1
The back side of our house had settled 1 – 2-1/2″ in the 25 years we lived here. I called Antonio in October 2024 and he came out and gave me a couple estimates for 2 different options. He also told me he was booked through mid February. His bid was competitive, his timeframe to start in mid February was spot on, a lot of his equipment (hydraulic pumps, truck to inject polyurathane) looked brand new, his guys were professional and on time. The lead employee, Alejandro was great! He always checked in with me when he arrived and he always knocked on the door to inform me they were leaving. He was very patient as I was always asking questions about what they were doing, what was next, etc. and he was always patient answering my questions and even going to grab some of the devices being used to show me and help me understand more.

They installed 12 push piers on the back side of my house along with 15 Strong Jacks under the house. 8 of the push piers involved taking out dozens of deck boards. One board broke when taking apart, they replaced it with a new board and offered to stain the new board. You can’t tell that dozens of boards needed to be removed for the job as the deck looks like day 1. It is great to have our house back to level and really appreciated Antonio’s honesty as he used less polyurethane to inject under a slab than he expected so he had me deduct some off the contract amount.

Review 2
Andy assessed our project/floor/crawlspace, showed me the elevation measurements, and came up with a reasonable plan to raise the area of the house that had the lowest elevations. I had 4 companies come out, but Xalos provided a plan that made the most intuitive sense, not only when it came to the short-term repair, but also longevity (ensuring the posts wouldn’t sink again over time). The guys that did the work were great and the floor is noticeably more level. Grateful to have found a great, local foundation company – thank you, Xalos team!
