Financing for St. Louis homeowners

Acorn Finance Logo Jet Foundation Repair Partnership

As a trusted foundation repair company in St. Louis, we don’t hide financing costs in our quotes by offering "0% interest" loans. Instead, we have partnered with Acorn Finance to give you direct access to the best personal loan options on the market without inflating our repair costs.

Did you know?
Many contractors have to raise their prices by 10-20% to offer "0% financing" because of hidden dealer fees. We keep our prices honest and let you choose the financing that works for you.

    Copernicus v.

    Joanne C.

  • "Calder took the time to walk me through my options and gave me a clear, honest assessment of my situation. His deep understanding of foundation repair was evident, and he helped me avoid unnecessary costs—saving me thousands.

I highly recommend Jet Foundation Repair to anyone looking for real expertise and straightforward solution."

    Dusten C.

Jet

Jet was a good dog with a mischievous streak—she loved to dig. Whether it was in the backyard or at the beach, Jet would enthusiastically dig holes with her paws, creating little trenches and piles wherever she went. Despite her energetic nature, Jet was incredibly well-behaved. One of her most impressive traits was her discipline and that she thought “stay”, meant “freeze.” More than once, we felt guilty when we told her to “stay”, forgot, and then came back a long time later to find her in the exact same spot. We miss the good girl!
