    foundation leveling
    $167,000

    THE WORST. Did a terrible job, allowed to remedy and caused intense damage. Could not manage a simple concrete slab porch even. Everything they did must be redone and the damages are in excess of $157,000. Check out builtstrongruinedmylife dot com.

    We have a work done by Builtstrong construction and all work was completed on time and to our satisfaction completely.
    The assosiates that did the work at our home were professional and showed up on time each day. They were in our home for approxmetly 1 week and we did allow them to be at our home while unattended with no issues what so ever.
