I had a garage that I demoed what was left with the foundation footings I just could not believe how much he ripped that up four loads in the truck graded it out he did a beautiful job. I don’t know what else to say. I would recommend him to anybody very professional called him, answered his phone every time very reasonable Slade and his partner two hard workers. He did everything I asked cleaned up put my fence back up and completed in one day beautiful thank you very much, Slade."

"Alex was amazing!! We had a crack in our foundation that another company attempted to repair numerous times. We were fortunate enough to hear about ProSeal and I am happy to report not only did Alex repair the crack to near perfection but the work was done timely, neatly and his customer service skills are top notch. I would HIGHLY recommend ProSeal for all of your foundation needs."
