Ox Foundation Solutions serves Huntsville, Alabama and North Alabama from an office in Madison. Its site says it has been keeping homes dry and stable since 2016.
The company lists foundation repair, waterproofing, crawl space repair and concrete services for residential and commercial properties. Its Huntsville page says technicians inspect the property to find the source of foundation and moisture problems before recommending repairs, and mentions underpinning systems for settling foundations. The pages reviewed do not mention helical piles by name, so they should be confirmed with the company.
Call the number in the directory or use the site to request an evaluation. If you want helical piles, ask whether the company installs them, which pile type is proposed and why, who engineers the repair, how depth and capacity are verified, and what the warranty covers. Ask for references in the Huntsville area.
