American Helical LLC

American Helical LLC is a third-generation general contractor that works in California, with a focus on accessory dwelling units, decks and foundations. Its site highlights ADU construction in the Modesto area and lists a California contractor license number.

The listing places the company in British Columbia, which does not match the California focus on the website, so the location should be verified. Helical piles are mentioned only lightly on the pages reviewed, so it is unclear how central pile installation is to the business. The site includes project videos and an Instagram account.

Before hiring for helical piles, ask whether the company installs them itself or subcontracts, which pile brand and sizes it uses, who provides engineering for permits, and how torque is recorded. Confirm the contractor license in your state or province through the licensing board and ask for references on pile projects.
