Google search on “helical pile” will reveal plenty of manufacturers and installers. However, many of them don’t have small enough equipment to do residential installations, or the contractors are so used to doing heavy-duty work that they may not bother with small residential projects. I went with Techno Metal Post (technometalpostusa.com) — and even bought a franchise — because they are a good fit for my business. Their helical piers are accessible, both in cost and logistics. Most other helical piers require a skid-steer or an excavator to provide the power for their drivers, but Techno Metal Post uses proprietary equipment that’s small enough to fit through a gate, climb steps, and even drive onto an existing deck to retrofit footings (below), say to support a new hot tub.
