Damyans Construction LLC is a concrete and helical pier installation contractor in Hopkins, Minnesota, in the Minneapolis area. You can reach the company at 612-987-1913. Contact the company directly to confirm current services and the areas it covers.
For a contractor that does both concrete work and helical piers, ask whether the piles are installed by its own crew, what torque or depth criteria are used, whether engineered drawings are provided for permits, and whether it carries the licensing and insurance your city requires.
Before signing, get the scope, pile specifications and permit responsibilities in writing. Comparing at least two written quotes makes differences in pile size, depth and included engineering easier to see. Ask for references from recent projects similar to yours.
