Because our own areas of expertise are extensive, we don’t need to work with subcontractors often. But when we do, it’s because we have seen that the sub’s quality of work is outstanding. We maintain an exclusive network of trusted, specialized partners, and no one makes the list unless we are certain they are the premier expert in their area and can be trusted to maintain Big Rock standards. And Big Rock will always warranty a product install to the full warranty given by the subcontractor or supplier.
