R & K Were contracted to insulate our 500 Sq ft garage as a retrofit in a new home. The two member team showed up on time. They drilled 2" hole between the 2x4 studs into the dry wall. the blew cellulose insulation in to the walls. Everything was done to prevent any damage to the interior of the garage. They were assigned to insulate the roof of the garage but it was not possible to do this. I contacted the Sales rep and Luis immediately re-quoted the job at a lower cost and the crew insulated the celling of the garage. I had received four quotes and R & K was competitive. I would recommend this company.
