"Performed insulation work on our home. Vacuumed out the 25 year old blown in insulation on day one, then sprayed in foam for the whole roof to include the attached garage, and cleaned up afterwards. When there was confusion of the work they performed (my fault) Lee called me up to see if we were satisfied and was willing to do more to make me happy, but this was not necessary after he explained the work performed and I agreed that all was good. They came in on the week promised, delivered what was expected, and at a very competitive price. Also for veterans, they do give a veterans discount, so don't forget to ask."
