  • "Your crew was more than great! Our 1926 house (built by my grandfather), with not much attic space, needed to have all blown insulation removed, so that we could install an air conditioning unit, and seismic enhancements. They were on time, cleaned up really well. Our contractor was so impressed. Paul S. Wheeler, Architect Maureen M. Wheeler Architect"
