My husband and I want to thank you for doing the right thing. It is so rare in this age for business people to be fair and responsible. We are very thankful for your good ethics and for all the good work your company did for us. Every person that worked in our house was courteous and hard working. We were also impressed that the crews kept our home clean by using floor covers and shoe covers. Thank you again for being fair with us.
