Very disappointed about the luck of communication, paid for wall insulation back in August after a few phone calls I was told that the work would start at beginning of November, as today 1/11/2018 nothing happened, after another phone call I was told the work would start I January 2019 because they do not want to leave the scaffolding on for the December month if I knew this would had happen I would I never gone for it
They are a disgrace taking your money and stop communicating
