Bad business practices.
If you enjoy being swindled into a contract with these guys feel free to consider their services. As it is, Wilson and the employees at this company are inconsiderate and enjoy lying to get their way. After signing up via a WSB contest, Wilson Insulation tried to get the entrants to sign up for junk mail. When I called them on it, they were extremely inconsiderate and rude. The problem was so severe and crooked, it was escalated through the WSB executives and the matter was handled. Stay away, do more research before you call this company. Funny, I don't see them advertised anymore on WSB... wonder why?
