"We had Hollis come to our lake house for a possible mold problem in our crawlspace. No problem there but he left a packet with us, which included info about sunhouses. We thought that sounded good for our house in town, and it is! We liked the way Hollis explained things. Of course it sure helped that he is a Purdue Graduate! We really appreciated his honesty in telling us that nothing needed to be done at the lake house. My husband was VERY impressed with Dave, the man who installed our sunhouses. My husband says Dave did an excellent job, he was very neat and careful. He cleaned up the areas really well. He even washed the basement window for us."
