"Great people. They put down cloth to protect the floors from their boots. They tested the house before they started the work. They showed me results and explained them. They did the work, tested the house again and showed me the results again. BIG DIFFERENCE! They cleaned up everything afterwards, showed me and explained everything they had done and told me to call if I ever had any questions. Excellent!!"

"Ryan did excellent work. He explained everything so I could understand it. In just a few hours he rewired my electric heating system in my duplex. For the first time since I moved here (14 months) my heat is completely off !! I would give him 10 stars if it was possible, but here I would give him 5 stars."
