"Our AC was running nonstop. Cardinal blew in new insulation in one afternoon and our electric bill dropped almost $120 the next month. The crew was clean, polite, and fast."
"Got three quotes — Cardinal was the most thorough and the fairest price. They actually showed me photos of my attic before and after. Highly recommend."
"We can finally use our upstairs bedroom in the summer. The difference is night and day. Professional from the first call to the final cleanup."
