The great yelp reviews were correct! SO we have a cat pee issue. Our cat has peed in a couple corners of our house. Well....we have dark carpet and can't tell when she pees so it soaked into the carpet/pad AND wooden boards that tack the carpets. The smell was unbearable. Rob came and cleaned the bedroom and living room. Carpet looked great but the cat pee smell didn't go away. Called him to come back and he came the next day. HE tore back the carpet and saw soaked tack boards with cat pee and the pad was not drying which was causing the smell to linger. HE replaced the pad with a waterproof pad, removed the soaked tack boards and even sealed the concrete/baseboards with a floor sealant. SMELL IS GONE. I gave up and Rob told us that he would do ANYTHING he could to get the smell out or $ back. AND he did! Thanks Rob! We will never use anyone else!
