I just bought my first home a beautiful condo but the previous owner had a dog for years. We tried to clean the carpet ourselves but it still smelled like dog. So I searched the internet for a carpet cleaner that could get the pet odor out. Chicagoland carpet cleaners came up in my search. I called and got an estimate over the phone it was very reasonable and the technician wanted to wait until he could check the Capet to determine if I needed to spend as much money. I have to say they did a superb job, and I will be sure to call them again!
