Do you have a black or dirty driveway? We use high pressure surface cleaners to clean deep down into the concrete to remove dirt, mold, and mildew! We will post treat your driveway with our special concrete cleaner to loosen up the dirt or mildew that's deep down in the concrete. Once we treat the concrete we will go over it with a high pressure surface cleaner to reach deep down to make the concrete look like new again!, be careful who you hire to do your roof cleaning, there's a lot of fly by night guys that are not licensed and insured that don't use the right equipment for the job. Make sure they are a legitimate company!
