THE PRESSURE WASHING GUYS ARE AMAZING!!! Our driveway is concrete and was poured about 5 years ago. Since then our cars have leaked oil, battery acid and radiator fluid all over it. We came across The Pressure Washing Guys website and called and spoke to Brett about our situation. Brett was very knowledgeable about how to clean the crud off our driveway. He gave us a very competitive quote so we hired his team to do the job. Brett sent their best guy, Don, who drove to our house towing a trailer full of cleaning equipment. It took Don about three hours to wash, dry, wash, dry, etc. But when he was done our driveway looked AMAZING!!! We highly recommend using The Pressure Washing Guys to clean your driveway. Check out their website. They provide other services as well.
