Environmentally Safe – Our Powerwashing Services include applying environmentally safe cleaners to the entire area to remove mildew, mold, algae and dirt. Hot water powerwashing is then used to clean surfaces thoroughly without the risk of damaging the surface area. Once the powerwashing is completed, the entire areas are rinsed. We recommend treating surfaces like pressure treated wood and cedar with a sealer or stain once they have been cleaned. Your home is your biggest investment.
