Driveway and concrete cleaning in Knoxville: what to know

Concrete in the Knoxville area stains from the edges in. Red clay washes onto the low end of the driveway, shaded walkways go green with algae, and oil drips collect under parked cars. A surface cleaner lifts general grime evenly, but clay, rust and oil stains usually need a pre-treatment or a post-treatment. HomeBlue's Knoxville figures put a two-car driveway of about 800 square feet at $140 to $250, and a 1,600 square foot driveway at $280 to $500. Hot water for heavy oil can add 10 to 15 percent. Adding the walkway and patio to the same visit usually costs less per square foot than booking them separately, since many companies charge a job minimum. Many driveways slope to a street, a ditch or a storm inlet. Knox County's ordinance counts washwater on driveways that drain to the storm system as an illicit discharge, so ask the provider how they will handle runoff from detergents and oil.
