The algae film that builds up on shaded walkways is not just ugly, it is slippery, and it is a common cause of falls around Florida homes. The north side of a house is usually worst, because the concrete never fully dries out. Sidewalks run $30 to $60, and a front walkway with the porch included runs $40 to $70. These are small jobs, so we normally bundle them with a driveway or house wash. That way you get one visit and one price instead of a minimum charge for fifteen minutes of work.
