Rain, mud, algae, tire marks and seasonal grime build up on Chilliwack driveways faster than most homeowners expect. Here’s what’s really going on.
Concrete driveways darken faster than most homeowners expect, and it’s rarely just dirt. Tire marks, oil residue, organic staining from nearby trees, and a fine layer of algae all combine to gradually shift a driveway from light grey to a dingy, uneven tone.
Because concrete is a durable, porous hard surface, it responds well to controlled pressure washing — technique and the right nozzle distance matter more than raw power, since uneven pressure can create visible “striping” if it’s rushed.
Most Fraser Valley driveways benefit from an annual cleaning, with shaded or tree-lined properties sometimes needing it more often to stay ahead of organic buildup.
