Illinois weather is tough on home exteriors. Humid summers encourage mildew and algae on shaded siding, spring pollen leaves a film on every surface, and winter road salt and grime build up on lower walls, walkways and driveways.

For most homes in the Chicago area, washing the house exterior once a year is a good rule of thumb. Late spring, after pollen season, is a popular time. Homes under heavy tree cover, near water, or with north-facing walls that stay damp may need it more often.

Signs it is time for a wash include green or black streaks on siding, dull or chalky paint, dark stains on the roof, and slippery patches on walkways.

Siding, stucco and roofs are best cleaned with low-pressure soft washing. Concrete driveways and sidewalks can handle higher-pressure power washing.
