Grime, mildew and stains build up a little at a time until one day the outside of your property looks years older. House Washing for Wood Siding in Wisconsin brings it back, usually in a single visit. On wood siding, the method we use is soft wash.
How we clean it
Cleaning solution: A mild house-wash mix; an oxygen-based cleaner when the wood will be stained.
Cleaning wood siding safely
Painted and stained wood siding grows mildew and loses its finish faster on the shaded and weather-facing sides. A soft wash cleans it without raising the grain, and is the usual first step before repainting or restaining.
Avoid: High pressure that raises fibers, gouges the wood or strips sound paint unevenly.
How often: Every 1-2 years, and before every repaint.

Serving Wisconsin and nearby towns
In Wisconsin, snow and slush that sit against the house leave a band of grime and mildew along the lower siding, and shaded north walls stay damp long after the thaw. A spring soft wash removes winter grime before it bakes on over the summer.
Much of Wisconsin has hard water. Sprinklers and misters leave white mineral spots on walls, windows, fences and pool tile, and those spots need a mineral-safe cleaner, not more pressure.

Is house washing for wood siding safe for my plants and pets?
We pre-wet plants and lawns, keep cleaning solutions diluted to what the surface needs, and rinse landscaping again when we finish. Keep pets and children inside until surfaces are rinsed and dry.
How often should I schedule house washing for wood siding?
Every 1-2 years, and before every repaint. Shade, nearby trees, humidity and heavy traffic mean more frequent cleaning; sunny, dry spots can go longer. Our free cleaning frequency tool gives a recommendation for your climate.
What if it rains on the day?
Light rain doesn't stop most washing, but heavy rain, high wind, lightning and freezing temperatures do. If the weather isn't right, we reschedule at no charge. Our work is backed by a satisfaction guarantee.
