When we handle house washing in O'Fallon, MO, it comes down to three things: protecting your plants and property, cleaning with the right method, and walking the job with you at the end. You may also hear it called exterior house cleaning, house power washing or siding cleaning.
The right method for the job
Is it time for house washing?
- Green or black film on the shaded sides of the house

Where the grime comes from
- Mildew and algae in shade and humidity
- Rain splashing soil onto the bottom courses
- Pollen, dust and road grime
- Spiders and insects under the soffits
Easy upkeep between cleanings
- Rinse small areas with a garden hose and a soft brush on an extension pole
- Use a mild detergent made for siding, not household bleach straight from the bottle

Humid summers in Missouri grow green algae and black mildew on the shaded sides of homes, especially on vinyl and painted wood. A soft wash kills the growth rather than just knocking it off, so the siding stays clean longer.

House Washing: frequently asked questions
How much does house washing cost in O'Fallon, MO?

Do you use high pressure for house washing?
House Washing is done with soft wash. Low pressure and the right solution remove growth and dirt without damaging the surface, and the growth takes longer to come back.
Is house washing the same as exterior house cleaning?
Yes. Exterior house cleaning, house power washing or siding cleaning are other names for house washing. Whatever it's called, we use soft wash and match the pressure and cleaning solution to the surface.
Is house washing 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?
Every 1-2 years. 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.
