House Washing for Vinyl Siding is one of the jobs we do most often in Colorado. Typical jobs cost $300-$700, and you approve the price before we begin. For vinyl siding, that means soft wash.
Method and pressure
Cleaning solution: A diluted sodium hypochlorite (house wash) mix with a surfactant, applied low and rinsed thoroughly.
What to know about cleaning vinyl siding
Vinyl is the most common siding in the U.S. and cleans up well, but the panels overlap. Water driven upward under the laps can soak the sheathing behind them, so siding is rinsed at a downward angle and never blasted from below.
Avoid: High pressure aimed up under the panel laps, and hot water on dark-colored vinyl, which can warp.
How often: Every 1-2 years, more often on shaded north walls.

House Washing for Vinyl Siding in Colorado
In Colorado, strong sun fades siding and paint, and winter grime builds up along the bottom of walls. A gentle spring wash removes it without stripping a finish that the sun has already weakened.
Much of Colorado 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.
Some cities in Colorado limit outdoor water use, including washing hard surfaces with a hose, especially during drought declarations. Pressure washers use far less water than an open garden hose, but rules vary, so it's worth checking your city's current restrictions. Wash water should also be kept out of storm drains.

Do you use high pressure for house washing for vinyl siding?
For vinyl siding: low pressure, typically under 500 PSI at the wall, with the cleaning solution doing the work. What we avoid: high pressure aimed up under the panel laps, and hot water on dark-colored vinyl, which can warp. The cleaning solution does most of the work, followed by a gentle rinse.
Is house washing for vinyl 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 vinyl siding?
Every 1-2 years, more often on shaded north walls. 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.
