How Often Should You Pressure Wash Your Home in Castle Rock, CO?
It's one of the most common questions we get from Castle Rock homeowners: how often does this actually need to happen? The honest answer is "it depends on the surface," so here's a straightforward breakdown by area of your property.
Home Siding & Stucco — Once a Year
Most homes in Castle Rock need a full exterior soft wash once a year. Homes with north-facing walls, heavy shade from trees, or locations near open space tend to develop algae and mildew faster and may benefit from cleaning every 8–10 months instead.
Driveways & Concrete — Once a Year, More If You Have a Long Winter Season
Mag chloride de-icer used on Douglas County roads gets tracked directly onto driveways all winter. Most homeowners see the best results cleaning concrete once a year, ideally in spring after the last treatment of the season.
Decks & Patios — Once a Year, Timed Before Staining
If you plan to stain or seal your deck, cleaning should happen shortly before that project — otherwise, once a year in spring is a good default to prevent gray weathering and mildew buildup.
Fences — Once a Year, Twice If Heavily Shaded
Shaded fence lines, especially in wooded or north-facing yards, can develop algae fast enough to need attention twice a year. Sun-exposed fences typically only need an annual clean.
The Simple Rule of Thumb
If you can't remember the last time it was cleaned, it's probably time. Staining, algae, and mag chloride residue are much easier (and cheaper) to remove before they set in for multiple seasons.
