What affects the price

When you call for a quote, the final number depends on a few specific factors. We look at the total square footage of the areas being cleaned and the current condition of the surfaces. Deep stains, heavy organic growth like algae or thick moss, and the level of accessibility all play a role in how long the job takes. We also consider the type of material, whether it is delicate siding, concrete, or wood decking, as each requires different equipment and solutions. Exact pricing confirmed free on the call.

About this service

House washing uses a specialized soft-wash technique to clean siding, stucco, or brick without damaging your home. This process relies on gentle pressure and cleaning agents to safely remove mold, pollen, and dust. You need this when your exterior walls look dull or green growth appears near the roofline. Costs are based on the height of your home and total square footage.

Summer heat is ideal for pressure washing, as surfaces dry quickly and cleaning solutions work efficiently. It is the peak season for hosting guests and enjoying your outdoor living areas like patios and decks. Keeping these spaces clean makes them much more comfortable for your family and friends. Contact us to get your surfaces ready for summer.
