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.

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

Professional house washing involves using specialized equipment to gently remove dirt, mold, and mildew from your siding. The final cost depends on the size of your home, the material of your exterior, and the level of buildup present. A larger home or one requiring extra attention usually requires more time and supplies.

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.
