Not Your Ordinary Seattle Pressure Washers

Understanding Our Seattle Exterior Cleaning Method

Our building or house washing methods are designed to protect your property. We use bleach and other solutions for a soft wash approach, reserving high pressure for concrete surfaces only. This method prevents damage to window seals, gutters, and other sensitive areas. Plus, our use of bleach ensures that moss and algae are completely eradicated, preventing their unintended spread.
