Professional House Washing
Restore your home's curb appeal with our safe and effective soft-wash technique. We completely eliminate algae, mold, dirt, and bacteria without ever risking damage to your siding or paint.
The Danger of High-Pressure Washing
Many homeowners and inexperienced contractors try to blast away green algae and dirt using high-pressure wands. This is a costly mistake.
Water Damage Behind Siding
High pressure forces water behind vinyl and aluminum siding, leading to trapped moisture, unseen mold growth, and eventually, structural rot.
Surface Destruction
Pressure washing can easily strip paint, blast away the protective UV coating on vinyl siding, and permanently etch brick and stucco.
That's why Keystone Power Washers uses the industry-standard Soft Wash Method.

We treat the root cause.
Our soft wash algaecides kill the spores that cause the green and black stains, ensuring a clean that lasts 3x longer than pressure washing alone.
Our Signature 4-Step Soft Wash Process
We don't cut corners. Our meticulous process ensures your home is safely cleaned and your landscaping is fully protected.
Site Preparation
We start by thoroughly watering all surrounding plants, shrubs, and grass. We tape off keyholes, cover electrical outlets, and ensure windows are fully closed.
Solution Application
Using low pressure (less than a garden hose), we apply our proprietary, biodegradable cleaning solution from the bottom up to prevent streaking.
Dwell Time
We allow the solution to sit for 5-10 minutes. This allows our algaecides to break down dirt, spider webs, mold, and algae at the molecular level.
Safe Rinsing
We perform a high-volume, low-pressure rinse from the top down, washing away all contaminants and leaving a pristine finish. Finally, we do a post-rinse of all vegetation.
