Soft Wash Pressure Washing

All of our house wash services is a soft wash pressure washing

Our Soft Wash Process

Our soft wash residential pressure washing process begins by pre-wetting your home's exterior and surrounding landscaping with clean water. We then apply a carefully measured cleaning solution that combines surfactants (professional-grade soaps) with sodium hypochlorite (bleach) at safe, controlled concentrations. This powerful yet safe mixture is what makes soft washing so effective at killing mold, mildew, and algae at their source.

We allow the cleaning solution to dwell on your home's exterior for 10-15 minutes, giving it time to penetrate deep into porous surfaces, break down organic growth, and lift years of accumulated dirt and grime. During this dwell time, the surfactants work to surround and suspend dirt particles, while the sodium hypochlorite kills mold and mildew spores, destroys algae, and eliminates the organisms that cause those unsightly black streaks and green stains common on Portland homes.

After the solution has had adequate time to work, we thoroughly rinse your home's exterior with low-pressure water, revealing a clean, sanitized surface that looks revitalized. The result is thorough cleaning that kills spores and organisms at their root, preventing regrowth for months longer than conventional residential pressure washing methods.

Protecting Your Landscaping

We take special care to protect the plants and landscaping around your home during the soft wash process. Before applying any cleaning solutions, we pre-wet all vegetation, bushes, flowers, and grass surrounding your home's foundation. This saturation creates a protective barrier that prevents cleaning solutions from being absorbed by plant roots. For particularly delicate plants or areas with dense landscaping directly adjacent to your home, we use protective coverings to shield vegetation during application. After completing the soft wash and final rinse, we perform a thorough post-rinse of all landscaping to ensure no cleaning solution residue remains. Our careful attention to your landscaping means you get a beautifully clean home without any damage to your garden, shrubs, or lawn.

This professional approach to plant protection is one of the key differences between our expert soft wash residential pressure washing service and DIY attempts, where homeowners often inadvertently damage expensive landscaping by not taking proper precautions with cleaning solutions.

Pressure Washing Water Usage

One of the most common questions Portland homeowners ask about residential pressure washing is: “How much will this increase my water bill?” The answer might surprise you—professional pressure washing is incredibly water-efficient.

Pressure Washing Uses 80% Less Water Than Garden Hoses

Despite the name “pressure washing,” our professional equipment actually uses significantly less water than washing your home with a garden hose. Pressure washers use approximately 80% less water than traditional garden hoses because they deliver water at high pressure, requiring less volume to achieve superior cleaning results.

Actual Water Costs for Residential Pressure Washing

According to the Portland Water Bureau, water costs about $0.01 per 1.5 gallons. An average house wash uses around 240 gallons, which equals approximately $2.40 in water usage. For perspective, that’s less than the cost of a cup of coffee, yet it transforms your entire home’s exterior.

What We Need From your Property

For residential pressure washing services, we require access to a working outdoor spigot with a minimum 4 gallon per minute output. The good news: most standard residential spigots easily meet this requirement. We bring all equipment, hoses, and cleaning solutions—you simply provide water access.

Why Professional Equipment Matters

Our commercial-grade pressure washing equipment maximizes cleaning power while minimizing water waste. This efficiency means lower environmental impact, reduced water costs, and faster service completion all while delivering superior results compared to DIY methods that waste water without achieving professional-quality cleaning.
