Common House Washing Questions
How often should I have my house washed in Corvallis?
In Corvallis’s humid climate, we recommend annual house washing to prevent moss and algae damage. Properties near heavily wooded areas or north-facing walls may benefit from cleaning every 8-10 months due to increased moisture and shade.
Will house washing damage my siding or paint?
Absolutely not! We use soft washing techniques with pressure under 500 PSI (garden hose strength). This is completely safe for all siding types including vinyl, wood, fiber cement, stucco, and painted surfaces. High-pressure washing can cause damage, which is why we never use it on homes.
What’s the difference between pressure washing and house washing?
House washing uses low-pressure soft washing with specialized cleaning solutions to safely clean delicate surfaces. Pressure washing uses high-pressure water (3000+ PSI) and is only suitable for concrete and other hard surfaces, never for house siding.
Do I need to be home during the service?
No, you don’t need to be home. Just ensure all windows are closed, pets are inside, and we have access to water and electricity. We’ll send before and after photos and can collect payment online or by mail.
Are your cleaning solutions safe for plants and pets?
Yes! We use EPA-approved biodegradable solutions that are safe when properly diluted and applied. We pre-wet all vegetation and use protective barriers. The solutions break down into salt and water within hours.
How long does house washing take?
Most single-story homes take 2-3 hours, while two-story homes require 3-4 hours. This includes setup, cleaning, and final inspection. Weather conditions may affect timing slightly.
What areas of my house do you clean?
Our comprehensive service includes all siding, trim, fascia, soffits, exterior window frames, shutters, doors, architectural features, and exterior gutters. We also clean outdoor light fixtures, mailboxes, and address plaques at no extra charge.
Why is Oregon moss so hard to remove?
Oregon’s climate creates perfect conditions for moss growth – constant moisture, mild temperatures, and high humidity. Moss develops deep root systems (rhizoids) that penetrate surfaces. Our soft wash solution kills moss at the root, preventing regrowth for 12-18 months, unlike pressure washing which only removes surface growth.
Serving All Corvallis Neighborhoods
From the historic Craftsman homes of College Hill to the modern developments in South Corvallis, we understand each neighborhood’s unique house washing needs. The tree-lined streets of Timberhill create extra moss challenges, while homes near the Willamette River face increased humidity and faster algae growth.
Properties in Northwest Hills often require more frequent cleaning due to elevation and exposure to coastal moisture, while Oak Creek residents deal with heavy shade from surrounding forests. We’ve cleaned hundreds of homes near Oregon State University, helping landlords maintain property values and homeowners protect their investments.
Why Corvallis Homes Need Special Care
Corvallis receives over 51 inches of rain annually, creating ideal conditions for moss, algae, and mildew growth. Unlike drier areas of Oregon, our homes face constant moisture from October through May. This extended wet season means organic growth isn’t just unsightly – it actively damages siding, holds moisture against wood, and can void manufacturer warranties if left untreated.
The OSU Extension Service notes that Willamette Valley homes experience 3x faster moss growth than Eastern Oregon properties. That’s why our house washing service includes specialized moss prevention treatments that create a protective barrier lasting 12-18 months – far longer than standard cleaning alone.
