House Washing 101: How to Keep Your Home Clean, Safe & Beautiful Year-Round
June 2, 2025
Seattle may be famous for its lush green beauty and rainy days—but all that damp weather also makes it easy for your home’s exterior to become dirty, streaked, and even moldy. If you’ve looked at your house lately and thought, “When did my siding get so dull?” — you’re not alone.
Then enters professional house washing. It’s not just about looks—it’s about protecting your home, your health, and your investment.
Whether you’re a homeowner in Tacoma, a property manager in Federal Way, or part of an HOA in Puyallup, this post will explain why house washing matters, how it’s done, and what makes Precision Pro Wash the right choice.
Seattle-Tacoma homeowners face unique environmental challenges:
- Heavy rainfall and moisture
- Moss, algae, and lichen growth
- Tree sap and pollen buildup
- Airborne pollutants and mildew
- Dust and dirt from nearby construction or traffic
These elements don’t just sit on the surface—they bond with your siding over time. Left untreated, this grime can lead to:
- Staining
- Faded paint
- Premature siding wear
- Mold growth that affects indoor air quality
- Reduced home value
A quick rinse with a garden hose won’t cut it. That’s where professional house washing comes in.
Soft Washing vs Pressure Washing: What’s Best for House Exteriors?
At Precision Pro Wash, we specialize in a technique called soft washing. Unlike high-pressure washing (which can damage delicate siding or push water behind surfaces), soft washing uses:
- Low-pressure water
- Eco-friendly cleaning solutions
- Specialized nozzles that gently clean without abrasion
This method is safe for:
- Vinyl siding
- Stucco
- Painted wood
- Hardie board
- Brick and stone
Soft washing doesn’t just clean—it sanitizes, kills algae, and slows future growth.

How Often Should You Wash Your House?
We recommend once a year for most homes, or every 6–9 months if:
- Your home is shaded and prone to moss
- You live near trees or wooded areas
- You’re close to the highway or an industrial zone
- You want to stay ahead of HOA requirements
While YouTube may make house washing look easy, using the wrong pressure, chemicals, or technique can:
- Strip paint
- Crack siding
- Void your warranty
- Force water behind your walls
