How Mold and Mildew Impact Your Home’s Exterior

Your home’s exterior should be a source of pride, not a breeding ground for mold and mildew. These unwelcome invaders don’t just look bad; they quietly eat away at siding, roofs, and other surfaces, lowering your property’s value and even affecting your family’s health.


Why Mold and Mildew Grow on Your Home

  • Moisture magnets: Shaded, damp areas like north-facing siding and roof valleys create the perfect conditions for mold and mildew to thrive.

  • Organic buildup: Dirt, pollen, and debris provide food sources that accelerate growth.

  • Neglected cleaning: Without routine maintenance, spores spread quickly across siding, decks, and walkways.

The Damage They Cause

  1. Exterior deterioration: Mold eats away at siding, paint, and roofing shingles, leading to costly repairs.

  2. Health hazards: Mold spores can trigger allergies, asthma, and respiratory issues, especially when they creep indoors.

  3. Curb appeal killer: Dark streaks and stains instantly drag down your home’s appearance and market value.

Why DIY Cleaning Isn’t Enough

Many homeowners try scrubbing or spraying with store-bought cleaners. The problem? Mold and mildew return fast if not removed properly. Harsh chemicals can also damage siding, landscaping, and paint.


Professional soft washing from Loyal Exterior Cleaning uses solutions that eliminate spores at the root, keeping surfaces clean longer.
