At William Richmond, we don’t offer power washing services, but we do recommend that home owners do it! A clean exterior boosts curb appeal, protects your investment, and can help extend the life of your home's siding - but using the wrong cleaning methods can actually cause damage.


Summer is one of the most popular times for homeowners to freshen up their home's exterior. Unfortunately, many people unknowingly damage their siding while trying to make it look better.

Most homes should have their siding cleaned every 1 to 2 years, depending on factors such as:


  • Tree coverage
  • Moisture levels
  • Shade exposure
  • Nearby landscaping
  • Local weather conditions


Homes with significant shade or moisture often develop algae, mildew, and mold more quickly and may require more frequent cleaning. Regular cleaning not only improves appearance but can also help prevent long-term staining and deterioration.

Many homeowners assume more pressure equals better cleaning. In reality, excessive pressure is one of the most common causes of siding damage.


High-pressure washing can:

  • Crack vinyl siding
  • Force water behind siding panels
  • Damage trim and caulking
  • Remove protective finishes
  • Create openings for future moisture intrusion


In some cases, the damage isn't visible immediately and may not appear until moisture problems develop later. For most siding materials, a soft-wash approach using proper cleaning solutions and lower water pressure is often the safest option.


When in doubt, consult a professional before attempting to clean your home's exterior.

If you've noticed green discoloration, black streaks, or mildew on your siding, you're not alone.


These issues are especially common on:

  • North-facing walls
  • Shaded areas
  • Homes surrounded by trees
  • Areas with high humidity


To help prevent future growth:

✓ Keep gutters clean and functioning properly

✓ Trim vegetation away from the home

✓ Improve drainage around the foundation

✓ Remove leaves and debris that trap moisture

✓ Schedule periodic exterior cleanings


Addressing these conditions early can help preserve both the appearance and longevity of your siding.

Sometimes siding problems aren't simply dirt or mildew.


Watch for these warning signs:

  • Cracked or broken panels
  • Warping or buckling
  • Loose sections
  • Faded color that won't improve with cleaning
  • Rotting trim boards
  • Water stains inside the home
  • Rising energy bills caused by air infiltration


If you notice any of these issues, it may be time for repairs—or in some cases, replacement.
