Let’s be honest: soft washing your home probably isn’t at the top of your weekend to-do list. It’s easy to think, “My house looks fine,” or “I’ll get to it eventually.” But what actually happens if you just… never do it?
Spoiler: it’s not pretty. And it’s definitely not cheap.
Year 1–2: The Slow Creep Begins
At first, you might not notice much. A few dark spots on the north side of your house. Some discoloration near the gutters. Maybe a faint green tint where the roof meets the trees.
What’s really happening: Algae spores are landing on your siding and roof. In Greenwich’s humid, coastal climate, they find the perfect home. They start to colonize, feed, and multiply — often in shaded areas where moisture lingers.
The damage: Minimal, but the clock is ticking.
Year 3–5: It’s Not Just Dirt Anymore
Now the signs are harder to ignore. Black streaks run down your roof. Your white siding looks gray-green. The paint on your trim starts looking dull and chalky.
What’s really happening:
- Algae (Gloeocapsa magma) is actively feeding on the limestone in your shingles, breaking down their protective layer.
- Mold and mildew are holding moisture against your siding, creating the perfect conditions for rot.
- Dirt and pollution are bonding with organic growth, making surfaces harder to clean without professional help.
The damage: Your roof’s lifespan is shortening. Paint is deteriorating faster. Curb appeal is noticeably declining.
Year 5–10: The Expensive Consequences Arrive
By now, your home looks visibly neglected. Neighbors notice. Potential buyers would definitely notice. But the real problems are hidden.
What’s really happening:
- Roof granules are washing away, leaving shingles vulnerable to UV damage and leaks.
- Siding is warping or rotting in areas where moisture has been trapped for years.
- Paint is peeling and needs a full exterior repaint.
- Gutters are clogged with organic debris, causing overflow and foundation issues.
- Your home’s resale value has dropped — appraisers and inspectors will flag deferred maintenance.
The damage: You’re now looking at:
- Premature roof replacement: $10,000–$25,000+
- Siding repair or replacement: $8,000–$20,000+
- Full exterior repainting: $8,000–$15,000+
- Potential structural repairs from water damage: $5,000–$15,000+
All of this could have been prevented with annual soft washing at a fraction of the cost.
Year 10+: The Point of No Return
If a home goes a decade or more without proper exterior cleaning, the damage becomes deeply embedded. Even a professional soft wash can’t fully reverse years of neglect. You’re no longer maintaining — you’re repairing.
What’s really happening:
- Mold and mildew may have penetrated into walls and insulation.
- Wood rot may require structural rebuilding.
- Shingles may be so degraded that cleaning them causes further damage.
- The home’s market value has taken a permanent hit.
The damage: You’ve lost tens of thousands in preventable costs and home equity.
