Your siding is the first line of defense against Long Island’s coastal winds, salt air, and freeze-thaw cycles. While quality siding lasts decades, ignoring the signs of failure can lead to expensive structural damage.

1. Visible Warping, Cracking, or Buckling

Siding that pulls away from the house or appears wavy is no longer weather-tight. On Long Island, moisture trapped in these gaps freezes and expands during winter, turning minor cracks into major structural rot and mold hazards.

2. The “Repainting Treadmill”

If you are repainting your wood or fiber cement siding every 3–5 years, the material itself is likely compromised. Modern alternatives, like premium vinyl or factory-finished fiber cement, eliminate this maintenance cycle entirely.

3. Skyrocketing Energy Bills

Compromised siding creates air leaks, forcing your HVAC system to work overtime. Replacing old siding with modern materials and updated house wrap can reduce heating and cooling costs by 20% or more.

4. Mold, Mildew, or Interior Water Stains

Green or black fungal growth isn’t just an eyesore—it’s a health hazard. On the coast, high humidity makes siding vulnerable. If you see water stains on your interior walls, moisture has already breached your home’s envelope.

5. Your Siding is 20+ Years Old

Even if it looks “okay,” 20-year-old technology lacks the energy efficiency and wind resistance of today’s materials.

• Vinyl: 20–30 year lifespan.

• Wood: 20–40 years (if perfectly maintained).

• Fiber Cement: 30–50 years.
