Indicators That It’s Time To Replace Your Siding
Siding Replacement in Alton, IL
Visible Cracks, Warping, or Rot
Cracks, warping, or signs of wood rot indicate the siding’s structural integrity is compromised, exposing your home to moisture damage and pests, signaling it’s time for a replacement to protect your property.
Frequent Need for Repainting
If your siding requires constant repainting or touch-ups, it’s a sign that the material is deteriorating, and replacing it can save you time, money, and effort in ongoing maintenance.
High Energy Bills
Rising utility costs often point to poor insulation from compromised siding, which allows air leaks. Upgrading siding can improve energy efficiency and reduce your heating and cooling expenses.
Mold, Mildew, or Fungus Growth
Persistent mold or mildew patches indicate moisture intrusion and material breakdown, creating health hazards. Replacement helps eliminate these issues and prevents further structural damage.
Bubbling or Blistering
Bubbles or blisters on siding surfaces suggest internal moisture or heat damage, weakening the material and decreasing curb appeal, making replacement necessary to restore function and appearance.
