Your Exterior Paint Is More Than Cosmetics
Exterior paint serves a dual purpose: aesthetic appeal and protection against moisture, UV rays, insects, and rot. When paint deteriorates, structural components become exposed to damage.
1. Peeling or Flaking Paint
Peeling indicates lost paint adhesion, typically starting in moisture-prone areas like windows, eaves, and north-facing walls.
2. Chalking
A powdery white residue on siding indicates chalking, occurring when UV exposure breaks down paint binders.
3. Fading or Discoloration
All exterior paint fades naturally over time. Dramatic color variation between different sides suggests film deterioration.
4. Cracking or Bubbling
Paint cracks create water pathways to the substrate. Bubbling indicates trapped moisture beneath the film.
5. Visible Wood Grain Through Paint
When wood grain texture shows through paint, the coating has thinned beyond protective capacity.
6. Mold or Mildew Growth
Dark spots or greenish growth signal mold or mildew presence. Pacific Northwest conditions require mildew-resistant coatings.
7. Caulking Gaps or Failed Sealant
Caulking around windows, doors, and trim joints deteriorates over time. Cracked or shrinking caulking allows water intrusion into wall cavities.
Why Ignoring These Signs Gets Expensive
Each warning sign represents a breach in the home's protective envelope. Moisture behind failing paint causes wood rot requiring carpentry repairs significantly more expensive than repainting.
