How to Fix Aluminum Siding Section Old Mounting Holes Left Behind in Beverly, Chicago

You removed an air conditioner, satellite dish, or security camera from your aluminum siding, and now there are visible holes where it was mounted. Old mounting holes in aluminum siding are unsightly, allow water and pests to enter, and can lead to corrosion around the hole edges — especially in Beverly, Chicago, where property appearance impacts values in this popular South Side neighborhood.

Mounting holes in aluminum siding create stress concentration points that can lead to cracks during thermal expansion and contraction. The holes also allow water intrusion during wind-driven rain, and the exposed aluminum around the holes is vulnerable to corrosion.

Quick Answer: How Do You Fix Mounting Holes in Aluminum Siding?

For small screw holes, use aluminum-compatible epoxy filler or self-adhesive aluminum patches. For larger holes, cut out the damaged section and install a replacement panel. Always seal from both sides and apply corrosion-inhibiting primer around the repair. For holes with corrosion, remove all corroded material before patching.

Why Mounting Holes Are a Problem

Water intrusion. Rain penetrates through holes, damaging sheathing behind the siding.

Corrosion. Exposed aluminum around holes corrodes, weakening the panel.

Crack initiation. Holes create stress points where cracks start during thermal movement.

Pest entry. Insects and small rodents enter through larger holes.

Can You Fix It Yourself?

Small hole repair is DIY-friendly. Large holes require professional attention:

DIY-friendly: Small screw holes filled with epoxy or patched with aluminum tape.

Professional recommended: Large holes requiring panel replacement. Corroded areas. Second-story work.

Step-by-Step Repair

Step 1: Clean the hole and remove any corrosion.

Step 2: Apply corrosion-inhibiting primer around the hole.

Step 3: Fill small holes with aluminum epoxy or apply aluminum patch.

Step 4: For large holes, replace the panel section.

Step 5: Seal from both sides and touch-up paint.

Chicago Considerations for Beverly

Beverly has many older homes with aluminum siding. Chicago’s lake-effect winds drive rain through mounting holes with significant force. Professional sealing ensures the weather barrier is fully restored.

When to Call a Professional

Call when holes are large, corrosion is present, panels need replacement, or the damage is on the second story.
