How to Repair Woodpecker Damage

Step 1: Inspect the Damage (Repair vs Replace)

Prior to filling holes, determine the depth of the damage.

You can usually repair if:

• The wood remains solid when probed
• The hole is shallow or clean-edged
• No moisture staining or softness is visible

You should replace siding or trim if:

• The wood feels soft or spongy
• Holes penetrate deeply or show cavity access
• There is visible rot, swelling, or cracking
• Damage has occurred repeatedly in the same board

Rule: If a screwdriver sinks in easily, replacement is safer than patching.

Step 2: Choose the Right Repair Method

Method 1: Patch Small Holes and Divots

Best for: Shallow pecks, cosmetic damage, minor holes

1. Clear out loose fibers and debris
2. Allow the surface to dry completely
3. Fill with two-part epoxy wood filler
4. Overfill slightly and sand flush after curing
5. Prime any bare wood
6. Paint or stain to match existing finish

Epoxy fillers outperform standard caulk or lightweight putties in exterior conditions.

Method 2: Plug Clean Round Woodpecker Holes

Best for: Cedar siding and trim with round holes

1. Clean the hole using a hole saw
2. Cut a matching wood plug if possible
3. Secure the plug with exterior epoxy or adhesive
4. Sand level once dry
5. Prime and then paint or stain

This method restores strength and blends better than surface fillers alone.

Method 3: Replace Damaged Boards or Sections

Best for: Large holes, repeated attacks, moisture damage

1. Remove the damaged board with care
2. Inspect sheathing or framing underneath
3. Address any moisture issues found
4. Install a matching replacement board
5. Seal, prime, and finish all surfaces

Step 3: Seal and Finish Correctly

• Prime all exposed wood before painting
• Pay attention to end grain sealing
• Use paintable exterior caulk only at seams
• Match existing paint to protect repairs

How to Prevent Woodpeckers From Returning

Fixing holes alone often leads to repeat damage, sometimes within days.

Install Bird Netting

• Use 3/4-inch mesh netting
• Keep at least 3 inches of space from siding
• Cover the entire affected wall section

If netting is too narrow, birds will move to the edge and continue pecking.

Use Physical Barriers Where Needed

• Hardware cloth
• Sheet metal or PVC panels
• Protective flashing on corners and fascia

Visual Deterrents

Reflective tape or streamers may help temporarily but are best used as a supplement.

When Insects Do Matter

Insect treatment is appropriate only when signs are present, such as:

• Carpenter ants
• Carpenter bees
• Termites

If insects are confirmed, address them in addition to repairing damage.
