How much does it cost to repair stucco damage caused by woodpeckers in Ottawa?

Woodpecker damage is one of those Ottawa stucco problems that looks alarming but is usually very fixable — as long as you address it before moisture gets behind the wall assembly. Here in Ottawa, we see this most often on homes backing onto the Greenbelt, near the Rideau River corridor, and in mature neighbourhoods like Alta Vista or Westboro where large trees attract these persistent birds.

Typical Repair Costs for Woodpecker Damage

For a single hole or a small cluster of pecked-out areas, expect to pay between $250 and $600 for a professional patch repair. This includes removing the loose or crumbled stucco around the hole, inspecting the underlying lath and weather-resistant barrier (WRB) for moisture damage, applying a proper multi-coat patch, and colour-matching the finish.

If the woodpecker has been at it for a while and created multiple holes across a larger section — say 20 to 50 square feet — the cost rises to $800 to $1,800. At that point, your contractor may recommend cutting out the entire damaged section and re-stuccoing it rather than doing individual patches, which gives a much cleaner result.

Where costs escalate is when the holes have allowed water infiltration. If the WRB or building paper behind the stucco is punctured, or if the sheathing shows signs of rot or mould, remediation can push the total to $2,000 to $4,000+ depending on how far the moisture has travelled. Ottawa's freeze-thaw cycles — we typically see 40 to 50 crossings per winter — mean that even a small amount of moisture behind stucco can cause significant damage quickly as ice expands in the wall cavity.

A few things to keep in mind:

• Colour matching is the trickiest part of any stucco patch. Aged stucco fades, and even a perfect product match may look slightly different. A skilled applicator can feather the repair to minimize visibility, but a perfect blend on older homes is rare without recoating the entire wall face.- Deterrent installation — reflective tape, bird netting, or hardware cloth over vulnerable spots — adds $100 to $300 but can save you from repeat repairs. Woodpeckers often return to the same spot.- Insurance typically does not cover woodpecker damage, as it's classified as pest damage rather than sudden or accidental loss. Worth checking your policy, but plan to pay out of pocket.

For the repair itself, make sure your contractor uses a bonding agent on the existing stucco edges and applies the patch in proper layers — scratch coat, brown coat, finish coat — rather than filling the hole in one thick application. A single-fill patch will crack and fall out within a season or two, especially with Ottawa's temperature swings from -30°C winters to +35°C summers.

Get the repair done before late fall. You want at least 7 to 10 days of above-5°C temperatures for proper curing, and once November hits in Ottawa, that window closes fast.
