Woodpecker Stucco Damage Repair in Calgary
Woodpeckers, mostly Northern Flickers, can put dozens of holes in EIFS stucco in a single season, and every hole lets moisture into your walls. Wave Stucco repairs the damage properly, rebuilding the insulation, mesh, and finish, then reinforces the wall with an impact-resistant coating so the birds move on. Every repair is colour- and texture-matched to your home. Full rebuild of damaged EIFS, not just filled holes.
Before And After
Every woodpecker repair is carefully rebuilt, reinforced, and blended to match the surrounding stucco. See how proper damage removal, texture matching, and colour blending can make the repaired area look clean and seamless.
Why Woodpeckers Damage Stucco
Most stucco damage in Calgary comes from the Northern Flicker, a large woodpecker found throughout Alberta's residential neighbourhoods. Flickers are drawn to EIFS (Exterior Insulation and Finish System) stucco because it's soft and sounds hollow.
Under a thin finish coat sits foam insulation that a bird can dig into easily, and tapping on it sounds like a dead tree full of insects.
Why Do Birds Peck at Stucco?
Drumming
In spring, flickers drum on loud, resonant surfaces to claim territory and attract a mate. A hollow-sounding wall is ideal.
Feeding
Birds may be chasing insects living in or behind the wall.
Nesting or Roosting
Some birds excavate a cavity in the foam to nest in or shelter from Calgary's cold weather.
A Small Hole Can Become a Bigger Problem
Whatever the reason, the result is the same. Each hole breaks your wall's waterproof finish. Water gets into the insulation, freezes and expands during Calgary's winters, and can eventually reach the sheathing and framing behind it.
When Woodpecker Damage Happens
Activity usually peaks in spring, from April to June, during drumming and nesting season.
There's often a second wave in late summer and fall, when birds look for sheltered spots to spend the winter.
Increased drumming, nesting and territorial activity.
Birds may search for sheltered areas as colder weather approaches.
Once a bird finds a wall it likes, it tends to return day after day. That's why fast action matters.
A single fresh hole is a quick repair; a whole season of damage is not.
Woodpeckers Are Protected by Law
Northern Flickers and other woodpeckers are protected under Canada's Migratory Birds Convention Act.
It's illegal to harm, trap, or kill them, and active nests can't be disturbed.
That's why our approach focuses on repairing the wall and making it unappealing to the bird, never on removing the bird itself.
If you think a bird is nesting inside your wall, call us before doing anything.
We'll help you plan the repair timing so it stays within the law.
Our Woodpecker Damage Repair Process
We repair the damage properly from the inside out, restore the EIFS system, and blend the finished repair into your existing stucco.
Free On-Site Inspection
We check every hole, tap-test the surrounding stucco for hidden damage, and look for signs of moisture behind the finish. You'll get a clear written quote before any work begins.
Remove the Damaged Material
Broken or wet foam is cut back to solid, dry material. Simply filling holes over damaged insulation traps moisture and leads to bigger problems later.
Rebuild the Insulation
We fit new EIFS-grade insulation board flush with the existing wall so the repair sits level and doesn't show through the finish.
Mesh and Base Coat
Reinforcing mesh is embedded in a fresh base coat and overlapped onto the surrounding sound stucco, so the patch bonds into the wall instead of sitting on top of it.
Impact-Resistant Reinforcement
We apply [product name / system], an impact-resistant coating that makes the wall harder for birds to penetrate and changes the hollow sound that attracted them in the first place.
Colour and Texture Matching
We match your existing finish texture and colour so the repair blends in with the rest of your home.
Final Walkthrough
We review the finished work with you, explain your warranty, and share tips for keeping birds away.
Most single-wall repairs take [1–2] days on site, plus curing time between coats. Stucco needs temperatures above 5 °C to cure properly, so we schedule around Calgary's weather.
How to Keep Woodpeckers Away
Repairing the wall is the most important step, but a few simple deterrents help keep birds from coming back.
Reflective Deterrents
Hang reflective tape, mirrored strips, or old CDs near the area where the bird was active. Movement and flashes of light make the spot feel unsafe.
Predator Decoys
Owl or hawk decoys can help, but move them every few days so birds don't get used to them.
Netting
Lightweight bird netting, angled away from the wall, can protect a problem area during peak season.
Deal With Insects
If the bird was feeding, an insect problem in or near the wall may be the real cause. We'll point out any signs during our inspection.
Act Fast
Repair new holes as soon as they appear. The sooner you act, the less likely the bird is to make your wall a regular stop.
How Much Does Woodpecker Stucco Repair Cost?
Cost depends on the extent and location of the damage. Every repair is different, which is why an inspection or clear photos give us the best way to quote accurately.

Frequently Asked Questions
Common questions about woodpecker stucco damage, repairs, prevention, timelines, and service areas.
Look for round holes, usually 2–5 cm across, often clustered near corners, eaves, or the top of walls. You may also hear loud tapping early in the morning, especially in spring.
Caulk, spray foam, or patching compound might cover the hole, but they don't restore the waterproof finish. They can also trap moisture behind the patch, and they leave the wall just as appealing to birds. A proper repair rebuilds the insulation, mesh, and finish layers.
Yes. We match both colour and texture. On older or faded stucco, we may suggest refreshing the full wall for the most even look.
Birds often return to spots they've used before. That's why we reinforce the wall rather than just filling holes, and why we recommend deterrents during peak season. [If applicable: Repeat bird damage on a treated wall is covered under our warranty.]
Many policies exclude damage caused by birds, insects, or animals, but coverage varies. Check with your insurer. We're happy to provide photos and a written estimate for a claim.
Most single-wall repairs take [1–2] days on site. Larger jobs or full-wall coatings take longer, and weather can affect curing time.
Stucco needs temperatures above 5 °C to cure properly. In cold weather, we can use temporary protection to stop water getting in and complete the full repair once temperatures allow.
Yes. We work with homeowners, property managers, and condo boards across Calgary, including upper-storey and balcony repairs.
