Why do woodpeckers keep coming back to the same spot?

Once a flicker finds a wall that sounds hollow it returns season after season, and a simple filler patch leaves the same hollow sound. Graphex is a hardened layer that removes the drum-like response and is too dense to drill through, so the wall stops being a target.

Is woodpecker damage to stucco just cosmetic?

No. Each hole breaches the weather barrier, letting water into the foam and down to the sheathing, which leads to rot and mould. Sealing it early keeps the repair small and inexpensive.

Will the woodpecker repair be visible?

We colour- and texture-match the finish to the surrounding wall, so on most homes the repaired area blends in. On older faded finishes we advise up front if a section may need re-coating for a seamless match.

Which areas of Calgary do you serve for woodpecker repair?

All four quadrants of Calgary and surrounding communities including Airdrie, Cochrane, Okotoks, Chestermere, Strathmore and Langdon.

Why They Pick Your Wall, And What It Costs

Calgary's mature, treed communities, Tuscany, Rocky Ridge, Scenic Acres, Varsity and the inner-city, are prime woodpecker territory. Northern Flickers are drawn to EIFS (synthetic stucco) because the foam board behind the acrylic finish sounds hollow, like a dead tree. They drum on it to mark territory in spring and drill into it to excavate nesting cavities.

1. The Hollow Invite

EIFS puts foam insulation behind a thin acrylic skin. To a flicker, that hollow sound means a nesting cavity worth opening up.

2. The Breach

Every hole goes through the waterproof layer. Water enters the foam, tracks down the wall, and saturates the sheathing behind it.

3. The Rot

Foam channels keep water out of sight. By the time staining shows indoors, the damage behind the finish is usually far worse.

A Coat They Can't Peck Through

A patch fixes the hole. It does not change the wall the bird remembers. Flickers come back to the same elevation every spring, and a standard acrylic finish gives out at about 25 newtons, less than one hard strike.

Graphex is how we change the wall: a graphene-reinforced coating troweled on like a finish, tested at 75 newtons. The bird lands, taps, gets nothing, and moves on. We rebuild the damage first, coat after, and match your colour and texture. One crew, one job.

Don't Just Patch It. Coat The Whole Wall.

Patching a hole fixes today. Flickers come back to the same wall next spring. Full Graphex application is what actually ends it.

The repair

Holes cut out, rebuilt to the ADEX spec and texture-matched. The right call for a first-time strike caught early.

The problem elevation

Most damage happens on one or two walls, usually the quiet, sunny side of the house. We rebuild every hole, then coat that full elevation so there is nothing soft left to drum on. The most chosen fix.

Our Woodpecker Repair Process

A proper repair rebuilds the wall from the foam out, not a dab of filler in the hole.

Woodpecker damage cut back to a clean square opening in the EIFS, weather barrier intact behind

STEP 01

Cut it out

The cavity is cut back to sound material. No nest, no soft foam, nothing compromised stays in the wall.

STEP 02

New foam in

Fresh foam replaces everything we removed, cut to fit tight and flush. The insulation layer is whole again.

STEP 03

Mesh and base coat

Fibreglass mesh embedded in base coat ties the repair into the wall per the ADEX spec, the same reinforcement the rest of the system has.

Hardened protective coating applied over the completed woodpecker repair on a Calgary home

STEP 04

Graphex applied

Hardened Graphex goes over the repair, or the whole wall. Then we apply the finish after, matched to your colour and texture. 10-year warranty in writing.

WOODPECKER DAMAGE FAQ

What Calgary homeowners ask first.

Why do woodpeckers keep coming back? +

Once a flicker finds a wall that sounds hollow, it returns season after season, and a simple filler patch leaves the same hollow sound. Graphex removes the drum-like response and is too dense to drill, so the wall stops being a target.

Do I have EIFS or traditional stucco? +

Woodpeckers almost always target EIFS (synthetic stucco) because of the foam behind it; traditional cement stucco is solid and rarely pecked. If you're not sure which you have, we'll confirm on-site, the repair method differs, and getting it wrong traps moisture.

Is the damage just cosmetic? +

No. Each hole breaches the weather barrier, so water gets into the foam and down to the sheathing. Left alone it leads to rot and mould that's far more expensive to fix than the original holes.

Will the repair be visible? +

We colour- and texture-match the finish to the surrounding wall. On most homes the repair blends in; on older, faded finishes we'll tell you up front if a section may need re-coating for a seamless match.

Which areas of Calgary do you serve? +

All four quadrants of Calgary plus Airdrie, Cochrane, Okotoks, Chestermere, Strathmore and Langdon. Woodpecker calls cluster in the treed NW and inner-city, but we repair across the whole city.
