Stucco Repair & Crack Sealing in Kelowna & the Central Okanagan

Cracks are the most common reason homeowners in Kelowna reach out to us. Most cracks start small and cosmetic, but stucco is a rigid material sitting on a wall that moves — slightly, but constantly — with temperature, moisture and settling. Left alone, a hairline crack becomes an entry point for water, and water behind stucco causes damage that's a lot more expensive to fix than the crack itself.

Why Stucco Cracks in the Okanagan

Kelowna's climate is part of the problem. Winter freeze-thaw cycling means water that gets into a tiny crack can freeze, expand, and widen that crack, then thaw and let more water in the next time it rains or snow melts. Summer heat causes the wall assembly to expand; winter cold causes it to contract. Add in normal home settling, and even a well-built stucco wall will eventually develop some cracking over the years.

Types of Cracks We See

Hairline cracks, often just in the finish coat, are usually cosmetic if caught early. Diagonal or stair-step cracks near window and door corners typically point to structural movement or stress concentration at those openings. Wide, deep cracks that go beyond the finish coat into the base coat usually mean water has already been getting behind the wall for some time. Map cracking, a networked pattern across a large area, often signals a more systemic issue with the original mix or application.

Our Repair Process

We start by looking at where the crack is, how it's oriented, and whether it lines up with a window, door, control joint or corner — all common stress points. Where warranted, we check moisture levels behind the surface before deciding on a repair method rather than just filling the visible gap. Repair typically involves routing out the crack, applying a flexible sealant or patch material appropriate to the crack type, and then matching the surrounding texture and color so the repair isn't an obvious patch.

Texture & Color Matching

One of the most common complaints homeowners have after a DIY or lower-quality stucco patch is that it never quite blends in. We take the time to match the existing texture pattern — whether that's a fine sand finish, a heavier dash, or a smoother trowel finish — and work with tinted finish coats to get color as close as reasonably possible to the surrounding wall.

When Repair Isn't Enough

Not every cracked wall can be fixed with sealant and a patch. If cracking is widespread, if we find soft or delaminated areas once we start investigating, or if moisture has already reached the sheathing, we'll tell you honestly that the right move is a larger repair or a full re-coat rather than a patch that won't hold.
