Stucco Repair

Stucco takes a real beating in the GTA climate. Freeze-thaw cycles, settling, and the occasional impact all lead to cracking and chipping over time, and small cracks are more than a cosmetic issue — they let water into the wall assembly, where it freezes, expands, and widens the damage each winter. Addressing stucco cracks early, especially before the cold season, prevents a minor repair from turning into a much larger one.

Our stucco repair process starts by removing loose or damaged material back to a sound substrate, then rebuilding with a scratch, brown, and finish coat system matched to your existing texture profile — fine, medium, or heavy dash. The finish coat is typically spray-applied for even, consistent texture, and we feather the edges of the repair so it blends into the surrounding wall rather than reading as an obvious patch. Once cured, the repaired area — or the full elevation, for a completely uniform look — is finished with a colour-matched, weatherproof masonry coating.

Sigma Painting repairs and repaints stucco across Pickering, Durham Region, and the GTA, and this work pairs naturally with a full exterior painting project when you want one consistent, refreshed look across the whole home. Like all exterior work, stucco repair is scheduled for the warmer months when temperatures and humidity allow the material to cure properly. Call us for an on-site assessment and a clear plan for stopping the damage before it spreads.
