How often should stucco be repainted on an Ottawa home?

The repaint schedule for stucco in Ottawa depends heavily on what product was used last time, the orientation of your walls, and how well the surface was prepared. Ottawa's climate is among the harshest in Canada for exterior finishes — our 50–60°C annual temperature swing puts enormous stress on any coating.

Typical Repaint Timelines for Ottawa Stucco

Elastomeric coatings: 10–15 years between repaints. These thick, flexible coatings handle Ottawa's freeze-thaw cycles better than anything else. If your home was coated with a premium elastomeric product and properly prepared, you may push 15 years before needing a fresh coat.

100% acrylic latex paint: 7–10 years. This is the most common paint type on Ottawa stucco homes. South- and west-facing walls fade faster due to UV exposure, so you may notice colour differences between sides of the house by year 5–6.

Standard latex paint: 4–6 years. Lower-quality paints simply can't keep up with Ottawa's temperature extremes. If your stucco was painted with a budget product, you'll see chalking, fading, and hairline cracks much sooner.

Mineral/silicate paint: 15–20 years. These are the longest-lasting option, though they're less common in Ottawa. If you have heritage stucco with silicate paint, you likely won't need to repaint for a very long time.

Signs it's time to repaint: Run your hand along the stucco — if you get a chalky residue on your fingers, the binder is breaking down. Look for fading (especially on south-facing walls), hairline cracks in the paint film, peeling at edges or around trim, and any spots where bare stucco is showing through. After Ottawa ice storms, check for impact damage where ice has chipped the coating.

Orientation matters: South-facing walls take the most UV punishment and typically need repainting 2–3 years earlier than north-facing walls. North walls have the opposite problem — they stay damp longer and are more prone to mildew and algae staining, which may require cleaning even if the paint itself is still sound.

Cost planning: Professional stucco repainting in Ottawa runs $3.50–$6.00 per square foot, including washing, minor crack repair, priming, and two coats. For a typical 2,000 sq ft home with about 1,200–1,500 sq ft of stucco surface, that's $4,200–$9,000. Many homeowners find that investing in elastomeric paint ($1,000–$2,000 more than standard) pays for itself by pushing the repaint interval out by 5+ years.

A good rule of thumb: inspect your stucco every spring after the snow melts. Catching small issues early — a hairline crack here, a peeling edge there — lets you do spot touch-ups for $200–$500 instead of a full repaint.
