How much should I budget for stucco maintenance over a ten-year period in Ottawa?

Ottawa's climate is among the hardest on stucco in Canada — the combination of extreme freeze-thaw cycling, heavy snow loads, road salt drift, and intense summer UV means you need a real maintenance budget, not just hope for the best. For a typical Ottawa home with 1,500–2,200 square feet of stucco surface, plan on spending $3,500 to $8,500 over ten years, depending on your stucco type and current condition.

Year-by-year maintenance breakdown

Annual inspection and minor repairs (every year): $200–$500/year

Each spring, after Ottawa's freeze-thaw season wraps up, inspect for hairline cracks, chipped edges around windows and doors, and any staining from ice damming. Catching small cracks early — before water infiltrates and causes delamination — is the single most cost-effective thing you can do. A handyman or stucco contractor can patch minor cracks for $200–$500 per visit.

Power washing (every 2–3 years): $300–$600 per session

Ottawa homes, especially those near busy roads or mature trees, accumulate dirt, algae, and road salt residue that can degrade the stucco surface. A gentle power wash (under 1,500 PSI — never use high pressure on stucco) every couple of years keeps the finish clean and lets you spot problems. Budget two to three washes over the decade.

Caulking and sealant replacement (every 3–5 years): $400–$1,200 per round

The joints where stucco meets windows, doors, soffits, and flashings are sealed with caulk that deteriorates in Ottawa's temperature extremes. Replacing deteriorated caulking prevents the most common source of water intrusion behind stucco. Plan on doing this twice over ten years.

Elastomeric re-coating or painting (year 8–12): $5,000–$12,000

If your stucco was painted or coated, the finish typically lasts 8–15 years in Ottawa's climate. An elastomeric re-coat around the 10-year mark is good planning. Integrally coloured stucco lasts longer without repainting but may need a fog coat to refresh the appearance.

Ten-year budget summary:

• Annual inspections/small patches: $2,000–$5,000- Power washing (3 sessions): $900–$1,800- Caulking replacement (2 rounds): $800–$2,400- Optional re-coat (if needed): $5,000–$12,000- Conservative total (no re-coat): $3,700–$9,200- With re-coat: $8,700–$21,200

The single biggest money-saver is not ignoring small cracks. A $50 hairline crack repair in May can prevent a $3,000 delamination repair the following spring after water freezes behind the surface. Set a calendar reminder for a spring walk-around every April — your future self will thank you.
