How long does a full stucco application take on a typical Ottawa home?

A full stucco application on a typical Ottawa home usually takes two to four weeks from prep to final coat, though the timeline depends heavily on house size, weather windows, and the number of coats being applied.

Breaking Down the Stucco Timeline

For an average 1,500 to 2,000 square foot Ottawa bungalow or two-storey, here's what the schedule generally looks like:

• Surface preparation (2–4 days): Cleaning, installing lath or mesh, applying weather-resistant barriers, and setting up scaffolding. On older Ottawa homes with existing siding or damaged sheathing, prep can stretch to a full week.
• Scratch coat (1 day application + 24–48 hours curing): The first coat bonds to the lath and creates the rough surface for the next layer. It needs to cure properly before moving on — rushing this step in Ottawa's variable humidity leads to cracking within the first winter.
• Brown coat (1 day application + 7 days curing): This levelling coat builds thickness and creates a uniform surface. The seven-day cure time is critical and can't be shortened, even during Ottawa's warm summer stretches.
• Finish coat (1–2 days): The decorative final layer where texture and colour come together. This coat is thinner and cures faster, but still needs at least 24 hours of dry weather after application.

In total, you're looking at roughly 12 to 18 working days for a standard three-coat application. Larger homes — particularly Ottawa's Centre Town heritage properties or Barrhaven two-storeys with complex trim details — can push past three weeks.

Ottawa's weather is the biggest wildcard. Stucco can't be applied below 5°C or in rain, which means the realistic working season runs from mid-May through mid-October. A project that starts in late September might need to pause for cold snaps and resume in spring. Most Ottawa stucco contractors budget for at least one or two lost days per job due to weather interruptions.

For budgeting purposes, a full three-coat stucco job on a typical Ottawa home runs between $12,000 and $22,000 depending on square footage, access difficulty, and finish texture chosen. Getting quotes early in the season — February or March — gives you the best chance of locking in your preferred contractor before the summer rush.
