How much does it cost to stucco a chimney in Ottawa?

Stuccoing a chimney in Ottawa typically runs between $800 and $2,500, depending on the chimney's height, accessibility, and current condition. A standard single-storey chimney that's easy to reach from the roofline sits at the lower end, while a tall chimney on a two-storey home requiring extensive scaffolding pushes costs higher.

What Drives Chimney Stucco Costs in Ottawa

The biggest variable is access. If your contractor can work safely from a roof ladder or simple staging, labour stays reasonable at around $55–$75 per hour. But a chimney that rises well above the roofline on a steep pitch may need proper scaffolding, adding $400–$800 to the project. Most Ottawa stucco contractors factor scaffolding into the quote rather than billing it separately.

Material costs for a chimney are modest since the surface area is relatively small — usually 60 to 120 square feet. A three-coat traditional stucco application (scratch, brown, and finish) runs about $8–$12 per square foot for materials. If you're matching existing stucco on the rest of your home, your contractor will need to colour-match the finish coat, which may require a custom tint mix.

Ottawa's freeze-thaw cycles are particularly hard on chimney stucco. The chimney is the most exposed element of your home — it catches wind, rain, ice, and direct sun. A proper application here means using a high-quality acrylic-modified finish coat that flexes with temperature swings from –30°C winter nights to +35°C summer afternoons. Cheap, rigid mixes crack within a few seasons.

Before applying new stucco, the existing substrate matters. If the chimney brick is in good shape, a bonding agent and metal lath provide an excellent base. If the mortar joints are deteriorating, those need repointing first — add $200–$500 depending on severity. Any chimney cap or flashing work should be done before the stucco goes on, not after.

One cost consideration specific to Ottawa: if you're doing this work in the optimal season (May through October), you'll get better pricing and better results. Stucco needs consistent temperatures above 5°C for proper curing, and Ottawa's reliable warm stretch gives contractors a solid window. Scheduling outside peak summer months — late May or September — often saves 10–15% on labour.

For a typical Ottawa home with a standard-height chimney, budget around $1,200–$1,800 all-in as a realistic midpoint. Get at least three quotes and make sure each includes surface prep, lath, all three coats, and cleanup.
