A quick description or photo helps.
Free, no obligation.
Itemized, no surprises.
Chip back, prep, coat, and clean up.
Researched, market-plausible ranges for the Ottawa market. Your exact number comes after a free on-site or photo estimate.
$300-$600
Small isolated area, spot chip-back and recoat, blended finish. Typical for a single crack or small spalled patch.
$600-$1,500
Multiple problem areas or one larger section, chip-back and recoat with a polymer-modified mix. The most common repair scope we see.
$1,500-$6,000
Widespread cracking or spalling, strip-and-replace where needed. Full perimeter recoat or new application runs $15-$30/linear ft, or $2,250-$4,500 on a typical 150 linear ft home.

Ottawa, ON. Failing parging chipped back to sound material, cracks addressed, and the wall recoated with a polymer-modified, freeze-thaw-rated mix. Drag the handle to compare.
Loose material comes off before we recoat – covering over a failing patch just hides the problem for a year.
We use polymer-modified, fibre-reinforced parging suited to Ottawa's freeze-thaw cycling, not a plain cement coat.
Itemized pricing before any work starts, so there are no surprises.
Parging Experts Ottawa repaired the cracked and flaking parging around our foundation. The new finish looks clean, even, and completely refreshed the exterior of our home.
We received a clear estimate and a straightforward explanation of the work. The crew completed our foundation parging neatly and left the property clean afterward.
Our older Ottawa home had several damaged areas along the foundation. The repairs blend in beautifully, and the finished surface looks much stronger and more polished.
We needed parging repairs after years of winter damage. The team responded quickly, repaired the problem areas, and delivered a smooth, professional finish.
Excellent attention to detail from beginning to end. Our foundation now has a consistent finish that looks great with the brick exterior. We are very pleased with the result.

Ottawa Parging Experts repairs, recoats, and installs foundation parging across Ottawa and the surrounding communities. We work on residential and commercial foundations in polymer-modified, fibre-reinforced parging rated for repeated freeze-thaw cycling, we chip back failing material before any new coat goes on, and we tell you plainly whether your wall needs a spot repair or a full recoat. The on-site or photo estimate is free and the written quote comes back within 24 hours.
Most parging calls come in after a hard winter, not during a new build. Ottawa regularly sees around 17 nights a year drop to -20°C or colder, almost all in January, and industry guides for this market put the annual freeze-thaw cycle count at 50 or more. Each cycle works water deeper into hairline cracks, then expands and contracts against the coating until chunks let go. The zone from roughly 12 to 18 inches above grade, where snow, road salt, and splash-back moisture concentrate, is the most common failure point on an Ottawa foundation.
Much of the Ottawa area sits on Leda clay, a sensitive marine clay left behind when the Champlain Sea covered the region roughly 12,000 years ago. As the clay's original salt content leached out over time, its structure weakened, which is part of why Ottawa-area foundations can crack and shift in ways a foundation on more stable soil elsewhere won't. That's a documented geological factor in this market, not just "old houses settle."
Parging alone doesn't fix foundation movement – it protects and finishes the coating over the concrete or block underneath. When a crack keeps reopening in the same spot after a repair, that's usually a sign the movement itself needs a look before we recoat again.
Parging needs above-freezing temperatures to bond and cure properly, which is why almost every job here runs between spring and fall – Ottawa's frost-free season runs about 158 days, roughly late April to early October. Book your inspection now and the repair itself, or a full perimeter recoat, gets scheduled into that window before the next freeze sets back in.

Parging is a thin cement or acrylic coating applied over the exposed concrete or block of a foundation. It protects the wall from moisture and gives the base of the house a clean, finished look.
Cement parging is traditional and hard-wearing. Acrylic parging flexes and resists cracking, which suits walls that move or stay damp – a real factor on Ottawa's clay-heavy soil. We recommend the right one on-site.
Roughly 10 to 25 years depending on surface prep, moisture exposure, and freeze-thaw cycling. Most early failures trace back to poor prep or water sitting against the wall.

Parging needs above-freezing temperatures to cure properly, so we schedule it from spring through fall. Winter months are for quotes and planning.
On August 31, 2026, national news and finance outlets carried the announcement covering how Ottawa Parging Experts builds foundation coatings for a city on Leda clay and 50-plus freeze-thaw cycles a year.
Reported the preparation standard – all loose, flaking and crumbling material chipped back to sound concrete or block before any new coat, the step that decides whether a repair lasts one winter or ten.
Covered the polymer-modified, fibre-reinforced mix used on every job – the polymer lets the cured coat flex with substrate movement, the fibre holds the matrix through repeated freeze-thaw.
Detailed the free on-site inspection or photo estimate and the itemized written quote returned within 24 hours, with pricing confirmed before work begins.
