Common parging problems we fix
Hairline cracking
From settling and frost movement through Toronto's freeze-thaw cycles.
Flaking or peeling
Where the old coat lost its bond and started lifting away from the wall.
Spalling
Chunks broken away, leaving pits and exposed concrete underneath.
Why parging fails faster in Toronto
Interlock Experts Toronto gets most of our parging calls after a hard winter, not during a new build. Ontario's freeze-thaw cycling works water into hairline cracks in the coating, then expands and contracts against the foundation until chunks let go. Clay-heavy soil across much of the city holds moisture against the wall longer than sandier ground does, which is why the same foundation can need a recoat years before a comparable one on better-draining soil.
Cement or acrylic – what we actually recommend
Most foundations are fine with a traditional cement parge coat. Where a wall visibly moves, sits in a damp low spot, or has failed more than once in the same section, we'll usually recommend a flexible acrylic parging instead, since it resists the cracking that keeps bringing you back to the same repair. We confirm which one makes sense once we've seen the wall, not before.
Parging FAQs
What is parging?
Parging is a thin cement or acrylic coating applied over the exposed concrete of a foundation. It protects the wall from moisture and gives the base of the house a clean, finished look.
Cement or acrylic parging – which is better?
Cement parging is traditional and hard-wearing. Acrylic parging flexes and resists cracking, which suits walls that move or stay damp – common in Toronto's clay-heavy soil. We recommend the right one on-site.
How long does parging last?
Cement parging typically lasts 10 to 20 years. Lifespan depends on surface prep, moisture, and freeze-thaw exposure – most early failures come from poor prep or water sitting against the wall.
Can you repair parging instead of redoing the whole wall?
Yes. When the rest of the coating is sound, we chip back and patch the failed areas and blend the finish. A full recoat is only needed when most of the old parging has failed.
Do you parge in winter?
Parging needs above-freezing temperatures to cure properly, so we schedule it from spring through fall. Winter months are for quotes and planning.
