Cracked, flaking or hollow parging on the foundation wall, explained plainly: patch or recoat, what a sound job involves, and what Calgary firms publish for it.
Parging in Calgary is the cement coat over the exposed foundation wall, the strip of concrete between the ground and the stucco or siding. Homeowners searching for parging Calgary usually mean one of three things: hairline cracks, a patch that has flaked off, or a coat that has gone hollow across a whole side after years of freeze-thaw. Sandstone Stucco Co is an advertising service that puts you in touch with independent Calgary stucco contractors, who quote and contract directly with you.
This page covers how parging fails, when a patch is enough and when a full-perimeter recoat is the more sensible scope, what a sound job involves, and the prices Calgary firms publish. It stops where the parging stops: cracks that run through the foundation, damp basements and structural movement belong to a different trade. To be introduced to a contractor for a no-obligation quote, call (403) 555-0148.
A defined chip or crack is a patch; a coat that is hollow or cracked along a whole wall is a recoat. The contractor who sees the wall decides the scope and should explain the choice.
Loose and hollow parging is taken back to solid concrete and the surface cleaned before anything new goes on. Ask how the contractor checks for hollow areas.
Ask which bonding agent or surface preparation, and which parging product and mix, the contractor will use. A named product has a manufacturer data sheet you can read.
Stucco base-coat manufacturers set minimum temperatures of 4°C to 5°C and a cure period. Ask how the contractor will handle a cold or wet week.
Cement parging can be left as a plain grey coat or finished in acrylic. Matching a weathered wall is hard, and a contractor should say up front if a perfect match is not possible.
Get the walls covered, product, finish, GST and payment terms in writing from more than one contractor, and you can compare quotes like for like.
Parging is a thin cement coat on a concrete foundation wall, and it sits in the hardest spot on the house: at ground level, taking meltwater, snow and freeze-thaw. Martini Stone Masonry describes the cycle for Calgary stucco this way: water enters small cracks, freezes at -20°C and expands. Parging at the base of the wall sits in the same freeze-thaw zone.
Martini also says snow piled against stucco softens and crumbles the lowest 12 to 18 inches of the wall, the stretch just above the parging. Calgary Parging said in 2024 that over 30% of its residential repairs address water damage from incorrectly installed gutters, eaves or flashing (its own jobs, not a city survey). A downspout that empties at the foundation is worth checking before anyone recoats the wall.
Not every crack means the coat has failed. Imasco, a stucco manufacturer, says some cracking is inherent to portland cement and is not a reflection of product quality. A hairline crack is a reason to have a contractor look, not a reason to assume the worst.
A patch suits a defined area: a chip, a hairline crack or a palm-sized flake, with the rest of the coat sound when tapped. A recoat suits a coat that is hollow, crumbling or cracked along whole walls, because new material patched beside a failing coat has little sound surface to hold to.
Calgary Parging publishes these parging prices on its cost guide (reviewed May 2026, all before 5% GST). They are one firm's ranges, not a Calgary average, and a contractor's quote after seeing your wall is what counts.
The same firm says properly applied parging lasts 15 to 25 years and that most residential jobs wrap in 1 to 2 days. Those are the firm's own statements, not a promise from this site or the result of an independent test. For stucco figures on the wall above, see the stucco repair cost page.
A parging coat holds only as well as the surface under it. These are the points worth asking every contractor about, and they make a useful checklist when you compare written quotes.
Those data sheets are for stucco base coats. A parging product has its own, so ask the contractor for it. If you want the wall finished in acrylic, Calgary Parging lists that at an extra $575 to $1,035 over parging, before GST.
Parging is a surface coat. A crack that runs through the foundation wall, keeps widening, steps along the joints, or comes with damp inside the basement is a foundation or structural question. That is a different trade, and this page does not cover crack injection, waterproofing or structural repair. A foundation contractor or engineer is who to ask.
Sandstone Stucco Co is an advertisement paid for by contractors. It puts you in touch with an independent Calgary stucco contractor, who quotes and contracts directly with you. The site does no work and holds no licence, certificate, insurance or warranty.
Alberta.ca advises insisting on a written contract, getting written estimates from more than one business, and checking that the contractor has Workers' Compensation Board coverage. The City of Calgary says contractors need a valid City of Calgary business licence, which you can confirm by calling 311. For a prepaid contract over $200, Alberta's regulation requires the contract to set out the quality or types of materials and the work to be carried out.
Call (403) 555-0148 to be introduced to a contractor for a no-obligation quote. If the wall above the parging is damaged too, see stucco repair in Calgary and re-stucco.
Calgary Parging publishes $400 to $860 for small patch or chip repairs, $975 to $1,700 to recoat one side of a house and $2,350 to $4,000 to recoat the full perimeter, all before 5% GST (cost guide reviewed May 2026). Those are one firm's ranges, not a city average. The contractor sets the actual price after seeing the wall, so get it in writing and compare more than one.
A patch fits a defined area on an otherwise sound coat. Calgary Parging lists hairline crack repair at a $345 to $520 minimum charge and small patches at $400 to $860, before GST. If the coat sounds hollow or is cracking along whole walls, a contractor may scope a recoat, which the same firm prices at $975 to $1,700 for one side. Ask the contractor why they chose that scope.
Stucco base-coat manufacturers set minimums of 4°C (Imasco) or 5°C (ADEX) for at least 24 hours, and Imasco calls for moist curing for a minimum of 48 hours. Calgary Parging says stucco cures best above 5°C, typically April through October, and that off-season work needs heated hoarding. Ask any contractor quoting winter work which product and cure plan they will follow.
Calgary Parging lists parging with an acrylic stucco finish at $3,100 to $4,850, and acrylic over parging as an addition of $575 to $1,035, both before GST. Martini Stone Masonry says acrylic stays flexible through freeze-thaw and resists hairline cracking better than cement finish. That is the firm's claim, not an independent test.
Not automatically. A hairline crack in the parging coat is the job Calgary Parging prices at a $345 to $520 minimum charge, before GST. A crack through the foundation itself, or damp inside the basement, is a foundation or structural matter, a different trade that this site does not cover. A coat of parging is not the tool for it, so ask a foundation contractor or engineer.
