Stucco Repair Calgary, Expert Exterior Stucco Contractors
Martini Stone Masonry has repaired stucco on more than 500 Calgary-area homes since 2006, from hairline surface cracks to complete EIFS failures. Calgary's climate creates the damage (-30°C freeze-thaw winters, July to August hailstorms and snow sitting against the bottom courses), and every repair method the company uses is selected for exactly those conditions.

CALGARY CONDITIONS
Common Stucco Problems in Calgary's Climate
Calgary's temperature swings create specific stucco failures that our repair crews encounter weekly, from Rocky Ridge to Seton:
- Freeze-thaw cracking: water penetrates small cracks, freezes at -20°C and expands, spreading spider-web patterns across the wall.
- Hail impact damage: golf-ball-sized hail (most common in July and August) leaves 2-5 mm indentations that break the moisture barrier even when the wall looks intact from the street.
- Bottom-edge deterioration: snow piled against stucco softens and crumbles the lowest 12-18 inches of the wall.
- Window and door separation: temperature movement opens 3-8 mm gaps where stucco meets frames.
- Woodpecker holes: a persistent EIFS problem, since woodpeckers are a protected species and return to the same soft spots.
Each failure needs a different repair approach. Left open, all of them feed water into the sheathing, insulation and framing behind the stucco.
REPAIR SYSTEMS
Types of Stucco Repair We Complete in Calgary
The home's system (conventional three-coat, IMASCO or EIFS) determines the repair method.
Conventional Stucco Repairs
Traditional three-coat stucco (roughly 65% of Calgary homes built before 2000) takes portland cement-based repairs. Martini Stone Masonry matches existing textures using IMASCO Minerals products, so patches blend instead of telegraphing through the finish. If you are refinishing rather than patching, choosing stucco colours and textures covers the options.
EIFS Repairs
EIFS needs synthetic materials and dedicated technique. For woodpecker-prone walls the company uses ADEX Graphex, a graphite-enhanced finish that withstood 25,000 consecutive simulated strikes at 20 N (maximum bird force) with zero damage, and the only coating in our experience that stops birds returning to the same spots. The same impact resistance makes Graphex the strongest hail-proof stucco finish available here; hail-proof exterior planning is covered on the Exterior Renovations page.
Crack Sealing and Flexible Repairs
For cracks that move seasonally, rigid fillers re-crack after the first winter. The company uses elastomeric products, Sika Flexible Crack Filler and Mor-Flexx, formulated to stay flexible through freeze-thaw cycles, and DAP All-Purpose Stucco Patch for colour-blendable surface patches on conventional stucco.
Emergency Water Damage Repairs
When spring melt reveals open cracks or interior water stains appear, the emergency crew responds within 24 hours: active leaks are sealed temporarily, and comprehensive repairs are scheduled once weather permits.
HAIL & INSURANCE
Hail Damage Stucco Repair and Insurance Claims
Calgary's 2020 hailstorm generated $1.2 billion in insured claims, and stucco damage featured in a large share of them. Most home policies cover sudden hail damage (while excluding gradual deterioration), so documentation decides the claim. Martini Stone Masonry photographs and maps hail damage during the free assessment, provides the written documentation insurers ask for, and completes the repair once the claim is approved.
Rebuilding after hail is also the right moment to upgrade exposed elevations to hail-proof finishes. See hail-proof exterior upgrades for how stone, brick and impact-rated stucco compare.
CHOOSING A CONTRACTOR
How to Choose a Stucco Repair Contractor in Calgary
Choosing the wrong contractor costs Calgary homeowners an average of $8,500 in redo work (BBB Alberta complaint data, 2023). Verify these five credentials before signing:
- Alberta-specific licensing: City of Calgary business licence and WCB coverage (Martini Stone Masonry: WCB Account #8180853).
- Manufacturer certification: only certified applicators can pass material warranties through to you.
- Local project portfolio: ask for addresses of completed repairs in your neighbourhood for drive-by viewing.
- Written warranty terms: legitimate contractors offer 5-10 year workmanship warranties in writing.
- Insurance documentation: minimum $2 million liability coverage.
Red flags: cash-only demands, "limited-time pricing" pressure, and reluctance to provide local references.
Martini Stone Masonry meets each of these, and the repairs themselves are completed by its own in-house crews. Texture matching in particular depends on it: the patch and the wall around it read as one surface when the same hands finish both.
PROCESS
Stucco Repair Process: What to Expect
Day 1-2: Assessment and Preparation
Technicians perform moisture testing at 15-20 points around the home, map the damage, photograph existing conditions and establish the repair scope. You receive a detailed quote within 48 hours.
Day 3-5: Active Repair Work
Damaged sections are removed down to sound substrate. Conventional stucco gets scratch, brown and finish coats with 24-hour curing between layers; EIFS repairs replace damaged foam board, embed mesh in a new base coat and finish with Graphex.
Day 6-7: Texture Matching and Cleanup
New sections are blended into the existing texture, the step that separates a repair you can find from one you can't. Drop cloths and daily cleanup protect the property throughout.

COMMON QUESTIONS
Commonly Asked Questions About Stucco Repair in Calgary
Answered by
Astrit Martinaj
Owner & Operator · 20+ years of masonry
How long does stucco repair take in Calgary?
Most residential repairs take 3-7 days depending on damage extent and weather. Minor crack repairs finish in 1-2 days; major wall sections need a full week. Spring and fall offer ideal curing conditions, and emergency repairs run year-round.
Can you repair stucco in winter?
Yes, with limits. Winter repairs proceed when temperatures hold above -5°C for 48 hours, using heated enclosures and IMASCO cold-weather additives. Emergency water-infiltration repairs proceed regardless of temperature.
What's the difference between patching and full restoration?
Patching fixes isolated damage (cracks, holes, small sections) for $500-$3,000. Full restoration strips all existing stucco, repairs the substrate and applies a new system, typically $25,000-$40,000 for an average Calgary home. We recommend patching when damage covers less than 15% of the wall area.
Does homeowner insurance cover stucco repair in Calgary?
Most policies cover sudden damage (hail strikes, vehicle impacts) and exclude gradual deterioration. We provide the photographic documentation and written assessment insurers require.
How do I know if my stucco has moisture damage?
Warning signs: interior wall discoloration, musty odours, soft or spongy areas under hand pressure, efflorescence (white powder) on the exterior, or visible mould. We measure with professional moisture meters; readings above 19% cross the structural-damage threshold.
What warranty comes with professional stucco repair?
Martini Stone Masonry provides a 5-year workmanship warranty on all repairs, plus manufacturer warranties on materials: 5 years on IMASCO products and 10 years on ADEX Graphex systems. See project warranty details.
