Stucco has long been admired for its beauty, durability, and low maintenance. But even the toughest stucco finish isn’t invincible — especially in Calgary, where extreme weather tests every building material.
When issues arise, it’s important to act quickly. Small problems left unchecked can turn into major, costly stucco repair before you know it. At Golden Trowel Stucco, we help homeowners spot problems early and protect their most significant investment: their home.
Here are the top five signs you need immediate stucco repair, along with a few extras to watch.
1. Cracks Are Growing (Especially Around Doors and Windows)
It’s normal to see tiny hairline cracks in stucco over time. What’s not normal?
- Cracks that widen visibly
- Cracks that branch out like spiderwebs
- Cracks forming around windows, doors, or other seams
Why it matters:
Windows and doors are structural weak points. Cracks in them allow water to sneak behind the stucco, leading to moisture damage, rotting wood frames, and even mould growth.
Real Calgary example:
After a major Chinook wind event, a Golden Trowel client noticed widening cracks around their patio door. Inspection revealed early water infiltration, and fast repairs prevented a full re-stuccoing job.
2. Staining or Discolouration on Stucco Walls
Stucco staining isn’t just a cosmetic issue. It’s often a warning sign of deeper moisture problems.
You might notice:
- Brown, yellow, or black streaks
- Green patches (algae or mildew)
- White powdery deposits (efflorescence)
Why it matters:
Moisture trapped behind stucco can cause hidden damage for months before becoming visible inside your home.
Quick tip:
If you see stains forming near rooflines, window edges, or foundation walls, don’t just repaint—get a professional inspection.
3. Soft, Bulging, or Warped Walls
Give your stucco a light tap or press with your hand. Solid stucco should feel hard and firm.
If it feels soft, hollow, or spongy — or if you notice bulging areas — moisture is likely trapped behind the surface.
Why it matters:
This means the bond between the stucco and the substrate is failing. Over time, entire sections can detach, leading to dangerous conditions and expensive reconstruction.
What we look for:
Golden Trowel Stucco checks for warping patterns, moisture meter readings, and signs of subsurface damage before recommending any repair work.
4. Chipping, Flaking, or Crumbling Stucco
When stucco starts to crumble under your fingertips, it clearly shows that the material has degraded.
Causes include:
- Water damage
- Poor original mixing or application
- Freeze-thaw stress from Calgary’s fluctuating temperatures
Why it matters:
Surface degradation leaves the underlying layers vulnerable to even more rapid deterioration. Plus, it makes your home look poorly maintained, hurting its resale value.
Quick action saves money:
Small localized patching today can save you from a full exterior restoration tomorrow.
5. Unexplained Spike in Energy Bills
Stucco does more than just look good — it acts as an insulating layer for your home. If that layer is compromised, you’ll feel it… right in your wallet.
Signs of trouble:
- Higher heating bills in winter
- Cooling struggles in summer
- Drafts you can’t explain
Why it matters:
Moisture infiltration, cracked insulation layers, or thermal bridging through damaged stucco can dramatically lower your home’s energy efficiency.
Common Causes of Stucco Damage in Calgary
Understanding why stucco fails can help you catch issues earlier. Some of the most common causes include:
- Freeze-Thaw Cycles: Calgary’s swings between warm days and freezing nights put enormous pressure on building materials.
- Hailstorms: Even small hail can chip and pit stucco surfaces.
- Poor Drainage: Clogged gutters or improper sloping around your home can lead to water pooling against walls.
- Improper Installation: Sadly, some homes built quickly during boom periods were not properly stuccoed, setting the stage for early failures.
Golden Trowel Tip:
Inspect your stucco in spring and fall — especially after major storms — to catch small problems early.
