Stucco Repair

Stucco is a hard and durable material that, when installed by an expert, is one of the toughest building materials on the market. That said, even the toughest exteriors will eventually require maintenance and repair.

  • Prevent further, more costly damage
  • Avoid cosmetic blemishes
  • Blends seamlessly with your existing stucco


Factors such as building shifts, poor installation, and extreme weather can cause stucco issues that need to be addressed before they become bigger problems.

If your home's stucco does get damaged, the good news is that a professional contractor can easily fix it.

If left untreated, water and moisture can enter the opening and damage the building, requiring a more expensive repair. Hairline cracks are normal, but If you see that a crack appears in your stucco of more than half of an inch, stucco repairs are needed and you should dial Del’s Exteriors immediately.


  1. Water Stains or Discolouration – Wet stucco after rain/snow is normal, but if the stucco doesn’t return to a normal colour, it could be a sign that moisture has found its way behind the surface of the home's siding. You may notice that some areas of the exterior appear darker than the rest of the material, which could be evidence of a serious mold problem. 
  2. Cracks or Missing Pieces – Stucco is naturally prone to developing small cracks as it gets older. While small hairline gaps aren’t too worrisome, you should still consider having them repaired before they grow larger. Pay particular attention to deep crevices, as these can indicate structural damage. Spiderweb cracking is also an issue and generally the result of incorrect installation. If these blemishes are left untouched, water can seep inside, leading to significant damage that may require costly repairs.
  3. Bubbles or Blisters — Resulting from poor drainage, water leaking through stucco walls shows up along the bottom edge. If you see odd bubbles, you’re looking at the signs of stucco damage.

4. Window gapping or cracking – It's quite obvious when caulking around windows begin to gap. When this happens, moistures will be able to lead into your home, resulting in wall stains and flooring damage

5. Mold – A musty odor inside your home also typically accompanies this type of fungal issue. Surface mold can be easily cleaned, but it’s very important to determine the source to ensure the mold doesn’t spread, or return with a vengeance.

6. Moisture in the Basement – Take a look at your basement walls. Have you noticed stains on the walls or water pooling on the floor? If so, this is a clear sign that you likely have stucco problems that need to be addressed. Many people make the mistake of assuming that water in the basement is only caused by leaking pipe  and yet this problem could be directly related to stucco leaks on the exterior of your home. 

7. Damage from Animals – If you live in an area with a high wildlife population, you may find unwelcome guests using your home as a nest or storage area. The repairs may be as easy as removing the affected area and redoing the stucco, though are still important to take care of.

8. Insect Infestation – The presence of termites, ants, and other insects in your home is a sign of stucco damage; it’s likely the cracks in your stucco walls are their point of entry. 

9. Poor Installation – Cracks on the foam trim are clear signs that the stucco is not properly installed. When the seam is not properly connected, the stucco has chances of cracking and falling.
