How to Spot Stucco Cracks and What to Do About Them

Stucco is a durable, long-lasting exterior choice that offers a beautiful finish to homes and businesses. However, over time, it can develop cracks due to weather changes, settling foundations, or improper installation. Spotting and addressing these cracks early is crucial to maintaining your stucco’s integrity and preventing more significant issues. Here's a guide on how to identify stucco cracks and the best steps to take to fix them.

Common Types of Stucco Cracks

1. Hairline Cracks
   These thin cracks (less than 1/16 inch wide) are often caused by minor settling or shrinkage as the stucco cures. They are usually cosmetic but can allow moisture in if left untreated.
2. Diagonal Cracks
   Found around windows, doors, or corners, diagonal cracks are often caused by shifting or settling in the foundation. These may indicate structural movement and should be inspected by a professional.
3. Map Cracks (Crazing)
   A pattern of tiny cracks resembling a spiderweb or road map. These often occur due to poor application or rapid drying during installation.
4. Vertical Cracks
   Vertical cracks running straight down the wall may indicate structural stress. They often form when the building's frame shifts or expands.
5. Corner Cracks
   Found where two walls meet or at the edges of windows and doors, these can be caused by poor bonding of the stucco in those areas.

How to Spot Stucco Cracks

1. Inspect Your Stucco Regularly
   Walk around your property and visually inspect the stucco at least twice a year. Pay special attention to areas near windows, doors, and corners.
2. Feel for Surface Changes
   Run your hand along the stucco to detect uneven surfaces or cracks that might not be visible from a distance.
3. Check After Extreme Weather
   Reno’s hot summers, cold winters, and occasional storms can cause stucco to expand and contract. After severe weather, take a close look for new cracks.
4. Use a Flashlight
   Shine a flashlight along the wall at an angle to reveal hairline cracks that might be hard to see in normal light.

What to Do About Stucco Cracks

1. Hairline Cracks
   These are often easy to repair. You can use a high-quality, paintable acrylic caulk to fill the crack, then touch it up with matching paint to blend with the existing stucco.
2. Larger Cracks
   For cracks wider than 1/16 inch, it's best to consult a professional. These may require a more in-depth repair using a patching compound and a stucco finish to match the texture.
3. Recurring or Structural Cracks
   If cracks keep reappearing or are associated with structural issues, you should call a contractor immediately. Ignoring these cracks could lead to water infiltration, mold, and even damage to your home’s foundation.
4. Resurfacing for Widespread Cracking
   If cracks are widespread across the stucco, resurfacing might be the best option. This involves applying a fresh layer of stucco or a specialized coating to restore the appearance and durability of the surface.

Why Addressing Stucco Cracks is Important

Ignoring stucco cracks, even small ones, can lead to:

• Water Damage: Moisture can seep through cracks, causing mold, mildew, and structural damage.
• Decreased Curb Appeal: Cracked stucco detracts from your property’s beauty and value.
• Expensive Repairs: Minor issues can escalate into significant, costly repairs if not addressed promptly.
