Stucco Cracking in Las Vegas Homes: What’s Normal and When to Worry

If you own a home in Las Vegas, chances are the exterior is finished with stucco. With hundreds of thousands of stucco-clad homes across the valley, stucco cracking is one of the most common topics that comes up during home inspections.

The good news? Not all stucco cracks are a big deal — but understanding which ones matter is key.

What Is Stucco?

Stucco is an exterior wall finish made from a mixture of:

• Cement

• Sand

• Lime

• Water

It is applied wet over exterior wall materials and then hardens into a durable, protective shell. Stucco can be:

• Sprayed or troweled on

• Finished with various textures

• Applied in multiple layers

Because of its durability and heat resistance, stucco is extremely popular in Las Vegas construction.

How Long Does Stucco Last?

When properly maintained, stucco can last 50–80 years.

In Las Vegas, regular maintenance is essential due to:

• Extreme summer heat

• Intense sun exposure

• Seasonal temperature swings

To maximize the life of stucco, homeowners should:

• Repair small cracks as they appear

• Repaint stucco surfaces approximately every 5 years

• Keep moisture from entering behind the stucco surface

Why Does Stucco Crack?

Stucco cracking is typical and can occur for many reasons, including:

• Natural settling of the home

• Seasonal expansion and shrinkage

• Poor workmanship or improper mixing

• Seismic movement

• Shrinkage during curing

• Structural movement over time

Because stucco is a rigid material applied over framing, some cracking is expected, especially in older Las Vegas homes.

Are Stucco Cracks a Big Deal?

In most cases, small stucco cracks are normal and not an immediate concern.

However:

• Small cracks should be repaired promptly

• Ignoring cracks allows moisture intrusion

• Moisture behind stucco can lead to bigger problems over time

Routine maintenance prevents minor cosmetic issues from becoming costly repairs.

How Are Stucco Cracks Repaired?

When caught early, stucco cracks are typically:

• Easy to repair

• Inexpensive

• DIY-friendly for small cracks

Many local hardware stores carry:

• Stucco patch compounds

• Elastomeric fillers

• Exterior paint products designed for stucco

Proper patching and sealing help prevent further cracking and moisture intrusion.

How Big Is Too Big?

Size matters when evaluating stucco cracks.

General guidelines:

• Hairline cracks (~1/16 inch)→ Common and typically minor

• Cracks around 1/8 inch wide (or large enough to fit a nickel)→ Time to consult a qualified professional

Larger cracks may indicate:

• Structural movement

• Improper installation

• Moisture-related issues
