If you’re planning a renovation or building a new home in Glendale, AZ, one big question may come up: Should you go with stucco or plaster for your walls? While these materials look similar, they have different strengths and ideal uses—especially in Arizona’s desert climate.

Let’s break down the differences between stucco and plaster, and help you decide which is better for your Glendale home.

What’s the Difference Between Stucco and Plaster?

Both stucco and plaster are cement-like materials applied to walls, but they differ in composition and purpose:

Plaster

Use

Primarily exterior

Mostly interior

Cement-based

Gypsum or lime-based

Durability

Why Stucco Is a Great Choice for Glendale Exteriors

Glendale’s hot, dry summers and occasional monsoon rains make stucco a popular siding material. It’s:

  • Durable in extreme weather

  • Fire-resistant

  • Low-maintenance

  • Texturable in various finishes

It also offers natural insulation, helping reduce cooling costs in Arizona’s intense heat. That’s why it’s a go-to option for homes in places like Tolleson and Peoria too.

When to Use Plaster

Plaster, on the other hand, is perfect for interior walls and ceilings. It offers:

  • A smooth, polished look

  • Easy repair of cracks or dents

  • Noise insulation benefits

  • Moldable shapes for decorative finishes

If you’re restoring a vintage or adobe-style home in Glendale, plaster may be used inside while stucco protects the exterior.

Can You Mix the Two?

Yes! Many Glendale homes feature stucco exteriors and plaster interiors. Just be sure to match each material with the right environment:

  • Use stucco for outside walls, fences, and trim.

  • Use plaster for stylish interior walls and ceiling details.

Cost Comparison: Stucco vs. Plaster in Glendale

Costs can vary depending on square footage and complexity:

  • Stucco (exterior): $6–$9 per sq. ft. installed

  • Plaster (interior): $5–$8 per sq. ft. installed

Stucco is a bigger upfront investment but lasts longer outdoors, especially when sealed and maintained properly.
