How We Install and Repair Stucco Siding

Our process begins by preparing the surface and applying multiple protective layers, including a weather-resistant barrier and lath foundation. We then apply a cement-based stucco mixture in coats, allowing proper curing time for strength and stability. If you're in need of repairs, we assess the damage, identify any moisture intrusion, and match the texture and color of the existing finish. Our goal is to blend repairs seamlessly while preserving the structural integrity of your exterior.

Understanding Stucco Siding: Benefits and Best Uses

Stucco is a plaster-like material made from a blend of cement, sand, lime, and water. When applied professionally, it hardens into a durable shell that resists fire, pests, and temperature fluctuations. Its thick texture gives it a distinct aesthetic, often associated with Mediterranean, Southwestern, or Spanish-style architecture — but modern stucco finishes can also suit contemporary designs.

One of the major appeals of stucco siding is its longevity. With proper maintenance, stucco can last 50 years or more. It's breathable, allowing moisture to evaporate, which helps prevent interior mold and mildew. When combined with proper drainage and sealing, stucco performs well in moist climates like Renton’s — especially with a modern three-coat or synthetic system.

Stucco also offers impressive sound insulation, reducing street noise and helping to create a more peaceful home interior. Its natural thermal resistance provides modest energy efficiency, and newer acrylic or elastomeric finishes increase flexibility and crack resistance.

For homeowners looking for a visually textured, high-performance siding that stands the test of time, stucco is a smart option. It can be colored directly in the mix, meaning you don’t need to repaint it often. And because it can be shaped into various finishes — from smooth to rough — it offers great flexibility for creative architectural detail.
