What is Stucco, and What Homebuyers in Florida Need to Know

Stucco has long been a popular exterior finish for homes, particularly in Florida, where its durability, versatility, and aesthetic appeal complement the region's architectural style. We want to provide you with information and a better understanding of stucco, its maintenance, common issues, and what to watch for when considering a home with a stucco exterior.


What is Stucco?

Stucco is a type of exterior plaster made from a blend of cement, sand, lime, and water. Applied in multiple layers over a wire mesh or lath, stucco creates a hard, durable, and textured finish. It is prized for its ability to:

  • Withstand Florida’s humid climate when properly installed and maintained.

  • Provide excellent thermal insulation, keeping homes cooler in the summer.

  • Be molded into various textures and finishes to match different architectural styles.


Maintaining Stucco

Proper maintenance is key to extending the life of stucco and preserving its appearance. Here are some tips for maintaining stucco:

  1. Inspect Regularly: Check for cracks, stains, or areas of damage, especially after severe weather events.

  2. Clean Annually: Use a mild detergent and a soft-bristle brush or low-pressure washer to remove dirt, algae, and mildew.

  3. Seal When Necessary: Periodically applying a high-quality sealant can help protect stucco from moisture penetration.

  4. Address Cracks Promptly: Even small cracks can allow water intrusion, leading to more significant damage over time.


Common Problems Found with Stucco

Despite its durability, stucco can develop issues, especially when improperly installed or neglected. Some of the most common problems we encounter during home inspections include:

  1. Cracks: Small hairline cracks are common and may not pose immediate risks. However, larger cracks can allow water intrusion, leading to mold, mildew, or structural damage.

  2. Moisture Retention: Florida’s high humidity and heavy rains can cause water to seep behind stucco if not properly sealed or if drainage systems are inadequate.

  3. Delamination: This occurs when stucco separates from the underlying wall, often due to poor adhesion or moisture issues.

  4. Staining and Discoloration: These can result from algae growth, water intrusion, or efflorescence (salt deposits).

  5. Improper Installation: Poorly installed stucco, such as insufficient expansion joints or improper flashing, can lead to premature failure.


What to Look for When Buying a Home with Stucco

If you’re considering purchasing a home with a stucco exterior, there are a few key factors to evaluate:

  1. Look for Visible Damage: Walk around the home and check for cracks, bulges, or discoloration on the stucco surface.

  2. Check the Drainage System: Ensure the home has proper gutters, downspouts, and grading to direct water away from the stucco.

  3. Ask About Repairs and Maintenance History: Request information on any previous stucco repairs, maintenance, or inspections.

  4. Consider the Age of the Stucco: Older stucco may require more maintenance and might not meet current building standards.

  5. Hire a Professional Inspector: A comprehensive home inspection can identify underlying issues that aren’t visible to the untrained eye, such as moisture intrusion or improper installation.


Bottom Line

Stucco is a beautiful and durable exterior option, particularly suited to Florida’s climate. However, it requires proper installation and regular maintenance to avoid costly issues. Whether you’re a homeowner or a prospective buyer, understanding the nuances of stucco can help you make informed decisions and protect your investment.
