Frequently Asked Questions

Why Does Stucco Crack?

A. Cracks in stucco can occur due to different factors, including wrong mix proportions, insufficient mixing, poor workmanship, seismic movement and seasonal changes. Other leading causes of cracks in stucco are the house settling process and shrinkage-induced stresses, which typically occur during the drying period.

When should I “really” worry about stucco cracks?

A. Some are more serious than others, usually a good rule of thumb is the size and depth of the crack. If it is more than 1/16 of an inch wide, then it should be addressed with a stucco contractor.

How long does stucco last?

A. With proper maintenance, stucco can last anywhere from 50 to 80 years, in many cases, a lifetime! Just be sure to repaint and recaulk your home every four to five years and regularly inspect for cracks.

What do you put under stucco?

Sheathing is basically the “backing material” that can be found underneath the various layers of stucco that form the backing of residential and commercial buildings. They can be made out of wood, cement, gypsum, fiberglass and other materials. In between the sheathing and stucco there should be a weather resistant barrier (WRB) to prevent water from damaging exterior walls.

What stucco services does MXL Wall Systems provide in South Florida?

MXL Wall Systems offers comprehensive stucco installation and repair services for both residential and commercial properties throughout South Florida. Our services include new stucco applications, full re-stucco projects, crack and damage repairs, EIFS (synthetic stucco) systems, and exterior refinishing. We tailor every project to withstand Florida’s heat, humidity, and heavy rain while delivering a clean, modern finish that enhances curb appeal and long-term durability.

What is EIFS and how is it different from traditional stucco?

EIFS (Exterior Insulation and Finish System) is a lightweight, multi-layer exterior wall system that includes built-in insulation, a moisture barrier, reinforcing mesh, and a decorative finish coat. Unlike traditional cement stucco, EIFS improves energy efficiency and moisture control. It provides better insulation performance and can help regulate indoor temperatures, which is especially beneficial in South Florida’s warm climate.

How does stucco protect my home from South Florida weather?

Properly installed stucco exterior systems create a durable, weather-resistant barrier that helps protect your property from wind-driven rain, humidity, and intense sun exposure. Our systems include moisture barriers and drainage features to prevent water intrusion, reducing the risk of mold or structural damage. When installed correctly, stucco performs exceptionally well in coastal and hurricane-prone environments.

Is stucco energy efficient for Florida homes?

Yes. Modern energy-efficient stucco systems, especially EIFS, include insulation that helps reduce heat transfer into your home. This can lower cooling costs and improve overall comfort during Florida’s hot summer months. When combined with proper ventilation and building envelope practices, stucco can contribute to better indoor temperature control and energy savings.

Are your stucco installations compliant with Florida building codes?

Absolutely. All of our Florida Building Code-compliant stucco work meets or exceeds state requirements for wind resistance, moisture protection, and structural integrity. South Florida has strict regulations due to hurricane exposure, and we follow all local and state guidelines to ensure your project passes inspections and performs reliably under extreme weather conditions.

Do you work on commercial properties as well as residential homes?

Yes. MXL Wall Systems handles both commercial and residential stucco projects across South Florida. We work with homeowners, property managers, builders, and developers on projects ranging from single-family homes to apartment complexes, office buildings, retail centers, and industrial properties. Our team is equipped to scale projects efficiently while maintaining high-quality craftsmanship.

How long does a typical stucco installation take?

The timeline for a stucco installation project depends on the size and condition of the property. For an average single-family home, installation may take approximately two to three weeks, including preparation, layering, curing time, and finishing. Larger commercial properties may require additional time. We provide a clear project schedule upfront so you know what to expect.

Do you offer warranties on stucco or EIFS work?

Yes. We stand behind our craftsmanship with a stucco workmanship warranty that covers installation-related issues. Warranty details vary depending on the project scope, and we clearly outline coverage during the proposal process. We also use high-quality materials that may carry manufacturer warranties for added peace of mind.

How should I maintain my stucco exterior?

Stucco is relatively low maintenance, but routine care helps extend its lifespan. To maintain your stucco exterior finish, inspect annually for cracks, clean surfaces gently to remove dirt or mildew, and reseal joints as needed. Repainting or applying an elastomeric coating every several years can help preserve appearance and protection against South Florida’s harsh sun and moisture.
