What Causes Normally Durable Stucco to Fail?

Homeowners choose stucco due to its many benefits, such as low cost, limited maintenance, increased equity, appearance, and beauty. Despite its usual durability, overtime some factors may lead to problems developing with your stucco. Commonly, these malfunctions arise as a result of improper installation, temperature extremes, improper mixing, or environmental causes.

Due to the components that make up stucco (cement, lime, and sand) the resulting products is extremely porous. Thus, it is a surface that easily retains excess moisture that may lead to the development of cracks. If left uncorrected, cracks can snowball into more serious issues like broken sections, mold, mildew, interior rot, paint problems, and water damaged drywall.

No matter what combination of factors led to problems developing with your stucco, water is typically a factor in all of them. If stucco is not protected against penetrating water, the stucco itself and the structure behind it may become damaged. Thus, it is imperative that you regularly conduct an invasive moisture test to identify and correct any issues early on.

It is always advisable to only allow a contractor who is specifically trained and experienced in how to professionally install stucco to complete the job. This will ensure it is fully waterproofed and will stand up against moisture. Continue reading to learn more about the most common issues that arise with stucco siding.

Window and Door Issues

Windows and doors that are not properly installed are common culprits that cause damage to stucco. Simply put, if windows are not sealed correctly, water can make its way in and create rot and mold issues. When water penetrates behind your stucco it will inevitably begin cracking, causing subsequent damage to the structural integrity of your home.

Flashing Is Crucial

It is important that the installer doesn’t forget to install flashing diverters and does so correctly to avoid serious negative impacts on your stucco. These important pieces help move water in the direction of your gutters.

Seal It Up

Any entry point that is not sealed correctly creates an area of vulnerability in your stucco. It is important that dryer vents, outlets, piping, and lights are installed correctly to avoid the issue of moisture. Anywhere an entry exists, it is crucial to have it sealed internally and have water management in place to divert moisture away from the area.

A Deck Done Right

Add-ons, such as decks can cause damage to the underlying stucco if improperly installed. It is important that the contractor installing your deck is experienced in working with stucco. He or she must be cautious to use adequate ledger board drip cap flashing, barrier membranes, and rain screens to protect the stucco beneath. This ensures moisture is properly diverted.

A Seamless Transition

It is not uncommon for stucco homes to boast of other materials, such as brick, concreate, stone, or even sections of siding. However, problems can quickly arise if your contractor is not skilled in sealing areas of transition. When expansion and contraction is not accounted for ahead of time, sealing will fail and create issues with cracking and subsequent water damage. Flashing is also crucial to divert water from penetrating your stucco.

Despite the possibility of malfunctions, stucco can be a long-lasting, durable option if done properly. Ensure your contractor is building quality that will stand the test of time!
