Is It Normal To Have Cracks In Your Stucco Exterior?

Among the different home exterior materials homeowners can choose from, stucco has remained a popular choice for centuries, and for good reason. In addition to lasting for a long time and withstanding harsh weather conditions, this exterior choice offers aesthetic appeal and adaptability to any design aesthetic. However, for all the perks it provides, a stucco exterior often comes with one potential issue: cracks. If you've discovered cracks in your outside walls, it's only natural to wonder what they could mean. When you take into account the cost to renovate the outside of your house, which can run anywhere from $13,500 to $18,000 depending on project complexity and materials, weighing whether these cracks really call for such a splurge makes sense. The good news is that hairline cracks in your stucco are a common occurrence, and their impact on your home is usually limited to aesthetics.

Small cracks typically aren't a cause for concern, especially if you live in a harsh climate or your home is of older construction. Cracks might also appear as your home's foundation naturally settles. Most of the time, these cracks don't affect structural integrity, and you can fill them in with caulk by yourself. Still, even small cracks can develop into a bigger issue if not properly assessed and addressed.

Cracks in your stucco cross the line of merely a cosmetic issue and into more dangerous territory when they're wider than 1/16 inch. Cracks of this kind could indicate structural damage to your home, and they can happen for various reasons. For one, rushed construction could be slowly damaging your home, as poorly installed stucco tends to break apart more easily and form larger cracks. Excess moisture is another common culprit, as is extreme weather. Your home could also be settling more quickly or forcefully, leading to larger cracks.

Whatever the reason behind a larger crack may be, it's important to get your home's exterior professionally examined and repaired. If you leave large cracks untreated, you're exposing your home's exterior to mold and rot from moisture seeping in through the cracks, as well as further structural damage as it continues to widen.

While small cracks aren't the end of the world, prioritizing your stucco exterior upkeep goes a long way in preventing more serious issues down the line. Regularly checking your home's exterior for new cracks or keeping an eye on existing ones can help nip potential issues in the bud before they escalate to costly repairs. Making sure your stucco is properly installed with quality materials can help reduce the likelihood of cracks forming due to construction issues. Finally, consistent cleaning and proper drainage can stop the cracks from worsening due to excess moisture or debris buildup.
