In the Hill Country and West Texas, stucco is a popular choice for exterior home siding for a southwestern aesthetic. Made of Portland cement, sand, lime, and water, the mixture is applied on water-resistant paper in layers, over a lath base. When properly dried, it offers solid, durable, and seamless house siding.
Especially in environments of extreme heat, stucco provides several advantages:
But, while water-resistant, it is not waterproof. It is actually absorbent. And in the Hill Country, our humidity will amplify and accelerate water damage that gets started behind the stucco. In most cases, leaks through stucco occur when the building envelope has been breached. For example, water might enter a home’s exterior via rusted nails, leaky roofs, tears in the building paper, or deteriorated edges.
During a wind-driven rainstorm, water quickly absorbs through the stucco layers. You might notice that the sides of the house will take hours and sometimes even days to completely dry out. If significant moisture gets behind the stucco, it could soften the areas and cause the material to fall off in sheets.
If you see staining around the corners of windows or doors, the leak is rarely caused by the windows or doors themselves. It is probably due to improper (or missing) flashing. For most areas in the west, southern exposures are where most of the seasonal, wind-driven rain comes from, and most of the corresponding window and door leaks are found.
You might notice dark spots or discoloration on your stucco walls from trapped moisture When this building material is left damp or wet, mold will form. Whether it’s on an external surface or hiding beneath the stucco, mold must be managed. It can have a negative impact on your health: allergic reactions, headaches, increased asthma problems, or even respiratory damage.
Since stucco is water-resistant, not waterproof, even the smallest crack can allow water into the wall. Over time, this area will eventually require repairs. Always make any plumbing repairs as soon as possible: burst pipes, weather damage, or plumbing leaks. Keep Restoration 1 of Texas Hill Country on speed dial whenever you notice a problem.
Proper installation of water-resistive barrier materials, flashing, and weep screeds will help protect the home. Liquid water-resistive barriers must be applied according to 1) the manufacturer’s specifications 2) at the ambient temperature recommended or on a sufficiently clean substrate and 3) at the required thickness to properly seal the stucco substrate.
Restoration 1 of Texas Hill Country’s team might suggest a silicate mineral paint to seal out water but still allows any trapped water vapor to escape. Painting your stucco every 5 or so years protects the entire house and its components from water absorption.
If you have already tried re-sealing or painting the stucco and then noticed leaks, the Restoration 1 team will probably recommend removing the entire wall and installing new windows with premium flashing and new stucco. Have Restoration 1 of Texas Hill Country take a deep look. Those visible cracks aren’t the only potential sources of entry for water.
