Stucco is a very tough material, but the clay-heavy soils and morning fog in Los Altos, CA can take a toll on exterior walls over time. If you want to catch small problems before they turn into expensive structural issues, you have to know what to look for during an inspection. Mighty Stucco Solutions has put together a straightforward guide on how to check your own stucco, what you can safely handle yourself, and when it is time to call a professional stucco contractor for Stucco Repair in Los Altos, CA.
Before You Start Looking
You do not need a cart full of expensive tools to do a basic visual check of your home exterior. Grab a notebook, a flashlight, and a camera to snap photos of anything unusual on your Stucco. Clear away any tall shrubs, ivy, or stacked firewood sitting right against your walls. Stucco needs to breathe, and Mighty Stucco Solutions regularly sees moisture trapped behind overgrown landscaping in neighborhoods up near the Los Altos Country Club. Make sure you can actually see the bottom six inches of your walls where the Stucco meets the foundation.
During the Inspection: What to Look For
Start from the ground and work your way up. Look closely at these common trouble spots during your Stucco inspection:
- Hairline cracks that are smaller than a credit card—these are usually normal settling, but keep an eye on them.
- Dark stains or greenish mold running down from window sills, which usually means water is not shedding away properly from the Stucco.
- Bulging or soft spots when you gently press on the surface near roofs and doors.
- Cracks wider than a pencil, especially if they run diagonally from the corners of your windows.
That diagonal cracking near window frames is a red flag for Stucco walls in Los Altos, CA. It usually means movement or water intrusion behind the weather-resistive barrier, and painting over it will not fix a thing. Use your flashlight to check dark corners and areas shaded by large oak trees where moisture lingers longer after a heavy rain.
What You Can Do Yourself
If you spot minor hairline cracks during your walkaround, you can seal those up with a high-grade elastomeric masonry patch on a dry afternoon. Power washing is another task you can tackle if you keep the pressure low and spray downward—never blast water straight up or sideways into Stucco joints, or you will force moisture right through the wall assembly. Keeping your gutters clean and your sprinklers angled away from the house is the best preventative maintenance you can do on your own to protect your Stucco.
When to Call a Pro
The moment you find soft, spongy Stucco, crumbling corners, or wide structural cracking, put the DIY tools down. Moisture meters and thermal imaging are often needed to figure out how far water has traveled behind the scratch coat and brown coat. If you suspect water is getting behind your walls, call Mighty Stucco Solutions for Stucco Repair in Los Altos, CA before minor weather damage turns into a full-scale framing replacement. Catching these issues early keeps your home solid and saves you thousands down the road. For homes and businesses in Los Altos, Mighty Stucco Solutions provides Stucco Repair services.
