Stucco is very tough, but stucco is not invincible, especially with the way our dry inland heat and occasional winter downpours test exterior walls here in Rancho. If homeowners have not taken a close look at their home siding in a while, they are overdue for a walk-around. Pacific Stucco Co sees homeowners every week who wait until water is actually leaking inside before they notice a problem, and by then, a simple patch job has turned into a major headache. This practical guide explains how to inspect your own stucco, what you can safely handle yourself, and when it is time to bring in some backup in Rancho, CA.
Before You Start Your Stucco Inspection
You do not need a truckload of expensive gear to check your stucco, but you do need a few basic items before you step outside. Grab a clipboard, a notepad, a magnifying glass for looking closely at hairline fractures, and a standard metal coin or a blunt tool. Timing matters too. Pick a bright, clear morning when the sun hits your exterior walls at an angle. Direct overhead noon sun washes out shadows, making hairline cracks nearly impossible to spot against our typical light-colored desert and Mediterranean palettes in Rancho.
The Walk-Around: What You Can Do Yourself
Start at the front corner of your house and work your way all the way around the perimeter. You are looking for changes in the surface texture, discoloration, or any breaks in the finish.
- Hairline cracks under an eighth of an inch are common as settling happens, but keep an eye on them.
- Check around every window frame and door trim, since those sealant joints fail first.
- Look near the base of the wall where the stucco meets the concrete foundation or soil, making sure dirt and mulch are not piled up against the siding.
If you spot minor spiderweb cracking, you can usually clean out the loose debris, let it dry completely, and apply a high-grade elastomeric masonry patching compound using a small putty knife. That is a totally DIY-friendly weekend chore that keeps moisture out of your stucco.
When to Put Down the Tools and Call a Pro
Not everything can be fixed with a tube of caulk and a putty knife. If you tap on the stucco with your coin and hear a hollow, booming sound instead of a solid thud, you have likely found an area where the scratch coat has delaminated from the lath behind it. That means the bond has failed, and patching the surface will not cut it. You also need to call in professionals like Pacific Stucco Co if you see dark, rust-colored stains bleeding through the finish coat, which usually points to corroded metal lath rusting away inside the wall assembly.
After the Inspection: Making Your Game Plan
Once you finish your circuit, map out your findings on your notepad. Jot down which elevations have the most weathering, usually the south and west sides that take the brunt of our intense afternoon sun. If you found minor cosmetic issues, knock them out this weekend while the weather is dry. If you found bulging walls, soft spots, or widespread cracking that spans multiple feet, snap a few clear photos and reach out to Pacific Stucco Co for Stucco Repair services in Rancho, CA before the next rainstorm hits our area.
