You own a business here in Ontario, CA, and you've got stucco on your building. That's a smart choice for durability and curb appeal, but it also means you need to think about how our local climate impacts it. I've been doing this for a long time, and I've seen firsthand what our hot, dry summers and occasional wet winters can do to commercial stucco. It's not just about aesthetics; it's about protecting your investment and keeping your business looking professional.
When to Schedule Your Stucco Work
Timing is everything when it comes to stucco. Ideally, you want to avoid the extremes. For new installations or major repairs, spring and fall are your best friends. The temperatures are usually mild, and we don't have the intense heat that can dry out stucco too quickly, or the heavy rains that can wash it away before it cures properly.
If you're thinking about a big project, like a full re-stucco, try to get it on the books for April-May or September-October. That gives the material plenty of time to set and cure without being stressed by 100-degree days or unexpected downpours. We're not talking about the kind of torrential rain you see back east, but even a few days of consistent drizzle can slow things down and affect the finish.
Weather Conditions That Affect Stucco Application
Our weather here in the Inland Empire is pretty predictable, but there are always nuances. High heat, for example, is a big one. When it's scorching hot, stucco can dry out too fast. This leads to cracking, and not the good kind that adds character. It's structural, and it compromises the integrity of the finish. We'll often use special additives or techniques to slow down the drying process on those really hot days, or we'll adjust our work schedule to start earlier in the morning.
Wind is another factor. We get those Santa Ana winds sometimes, especially in the fall. Strong winds can dry out stucco quickly, just like heat. They can also blow dust and debris onto a fresh application, which is a headache to clean up and can ruin a smooth finish. It's something we always keep an eye on when we're planning a job. And while snow is rare here, the occasional cold snap means we need to be mindful of temperatures dropping below freezing, which can also affect curing.
Protecting Your Commercial Stucco Year-Round
Once your stucco is in place, you can't just forget about it. Regular maintenance is key to making it last. Here's what I recommend to my commercial clients:
- Routine Inspections: Walk around your building a couple of times a year. Look for hairline cracks, chips, or any signs of moisture intrusion, especially around windows, doors, and rooflines. Catching these small issues early can save you a lot of money down the road.
- Keep it Clean: Stucco can get dirty, especially if your business is near a busy street or in an industrial area. Dust, grime, and even mildew can accumulate. A gentle power wash (low pressure!) or a good scrubbing with a soft brush and mild detergent can do wonders. Just be careful not to blast water directly into any cracks or openings.
- Address Water Issues: This is probably the most critical point. Our stucco is built to handle our dry climate, but it's not invincible against constant moisture. Make sure your gutters are clean and directing water away from your building. Check your irrigation system to ensure sprinklers aren't constantly soaking the stucco near the ground. I've seen too many cases where a leaky downspout or an overzealous sprinkler system caused significant stucco damage on commercial properties in areas like the Airport Business Center.
- Seal and Paint (When Needed): If your stucco is painted, you'll eventually need to repaint it. A good quality elastomeric paint can add an extra layer of protection against moisture and UV rays. If your stucco isn't painted, consider a clear sealant. It's not a permanent fix, but it can extend the life of your finish.
- Don't Ignore Small Cracks: Those little hairline cracks might seem harmless, but they're entry points for water. Water gets in, expands when it freezes (even if it's just a few cold nights), and then you've got bigger problems. Get them filled and sealed promptly.
Look, your commercial building is a huge asset. Taking care of its exterior, especially the stucco, isn't just about looking good for your customers; it's about preserving the structural integrity and value of your property.
