Alright, let's talk about stucco installation. I've been doing this for a long time here in San Dimas, and I've seen a lot of projects go sideways before they even start because folks make some pretty basic, but costly, mistakes. You're investing a good chunk of change into your home's exterior, so you want to get it right. Here's what I see most often that you absolutely need to watch out for.
Mistake #1: Focusing Only on the Lowest Bid
I get it, everyone wants a good deal. But when it comes to stucco, the lowest bid is almost never the best bid. Think about it: if one contractor is significantly cheaper than everyone else, where are they cutting corners? It could be in the quality of materials, the experience of their crew, or skipping crucial prep steps. Good stucco isn't cheap, and cheap stucco isn't good. You're looking for value, not just a low price tag. A proper stucco job protects your home, helps with insulation, and looks great for decades. A cut-rate job? That's a recipe for cracks, water intrusion, and needing a re-do in just a few years. And trust me, fixing bad stucco costs way more than doing it right the first time.
Mistake #2: Not Understanding the Stucco System
A lot of homeowners think stucco is just a layer of cement slapped on a wall. It's not. Modern stucco, especially here in Southern California where we deal with temperature swings and occasional heavy rains, is a system. It includes a proper weather-resistive barrier (WRB), lath, weep screeds, corner beads, control joints, and multiple layers of material. Each part plays a critical role in keeping water out and your home protected. If your contractor isn't talking about these components, or worse, doesn't seem to know what they are, that's a huge red flag. You need a contractor who understands the science behind it, not just how to apply it. We've seen homes, especially some of the older ranch-style places around the San Dimas Canyon area, where original stucco wasn't installed with modern WRB standards, leading to issues down the line. A new installation should always address these.
Mistake #3: Skipping the Prep Work
This goes hand-in-hand with the lowest bid problem. Proper preparation is absolutely critical for a long-lasting stucco job. This means things like:
- Thorough cleaning of the existing surface (if applicable).
- Repairing any underlying structural issues.
- Properly installing the WRB and lath.
- Making sure all windows, doors, and penetrations are flashed correctly.
If a contractor is rushing through this, or telling you they can skip steps to save money, they're setting you up for failure. The foundation of your stucco job is just as important as the finish. Without good prep, you'll see cracking, delamination, and water problems much sooner than you should.
Mistake #4: Not Checking References or Licenses
This one seems obvious, but you'd be surprised how many people don't do their homework. Always, always, always check a contractor's license with the CSLB (Contractors State License Board). Make sure it's active and in good standing. Ask for references from recent jobs, and actually call them. Ask about their experience, whether the job stayed on budget, if there were any issues, and how they were resolved. A good contractor, like us at Absolute Stucco, will be happy to provide these. If they hem and haw, or can't give you any, walk away. You're letting someone work on your biggest asset; don't take chances.
Mistake #5: Ignoring Control Joints
This is a big one for long-term durability. Stucco, like almost any building material, expands and contracts with temperature changes. Without properly placed control joints, that movement has nowhere to go, and you'll get unsightly and potentially damaging cracks. These aren't just cosmetic; they can be entry points for water. A good contractor will plan for these joints, especially on larger, uninterrupted wall surfaces. If they're not discussing where these will go, or worse, telling you they're not necessary, you need to question their expertise.
Getting new stucco is a big project, and you want it done right. By avoiding these common mistakes, you'll be well on your way to a beautiful, durable exterior that protects your home for years to come.
