CA fam ?—ever heard of the “10 Biggest Renovation Regrets”? #7 is a total trap that’s wrecked 90% of folks I know. My bestie just texted crying: her new kitchen walls are moldy, floors are buckling, and she’s out $30K fixing it. Let’s be real: stop believing “CA is too dry for moisture control”. Especially if you’re in SF (fog city) or LA (rainy Nov-Mar)—painting walls with regular paint is basically rolling out a red carpet for mold. My neighbor’s walls last year? Peeling like a bad sunburn, and her oven grew mold (gross, I know). Here’s the fix: ❶ Walls: Moisture-blocking primer + anti-mold paint (Sherwin-Williams’ “MoldBlock” is CA mom-approved). ❷ Floors: Water-resistant composite wood (skip cheap solid wood—it swells when humidity hits). ❸ Wet areas (kitchen/bath): Mini dehumidifier (Amazon “CA dehumidifier” under $100 saves your walls!). No one wants renovation regrets, but dodging this? Saves you 30% in repair cash. Let’s enjoy CA sun and fog—without mold crashing the party. ?️
