Walking around the Chapman neighborhood or out near Bidwell Park reveals cracks running through the exterior walls of older homes in Chico, California. Stucco is very durable, but it is not invincible, especially out here in the valley where the ground moves and the summer sun beats down. Homeowners often do not think about their exterior walls until a winter storm rolls in off the Sierra foothills and drives rain straight into those tiny fissures. What starts as a cosmetic nuisance turns into a real problem with moisture getting trapped behind the lath.
The Chico Soil Factor
Building down in Butte County involves understanding the local soil, which contains a whole lot of clay. Bone-dry spells in August and September cause the earth to shrink up. Winter rains then hit, causing the ground to swell right back up and shift the foundation just a fraction of an inch. Stucco does not bend. When the house moves, the plaster cracks. Older homes in the South Campus area or up near the avenues often show these stress patterns around window corners and door frames. The movement is common, but ignoring it creates risks for the structure.
Fixing the Problem Before It Spreads
Chico Stucco & Plastering knows that property owners cannot just slap a glob of cheap caulk over a stucco crack and call it good. That approach traps water and makes the surrounding material crumble faster. Chico Stucco & Plastering has spent many years cutting out damaged sections, checking the wire lath underneath for rust, and feathering in fresh mixes that match the original texture of the wall.
- Small hairline fractures need a specialized elastomeric patch that stretches with the wall.
- Deader, hollow-sounding areas usually mean the bond has failed completely and needs a complete tear-out.
- Matching heavy dash or Spanish lace finishes takes a practiced hand, not a roller from the big box store.
