Lath replacement in Bonita, CA.
Lath replacement for Bonita homes, done by licensed San Diego County stucco crews. Corroded metal lath is the structural failure mode that cracks and patches cannot fix. When salt air, chronic moisture intrusion, or age has rusted the galvanized wire mesh that the stucco is keyed into, no amount of surface repair will hold.
Why is lath replacement different in South County San Diego?
Chula Vista, National City, and Imperial Beach homes from the 1950s and 1960s have original lath systems that are at or past end of life, and the combination of age and salt-adjacent humidity accelerates corrosion at the base of the walls. The insured crews we connect you with in South County replace weep screed and building paper at the same time as lath, since these components are all part of the same moisture management system and replacing lath without addressing weep screed failures results in a repeat moisture intrusion problem. Permit and inspection requirements for lath replacement in Chula Vista and National City follow the same sequence as San Diego proper, with a lath inspection required before the scratch coat. Stucco removed during lath replacement in this area sometimes reveals deteriorated OSB sheathing that needs to be replaced before new lath can be installed.
What's included in lath replacement in Bonita?
- Probe and tap test the stucco to map the extent of lath failure and delamination before demolition begins
- Remove stucco in the affected area down to the sheathing, taking care not to disturb framing or window and door rough openings
- Inspect the sheathing, sill plates, and any moisture barriers beneath the removed stucco for rot or damage
- Install new galvanized self-furring metal lath at the specified overlap and fastener spacing, with new Grade D building paper or housewrap lapped correctly at seams and penetrations
- Apply the scratch coat over the new lath with proper embedment so the stucco keys into the mesh
- Apply the brown coat and finish coat in sequence with required cure windows between each layer
When does a Bonita home need lath replacement?

- A contractor has opened a wall section and confirmed corrosion of the existing lath
- A home built in the 1950s or 1960s near the coast or with a history of moisture intrusion

How do I know if my lath needs replacing?
The most reliable field test is tapping the stucco with a hard object in a grid pattern. Sound stucco produces a dense thud; delaminated stucco over corroded lath produces a hollow sound. Rust staining through the finish coat, widespread cracking that follows a grid pattern, and large areas of stucco that have fallen away entirely are all signs of lath failure. The crews we connect you with confirm lath condition in the in-home assessment.
Can lath corrosion spread if left alone?
Yes. Water that has gotten behind the stucco continues corroding the lath, and corroding lath loses its grip on the stucco above. The delaminated area grows over time. The sheathing and framing beneath are also at risk once moisture has a pathway through the stucco system. Addressing lath failure early is less costly than waiting until the damage extends to the structure.
