Stucco Lath & Mesh Repair in Las Cruces, NM

Stucco lath, sometimes called wire mesh, is the metal reinforcement layer installed underneath stucco that the material actually bonds to. When lath rusts, tears, or separates from the wall, the stucco above it loses its structural support, which is a different and more serious problem than a surface-level crack. Lath and mesh repair addresses this underlying layer directly, not just the visible stucco on top of it.

If you are searching for stucco lath or mesh repair, you are usually dealing with a wall that has bulging, hollow-sounding stucco, visible rust staining, or an area where previous water damage has been sitting long enough to compromise the metal underneath.

Signs of Lath or Mesh Damage

• Rust staining bleeding through the stucco surface
• Bulging or hollow-sounding sections when tapped
• Stucco that has separated or is visibly loose from the wall
• Recurring cracking in the same spot after previous surface-only patches

How Lath & Mesh Repair Works

Removing the Damaged Section

The affected stucco is removed to expose the lath underneath, so the actual extent of rust or damage can be assessed rather than guessed at.

Replacing the Wire Lath

Damaged or rusted lath is cut out and replaced with new wire lath, properly overlapped and fastened into the surrounding sound material.

Addressing the Moisture Source

Since rusted lath is almost always caused by water getting behind the stucco, we check for the moisture source itself, not just the visible damage, to prevent the same failure from happening again.

Rebuilding the Stucco Layers

Once the lath is repaired, the scratch coat, brown coat, and finish coat are rebuilt in the correct sequence and texture-matched to the surrounding wall.

Why Lath Damage Happens Here

Monsoon storms from July through September push water into any existing gap in the stucco surface, and once moisture reaches the wire lath, rust can develop over time. Combined with the constant heat cycling that stresses stucco throughout the year, small entry points for water tend to grow into real lath damage if left unaddressed.

Related Services

If the damage is limited to the surface with no rust staining or hollow spots, standard crack repair and patching may be sufficient. For water damage specifically, see our stucco water damage repair page. If lath issues are widespread across the home, full stucco replacement may be the more practical option.

Frequently Asked Questions About Stucco Lath & Mesh Repair

How do I know if my stucco has lath damage versus a surface crack?

Rust staining, bulging, hollow-sounding areas, or stucco separating from the wall all point to lath damage rather than a simple surface crack. An in-person inspection can confirm which you are dealing with.

What causes stucco lath to rust?

Water getting behind the stucco through cracks, gaps, or failed flashing is the most common cause. Once moisture reaches the metal lath, rust can develop and weaken it over time.

Can lath be repaired without removing all the stucco?

Only the affected section needs to be removed to access and replace damaged lath, provided the surrounding stucco is still sound.

Will the repaired area match the rest of my stucco?

Yes, texture and color matching is part of rebuilding the stucco layers after lath repair, so the patch blends with the surrounding wall.

Do you offer free inspections for suspected lath damage?

Yes. We inspect the area in person, since lath damage often needs a closer look than water damage-adjacent symptoms alone can confirm.
