Stucco Patching in Cumming, GA
Stucco patching restores cracked, delaminated, or water-damaged sections of your exterior walls without tearing off the entire cladding system. Whether you have a handful of map cracks that open and close with the seasons, a drummy patch that sounds hollow when tapped, or a color-faded section where an old repair never quite blended in, targeted stucco patching brings the wall back to a sound, weathertight, and visually consistent finish. Homeowners with aging synthetic or traditional three-coat stucco, and anyone who has noticed efflorescence or staining near the base of a wall, are the most common candidates for this service.
Every patching job starts with a thorough tap survey of the wall surface. A technician sounds the stucco by tapping across it to map every drummy or delaminated area before a single patch goes on. Failed material is then cut back to a sound edge using a wet-cutting diamond saw, and the perimeter is undercut so the new patch keys mechanically into the existing stucco. Fresh galvanized metal lath and two layers of grade-D building paper are lapped shingle-style over the existing weather-resistive barrier, and the weep screed at the base of the wall is reset so absorbed water drains out rather than wicking upward. The repair then follows the full Portland cement-lime three-coat sequence: a scored scratch coat allowed to cure, a brown coat floated to a true plane and moist-cured to limit shrinkage, and an acrylic-polymer finish coat tinted and textured to match the surrounding wall. Texture matching—whether dash, sand-float, or skip-trowel—is tested on a sample board before it ever touches the house. Control joints are re-cut on the original grid and sealed with closed-cell backer rod and masonry-grade polyurethane sealant. For walls with fine map cracking that moves seasonally, an elastomeric crack-bridging coating is an additional option. On EIFS cladding, a moisture probe meter survey is performed after the repair to confirm the assembly has dried out.
Typical pricing for this area runs $250–$800 per small crack repaired and textured, $400–$1,200 per color-matched patch, and $7–$14 per square foot for sections requiring full three-coat re-stucco. Weep screed replacement runs $8–$20 per linear foot, control or expansion joint cutting and sealing runs $4–$10 per linear foot, and an elastomeric coating applied to a full elevation ranges from $1,200 to $3,500. Complete stucco repair projects typically fall between $1,500 and $9,000 depending on scope. The local climate is a key driver of repair urgency: with roughly 50.4 inches of annual precipitation, a rainy season running January through March, and a seasonal temperature swing of about 54 °F between the January average low of 35.6 °F and the July average high of 90.1 °F, stucco here is subjected to repeated wet-dry and freeze-thaw cycling that widens cracks and drives moisture behind the cladding. The dominant Habersham soils in this area are well drained, which limits hydrostatic pressure at the foundation, but proper weep screed placement remains important for managing the water that does penetrate the wall assembly during heavy rain events.
Frequently Asked Questions
How long does a typical stucco repair take?
A crack repair or a single patch is often a one- to two-day job including texture and cure time. Re-stuccoing a full elevation runs several days because each coat has to cure before the next, and finish work waits on weather.
What is a weep screed and why does it matter?
A weep screed is the metal flashing at the bottom edge of a stucco wall that lets any water inside the system drain out above grade. Code requires it to sit a set distance above the ground. If it is buried or missing, water wicks up into the stucco and the base of the wall starts to fail.
My stucco sounds hollow when I tap it — what does that mean?
A hollow or drummy sound means the stucco has lost its bond to the lath behind it, usually from water getting in. That area is no longer protecting the wall and needs to be cut out and rebuilt, not just skim-coated over the top.
Can stucco be repaired in the winter?
Cement and finish coats need temperatures to stay above about 40 degrees while they cure, and a hard freeze the first night will ruin a fresh coat. We can do many repairs in cold months with protection, but final finish coats are scheduled for the warmer, drier part of the year.
How much does stucco repair cost?
It varies with the damage. A small crack or single patch typically runs a few hundred dollars up to about $1,200, while re-stuccoing an elevation runs roughly $7 to $14 a square foot installed. A whole-house re-stucco or an EIFS moisture remediation reaches the higher end.
Will painting my stucco stop the cracks?
Ordinary paint will not, and it can make things worse by sealing moisture inside the wall so it spalls behind the film. Hairline map cracking can be bridged with a breathable elastomeric coating, but active or structural cracks have to be opened and repaired first.
