Stucco Patching in Boerne, TX
Stucco patching restores cracked, delaminated, or water-damaged sections of a stucco wall back to a sound, weathertight surface without replacing the entire system. Homeowners in Boerne, TX notice the problem as hairline map cracking, hollow-sounding sections when tapped, staining at the base of the wall, or patches of finish coat that have pulled away from the substrate. Because roughly 16 percent of Boerne's housing units were built before 1980 and the area sees about 32.4 inches of rain annually with May averaging 4.4 inches as the wettest month, older stucco walls face repeated wet-dry cycles that open cracks and drive moisture behind the cladding. Patching those failures early protects the structure and preserves the median home value of $464,100 that owner-occupied households in this community have built.
Every patch job starts with a thorough tap-test survey of the wall to map drummy, delaminated areas before any material is applied. Failed stucco is cut back to a sound edge with a wet-cutting diamond saw, and the perimeter is undercut so the new patch can key in mechanically. Two layers of grade-D building paper are lapped shingle-style over the existing weather-resistive barrier, and galvanized metal lath is fastened over it. A Portland cement-lime scratch coat is hand-applied with hawk and trowel, scored horizontally, and allowed to cure; the brown coat follows, floated to a true plane and moist-cured to minimize shrinkage cracking. The finish coat is an acrylic-polymer formula tinted and textured on a sample board first to match the existing dash, sand-float, or skip-trowel profile. Control joints are re-cut on the original grid with the diamond saw and sealed with closed-cell backer rod and masonry-grade polyurethane sealant so the repair can move with the wall. Where fine map cracking continues to shift seasonally, an elastomeric crack-bridging coating is applied over the elevation. The weep screed at the base is reset above grade so absorbed water drains out rather than wicking back up through the patch. On walls with a synthetic lamina, an EIFS moisture probe meter is used to survey trapped water before and after the repair to confirm the assembly has dried out. Stainless casing bead and corner aid are installed at window and door terminations to give the patch a clean, durable edge.
Typical pricing for this work in Boerne ranges from $250 to $800 per small crack repaired and textured, $400 to $1,200 per color-matched patch, and $7 to $14 per square foot for a full three-coat re-stucco. Control or expansion joint cutting and sealing runs $4 to $10 per linear foot, weep screed replacement costs $8 to $20 per linear foot, and an elastomeric coating applied to one elevation ranges from $1,200 to $3,500. An EIFS moisture probe inspection survey is priced at $350 to $1,200. Complete stucco repair projects typically fall between $1,500 and $9,000 depending on scope. Boerne's dominant Barbarosa silty clay loam soil is well drained, but the seasonal temperature swing of roughly 54 degrees Fahrenheit between January lows averaging 41 degrees and July highs averaging 94.9 degrees creates significant expansion and contraction stress on stucco assemblies, making properly cut and sealed control joints especially important here. On the permitting side, contractors must be registered with the City of Boerne and submit any required permit applications through the city's My Government Online portal before work begins; the Permitting and Code Compliance Department at 447 N. Main Street enforces the 2021 International Residential Code and the 2021 International Building Code and conducts inspections of construction projects within city limits. Questions about permit requirements can be directed to that department at (830) 248-1529.
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.
