Stucco Crack Repair in Boerne, TX
Stucco crack repair addresses the fractures, delamination, and water intrusion that develop when a stucco wall shifts, settles, or weathers over time. In Boerne, where the seasonal temperature range spans roughly 54 °F between January lows and July highs, walls expand and contract enough to open fine map cracks as well as wider structural breaks. Homeowners with color-matched facades, EIFS cladding, or aging three-coat systems who notice cracking, hollow-sounding sections, or staining at the base of a wall are the primary candidates for this service.
Every repair begins with a thorough tap-test survey of the wall surface. A technician sounds the stucco by tapping across it to map drummy, delaminated areas before any patching material is applied. Failed sections are then cut back to a sound edge and undercut so the new patch keys in mechanically. Fresh galvanized metal lath and two layers of grade-D building paper are lapped shingle-style over the existing weather barrier, and the scratch coat is hand-applied with a hawk and trowel, scored horizontally, and allowed to cure before the brown coat is floated to a true plane. The brown coat is moist-cured to minimize shrinkage cracking, and the finish coat is matched to the existing dash, sand-float, or skip-trowel texture on a sample board first. Control joints are re-cut on the original grid with a wet-cutting diamond saw and sealed with closed-cell backer rod and masonry-grade polyurethane sealant. Where fine map cracking continues to move seasonally, an elastomeric crack-bridging coating is applied to the elevation. On EIFS walls, an EIFS moisture probe meter is used after the repair to confirm trapped water has dried out. Weep screed at the base is reset or replaced so absorbed moisture drains out rather than wicking upward.
Typical pricing for this service ranges from $250 to $800 per small crack repaired and textured, and $400 to $1,200 per color-matched patch. Control or expansion joint cutting and sealing runs $4 to $10 per linear foot, while weep screed replacement costs $8 to $20 per linear foot. An elastomeric coating applied to a full elevation ranges from $1,200 to $3,500, and a complete stucco repair project can run $1,500 to $9,000 depending on scope. Boerne's dominant Barbarosa silty clay loam soil is well drained, but the secondary Boerne fine sandy loam series is also present, and any differential movement at the foundation can telegraph into the stucco above, making proper joint repair especially important here.

Frequently Asked Questions
Can you match the color and texture of my existing stucco?
Yes. We mix the finish to your color and replicate the texture on a sample board first. Keep in mind that years of sun and weather lighten the original, so a patch can flash slightly until it weathers in; for a uniform look we sometimes coat the full elevation to a natural break.
Why do you re-cut control joints instead of just filling the cracks?
Stucco expands and contracts with temperature, and control joints are where that movement is supposed to happen. If a wall is cracking on a joint line, filling it solid just forces the crack to reopen next season. Restoring the joint lets the wall move without tearing the finish.
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.
