Stucco Repair Cost Calculator

Stucco repair typically costs $400 to $3,000 for most jobs, with most homeowners paying around $800 to $2,000 — though minor crack repair can be a few hundred dollars, while extensive damage (large areas, water or structural issues, full section replacement) can run several thousand dollars or more. On a per-square-foot basis, stucco repair runs about $10 to $30+ per square foot of the damaged area being fixed (not the whole wall). The price is driven by the damaged area, the repair type (crack filling/patching ~$10/sq ft is cheapest, resurfacing/re-coating a section ~$18/sq ft is mid-range, and removing and replacing a section — rebuilding the three stucco coats over new lath ~$30/sq ft — is the most thorough and expensive), the damage severity (minor hairline cracks vs. severe water/structural damage), and the stucco type (standard finish, a custom/decorative texture that's harder to match, or specialized EIFS/synthetic). A ~$400 minimum service charge applies. Add-ons like repairing water damage behind the stucco, replacing the wire lath, and repainting the wall to match add to the total. Timely repair prevents water intrusion and further damage. Enter your damaged area, repair type, severity, and stucco type above for a localized estimate.

Stucco cracks and damage come from several causes, and identifying the cause matters because a repair that ignores it won't last. The most common is settling and structural movement — as a house settles or the foundation shifts, stress cracks the stucco, often around windows, doors, and corners where stress concentrates. Normal curing and shrinkage produce fine hairline or 'spider' cracks that are usually cosmetic. Temperature swings cause thermal expansion and contraction that stresses the surface, and freeze-thaw cycles (water in cracks freezing and expanding) worsen cracks and cause spalling in cold climates. Moisture and water intrusion is the most serious cause: water penetrating through cracks, failed sealant, or bad flashing gets behind the stucco, damaging the lath and sheathing and causing bulging, crumbling, mold, and even structural rot. Poor original installation — wrong mix, inadequate thickness, missing control joints, or a poor moisture barrier — is a frequent root cause of recurring problems. Impact damage chips or holes the stucco, and a lack of control joints leaves the stucco nowhere to move, so it cracks. Cosmetic hairline cracks may just need patching and sealing, but cracks from ongoing movement or water intrusion require addressing the underlying issue. This calculator includes severity options and add-ons for water damage and lath replacement so you can scope the real repair.

It depends on the extent and cause of the damage. Minor to moderate, localized damage is usually best repaired: cracks, small holes, chips, and limited spalling are cost-effectively fixed by crack filling, patching, or re-coating the affected area, and if the underlying lath and substrate are sound, repairing just the surface is the right, economical call — most stucco issues are repairable. Consider replacing larger sections or the whole wall when the damage is widespread (endless patches on a failing wall don't make sense), when water intrusion has rotted the sheathing or lath behind the stucco (the affected stucco must come off to fix the substrate and water barrier, then be re-stuccoed), when the stucco is bulging, delaminating, or pulling away (usually water behind it), or when a systemic installation failure — like an older barrier-type EIFS that trapped moisture — means patching just wastes money. Cost favors repair heavily, but replacement may be necessary to fix a root problem rather than hide it. Appearance is a factor too: many mismatched patches on an old wall can look worse than resurfacing or replacing a full elevation. Get a professional assessment, especially for suspected water damage that can be hidden behind the stucco. This calculator estimates repairs up to section replacement; a separate stucco installation calculator covers full replacement.

A skilled stucco mason can usually match the texture and get close on color, but a perfectly invisible match — especially on older, weathered stucco — isn't always guaranteed, which is why the best results often come from repainting the affected wall. Texture matching is a craft: common finishes (smooth, sand/float, dash, lace, skip-trowel) can be replicated well with the right technique and tools, though intricate hand-applied decorative textures are harder to match exactly. Color is the bigger challenge. Existing stucco has faded and weathered from sun and dirt, so even the 'same' color on a fresh patch reads as newer and different against the aged surroundings. Integrally-colored stucco (color mixed into the finish coat) is especially hard to match, while painted stucco is easier because you can just repaint. The common solution is to repaint the affected wall — or the full elevation to a natural break — after the repair, giving a uniform color that hides the patch; spot-matching color usually shows. This calculator includes both a repaint/color-match-wall add-on and a custom color-matching add-on. For the most seamless result, match the texture with an experienced applicator and plan to repaint the wall, particularly on unpainted, integrally-colored, or heavily weathered stucco.

Water damage behind stucco is serious because it's hidden, progressive, and can be widespread and costly by the time it's found. Water gets in through cracks, failed caulk, or bad flashing around windows, doors, and roof lines, and once behind the stucco it can be trapped against the wall — stucco doesn't let it dry easily, and some systems lack proper drainage. There it rots the wood sheathing and framing, deteriorates the lath, and grows mold, often with no obvious exterior sign until the damage is advanced. Prolonged intrusion can cause real structural damage, and mold is a health and remediation issue. By discovery, it may affect large areas, requiring extensive repair — removing stucco, replacing the substrate and water barrier, treating mold, and re-stuccoing. EIFS (synthetic stucco), particularly older barrier systems without drainage, became notorious for trapping water and causing extensive hidden rot, so EIFS homes especially warrant moisture inspection. Warning signs include cracks around openings, staining, soft or spongy stucco, bulging or delaminating areas, efflorescence, musty odors, or peeling interior paint. If you see them, get a professional moisture inspection (moisture meters, probes, or infrared), fix the water source, repair the substrate, and re-stucco properly. This calculator includes a water/moisture damage repair add-on and lath replacement — catching it early prevents far costlier structural damage.

Most hairline cracks in stucco are cosmetic and normal, not a structural emergency — but they still deserve attention because they're the entry point for water, which is what turns a minor issue into a serious one. Fine 'spider' or hairline cracks commonly appear as stucco cures and shrinks, and from ordinary settling and temperature movement over the years; these are usually surface-level and can be sealed with a flexible elastomeric patching compound or crack filler and painted over. The concern is leaving them open in a climate with rain or freeze-thaw, where water works into the crack, gets behind the stucco, and causes the hidden rot and spalling described above. So the smart approach is to seal hairline cracks promptly as routine maintenance, even though they're cosmetic, to keep water out. What warrants more concern are cracks that are wide (more than about 1/8 inch), growing, stair-stepped, or concentrated around a specific area — these can signal ongoing structural movement, foundation issues, or water intrusion, and should be evaluated rather than just filled. A pattern of recurring cracks in the same spot also points to an underlying cause that patching alone won't solve. This calculator's minor-severity option and crack-patch repair type cover routine hairline crack sealing; step up the severity if the cracking is extensive or water-related.

Minor stucco crack repair is a reasonable DIY project for a handy homeowner — sealing hairline and small cracks with a paintable elastomeric caulk or a pre-mixed stucco patch, then texturing and painting to blend — but patching holes, matching texture, section repairs, and anything involving water damage are better left to a professional. For a simple crack, you clean out the crack, apply flexible crack filler or patching compound, feather and texture it to match, let it cure, and paint. Small chips and holes can be patched with stucco patch material, though matching the surrounding texture convincingly takes practice. Where DIY gets risky: matching a custom or heavily weathered texture and color rarely looks seamless without experience; a section repair requires rebuilding multiple stucco coats over lath with proper curing; and any sign of water damage means the real problem is behind the stucco, where an amateur repair just seals in rot and moisture. The biggest DIY pitfalls are using a rigid (non-flexible) filler that re-cracks, failing to identify the underlying cause, and hiding water intrusion. For routine hairline cracks on a painted wall, DIY can save money; for holes, texture-critical areas, section damage, or suspected moisture problems, hire a pro. This calculator estimates professional repair; for minor sealing you can compare against DIY materials.

It depends on the repair type and, most of all, curing time. A minor crack or small patch repair can be done in a few hours to a day — clean and prep, apply the patch, texture it, and finish, with any painting adding time. A moderate resurfacing or re-coat of a section typically takes about 1 to 3 days including prep, application, curing, texturing, and repainting. A larger section replacement — removing failed stucco and rebuilding the three traditional coats (scratch, brown, finish) — takes several days to a week or more, because each coat needs curing time before the next, and that wait can't be rushed. Repairs that involve fixing water-damaged substrate add time up front for removal, substrate repair, a new moisture barrier, and re-lathing before any stucco goes on. Other factors: texture matching and finishing take care, repainting adds dry time, and stucco work is weather-dependent — temperature, humidity, and rain affect application and curing, so adverse weather causes delays. High or hard-to-reach areas needing scaffolding also slow things down. In short, minor repairs are quick (hours to a day), while multi-coat section repairs span several days to a week+ due to curing. Your contractor can give a firm timeline once they assess the damage.
