Frequently Asked Questions

National 2026 guides from HomeGuide and HomeAdvisor put most stucco repairs at roughly $500 to $2,700, or about $8 to $50 per square foot for typical crack and patch work. Water-damage repair that removes stucco and sheathing runs much higher, around $30 to $50 per square foot or more. Your written estimate, after we see the wall, is the price.

The best repair matches the existing stucco and fixes whatever let water in. Small hairline cracks can be filled with a compatible elastomeric patch; larger cracks and damaged areas are cut out and rebuilt with base coats and a finish coat. On older lime-rich stucco, a softer mix works better than straight portland cement.

Synthetic stucco is usually called EIFS, short for Exterior Insulation and Finish System. It is a thin, flexible finish over foam board rather than a thick cement coat. Minnesota home inspectors note that EIFS is uncommon on Minnesota houses, and most local stucco is traditional cement stucco. A tap on the wall usually tells them apart: EIFS sounds hollow and feels softer.

Yes, if the existing stucco is sound, clean and well bonded. A new finish coat or acrylic recoat can go over it after cracks are repaired. If the wall has hidden moisture damage, recoating only hides it, which is why we recommend moisture testing first on newer homes.

Well-built stucco can last many decades; plenty of Minneapolis stucco from the 1920s is still on the wall. Lifespan depends far more on flashing, drainage and maintenance than on the stucco itself. Woodbury found that many late-1980s and 1990s stucco homes needed major repair within about 10 years because water got behind the stucco.

For a stucco home built since the late 1980s, many Minnesota inspectors recommend it. Probe testing reads the moisture in the sheathing through small holes at likely leak points and costs a few hundred dollars to around $1,000. The seller usually has to sign a release before holes are drilled.

Cement-based stucco should not be applied when temperatures are below about 40°F or frost is possible, according to the National Park Service. Some inspection, testing and interior-side work can happen in cold months, and emergency leaks can be protected temporarily. Most base coat and finish work is scheduled from spring through fall.

HomeAdvisor's 2026 figures put most stucco repairs between $599 and $2,661, with minor patches at $200 to $600. Repairs involving water damage run about $30 to $50 per square foot. We give a written price after seeing the wall.

Often, if the texture and color are matched in the finish coat. On a large, weathered wall a single patch can still read as newer, so a finish coat over the whole elevation is sometimes the better choice. We tell you which to expect at the estimate.

Usually because the cause was never fixed: a leak behind the wall, movement at a corner or opening, or a patch made with a mix that does not match the wall. We look for the cause before repairing the crack again.

That depends on your policy and the cause of the damage, and only your insurer can answer it. Many policies treat long-term leaks differently from sudden events. We can document what we find so you have it for any conversation with your insurer.

Fine hairline and map cracks are common as stucco cures and the house moves. They are usually cosmetic, but they can still hold water, so sealing them before a Minnesota winter is worthwhile. Wider or growing cracks deserve a closer look.

HomeGuide estimates $400 to $1,500 for crack repair on a 1,500 square foot home, and national guides list professional crack repair at about $8 to $20 per square foot. Cracks tied to foundation movement cost more. We price after seeing the cracks.

Caulk works in movement joints and around windows, but in the face of the wall it rarely matches the texture and can trap water. A flexible stucco patch or elastomeric filler with a matching finish is the better repair.

Most do not. Wide, stepped or growing cracks near the foundation, especially with sticking doors or windows, can point to settlement. In that case we recommend having the foundation checked before the stucco is repaired.

Structure Tech, a Minnesota inspection company, lists whole-house probe testing from $845 for homes up to 3,000 square feet and $545 for a single wall. HomeGuide puts inspections with moisture probes at $500 to $1,000 nationally.

It leaves small 3/16-inch holes at each test point. They are sealed with caulk matched to the stucco color and are usually visible only up close. The probes pass through the moisture barrier, which is why the holes are sealed deeply.

Minnesota stucco inspectors consider infrared inconclusive on its own. A cool spot on a scan does not prove water has reached the sheathing, and wet sheathing does not always show up. Probe readings measure the sheathing directly.

Stucco homes built from about the late 1980s on, especially those with windows lacking head flashing, roofs ending against walls without kickout flashing, decks attached through the stucco, or soil above the base of the wall. Woodbury found 67% of its stucco homes from that period had failed.

Yes, if the existing stucco is sound, clean and dry. Cracks and damaged areas are repaired first, then a new finish coat bonds to the old surface. If the wall has hidden moisture damage, a recoat just covers it up.

Paint costs less up front, around $1.50 to $4 per square foot nationally, but it is a film that can peel and trap moisture. A recoat, around $4 to $5 per square foot, adds a thin layer of colored stucco that wears with the wall. The right choice depends on the wall's condition and current coatings.

It fills and covers fine map cracks. Larger cracks must be repaired before the recoat, or they will telegraph through. Cracks that come from movement can return over time.

Prep and crack repair, curing, and the finish coat itself typically take several days to a couple of weeks depending on the size of the house and the weather. Rain and cold delay the work.

It is usually called EIFS, for Exterior Insulation and Finish System, or synthetic stucco. It is a thin acrylic finish over a mesh-reinforced base coat on foam board, rather than thick cement stucco.

Angi's 2026 figures put a small 10 square foot repair at $300 to $500 and professional repairs at about $30 to $50 per square foot. Woodpecker holes run about $250 to $450 each according to Fixr. Moisture damage behind the foam costs more.

It should not be. Cement stucco is rigid and heavy and does not bond or move the same way as EIFS, so the patch tends to crack and leak at its edges. EIFS needs foam, base coat, mesh and acrylic finish.

Minnesota home inspectors say EIFS is rare on Minnesota houses, and most residential stucco here is traditional cement stucco. It does appear on some homes and many commercial buildings.

Often because the patch was made with hard portland cement on a softer, lime-rich wall. The two materials move differently with temperature and moisture, so the patch cracks at its edges and lets water in. A compatible mix avoids that.

Many Minneapolis homes still have stucco from the 1910s through the 1930s, so well-maintained stucco can last a century. Keeping water off the wall and making compatible repairs matter more than the original installation date.

If the house is a local landmark or in one of the city's twelve local historic districts, exterior alterations go through heritage preservation review. Limited repair is usually a minor, staff-level review; material changes can need a hearing. We confirm before work starts.

Most original stucco can be repaired in sections. Full replacement is usually needed only when large areas have lost their bond or the lath behind has failed. A tap survey shows how much is sound.
