Stucco Repair in Minnetonka, MN

Many stucco repair projects in Minnetonka start with a question, not a crack: is this house safe to buy, or ready to sell? That makes sense in a city where 71.6% of homes are owner-occupied and the median owner-occupied value is $475,800, according to Census estimates for 2020 to 2024. When a stucco home changes hands at that level, nobody wants to learn about wet sheathing after closing.

Why looking at the wall is not enough

Minnesota's stucco moisture problems began at the end of the 1980s, and Twin Cities home inspector Reuben Saltzman has written that affected houses "always look fine," with usually no visible evidence of hidden damage. Clean, uncracked stucco can sit over soft or rotted sheathing. That is why we do not judge a Minnetonka wall by its face. We drill pairs of small holes at the spots where water tends to get in, such as below window corners, where a roof line meets a wall, and beside deck ledgers, then read the moisture in the sheathing behind.

Where Minnetonka fits in the story

Minnetonka grew in waves. The population roughly doubled between 1950 and 1960, from 11,896 to 25,037, and kept climbing to 48,370 by 1990. Many parts of the city stayed farms and horse pasture until the 1960s, and filled in afterward. That means the city holds a mix: postwar ramblers, homes from the 1970s, and homes from the 1980s, when the city added nearly 10,000 residents (from 38,683 in 1980 to 48,370 in 1990), and the 1990s, the same years when Minnesota stucco homes were failing at high rates elsewhere in the metro. If your home falls in that later window, testing is the first step we recommend before any cosmetic work.

What a test visit looks like

• We walk the exterior and mark probe locations based on the house's design: windows, roof-wall intersections, decks and spots where soil or a patio sits close to the stucco.
• Each probe pair is drilled small, read with a meter, and probed for firmness of the sheathing.
• Holes are sealed with color-matched sealant when we finish.
• You get a written summary of readings by location, with photos, that you can share with a buyer, a seller or your own agent.
• Testing waits for dry weather; readings taken during or right after rain are not reliable.

When the readings come back high

A high reading tells you where to look, not how big the problem is. The only way to size it is to open the wall in that area. We cut back the stucco, look at the sheathing and framing, and then give you a written scope for repair: replacing damaged sheathing, adding a proper weather-resistive barrier and flashing, and rebuilding the stucco in layers. Minnesota's re-siding rules require a building permit for this kind of work, plus inspection of the barrier and flashing, and replacement of any rotted sheathing or framing found once the siding is off. We pull what the city requires before we start.

Testing and selling

If you plan to list, test early. Repairs found in the spring can be done before the market heats up, rather than negotiated in a hurry with a buyer's inspector holding the report. If you are buying, the seller has to give permission for holes to be drilled, so raise it with your agent when the purchase agreement is written.
