Stucco repair costs in San Antonio

Plastered walls go back a long way in San Antonio. At Mission Concepción, painters worked color into wet lime plaster on the outside and inside of the church, and those thick walls still stand about 250 years later. In January 2026, National Park Service craftspeople filled small cracks in the old plaster on the Espada Aqueduct to cut down on water leaks. A stucco house here faces the same water on a smaller scale.

The soil here works against you. The Blackland Prairie, with clay that swells when it's wet and shrinks when it dries, runs south as far as San Antonio and Bexar County, so a crack here isn't always the wall's own fault.

If you live in one of the city's historic districts, add a step. The Office of Historic Preservation requires a Certificate of Appropriateness for every exterior repair on a property with a historic overlay. That includes side and back walls nobody sees from the street. Some requests get a staff sign-off without a hearing; others go to a public hearing. Ask your contractor up front if they've worked under those rules, because starting without approval can bring a stop-work order.
