You can estimate it will cost $6-$9 per square foot to add stucco to your house. The bigger the wall, the higher the cost.
Material and stucco costs will depend on the type you use (traditional vs. engineered). Expect to pay around $2,000 on average to replace or install new stucco on one side of an average-sized garage's exterior.
Stucco siding cost factors
The cost to stucco a house depends on the type of stucco used (engineered, synthetic or traditional stucco), the number of square feet of siding and whether old siding needs to be repaired or removed.
Traditional stucco vs. engineered stucco
The material costs for stucco siding will depend on if you're using traditional or engineered stucco, also known as exterior insulation finishing system (EIFS). The average cost for traditional, cement-based stucco is $0.05-$0.10 per square foot, compared to $0.25-$0.50 per square foot for EIFS (just for materials, not installation or labor costs).
Stucco has been used in architecture for centuries and is prized for its durability, heat resistance, and beauty. Traditional stucco is a mix of cement, sand-lime and water and is quite different from the synthetic stucco products on the market, says a Thumbtack pro and stucco specialist in Elk River, Minnesota. Both are used for exterior walls and sidings on houses, while plaster is used indoors. The application of high-end traditional stucco requires a skilled craftsman and generally costs more upfront, but it will last longer and protect the house in a way that saves money in the long run. Traditional stucco is heavy and handles wet weather well.
EIFS has a much thinner and smoother final texture and is usually applied over a foam-based product. Engineered stucco is also more likely to crack but is still energy-efficient and lends itself to more complex designs.
Stucco repair cost
Stucco repair costs are impacted by the square foot size of the area in need of repair. Most companies will have a base rate that means a basic fist-sized stucco repair might cost nearly the same as a window-sized repair.For stucco companies, it's not just the material and the size of the repair — it's also the company's business overhead and labor costs. For this reason, many companies will have a flat rate or project cost instead of charging by the square foot.
Here are some examples of average costs for stucco repairs and installation from a Thumbtack pro in Minnesota:
Window-sized or smaller stucco repair: $500
Stucco repair around two windows and two doors: $1,000
Stucco replacement on one exterior wall of a garage: $2,000
New stucco installation on three walls of a 12x12 home addition: $4,000-$5,000
The final project required special matching to ensure the three new exterior walls match the home's existing stucco.
