The average cost of stucco siding is $5,400, ranging from $2,200 to $8,840. Stucco is worth the investment, provided you have the work done by a professional. Not only is stucco an attractive and durable siding material that boosts your home’s curb appeal, but it’s also more energy-efficient than most other siding options, it’s fire-resistant, water-resistant, and more affordable to repair down the road.

The average cost to repair stucco is about $1,600, with projects ranging from $250 for minor fixes to $6,700 for extensive work. The price is often calculated per square foot, typically costing between $60 and $120. Some professionals may charge an hourly rate of $40 to $50. The final cost depends on the extent of the damage, the type of stucco, your home's location, and whether there is underlying damage that also needs to be addressed.

Costs for specific repairs vary:

• Cracks: $8–$20 per square foot

• Holes: $250–$450 per hole

• Water damage: $30–$50 per square foot

• Chimney repair: $60–$120 per square foot

• Recoating: $4–$5 per square foot

While you may be able to patch small cracks yourself, it is recommended to call a professional for major repairs to ensure the job is done correctly.

Cracks in the chimney can be very serious, depending on their location and size. Even small cracks can become serious over time if left unrepaired. Cracks allow heat and moisture to deteriorate your chimney and harmful carbon monoxide gas to seep into your home. Small cracks can often be caulked, while large cracked sections may require full replacement.

Failing to repair damaged stucco can lead to significant problems. Cracks can grow and deepen, allowing water and moisture to get behind the stucco. This moisture intrusion can cause water damage, structural issues, and mold or mildew growth. Delaying repairs will likely cost more in the long run as the damage worsens, so it's best to repair your stucco as soon as you notice any signs of damage, such as cracks, holes, or discoloration.
