The decision to repair or replace stucco depends on the extent of the damage. For minor issues like small cracks, holes, dirt, stains, or discoloration, a repair is typically sufficient and more cost-effective. These issues can often be resolved with a simple repair, a deep clean, and possibly a new coat of paint. However, for more significant problems such as large cracks, peeling, mold, algae, or structural water damage, a replacement might be necessary. In these cases, it is best to call a professional stucco contractor for an inspection. An expert can assess the severity of the damage, determine if there are deeper issues, and advise whether a repair is adequate or if replacing a section or an entire wall is the more cost-effective, long-term solution.

Stucco will dry in two to three days, but you should wait one to two months to allow it to cure fully before you paint it. The curing process is slow, but leaving the material exposed to air and natural moisture will help it reach its maximum strength. If you live in a hot, arid climate, wait a month before painting. Wait two months before painting if you live in a more moderate or wet climate.

The best adhesive that works on stucco is usually a product specified for use on stucco or concrete surfaces. The adhesive will need to be strong to grip the stucco, but should also wipe away clean when used in a temporary application. You can also consider using super glue or hot glue on stucco.

If your windows are losing efficiency from wearing out or experiencing leaks on rainy days, it may be time to consider replacing them. Window replacement costs run between $180 and $410 per window but may be on the higher end for homes with stucco siding since stucco will likely require more time and special tools for replacement.
