The short answer
Repair the stucco when the damage is contained and the framing and weather-resistive barrier behind it are dry. Rebuild the wall section when moisture has reached the sheathing. Re-stucco the whole home when multiple walls are failing at once or the original barrier has reached end of life. A moisture reading, not the surface, decides which one you are looking at.
When a repair is the right call
If the cracking or damage is localized, the sheathing reads dry, and the weather-resistive barrier behind the stucco is still intact, a spot repair is correct. We seal and color-match the patch to the existing wall. On heavier textures the repair disappears; on smooth finishes it can be visible up close, which is worth knowing before you decide. This is the most common and least expensive path when the wall behind the surface is sound.
When to rebuild a wall section
Once moisture reaches the framing, patching over it just buries the problem. The right scope is to remove the affected section, replace the damaged framing and sheathing, install a properly lapped weather-resistive barrier with correct flashing (including kick-out flashing where the roof meets the wall), and re-stucco. This costs more than a patch but it closes the water path, which a patch never does. If you are seeing repeat cracking, our guide on why stucco cracks explains what that pattern usually means.
When to re-stucco the whole home
When multiple walls read wet, when patches keep failing, or when the original weather-resistive barrier has simply reached end of life, a full re-stucco is usually the more economical decision. This is common on 1990s and 2000s builds around Snohomish County and on older stucco homes across North Seattle. One correct rebuild beats years of chasing the same water around the house.
The cost angle
Repair is cheaper up front; replacement is often cheaper over the life of the wall when the assembly is failing.

Repair vs. replace, answered.
Can stucco be repaired without redoing the whole wall?
Often, yes. If the framing and weather-resistive barrier behind the stucco are dry and intact, a spot patch and color match is the right repair. Once moisture has reached the sheathing, the better answer is to remove the affected wall section and rebuild the assembly so the failure path is closed.
How do I know if my stucco is beyond repair?
The tell is not the surface, it is what is behind it. Widespread high moisture readings, soft or spongy sheathing, cracking that keeps returning after patches, and staining that spreads all point past a cosmetic repair. When multiple walls read wet at once, a full re-stucco is usually more economical than chasing patches.
Is it cheaper to repair or replace stucco?
Repair is cheaper up front when the damage is contained and the wall behind it is sound. Replacement is cheaper over time when the assembly is failing, because repeated patches on a wall that keeps taking on water cost more than one correct rebuild.
How long does stucco last before it needs replacing?
A correctly built three-coat stucco assembly can last decades. What usually fails first in the Pacific Northwest is not the stucco itself but the weather-resistive barrier and flashing behind it, which is why many 1990s and 2000s homes reach end of life on the assembly even when the surface still looks acceptable.
