A weep screed is a metal flashing installed at the base of a stucco wall, just above the foundation. It has small openings that allow any moisture that gets behind the stucco to drain out instead of being trapped against the sheathing and framing. It is one of the most important — and most commonly damaged — components of a stucco system.
What Does Weep Screed Repair Cost?
| Repair Type | Cost Range |
|---|---|
| Localized repair (small section) | $500 – $1,000 |
| Partial replacement (one wall) | $1,000 – $2,000 |
| Full replacement (entire perimeter) | $2,000 – $3,000+ |
Costs vary based on accessibility, how much stucco needs to be removed and reapplied around the repair area, and whether water damage to the substrate needs to be addressed.
Signs Your Weep Screed Needs Repair
**Stucco touching the ground.** If soil, mulch, or concrete has been graded up to cover the weep screed, moisture cannot drain out. This is the most common issue — landscaping changes over the years bury the weep screed without the homeowner realizing the consequence.
**Staining or efflorescence at the base of walls.** White mineral deposits or dark staining at the bottom of stucco walls often indicates blocked drainage.
**Soft or spongy stucco near the foundation.** When the weep screed is blocked or missing, trapped moisture deteriorates the stucco, sheathing, and framing from the bottom up.
**Rust stains.** A corroded weep screed leaves rust streaks on the stucco surface.
**Pest entry.** Damaged or corroded weep screed openings can allow insects and rodents behind the stucco.
Why It Matters
A functioning weep screed is your stucco system's primary defense against trapped moisture at the base of the wall. Without proper drainage:
- Moisture rots the wood sheathing and framing
- Mold grows behind the stucco where you cannot see it
- The stucco delaminates from the substrate
- Repair costs escalate from a simple weep screed fix to full stucco remediation
Prevention
- Keep soil, mulch, and landscaping at least 2 inches below the weep screed
- Do not let concrete, pavers, or walkways cover the weep screed
- Inspect the base of your stucco walls annually and clear any debris from the weep openings
- Check for proper grading so water drains away from the foundation

What happens if the weep screed is covered by soil?
When soil or mulch covers the weep screed, moisture cannot drain from behind the stucco. This traps water against the sheathing and framing, leading to rot, mold, and eventual stucco failure. Keep soil at least 2 inches below the weep screed.
