Weep Screed Repair — OC & LA
Mold. Rot. Termites. It Starts at the Weep Screed.
A failed weep screed traps water inside your walls. That moisture breeds black mold, rots the wood behind the stucco, and creates entry points for termites and carpenter ants. We cut out the damage and rebuild the base of your wall to code.
The Most-Neglected Part of Your Stucco System
It's a Drain, Not a Trim Piece.
The weep screed is an L-shaped metal flashing that runs along the bottom edge of every stucco wall. It does two jobs that the rest of the system depends on: it creates a clean stopping point so the stucco never touches the ground, and it gives any water that finds its way behind the stucco — through a hairline crack, a leaky window, or a sprinkler hitting the wall all afternoon — a path to drain back out to the exterior.
When that drain gets buried by landscaping, clogged with paint, or rusts through from decades of moisture exposure, water that enters the wall system has nowhere to go but down into the sill plate and the framing behind it. It's the quietest and most expensive failure in a stucco system — because by the time you notice it from outside, the damage inside the wall has usually been accumulating for years.
Weep screed is required on every stucco installation by California Residential Code R703.6.2.1 and IRC R703.7.5 — minimum 4" clearance above earth, 2" above paved surfaces.

Warning Signs
5 Signs Your Weep Screed Is Failing.
If you see any of these along the base of an exterior stucco wall, the weep screed is the first place we look during an assessment.
White chalky stains at the base
Efflorescence — mineral deposits left behind when water is chronically trapped inside the wall and seeps out through the stucco. By the time you see it, the framing behind is already wet.
Stucco is soft, bulging, or cracked near the ground
The bottom 12 inches of a stucco wall bears the brunt of sprinkler splash-back, soil contact, and groundwater. Bulging or spongy stucco means the wire lath has rusted and the substrate is compromised.
The weep screed is buried by soil, mulch, or new hardscape
Code requires 4" clearance above earth and 2" above paving. If landscaping was added later and buried the screed, the drainage path is sealed shut — water has nowhere to go but into your framing.
Visible rust or a gap where the screed should be
Original galvanized weep screeds eventually corrode through after decades of exposure. On older homes (pre-1960s or cheap builds), a proper weep screed was never installed in the first place.
Termites, carpenter ants, or rotted baseboards inside
Persistent moisture at the base of an exterior wall creates the exact conditions that attract wood-destroying pests. If you're seeing pest damage or soft flooring near an exterior wall, the weep screed is the first place to look.
What's Actually at Stake
A Failed Weep Screed Doesn't Leak — It Rots.
When the drain at the bottom of the wall stops working, water doesn't pour out in a dramatic stream. It wicks quietly into the sill plate, soaks the bottom few feet of the studs, feeds mold on the back side of the sheathing, and attracts termites and carpenter ants. All of this happens behind a wall that looks fine from the outside.
By the time you see bulging stucco, efflorescence, or soft flooring inside, the framing behind the wall has usually been wet for years. Insurance almost never covers this — they call it “long-term maintenance failure.” The only real fix is to cut it out, dry it out, and rebuild the base of the wall properly.
How We Do It
Six Steps to a Watertight, Code-Compliant Base.
Full-Base Inspection
We walk every exterior wall and check clearances, corrosion, soil contact, and any visible damage. Where the screed is buried, we probe to find out what's actually down there. You get a photo report before any work starts.
Controlled Cut-Back
We cut away the bottom 6–12 inches of stucco along the affected wall in a clean horizontal line. This gives us full access to the old screed, the sill plate, and the wire lath without disturbing the rest of the wall.
Substrate Check
Once the old screed is out, we inspect the sill plate, sheathing, and any exposed framing and show you exactly what we're looking at. Building paper repair is included if that's part of your quoted scope. If the framing needs repair, we quote that separately before any work starts — no surprise change orders on the final invoice.
New Code-Compliant Screed
We install a new galvanized or vinyl weep screed properly flashed into the new building paper, with full 4" soil clearance (or 2" above paving) restored — the minimums required by California Residential Code R703.6.2.1 and IRC R703.7.5. This is the step most contractors skip — and why their repairs fail within a season.
One-Coat Stucco Rebuild
We install new wire lath tied into the framing, then rebuild the cut-back zone with a fiber-reinforced one-coat stucco system. The new section is floated and textured to blend with the surrounding wall.
Drainage & Clearance Check
Before we leave, we verify clearances, confirm the weep holes are open, and walk you through what to watch for going forward. If landscaping needs to be pulled back, we tell you exactly how much and where.

Common Questions
Weep Screed Repair FAQs
What is a weep screed and why does it matter?+
A weep screed is an L-shaped metal (or vinyl) flashing installed at the base of a stucco wall. It does two critical jobs: it creates a clean stopping point for the stucco so it doesn't touch the ground, and it gives any water that gets behind the stucco — through hairline cracks, window leaks, or from above — a path to drain back out to the exterior instead of traveling down into the sill plate and framing. Without a functioning weep screed, water that enters the wall system has nowhere to go but into your structure.
Is a weep screed required by building code?+
Yes. California Residential Code R703.6.2.1 (and the IRC R703.7.5 it's based on) has required a weep screed on all stucco installations since the 1960s, with minimum 4" clearance above earth and 2" above paved surfaces. If your home was built after the 1960s and the weep screed is missing, corroded through, or buried by landscaping, the wall system isn't code-compliant anymore and you're running on borrowed time.
Can I just dig the landscaping away from the base of my wall?+
Sometimes — but only if the screed itself is still intact. Pulling back the soil restores the clearance and the drainage path, which stops future damage. But if the screed has already rusted through from years of being buried, pulling the dirt back won't fix the damage that's already happened inside the wall. The only way to know for sure is a proper inspection.
How do I know if the framing behind my weep screed is damaged?+
Classic tells: soft or bouncy flooring along an exterior wall, baseboard discoloration or warping, chronic pest issues near the base of an exterior wall, efflorescence (white chalky stains) on the lower stucco, or visible bulging at the bottom of the wall. We confirm with a moisture meter and by physically opening up a small test area — it's a 20-minute job during the free assessment and it tells us exactly what we're dealing with.
How much does weep screed repair cost?+
Weep screed repair is priced by linear foot of affected wall plus any substrate repair needed behind the screed. A clean run with intact framing is dramatically cheaper than a section where the sill plate is rotted and the sheathing needs replacement. Every quote is fixed-price after a free on-site assessment, and we tell you up front whether it's a small localized fix or a bigger rebuild before you commit to anything.
Will the new stucco section blend with the rest of my wall?+
Yes. We cut back in clean horizontal lines and finish the new section with the same sand or lace texture as the existing wall. If the new zone is isolated on its own wall plane, the transition blends well. If the existing stucco is badly weathered or discolored, we'll walk you through options — from blending with a clean seam to painting the full wall plane for a uniform look.
How long does a weep screed repair take?+
A clean 20-foot run with no substrate damage can be done in 2–3 working days from cut-back to final finish. Longer runs, rotted framing, or repairs that require coordinating with a pest inspection or a plumber can stretch to a week or more. We give you a realistic timeline before the work starts, not after.
