Where Can I Buy Weep Screed? An Expert Guide to Sourcing the Right Metal
Weep screed is the single most critical waterproofing component on your stucco home. Yet, if you walk into a generic hardware store, you will likely buy the wrong one. Because stucco systems vary by thickness (3-coat vs. 1-coat) and material (Galvanized vs. Vinyl), sourcing the correct profile is not as simple as buying lumber.
This guide breaks down where to find professional-grade lath accessories in Southern California, how to save money, and the logistical challenges of transporting them.
1. The "Big Box" Store Trap (Home Depot / Lowe's)
While convenient, major home improvement chains are rarely the best choice for stucco lath accessories. Here is why pros avoid them:
- Incorrect "Ground" Depth: Most box stores stock weep screed designed for "One-Coat" stucco (1/2" or 5/8" ground). If you use this on a traditional "Three-Coat" home (which requires a 7/8" ground), your wall will be too thick for the metal, leading to drainage failure.
- Limited Material: They often stock vinyl accessories. While vinyl is good for coastal areas, many homeowners prefer the rigidity of galvanized steel for straight lines.
- Damage Risk: The metal stock in these aisles is often bent, twisted, or damaged by customers, making it impossible to set a straight line on your foundation.

To get the correct material, you must visit a dedicated "Lath and Plaster" supply yard or a masonry yard (e.g., Hub, Westside, or local independent yards). They offer:
- Variety of Profiles: They stock the standard #7 Foundation Weep Screed in all grounds (1/2", 5/8", 7/8", and 1-3/8").
- Expert Knowledge: The counter staff understands local codes. If you tell them you are in Newport Beach, they will likely recommend a Vinyl or Zinc screed to prevent salt-air corrosion.
- Cost Savings: Believe it or not, specialty yards are often 30–50% cheaper than big box stores for metal products because they buy in massive bulk.
3. Know Your Specs Before You Go
Don't just ask for "weep screed." You need to know three things to get the right part:
The Buyer's Cheat Sheet
- The Ground (Depth): This is how far the metal sticks out from the wall.Existing older home? Usually 7/8".
Newer track home? Could be 1/2" or 5/8". Measure your existing stucco thickness first.
- The Flange (Height): The back vertical leg. Code usually requires a minimum 3.5-inch vertical attachment flange.
- The Material:Galvanized: Standard for inland areas.
Vinyl (PVC): Essential for coastal homes (no rust).
Zinc/Stainless: High-end, rust-proof metal options.
4. The Logistics Warning: "The 10-Foot Problem"
This is the most common mistake DIYers make. Weep screed (and all stucco trims) come in 10-foot lengths. They are rigid and cannot be folded.
⚠️ Transport Tip
Do not show up in a sedan. A 10-foot stick of metal will stick out of a standard SUV by 3-4 feet. You need a truck with a rack, or you must be prepared to flag the load safely. If you try to bend them to fit in the car, you ruin the screed.
5. Sourcing Hard-to-Find Profiles
If you are matching a specific historic profile (like a copper weep screed or an extended 6-inch flange for retrofitting), local yards can special order from manufacturers like Stockton Products or CEMCO.
Note on Matching: Always bring a physical photo and a measurement of your existing screed to the counter. "Eyeballing it" usually results in a return trip.
Conclusion: Don't Compromise the Foundation
Weep screed is the exit door for moisture in your walls. Buying a cheap, mismatched part from a general store to save a trip will cost you thousands in rot repair later. Go to the supply yard, buy the commercial-grade #7 screed, and ensure your home stays dry.

Frequently Asked Questions About Stucco
How much does stucco repair cost in Orange County and Los Angeles?+
Stucco repair typically ranges from $500 for minor crack patching to $5,000+ for full re-stucco of a single elevation. The exact cost depends on the damage type (hairline cracks, water damage, delamination, weep screed failure), the square footage involved, and whether the original three-coat or one-coat stucco system needs to be matched. Stucco Champions provides fixed-price written estimates after a free on-site assessment — no hourly billing, no surprise change orders. See our stucco repair cost guide for detailed pricing by repair type.
How long does stucco last in Southern California?+
Properly installed three-coat stucco lasts 50-80+ years in Southern California's climate. The most common failure points aren't the stucco itself — they're the supporting components: corroded weep screed, deteriorated building paper behind the stucco, and improperly sealed window flashing. Most "stucco failures" are actually moisture-intrusion failures that start at one of these points. Annual visual inspection catches problems before they spread, which is why we offer free weep screed assessments for homeowners in our service area.
Can I repair stucco myself, or do I need a contractor?+
Hairline cracks under 1/8 inch wide can be sealed with elastomeric caulk by a homeowner. Anything larger — pattern cracks, delamination (where stucco pulls away from the wall), water-damaged areas, or chimney/window leak repairs — requires a licensed contractor. Improper DIY repair on these is the #1 cause of repeat failures because the underlying cause (usually moisture) isn't addressed. California's CSLB requires a license for any stucco work over $500. We're a CSLB-licensed and insured contractor — see our contractor team for credentials.
How do I know if I need stucco repair vs. full re-stucco?+
If less than 30% of an elevation has visible damage, repair is the right call. If you see large areas of cracking, multiple zones of delamination, or the underlying paper and lath have rotted across an entire wall, full re-stucco of that elevation is more cost-effective long-term. Our free assessment includes a moisture survey and lath inspection so you get a defensible recommendation either way — not just a quote pushing whichever option costs more.
Do you offer warranties on stucco work?+
Yes. Stucco Champions provides a written 5-year workmanship warranty on all stucco repairs and a 10-year warranty on full re-stucco. We're a CSLB-licensed and insured contractor (license #1122006 — verifiable at cslb.ca.gov), which means our work is backed by California's contractor licensing board, not just our own promise. Request a free estimate to see the warranty terms in writing before you sign anything.
How long does a stucco repair take?+
Most patch repairs are completed in 1-2 days, including a 24-hour cure time before texture matching and color application. Full re-stucco of a single elevation runs 5-7 working days because each coat (scratch, brown, finish) needs to cure properly before the next is applied. We schedule around weather — California stucco needs daytime temperatures above 50°F with no rain forecast for at least 24 hours after each coat. Our crew shows up on time, every time.
