This guide is for anyone buying and installing Georgia-Pacific siding for a mid-to-large project. I'm a procurement manager, and I've been tracking orders for building materials for about six years. Over that time, I've learned that the gap between a well-budgeted project and a budget blowout is often a few small decisions made in the first 24 hours. Here’s the checklist I use to keep costs down without sacrificing quality.
We’re covering all 8 steps, from verifying the order specs to that final walk-around. Most people rush steps 3 and 6. Don’t. I’ll explain why.
1. Confirm the Specific Product & Its Code
You don’t just order "Georgia-Pacific siding." You order a specific product line—like GP Ply-Bead or GP DensGlass or Plytanium®—and you need the correct SKU. I once had an order of 1,200 panels where the warehouse picked the wrong product code because it looked similar in the catalog. It wasn't caught until the truck arrived on site.
Checklist item: Verify the exact product name, SKU, and thickness before the order is placed. Have a second person confirm the match against your spec sheet.
2. Source from Two (or Three) Verified Distributors
Our procurement policy requires quotes from a minimum of three vendors. For a $4,000 to $6,000 siding order, the price difference can be $500 or more simply based on which distributor you call. In Q2 2024, I compared quotes for a 1,500-sq-ft project using GP DensGlass. The difference between the highest and lowest quote was 14%. The lowest wasn’t the best—their shipping window was “3 to 6 weeks,” which was unacceptable.
Checklist item: Get quotes from at least two authorized GP distributors. Compare not just price, but delivery timeline and minimum order quantities.
3. Check the Delivery & Handling (Don’t Forget This)
This is the one most people skip. The “free delivery” or low shipping cost on a large siding order often comes with a catch—it might be curbside only, or the truck doesn’t have a lift gate, or they drop it on an uncovered trailer in the rain. After tracking 60+ orders, I found that 23% of our budget overruns came from handling and damage issues during delivery.
Checklist item: Specifically ask: “What is the delivery method? Curbside or tailgate? Will the material be covered? Can we request a covered trailer?”
4. Review the Installation Specifications (Don’t Assume)
Every builder thinks they know how to install siding. But GP panels require specific nailing patterns and spacing for—especially with engineered wood or fiberglass mat facers. I didn't fully understand the value of this until a contractor re-did a 200-sq-ft section because the spacing was wrong. That cost us $1,200 in redo labor and materials.
Checklist item: Make sure the installation crew has a copy of the GP installation guide. Check that they are using the specified fasteners (e.g., hot-dipped galvanized or stainless steel nails).
5. Plan for Waste (But Be Realistic)
A standard waste allowance is 5-10%. That works if your walls are simple rectangles. For a project with lots of windows, corners, or gables, you should go to 15%. I’ve found that using a 10% waste factor on a complex facade led to a shortage of 30 panels. We had to order a second batch, paying a $250 rush fee.
Checklist item: Calculate waste factor based on the actual blueprint, not a guess. Add 15% for complex layouts. It’s cheaper to return unopened bundles than to pay a rush fee.
6. Unload & Stage the Material Properly (The Most Common Mistake)
The truck arrives, everyone is in a hurry, and the panels get stacked directly on the ground or leaned against a wall. That’s how edge damage happens. GP panels, especially the engineered wood products, are durable but not invincible. Moisture wicking from ground contact can cause swelling in the edges.
Checklist item: Unload onto a flat, dry surface. Use 4x4 timbers to keep panels off the ground. Stack them flat, and cover them with a tarp if rain is within 24 hours.
7. Conduct a Quality Check at Delivery
When the truck shows up, don’t just sign the receipt. Have the checklist ready. Look for:
- Edge damage: Are the edges dented or crushed?
- Warping: Are any panels bowed?
- Finish defects: Is the coating chipped or peeling?
Checklist item: Reject any damaged panels immediately. Take photos. This is your window for a replacement without a charge.
8. Final Walk-Around After Installation
This step isn’t just for the homeowner. If you’re the contractor or the property manager, do a slow walk-around 48 hours after installation. Look for:
- Gaps between panels (spec calls for 1/8-inch spacing).
- Fasteners that are over-driven (cracks in the panel face).
- Moisture at joints (if it rained).
One project I managed had a subtle moisture issue because the flashing wasn’t installed correctly. Caught it early. Cost us $400 to fix. If we’d waited until the next month, it would have been $5,000.
A Few Things to Watch Out For
- Shipping damage claims: Don’t sign for a delivery with visible damage. You can’t claim it later.
- Expiration of quotes: Most GP distributor quotes last 15-30 days. If your project is delayed, get a re-quote.
- Color matching: If you’re ordering pre-finished panels, make sure the batch number matches. Even slight differences between production runs can be visible.
Take this checklist with a grain of salt: it’s based on my experience with mid-size commercial projects. If you’re building a single house or dealing with specialty materials, some steps might not apply. But for a standard job, this should save you from the biggest pitfalls.
