4 Best Practices for Beautiful Siding Installation

Professionals know it’s not only the quality of the product that determines how polished a home’s siding looks, but also how well it is installed.

While having on-site experience can develop the skills for top-notch installation, sometimes even the most experienced builders make mistakes. Here are four tips to ensure your Grayne and Foundry siding projects are beautiful every time.

1. Use the Right Tools
Before you begin the installation process, it’s essential to be equipped with the right tools. Accidentally using the wrong tools can have consequences.

To cut the siding, use either a vinyl siding blade or a fine-toothed blade. If using a fine-toothed blade, be sure to install the blade in reverse for the best cuts.

Other tools to include on your checklist:
• Utility knife
• Caulking gun (to seal J-channel)
• Vinyl siding snips (to cut or trim siding panels)
• Siding removal tool
• Snap lock punch (to cut snap lock tabs and allow cut panels to be snapped into utility trim)
• Nail hole slot punch (to add nail holes if a panel must be face nailed)
• Trim nail punch (to add nailing holes if a panel must be face nailed)

2. Start with a Smooth Surface
If the surface beneath the siding is uneven, even the best siding installation may be compromised. Take appropriate precautions to ensure a smooth, continuous surface.

For new construction, avoid using green lumber as the underlayment, as it typically has high levels of moisture. As the wood dries, it will shrink, leading to cracking and warping. These flaws in the wood can make the siding look uneven and poorly installed.

If you are re-siding a building, furring or complete removal of uneven original siding may be required to create a smooth surface. While this process may seem like a nuisance, it will help to ensure straight, stable replacement siding.

3. Plan for Expansion and Contraction
To accommodate expansion, see siding manufacturers’ guidelines, as many panels install differently.

Always leave a minimum of 1/8″ gap at the nailing hem to accommodate changes from temperature shifts. If you’re installing siding in temperatures of 75 degrees F or higher, lessen the clearance slightly to at least a 1/16″.

4. Apply Panels Correctly
One of the most common mistakes installers make when applying panels is driving the head of the fastener tightly against the nail hem. Allow approximately 1/32″ (roughly the thickness of a dime) clearance between the fastener head and the siding nail hem.

During installation, avoid face-nailing or stapling through siding. Face-nailing can not only cause ripples in the siding, but also prevents proper expansion and contraction.

When installing a siding panel, push up from the bottom until the lock engages, then let the panel relax down against the ledge of the previously installed panel. Without stretching the panel, reach up and fasten it into place. Again, be wary of tightness—the panels should not be under tension or compression when they are fastened. Once fastened, allow the butt edge to rest on the top edge of the course below.
