Decking Supplies in Pontiac, IL

Composite decking is made from a blend of wood fibers and recycled plastics, so it resists rot, warping, and insect damage better than most natural woods and usually needs less maintenance. Traditional wood, like cedar or pressure-treated pine, offers a classic look, can be sanded and refinished, and often has a lower upfront cost. However, wood typically requires regular sealing or staining and more frequent upkeep. Your choice often comes down to desired appearance, budget, and how much maintenance you’re willing to do.

In a climate with hot summers, cold winters, and frequent freeze-thaw cycles, composite and PVC decking generally perform better than many natural woods because they’re less likely to crack, warp, or split. Pressure-treated lumber is also popular because it’s treated to resist moisture and decay, but it can still move or check over time. Hardwoods like ipe are very durable but may require more specialized installation and maintenance. It’s important to consider both moisture resistance and how the material handles expansion and contraction.

For Pontiac’s climate, prioritize materials with good moisture resistance, UV stability, and a proven track record in freeze-thaw conditions. Look for boards with a solid warranty, slip-resistant textures, and colors that won’t fade quickly in full sun. Also consider whether you prefer low-maintenance options like composite, or if you’re comfortable with the regular staining and sealing required for wood. Checking local building codes and load requirements will help you choose the correct board thickness and span rating.

Hidden fastener systems create a cleaner, screw-free surface and are commonly used with composite and PVC boards that have grooved edges. They can reduce the risk of surface splitting and help maintain consistent board spacing, but they may add to labor and material costs. Traditional deck screws are more visible but are often simpler to install and easier to remove if you need to replace a board. The best choice depends on your decking material, budget, and how important a seamless look is to you.

Composite decking blends wood fibers with plastic and feels more like wood underfoot, while PVC decking is all plastic and usually offers the highest resistance to moisture and staining. Capped composite boards have a protective shell around a composite core, giving you the look and feel of composite with extra stain and fade resistance. PVC is often lighter and cooler underfoot in full sun, but some people prefer the more natural look and texture of capped composite. Comparing warranties, slip resistance, and color options will help you decide which low-maintenance product fits your needs.

With composite and PVC decking, it’s crucial to follow the manufacturer’s spacing guidelines to allow for expansion and contraction in temperature swings. Use approved fasteners or hidden clip systems designed specifically for the product to avoid voiding warranties. Make sure the framing is properly flashed and ventilated so moisture doesn’t get trapped under the deck. Always pre-plan board layout, including staggering joints and accounting for any border or picture-frame designs you want to include.
