Pressure-treated wood contains preservatives that give the material internal protection from rot and pests. Untreated lumber won’t last more than a few years unless you choose a more expensive wood, like cedar, that naturally stands up well to moisture. Composite decking can outlast wood but is more expensive and doesn’t look as natural. Keep in mind that you’ll need to seal any exterior wood product to protect it from the elements and other forms of external damage.

The proper and most comfortable height for a deck stair riser, also called a step, is between four and seven inches. A height of seven inches is often considered ideal for a strain-free step that minimizes the risk of trips and falls. While it is possible to have risers up to 12 inches, this height can be challenging for children, pets, or individuals with mobility issues. For optimal safety and comfort, pair a seven-inch riser with a tread depth (or run) of at least 10 to 12 inches. Always check your local building codes, as they may have specific requirements that differ from these general recommendations.

The choice between Trex, a brand of composite decking, and PVC decking depends on your priorities regarding budget, appearance, and environmental impact. Both materials are durable and resistant to moisture and insects. Trex is often considered more eco-friendly because it contains recycled wood and plastic and is 25% recyclable, while PVC is fully synthetic and harder to recycle. Aesthetically, Trex is designed to look more like real wood, whereas PVC often has a glossier, more plastic-like finish. In terms of cost, Trex is typically less expensive than PVC.

If you have wood decking, there are several common deck problems that you might encounter. For example, your natural wood boards may fade over time due to things like sunlight, weather, and debris. On top of that, some types of wood decking can rot, grow mold, and attract destructive pests—including termites, carpenter ants, and woodpeckers.
