Most building codes require that spindles or balusters on deck and stair railings be spaced no more than four inches apart. This safety standard, often called the '4-inch sphere rule,' is designed to prevent small children or pets from slipping through the railing. A good way to visualize this is that a 4-inch sphere should not be able to pass between two spindles. For the same safety reason, the space between the bottom rail and the deck floor should also be no more than four inches. As a general guideline, professionals often install three balusters per foot of railing. However, since specific requirements can vary by location, it is crucial to check your local building codes to ensure compliance before starting your project.

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.

Cold temperatures can make your deck boards contract. If they don’t contract evenly, they can put pressure on the deck screws and cause them to pop out, making a noticeable sound. Winterizing your deck can help prevent this from happening.

Be careful when choosing a product to help you remove ice from your wood deck. Never use sand, gravel, or salt, since these items can damage and scratch the wood. Instead, look for chemical de-icers that are marked as safe for wood decks or use hot water to melt snow and ice.
