Most building codes require that railing spindles (also known as balusters) on decks or stairs be spaced no more than four inches apart. This safety standard is often called the '4-inch sphere rule,' which means a sphere with a 4-inch diameter should not be able to pass through the opening between balusters. This rule is in place to prevent small children and pets from slipping through the railing. For the same reason, the space between the bottom rail and the deck or floor surface 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 essential to check your local building codes to ensure compliance before starting your project.

Staining and sealing the underside of a deck creates a moisture barrier but traps water in the boards, quickly leading to rot. No matter how well you seal the above deck, water still gets through via nails and screw heads on the surface. Allow this water to flow naturally under the deck, where it is routed through the drainage system.

The life expectancy of deck boards varies widely based on the material, climate, and maintenance. Untreated wood boards typically last 10 to 30 years with proper care, while pressure-treated boards can last up to 50 years. Hardwoods generally outlast softwoods. Composite boards also tend to last longer than natural wood. Environmental factors like arid or humid climates can shorten a deck's lifespan. To extend the life of wood decking, it's important to consistently clean and seal it to protect against moisture, UV light, and insects.

When installing deck boards, screws are generally a better option than nails. Screws offer superior holding strength over time, keeping the boards securely in place. In contrast, nails are more likely to pop out, which can create a tripping hazard. While you can use either, we recommend using 3-inch galvanized deck screws. To minimize the risk of cracking the wood, it's a good practice to drill small pilot holes before driving the screws into the deck joists.
