When sourced responsibly, the most sustainable wood decking options are timber trees like redwood, pine, Douglas fir, Nootka cypress, and Western red cedar. These tree species are fast-growing with low carbon emissions. Plus, most timber woods make durable deck materials because of their resistance to rot and decay over time. 

The problems with composite decking include a high rate of expansion and contraction from temperature swings. This characteristic can cause boards to split, delaminate, or peel. In addition, significant movement can cause shrinking, warping, twisting, and bending. For this reason, you should minimize moisture and ensure proper airflow below your deck.

The best material for your deck depends on several factors, including your budget, location, aesthetic preferences, and the level of maintenance you’re willing to do. Wood decking, like redwood, ipe, cedar, and pine, lasts the longest, but it’s more expensive and requires more upkeep than composite and synthetic decking.

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.
