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.

The least expensive way to build a pool deck is with concrete deck blocks, pressure-treated lumber, and the appropriate hardware for hanging joists and securing deck boards. With these basic yet durable deck materials, you'll have a pool deck that's built to last without the high price tag. You should also stain or seal the deck to protect it against the elements.

Deck boards should be spaced no more than three-eighths of an inch apart. This is enough space to allow water and small debris to pass through without collecting on the surface, but not enough to create a tripping hazard. Certain materials, like pressure-treated wood, shrink over time, so they may need less space at installation.

Both aluminum and composite decking materials are environmentally friendly, with aluminum decking coming in as the most eco-friendly option. 

Though composite decking helps remove plastics from landfills, recycles wood, and lasts longer than traditional wood decks, it’s not recyclable and only lasts for 25 to 30 years on average. Aluminum can last well over 30 years and is almost always recyclable.
