Yes, Ipe is more expensive than Trex decking—both in terms of materials and installation (plus, Ipe trees are endangered). On average, Ipe decking costs $10 to $25 per square foot, while Trex decking costs $5 to $12 per square foot. Because Ipe is harder to work with, the price of installation is higher, too. For Ipe decking, you’ll pay between $20 and $45 per square foot for labor. However, with Trex decking, the labor costs range from $8 to $22 per square foot.

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.

Most building codes list a minimum width of 36 inches and a maximum height of 7¾ inches. However, for the most comfort and spaciousness, you’ll want to aim for a width of at least 48 inches and a height of 7 inches. Again, it’s always a good idea to base your numbers off steps that you already use comfortably.
