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.

If you want to make a deck cleaner from products already in your home, there are various options. The most common is to use a gentle blend of 1 gallon of warm water and 2 tablespoons of ammonia-free dish soap. You can also mix water with distilled vinegar. Sprinkling on some baking soda can help to remove mold and mildew. You can add oxygen bleach (but never damaging chlorine bleach) to the water and ammonia-free dish soap solution for something a bit stronger. 

The best way to sand a deck is by cleaning it, sanding the boards and stairs with 60- or 80-grit sandpaper, and sanding the railings and posts with 80-grit sandpaper. You should sand in the direction of the wood grain to avoid damaging the timber. When sanding your deck, use medium pressure and aim for an even sand. Pressing too hard with a sander can damage decks, as most are softwoods.

Deck skirting shouldn’t touch the ground, especially if you have a wood deck, which is vulnerable to moisture. Ideally, you should leave at least 3/4 of an inch of space between the deck skirting and the ground for more ventilation. Pros also recommend that you incorporate about 1 square foot of space for ventilation for the underside of the deck to every 150 square feet of decking. Proper ventilation prevents mold growth and rot that can damage your deck.
