The best way to clean your decking is to clear debris from the gaps between the boards, sweep the surface, rinse it, apply cleaner, rinse again, and let it dry fully. A homemade deck cleaner made of two gallons of warm water and 1/2 cup vinegar is a simple cleaning solution for both wood and composite decking. You can sprinkle baking soda on any spots with mold or mildew, then scrub the area and rinse clean. 

Yes, it is possible to build a small, basic deck for $5,000, particularly if you use less expensive materials and a simple design. To stay within this budget, consider a size under 10x12 feet and use affordable materials like pressure-treated wood or cedar. While the general cost for deck building ranges from $4,350 to $12,560, with an average around $8,200, some projects can be completed for as little as $4,350. You can also save on labor costs by doing the work yourself, but be aware that mistakes could end up costing more than hiring a professional. A contractor may have a higher upfront cost, but they can ensure a safe, stable deck that will last.

The overhang, or nosing, of deck steps is another area that will be covered in building code requirements. The noses on your deck steps should have a minimum overhang of ¾ inch. For safety, usability, and code compliance, the nosing of deck steps should not extend past 1¼ inches.

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.
