For a 12x20-foot (240-square-foot) deck, you can expect to pay between $7,200 and $14,400. This cost is based on a general price of $30 to $60 per square foot. The final price will depend on factors such as the decking material, design complexity, deck type, location, and local labor costs. Keep in mind that add-ons will increase the total; for example, adding an under-deck drainage system to a deck of this size could cost an additional $7,700.

Constant exposure to inclement weather conditions can damage your deck, causing it to fade, warp, or crack over time. Regular maintenance keeps it looking and performing its best. That means giving it a good cleaning and applying a quality sealant or wood treatment to help defend against moisture, sun damage, and everyday wear.

Pressure-treated decking may be worth it if you want a natural, insect- and rot-resistant decking material that will last for decades with proper maintenance. As such, it’s a much better option than untreated pine. Alternative wood decking materials like cedar and redwood tend to be less durable and more expensive. Some homeowners prefer composite decking, which is a low-maintenance alternative to wood but is also more costly.

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.
