Deck Maintenance FAQs, answered by experts

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.

Yes, an elevated deck can increase a home's resale value. Homeowners can expect a 65% return on investment from the cost of a second-story deck installation. For example, if you spend $5,000 to install a second-story deck, that deck will add $3,250 to the value of your home.

Typically, most residential wooden decks are designed to support approximately 40 pounds per square foot, including the deck’s weight and any items placed on it. While this is fine for typical use, it is usually not enough to hold the weight of a hot tub filled with water and people. To safely support a hot tub, your wood deck will likely require reinforcement. Therefore, it’s best to have a contractor or a structural engineer assess it before hot tub installation.

Composite decking might cost more upfront, but it delivers value in terms of durability. Unlike wood, composite material resists common deck problems such as rotting, fading, warping, and all the other things you don’t want a deck to do. The extra processes lead to a higher price tag, but you’ll save big in maintenance costs down the road.

There are ways to clean your deck to help maintain a clean appearance. You can easily remove surface-level dirt and grime by wetting your deck with a hose and doing a quick scrub with store-bought deck cleaner monthly. 

However, investing in professional deck cleaning services near you at least twice a year is worth it. This service saves you time and ensures that your deck will avoid accidentally becoming scratched by blasting the pressure washer at the wrong angle.
