Deck Cleaning 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.

Staining and sealing the underside of a deck creates a moisture barrier but traps water in the boards, quickly leading to rot. No matter how well you seal the above deck, water still gets through via nails and screw heads on the surface. Allow this water to flow naturally under the deck, where it is routed through the drainage system.

In the majority of cases, you don’t need regulatory permission or permits to remove decking components and materials. However, the exception is if you live in or near a wildlife conservation area, which could require permits and consent prior to beginning the demolition. Check with a local regulatory agency for more information.

As with patios, there are many types of deck choices to choose from to add personalization to your home. Some common deck options include:

  • Attached decks are anchored to the home and include simple ground-level options or multi-level structures with stairways and separate landings. 

  • Detached island decks are not attached to the home; they’re a freestanding structure in the yard. 

  • Wraparound decks connect the back of the house with at least one other side and often are built with railings for safety. 

  • Multi-level decks connect your deck through varying levels of elevation, featuring landings that are attached to stairs.

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.
