Deck Cleaning FAQs, answered by experts

Before installing a deck, you must build a base for the deck to rest upon, often made of compacted soil or gravel. While gravel is an optional material, it helps with drainage. Some contractors also recommend installing a weed control membrane, which helps provide a solid foundation for the frame. In the case of an elevated deck, a pro will often lay down a concrete slab as a foundation. 

Materials for a second-story deck must be weather- and rot-resistant, though the specific choices will largely be determined by your budget and style preference. Pressure-treated wood is on the lower end of the price scale, but it can be customized and stained the way you like it. Composite, on the other hand, is pricier for installation and has fewer options for customization, but you’ll save money and time in the long run because it requires little maintenance.

The proper and most comfortable height for a deck stair riser, also called a step, is between four and seven inches. A height of seven inches is often considered ideal for a strain-free step that minimizes the risk of trips and falls. While it is possible to have risers up to 12 inches, this height can be challenging for children, pets, or individuals with mobility issues. For optimal safety and comfort, pair a seven-inch riser with a tread depth (or run) of at least 10 to 12 inches. Always check your local building codes, as they may have specific requirements that differ from these general recommendations.

Yes, pressure washing a wood deck can be a good idea as it effectively lifts ingrained dirt, mold, and mildew, improving the deck's appearance and longevity. However, it must be done carefully, as it's easy to damage the wood, especially softwoods. To pressure wash safely, use a lower pressure setting and a wide, 40-degree fan pattern nozzle (often white). Keep the nozzle at least a foot away from the wood surface and maintain constant motion, avoiding hovering in one spot to prevent gouging.

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.
