Deck Repair FAQs, answered by experts

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.

Pavers are a great decking option for pools. They’re customizable, come in a variety of shapes, sizes, colors, textures, materials, and price points, and they’re slip-resistant. Concrete pool decks, on the other hand, are harder to repair and replace if damaged and aren’t as slip-resistant as most paver materials. However, not all pavers are equal in terms of durability, maintenance, and performance. Pavers also have their own cons that may encourage homeowners to opt for stamped concrete instead, such as higher upfront costs.

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. 

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.

An above-ground pool with a deck can increase your home's value by as much as 4% to 7%, but it depends on your local climate, potential buyers, and the size and condition of your pool. Some buyers see a pool as a liability instead of a luxury, especially if it's at the end of its life span. In general, it's best to add a pool and deck to your property if it will bring you enjoyment—not because it raises the value of your home.
