Deck Maintenance questions, answered by experts

Building codes for deck railings can vary by location, so it's important to consult your local regulations before construction. Generally, a guardrail is required for any deck that is more than 30 inches above the ground.

For residential properties, the standard minimum height for a deck railing is 36 inches. However, some states and municipalities have stricter requirements; for example, California and Washington mandate railings that are at least 42 inches high. Therefore, a 42-inch railing is not considered too high and may be required in your area or chosen voluntarily for additional safety.

In addition to height requirements, codes also specify other safety features, such as the maximum spacing between balusters to ensure they are close enough to prevent a child from squeezing through.

Cold temperatures can make your deck boards contract. If they don’t contract evenly, they can put pressure on the deck screws and cause them to pop out, making a noticeable sound. Winterizing your deck can help prevent this from happening.

It is definitely worth sanding a deck to ensure the wood absorbs new stain. Sanding a deck removes the outer layers of aging wood, allowing the stain to penetrate. It also gives a fresh look to the entire surface as part of the deck refinishing process. Without sanding, your stain or sealant is less likely to absorb into the wood. While sanding a deck is a time-intensive project, the rewards are noticeable and long-lasting.

In most cases, there should be a small gap between the house and the deck, usually no more than ½ to ¾ of an inch. This space allows water and moisture to flow through instead of pooling against the side of your house. It also lets flashing protect your siding from runoff, which is one of the most common issues with decks.

The average cost to professionally clean or pressure wash a deck is around $150, with prices typically ranging from $100 to $600. Several factors influence the final price, including the deck's size, material, condition, and how long it has been since its last cleaning. For a smaller deck of about 300 square feet, you might pay around $100. For a larger deck of 1,000 square feet or more, the cost could be closer to $300 to $400. Decks that are very dirty or haven't been cleaned in years may require more time and special detergents, which will increase the price. The deck's material also plays a role. Wood decks often cost more to clean because they require a gentle power washing technique to avoid damage. Composite decks are typically less expensive to clean, and cleaning a metal deck may cost around $100.
