Deck Repair FAQs, answered by experts

You should refinish your deck to maintain its appearance, durability, and longevity. Refinishing your deck protects the wood from foot traffic and the elements. It also helps extend its life span by keeping rot, mildew, and termites at bay. By maintaining your deck, you can avoid the cost of replacing your deck sooner. A refinished deck also looks great and restores some of its original beauty.

There are more pros than cons when staining a deck. Deck stain is more affordable than paint, it protects the wood and allows the natural textures to shine through, and it can revive the appearance of your home. However, deck stain also requires prep work (sometimes days or more), carries more upkeep than a painted deck, and can fade over time if not cared for. 

Yes, you can build a deck over your outdoor HVAC unit, but you need to leave at least 5 feet of vertical clearance above the unit. If you don’t want your deck to be that high off the ground, you could build a floating deck in another part of your yard—again, as long as you leave at least 4 feet of horizontal space between the deck and your AC unit.

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.

Hangers are one way of attaching stair stringers to a deck. These metal hangers are usually adjustable, allowing you to find the ideal angle for a secure installation. They’re the best choice for installing longer staircases, such as one on a two-story deck, to reduce the load on the deck frame while keeping the stairs stable.
