Footings for ground-level decks need to be at least 12 inches deep, and some areas require them to be even deeper. A standard range for deck footings is anywhere from 12 to 48 inches. The minimum footing depth is determined by an area’s frost line and soil conditions. If you’re unsure how deep to install deck footings, check local building codes to find the minimum footing depth in your area. 

Building a deck is often worth the investment, not only because it provides more utility to your yard and gives you more space to entertain but also because decks tend to add value to your home. Keep in mind that second-story decks often require concrete footings, which means they will bump up your property taxes, while decks built on the first story generally don’t require a permanent foundation and won’t affect your taxes. Even with the tax increase, decks are usually a good investment in the long run.

Whether composite decking is better than wood depends on your priorities, especially regarding budget and maintenance. Composite decking offers superior longevity (30 to 50 years) and durability, and it is low-maintenance, requiring no sanding, staining, or sealing. In contrast, wood decks typically last 10 to 30 years and need refinishing every few years. While the upfront cost of composite is higher than wood, the reduced maintenance can lead to long-term savings. If a lower initial cost is the primary factor, wood is the more affordable choice.

For the best results, stay off of your deck for at least 48 hours after sealing it. Giving the sealant at least two full days to cure ensures it can fully penetrate the wood, giving you the most protection from sun and weather damage later on. Walking on the deck too soon can prevent it from properly curing and cause your deck to weather prematurely.
