Pressure-treated wood contains preservatives that give the material internal protection from rot and pests. Untreated lumber won’t last more than a few years unless you choose a more expensive wood, like cedar, that naturally stands up well to moisture. Composite decking can outlast wood but is more expensive and doesn’t look as natural. Keep in mind that you’ll need to seal any exterior wood product to protect it from the elements and other forms of external damage.

Homeowners should build their floating decks at least 18 inches off the ground. Having it at this height will allow for better airflow underneath and help prevent moisture-related problems like warping or rot. That being said, local guidelines for deck heights may vary depending on where you live.

A cedar deck can increase your home's value if the project is executed well. The value added by a deck is influenced by factors such as location, materials, and craftsmanship. In regions with warmer climates, decks are particularly desirable, enhancing outdoor living spaces.

The key to getting the most value out of your investment, both in terms of home value and personal enjoyment, is to make sure your deck is built to exacting standards. You should consult with a professional deck builder to get the best results and the highest ROI.

The best base materials for a ground-level or floating deck are typically gravel and crushed stone (also known as landscaping rocks). These options are inexpensive, provide excellent drainage, prevent weeds, and help minimize moisture buildup, which reduces shifting and rotting. For added stability and to evenly distribute the weight, you can use concrete deck blocks or pavers. While more expensive, concrete blocks and pavers offer a sturdier base than gravel or crushed stone alone.
