Pressure-treated wood decks typically last between 15 and 25 years with proper maintenance. Factors influencing longevity include local weather conditions, maintenance frequency, wood quality, and usage patterns. Regular sealing provides critical moisture protection, while prompt repairs prevent small issues from causing structural problems. Without proper care, even quality pressure-treated lumber may deteriorate significantly faster.

Most localities require building permits for deck construction, particularly for structures attached to your home or elevated above a certain height. Permit requirements vary significantly between jurisdictions, with costs typically ranging from $50 to $250. Skipping required permits may result in fines, forced removal, or complications when selling your property. Always check with your local building department before beginning construction.

While deck construction occurs year-round in many regions, late spring through early fall typically offers optimal building conditions. However, scheduling during off-peak seasons (late fall or winter) often secures better contractor availability and potentially lower rates. Weather considerations include avoiding periods of excessive rain or freezing temperatures that could complicate concrete work or wood installation.

Newly installed pressure-treated lumber requires a drying period before accepting stain or sealer properly. This waiting period typically ranges from four weeks to three months depending on your climate and the wood's initial moisture content. Testing readiness by sprinkling water on the surface helps determine when the wood will accept treatment—if water beads up, continue waiting; if it absorbs quickly, the deck is ready for staining.
