For a standard wood deck in the San Jose area, you should expect to pay between $35 and $60 per square foot for professional installation. This price range covers materials like pressure-treated lumber or cedar, labor, and basic permits. For a 300-square-foot deck, that translates to roughly $10,500 to $18,000. High-end materials like composite decking or exotic hardwoods will push costs higher, often $50 to $80 per square foot. The final price also depends on your deck's height, complexity, and any built-in features like railings or steps. To ensure a fair estimate, always get at least three detailed quotes.

The 3 4 5 rule is a fundamental method used in construction, including decking, to ensure corners are perfectly square. It is based on the Pythagorean theorem. To apply it, measure three feet from a corner along one side of your deck frame, and mark that point. Then, measure four feet from the same corner along the adjacent side, and mark that point. The distance between these two marks should be exactly five feet. If it is not, you must adjust the frame until the measurement is correct. This simple check guarantees a true 90-degree angle for your deck's foundation. For complex layouts, D&D Home Remodeling recommends using this rule in conjunction with a quality carpenter's square for the most accurate results.
