The final cost will depend on several key factors, including the size and complexity of the deck design, the materials used (wood, composite, or PVC), the location and accessibility of the project site, and whether any additional features like built-in seating or lighting are included.
It's important to get multiple local quotes from reputable deck builders to understand the specific costs in your area. They can assess your unique needs and provide a detailed estimate.
