"Our Deck was replaced with pavers for fire mitigation. Nate did a super job laying the pavers on two separate levels. Because of the very good work that he did for us we had him come back and do several handyman projects in our home."

Deck Maintenance questions, answered by experts

Composite decking requires a solid foundation or substructure for support. This base is typically a frame composed of posts, beams, joists, and footings. The frame can be built from various materials, such as composite, plastic, timber, or metal, depending on your budget, deck type, and environmental conditions. For maximum stability, a professional deck builder may recommend installing this frame on top of a solid concrete base. It is best to discuss the most suitable substructure design and materials for your specific project with a professional.

The life expectancy of deck boards varies widely based on the material, climate, and maintenance. Untreated wood boards typically last 10 to 30 years with proper care, while pressure-treated boards can last up to 50 years. Hardwoods generally outlast softwoods. Composite boards also tend to last longer than natural wood. Environmental factors like arid or humid climates can shorten a deck's lifespan. To extend the life of wood decking, it's important to consistently clean and seal it to protect against moisture, UV light, and insects.

How long it takes to install composite decking depends on the size of the decking material, the skills of the person installing the deck, the number of people helping, and how much prep work needs to be done before you can begin. Generally speaking, it takes anywhere from a few days to several weeks to build a composite deck.

Expect to spend around $10,000 to $11,000 to replace a 20-by-20-foot deck. Using high-end materials like composite or exotic hardwoods can drive up the cost, as can custom features and design elements. You can also expect to pay more than average if your deck replacement requires a site evaluation or if you need the work done during the busy season.

Whether to paint or stain a deck depends on your personal preference for appearance and budget. Stain provides a natural look with a range of undertones, is typically less expensive, and may only require one coat, but it does not last as long as paint. Paint offers a sleeker finish with a virtually unlimited color palette. Both options will protect your deck from outdoor elements like rain, snow, and general wear and tear.
