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 proper and most comfortable height for a deck stair riser, also called a step, is between four and seven inches. A height of seven inches is often considered ideal for a strain-free step that minimizes the risk of trips and falls. While it is possible to have risers up to 12 inches, this height can be challenging for children, pets, or individuals with mobility issues. For optimal safety and comfort, pair a seven-inch riser with a tread depth (or run) of at least 10 to 12 inches. Always check your local building codes, as they may have specific requirements that differ from these general recommendations.

While eco-friendly decking, also called composite decking, is a win for the environment because it consists of recycled materials, it has trade-offs. These sustainable options often come with steeper price tags, lack natural wood's warm look, and can become uncomfortably hot under full sun. Some composite materials can also become slick when wet, posing a potential hazard.

The best direction for a gate to swing depends on its location and purpose, but swinging inward is the general rule. An inward swing is often considered safer, prevents the gate from opening into public spaces like a sidewalk, and may be required by local building codes.

There are exceptions and specific considerations. If your property is on a slope, an inward swing might not be possible. For a deck gate, it's safest to have it swing away from any steps. In a backyard, the direction can be a matter of preference, though an inward swing can be helpful when carrying heavy items like a wheelbarrow into a garden.

Regardless of direction, ensure the gate can open fully without hitting any objects or blocking spaces. While an inward swing is standard, a gate that can swing both in and out offers the most flexibility if your setup allows for it.
