Decks and Porches questions, answered by experts

Vinyl is generally considered to be the best option for homeowners seeking railings that are both durable and affordable. Vinyl provides protection against the mold and rot that can develop within wood railings. Composite is another budget-friendly option. However, people building high-end decks often prefer the look of glass panels or metal rails.

Both deck footings and deck posts help prop up your deck. However, footings are the bottommost parts of a deck that touch the ground. They’re usually made of concrete. Posts are pieces of wood that attach to the top of the footings with brackets. They run upwards and connect to the underside of your deck to support its weight.

Most two-person porch swings are rated to hold up to 500 pounds or more. However, each swing manufacturer has its own recommended weight limits, with some as low as 250 pounds while others are as high as 800 pounds. Always double-check the manufacturer’s guide and stay within the recommended range when in doubt.

Painting a damaged pool deck is not recommended if the substrate is crumbling, cracking, spalling, or otherwise actively deteriorating. Continuing deterioration will result in the paint also delaminating or flaking off the damaged surface. Minor damage such as chips or hairline cracks that are not actively deteriorating can often be repaired enough to paint over. A damaged pool deck with a lot of cracking and deterioration should be replaced for best results.

Putting lattice under a deck will create a polished look that allows for air ventilation. You can also store items underneath as the lattice provides privacy and protection from the weather. You can also put lattice under a porch to create a polished look in the front of your house.
