Deck Maintenance FAQs, answered by experts

For a 12x20-foot (240-square-foot) deck, you can expect to pay between $7,200 and $14,400. This cost is based on a general price of $30 to $60 per square foot. The final price will depend on factors such as the decking material, design complexity, deck type, location, and local labor costs. Keep in mind that add-ons will increase the total; for example, adding an under-deck drainage system to a deck of this size could cost an additional $7,700.

When deciding if you should use 2x6 or 2x8 deck joists, consider the size of the deck, joist spacing, and materials. Larger decks, larger-spaced joists, and weaker wood all require more support, meaning they need larger joists. For example, 2x8 redwood joists spaced 16 inches apart can only safely span up to 10 feet and 7 inches. On the other hand, 2x10 southern pine joists spaced 12 inches apart can be as big as 16 feet and 2 inches. If you aren’t sure what size joist is best for your project, speak with your deck builder.

A sunroom will add more value to your home than a deck, but with a much higher up-front cost. Depending on its construction and function, a sunroom may be counted as additional living space, while a deck is strictly an outdoor feature. Both will increase your home’s value, but the sunroom will have a much bigger effect.

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.

Routine cleaning, sealing/staining, and inspection prolong deck life and appearance.
