For many, a deck is an extension of the home. It brings indoor life to the great outdoors. With a little care, a deck can last for many years. Neglected, it can become an eyesore or worse, unsafe! This spotlight on decks provides a few tips to help keep your deck safe and in good condition.
Deck Materials
Pressure Treated Wood: The most common deck building material is pressure treated wood. Properly maintained, a pressure treated wood deck can last 20 years. Pressure treated wood comes in construction grade and premium grade. Construction grade, pressure treated wood tends to warp and split as it dries and shrinks. This is fine for the deck structure but the decking calls for a higher quality material. Premium pressure treated deck boards are cut from better stock and are treated and dried to a higher standard.
Cedar: Cedar is a premium deck building material with a rich look and feel. It is more expensive than pressure treated wood but it has many desirable properties. It is naturally more dimensionally stable than pressure treated wood so it does not shrink and split. A well maintained cedar deck can last 20 years.
Synthetic: Synthetic decking is the most expensive decking material but it requires little to no maintenance beyond cleaning and should last many years. There are many different types and styles.
Wood Sealer
The secret to a deck that looks good over the years is wood sealer. Unsealed wood will absorb water and expand and then dry out and shrink. Over time the wood splits and deteriorates. If the water beads up and runs off, the deck is in good shape. Otherwise it needs sealer.
Guard Rails
Guard rails keep you safe on your deck. The point is to keep people from falling from the deck. Guards are generally required for decks higher than 24 inches and 30 inches from the ground.
•The guard rail should be 36 inches high (a deck over 6 feet high requires a 42 inch guard)(Requirements may vary by location).
•There should be no openings larger than 4 inches so nobody can fall through or trap children.
•It should be strong enough to hold a person that falls heavily into the rail or balusters.
Deck Collapse
Except for hurricanes and tornadoes, more injuries may be connected to deck failures than all other wood building components and loading cases combined. Many decks fail because they are old, worn and rotted. Others fail because they were not built properly in the first place. The most critical connection is the deck to house connection.
