When you consider adding a deck to your home, one of the things that you want to know is how long it will last. Most decks will last 10-30 years, and the average length of time is 15 years. It can last a little longer or shorter, depending on the amount of weather that it’s subjected to and how well it’s maintained.
Here are just a few of the factors that can make a difference:
If you are looking for a location for your deck, the best place to put it is dappled, moderate shade for most of daylight hours. Continuous, blazing sun is going to deteriorate your boards and the sealant that has been applied for protecting them. of course, you also don’t want to have it in a heavily shaded area, since this can keep its surface wet, and this will promote wood rot.
When you purchase a better lumber grade, one that has fewer checks, knots and other kinds of defects, it’s going to extend your deck’s life. Generally, the lumber at a home improvement store is going to be #2 grade. However, you can also find #1 grade. The structure will be stronger, there are going to be fewer knots, and there will be less cupping and twisting. The appearance will also be better.
