A Deck Builder Advises Vienna, VA Homeowners About Decks Built Over Patios
Hal Co Fence, your deck builder in Vienna, VA, says that with the right materials and proper methods, they could successfully build a long–lasting deck over an existing patio.
For starters, pressure–treated wood – wood that will not degrade and decay when it comes in contact with cement – should be used in the framing and joists. Once the joists are installed, any type of decking can be installed onto the pressure–treated stringers.
Whatever type of decking is chosen, there needs to be some airflow between the patio pad and decking boards. If not, this would lead to moisture being trapped between the surfaces and could potentially affect even the strongest products and cause premature wear out. There is also the possibility that it would void the warranty on any materials that were used.
What could prevent building a deck over an existing patio? Doorways and low–mounted windows. With a minimum of 2×2 floor joist and 3/4 inch of decking on top, the floor will be raised approximately 2 1/4 inches. This could put the deck above the threshold level, making it possible for water to leak into the home and creating a tripping hazard as well.
Also, if the pad of the patio is unstable or does not have proper drainage, it would not be wise to build a deck over it as it is. You will have to determine if it costs less to repair/improve the pad or remove it before building the deck.
Should it be determined that a deck will not work for your situation, upgrading to a tile or stone patio might be a solution. Nowadays, you also have the option of installing a heated patio that will be less likely to be damaged by our freeze/refreeze cycles in the winter.
