Ipe decking can last up to 75 years with hardly any maintenance. That’s great! But customers often wonder: what about the framing?

Deck framing is usually made of pressure treated pine. It’s cheap, easy to install, and readily available. But pressure treated pine is only rated to last about 15 years. So why would you spend all that money on 75-year ipe if you’re going to have to replace the deck in just 15 years anyway due to rotten framing?

It’s a great question! Here are a few way to make your framing last as long as your ipe decking:

Build the Frame with Ipe

The most obvious fix is to build your frame from the same material as your decking. This will certainly work, but it will be very expensive. And because ipe is so tough, it will be a lot harder to build the frame and secure the deck boards to it. For these reasons, we don’t typically recommend going this route.

Build the Frame with Metal

Metal deck framing comes with many of the same advantages and drawback as ipe framing: it’s expensive and difficult to work with. Additionally, metal products tend to react with ipe and stain the decking. Because of this, you’ll have to use joist and ledger tape as a protective barrier between the framing and the deck boards.

Metal framing can be a great solution if you don’t mind the extra cost and effort, but we don’t usually recommend it. However, now that we’ve brought up joist and ledger tape…

Build the Frame with Pressure Treated Lumber and Protect It with Joist and Ledger Tape

The third option—and the one we recommend—is to use pressure treated pine, then cover your joists, posts, and ledgers with a protective, waterproof tape.

Most wood deterioration is caused by exposure to the elements, especially moisture. The areas of your frame that are most susceptible to rot are places where the wood touches up against something else, creating tight spaces that trap water. Common culprits are the bases of posts in contact with the ground and the tops of joists in contact with the decking.

Joist tape creates a protective barrier between the decking and the joists and keeps the wood dry. Ledger tape does the same thing, but it’s wider so it can cover a broader area. Ledger tape is good for protecting ledgers, beams, and posts.

You should apply joist and ledger tape to all your horizontal framing surfaces. The tape should be wide enough to fold over the sides for maximum protection. You may have to cut the tape in order to wrap corners without creating wrinkles, which can allow water to seep in.

Using joist and ledger tape on your deck framing will drastically improve the lifespan of your deck without costing you tons of money or effort.
