Why Joist Tape Matters Before Installing Your Deck | Petra Decks
Why Joist Tape Is a Must-Have for Long-Lasting Decks in Sammamish, Redmond, Renton & Beyond!
At Petra Decks, we don’t just build beautiful decks—we build smart, long-lasting outdoor living spaces. One of the most overlooked yet essential steps in professional deck construction is applying joist tape before decking boards go down.
What Is Joist Tape?
Joist tape is a moisture-resistant adhesive tape applied to the top of deck joists, beams, and ledger boards. It seals screw holes and protects wood framing from water infiltration, which is one of the main causes of rot, decay, and premature structural failure.
The Benefits of Using Joist Tape
✅ Protects Your Investment
Decking materials like composite and PVC are designed to last decades. But if the wood beneath them deteriorates, your deck’s lifespan is significantly shortened. Joist tape ensures your framing lasts as long as your deck boards.
✅ Helps Prevent Rot & Corrosion
Joist tape acts as a waterproof barrier that keeps rain, snow, and dew from sitting on wood surfaces. It also helps protect fasteners from corrosion, reducing the risk of loose or weakened connections.
✅ Enhances Structural Performance
By sealing out moisture, joist tape minimizes swelling, warping, and cracking in joists. This helps keep your deck level, safe, and structurally sound year after year.
