Joist Jackets® uses revolutionary self-sealing technology. The PVC seals tight around the surface of any nail or screw inserted into the wood through Joist Jackets®. If you remove a nail or screw, the hole left behind will self-seal so that no water can penetrate the wood.
The President - David Lester "I've done a lot of deck repair and replacement over the years. I tried a couple of ideas to protect joists and stair stringers from excessive moisture" says David Lester. "What happens is the water follows the nails or screws down through the deck surface and directly into the joists via the metal pathway. Over time, the dampness causes rot around each one of those intrusions. I’ve seen 2x6 and 2x8 pressure treated lumber with only about a third of its structural strength remaining because of water damage around the fasteners. It’s expensive to replace a deck,so I started looking for ways to give decks a longer life span. That’s when I bought the patent for Joist jackets and then added the Ledger Jackets to the product line. We are so convinced that these products will prevent rot that we added a limited lifetime warranty to it."
