 Attach-A-Deck: A Ledger Attachment Device Prevents Ledger Rot Eliminates need to remove siding Eliminates need for flashing Easy to use on siding, stucco, or brick Prevents mold Tested at an IAS Accredited Lab
Attach-A-Deck is a method for attaching the deck ledger to a home's band joist (rim joist) with a space between. Moisture entering into the home through flashing is a leading cause of damage and mold build-up in homes today. Attach-A-Deck helps in eliminating this problem by its self sealing design so flashing is not required and siding removal is not necessary. This ensures the home's envelope stays intact. The air gap or space between the house and the deck's ledger allows the ledger to dry following precipitation on all sides thus extending the ledger's life. It should be noted that moisture build-up between the ledger and the home leads to a more rapid 'decay' of the wood, commonly referred to as 'dry rot.' Failure of the ledger is perhaps the single leading cause of catastrophic deck failures as well as contributing to varying degrees of water damage and mold growth in homes across the country. The 'gap' provided by the Attach-A-Deck between the home and the joists and ledgers of the deck allow for movement from expansion and contraction of any decking materials.
 Key Features- Attach-A-Deck is a structural self sealing ledger spacing device.
No flashing is required in any installation.
Attach-A-Deck has eliminated the need for flashing and extensive siding removal in existing homes and streamlines new home construction. Designed for homeowners and used by contractors. The installation procedures found within the website make installation a quick and simple process. Prevents ledger rot by providing an air space.
Attach-A-Deck provides an air space between the deck ledger board and the home. When a ledger is tight to the home, water becomes trapped between the ledger and the home. Flashing does not eliminate the migration of water from occuring. This is a natural processes. And, over time this will lead to decay of the ledger which can result in failure, damage to the rim joist (band board) of the home, and moisture entering the wall space causing mold. Allows wood to 'breath'.
The structural framing woods used in deck building, along with the redwood or composite decking materials all need to 'breath' and have the opportunity to dry following storms. By placing the ledger away from the home, two concerns have been achieved. - First, the ledger can completely dry on all sides.
- Second, the space between the ledger and the home permits free movement of the decking materials to expand and contract. This is caused by thermal expansion and again, is a natural process.
A Tested Construction Product.
Attach-A-Deck has been thoroughly tested at an IAS Internationally Accredited Testing Lab and recognized by the ICC-ES. Complete copies of the testing reports are included on this web site. Easy To Use.
The Attach-A-Deck deck ledger attachment device has been used by builders and homeowners across the United States and Canada. Simply follow the instructions iin the web site. If you need help, it is a phone call away.
Attach-A-Deck Replaces the Old Weak System of Ledger Attachment Catastrophic deck failures typically occur during functions such as weddings, parties or family gathering when the deck is loaded with people which translate into weight. The failure happens when the fasteners securing the deck to the home release. What causes the release in almost every situation is a decaying of the wood fibers at the point of penetration of the fasteners caused by moisture over the years. Attempts have been made by some in the building industry to "fix the problem" by adding more fasteners which will hold a deck ledger that is going to fail on the home for a longer period of time but in the end, will not prevent the failure. By prolonging the moisture interaction between the ledger and the band joist failure, the data indicates that the wood deterioration becomes more extensive with time, with more damage to the homes band (rim) joist which could result in additional structural damage to the home itself.
