Support posts which are mounted in the interior of the deck will be flashed and sealed. There may be occasions where you see drips from time to time.

Some railing systems require the support posts to protrude through the deck surface and anchor to the structure below. In most cases it is impossible to adequately flash these areas. Some dripping may occur over time.

Any features on the deck which prohibit the insertion of flashing material. To the best of our ability we will identify these areas to the homeowner and advise as to whether the ‘No Leak’ warranty can be applied to these area(s).

The homeowner must ensure that the deck ledger board has been properly flashed prior to installation of the Under Deck Oasis. Absence of this flashing will allow water to drain behind the ledger and down the wall. This phenomenon is outside of the systems ability to redirect this water.

Masonry work can seep water from time to time. This phenomenon is outside of the systems ability to re-direct this water.

Similar to the above ‘porous masonry’ issue, any water which is entering the building structure above the deck surface and exiting below the deck onto the patio is outside of the systems ability to re-direct this water.

It is important that during the winter months no external heat sources such as lights or heaters be kept operating for a lengthy period of time.

Sometimes with older decks the structural wood may split or crack. The warranty will cover this as long as we can adequately flash and seal these areas during the installation.
