Tips & Warnings

Be sure to imbed your pier blocks into the ground so that there is no risk of the spa deck sagging later on.
Make sure when you are attaching your boards to the floor joist that you use screws and not nails. Nails will work themselves out of the boards over time.
Make sure you check the level of the pier blocks and edge band before installing your deck boards.
Also check that the deck boards are not warped.
It is very important to use pressure-treated wood when an item built is made for outdoors.
A good sealer should be reapplied at least once a year for proper protection.
