When you construct a gazebo, one option for securing it is to bolt it to an existing deck. While this option is the most secure, it is not the best option in all cases. Carefully consider what you want from your gazebo and deck before deciding how to secure your gazebo.
Bolting your gazebo to your deck ensures that it is securely fastened to a larger structure. This is important if you live in a windy region where the gazebo might be toppled in a storm. Bolting the gazebo to the deck also allows you to use the deck as the floor for the gazebo, whereas you would need to build a separate floor if you have a standalone gazebo.
Bolting your gazebo to your deck means that you cannot easily move the gazebo, and that you will need to take the time to dismount it if you want to do so. This can be problematic if you want to be able to rearrange your outdoor living space. Placing the gazebo on your deck will also give you less space than if you set up the gazebo separately.
If you want to secure the gazebo to your deck in a less permanent way, you can use metal strapping to secure the beams to the boards of the deck floor, allowing you to easily remove the gazebo, if you want to change its placement. Also, consider this: Instead of bolting your gazebo to the deck, you can, for instance, use concrete supports to hold it in place.
Making the Decision
If you want to place your gazebo on the deck, and you do not plan to move it, then the best option is to bolt it to the deck. This will secure the gazebo in place and prevent it from being damaged in the wind. If you are not certain where you want to place your gazebo, then you may want to consider a non-permanent option that will allow you to readily move it.
