Composite Deck Boards:
They Last Forever! The technology of composite deck/balcony boards has been around for nearly 30 years.
They are beautiful and outlast traditional Redwood by far and never need painted. They do have a tenancy to warp if not supported properly with the correct Joist interval but with the proper installation, they will stay strait and beautiful.
The Support Joists underneath the deck boards are the real concern!
Deck Support Joists:
The Joists are what really determine whether your Deck/Balcony will last. Rain water runs between the cracks of the deck boards and onto the joists causing prolonged wetness and eventually permeates the top of the Joist. Prolonged and reoccurring wetness is what causes Dry Rot followed by Termites.
Protecting the tops of the Joists by installing metal coping will keep the Joists Dry and free from Rot and Termites indefinitely.
Joist Rot Repair Before:
This is a good visual of how it starts. Many people elect to replace deck boards only, while ignoring the Joists. Luckily we were able to rebuild this deck before it was too late.
Joist Rot Repair After:
After repairing the existing Joists, we installed a protective metal coping at the tops of the beams. We then installed new Trex Deck/Balcony boards. This deck will literally last your Grandchildren's lifetime.
