The Trex cover Deck project is complete. The structure is of treated wood, sitting on 12″ centers treated structure. All the joists tops are taped, Simpson ties fitted as intended (see pics below) and stainless fasteners were used everywhere as Oregon winters are hard on decks and exposed wood. We did not install any handrails as it is not more than 30” above the yard. Am happy with build and finish quality. The new deck makes the flow from the master bedroom to outside and onto the grass effortless and it truly adds to the aesthetic and functionality of the back yard.
