Building a new Trex deck for an Allentown, PA home
Deck Construction · Allentown, PA · completed May 2026
This deck construction job in Allentown, PA started from nothing. We just wrapped it up. The homeowners wanted a good spot to spend time outside, and now they've got one.
The problem
There was no old deck to work from, so everything had to be built right from the ground up. We paid the most attention to two things: the framing and the spot where the deck connects to the house.
What we did
We framed it new with structural joists and fastened a ledger board to the house. Joist tape went across the tops of the joists to protect them. We flashed the ledger too, so the connection to the house stays tight and water doesn't get in behind it.
Materials
Trex Composite deck
