Custom Decks Built with Purpose
Not sure which color fits your space? Use the Trex® Color Selector to explore options.
At C-JAM Construction, we don’t just build decks — we create outdoor spaces that add long-term value to your home. Whether you're starting from scratch or upgrading an old structure, we use top-tier materials and overbuild where it counts.
-
Cedar, pressure-treated wood, and Trex® composite decking
-
Vinyl railings with a lifetime warranty (manufactured locally by Great Railing in Williamstown, NJ)
-
Upsized framing lumber and fasteners that exceed building code
-
Clean, code-compliant builds that hold up to time and weather
Trim Packages & Custom Options
Every deck we build comes with our standard finish package, so you never end up with a half-done job. You’ll get:
-
White PVC trim boards around the perimeter
-
Breaker board or picture frame layout included
-
One set of steps included in our standard finish option
- Optional lattice wrap, post and beam wraps, and more
​
These aren’t upgrades — they’re the details that make your deck look complete.
More Than Just Decks
We also build:
-
Covered front porches
-
Outdoor kitchens
-
Roof overhangs
-
Free-standing platforms
-
Custom railings and stair sets
If it goes outside and needs to look clean and last, we build it.
