Looking for a deck builder in South Jersey? JAM Building & Renovations builds, repairs, and replaces decks for homeowners in Gloucester, Salem, and Camden Counties from our Swedesboro shop.

We bid the structure we inspect—not a per-square-foot teaser that ignores footings, ledger flashing, or code. Call 856-579-5987 for a free on-site estimate.

What we handle

  • New decks (ground-level and elevated)
  • Board, rail, and stair repair
  • Ledger flashing and connection repairs that stop hidden rot at the house
  • Rebuilds when the frame is past saving

Where we work

How a deck job runs

  1. Site visit, measurements, and a look at the existing ledger and footings
  2. Written scope with material options
  3. Permits if the township requires them, then a start date
  4. Build, inspect, walkthrough

Cost honesty

Price depends on size, height, material, rail system, and whether the old ledger or footings can stay. We give a number after we see the yard.

Financing

Qualifying deck jobs can be financed. We write the price first, then you apply with our lending partner if you want to spread payments. Details: financing at JAM.
