JAM Building & Renovations is a Swedesboro-based general contractor serving homeowners across Gloucester County, New Jersey. We focus on the work that protects and upgrades the house you already own: roofing, windows, decks, siding, kitchens, and bathrooms.
Gloucester is home base. From Swedesboro and Mullica Hill farmhouses to Glassboro faculty homes and Washington Township colonials, we already know the housing stock, permit desks, and what lasts through South Jersey humidity and freeze-thaw winters.
You get local crews, written estimates, and straight updates — not a national call center. Call 856-579-5987 for a free on-site estimate.

Local notes for Gloucester County projects
Municipalities vary on deck setbacks, roof tear-off rules, and historic-adjacent reviews (Swedesboro, Woodbury, Mullica Hill). We confirm requirements before material orders so inspections do not stall the job.
South Jersey weather rewards details: ice-and-water shield at eaves and valleys, window pan flashing, deck ledger flashing, and attic ventilation that matches the roof. Cheap shortcuts show up on the first nor’easter.
