Finding a reliable contractor for home remodeling in Gloucester County shouldn’t feel like a gamble — yet far too many homeowners here have been burned by half-finished projects, timelines that slip for months, and phone calls that never get returned. It’s exhausting, and it’s expensive. JAM Building & Renovations was built to be the opposite of that experience. We’re a family-owned general contractor based right here in Swedesboro, and for more than 20 years we’ve remodeled kitchens, bathrooms, basements, roofs, siding, and whole homes across Gloucester County. We start AND finish on time. Named Swedesboro’s Best General Contractor of 2025 and rated 4.8 stars by our neighbors, we’d love to earn your trust. Call (856) 579-5987 for a free, no-obligation estimate.
Gloucester County is home to more than 117,000 households, spread across communities as different as historic Swedesboro, fast-growing Woolwich, upscale Mullica Hill, and busy Deptford. Roughly 80% of residents own their homes — and with that ownership comes the steady reality of remodeling: kitchens that no longer fit how families cook, bathrooms stuck in a previous decade, basements going unused, and exteriors quietly wearing down under South Jersey weather.
JAM Building & Renovations is a full-service general contractor. We take on kitchen and bathroom remodeling, basement finishing, home additions, roofing, siding, windows and doors, decks, concrete, painting, and storm-damage repair. Because we manage every phase ourselves — design, permits, construction, and final cleanup — you’re never left coordinating subcontractors or chasing down answers. From the Delaware River towns to the Camden County line, Gloucester County homeowners trust us to show up, communicate clearly, and finish what we start.

Andy meets with you personally to understand your vision, assess the space, and provide a clear, honest estimate — with no pressure and no obligation.

We handle the details that overwhelm most homeowners: design choices, permit applications, and material ordering, all coordinated for you.

Our skilled crew, led by project manager Chip, builds your project with meticulous attention to detail — and cleans up at the end of every day.

We're not done until you're completely satisfied. We walk the finished project with you and stand behind our work.
Since 2004, JAM has built its reputation one home at a time across Gloucester County. We’re not a faceless franchise
we’re your neighbors in Swedesboro, and our goal has always been to create lifetime customers rather than one-time jobs.
