Sewell, New Jersey

A Sewell-based contractor for Sewell homes

Big Cat General Contractor is based in Sewell, so this is home ground for us. Sewell is not a municipality of its own. It is an unincorporated community in Mantua Township, and the Sewell mailing address also covers a large part of neighboring Washington Township. Rowan College of South Jersey is here, and Washington Lake Park and Bells Lake are nearby.

Most Sewell homes date from the suburban growth that turned these farm townships into neighborhoods. In the 1960s, Washington Township was a handful of separate developments such as Wedgwood, Whitman Square, the Birches and Hurffville, and it kept expanding from there. Census estimates put Washington Township's median home at 1982 and Mantua Township's at 1987, and about three-quarters of homes in both are single-family detached houses.

Local considerations

Local considerations in Sewell

  • Which township issues your permit? Because Sewell addresses fall in both Washington Township and Mantua Township, permits go to whichever municipality your property is actually in. Your property tax bill shows it. We file with the right construction office either way.
  • Housing stock. Much of Sewell was built from the 1970s through the 1990s, so original kitchens, baths and roofs are often due for replacement. Older farmhouses and homes near Barnsboro and Hurffville may date from before 1978, when lead paint was still in use.
  • Basements and moisture. Gloucester County sits on low-lying coastal plain with many creeks. Summer humidity and heavy rain can make basements damp, so moisture control comes before finishing.
  • Associations and newer developments. Some Sewell neighborhoods have homeowners associations that approve exterior changes such as roofing color, siding and decks. Check your association rules before you schedule; we can provide product details for the application.
  • Weather. Freeze-thaw cycles and nor'easters are hard on shingles, flashing and gutters. Many ice dams can be prevented with better attic insulation and ventilation.

Do you finish basements in Sewell homes?

Yes. We check for moisture, drainage and egress first, then frame, insulate, drywall and finish. Finished basements need permits and inspections, which we handle.

Yes. We serve all of Washington Township, including Turnersville, Grenloch and Hurffville, as well as Mantua, Barnsboro and Pitman.

Can you replace my roof and gutters at the same time?

Yes. Replacing both together lets us install drip edge, flashing and gutters as one system, which helps prevent the leaks and ice dams that start at the roof edge.
