Window & Door Installation in New Jersey
Energy-efficient replacement windows and exterior doors installed across New Jersey — properly flashed and sealed by the same exterior crew that handles your roof and siding.
Windows and doors that seal out the weather.
Green Apple Roofing installs replacement windows and exterior doors across New Jersey. Like a roof or siding, a window or door only performs if it's installed right — flashed, sealed, and insulated so air and water stay outside where they belong.
Green Apple was built around the home's exterior: roofing, siding, gutters, and windows. That means the same crew can handle the full weather envelope, and the trim, flashing, and siding around a new window are finished cleanly — not left for someone else to patch.
Energy-efficient windows cut drafts and lower heating and cooling bills; a solid, well-hung exterior door improves security and curb appeal. Every project starts with an estimate, and we'll beat or match any reliable, legitimate roofing, siding or gutter quote.
