Siding That Protects
& Transforms Your Home
New siding does more than improve curb appeal — it protects your home from Long Island's coastal weather, improves energy efficiency, and adds real value. JAGG installs, replaces, and repairs siding using materials built to perform on Long Island year-round.

Windows That Lower
Bills & Boost Comfort
Old or damaged windows are one of the biggest sources of energy loss in a Long Island home. JAGG installs energy-efficient replacement windows that lower heating and cooling costs, reduce outside noise, and dramatically improve the look of your home — inside and out.
