Energy bills too high? Where your Long Island home leaks heat
The most common places older Long Island homes lose heat, and what to do about each.
Quick answer
Older Long Island homes lose the most heat through old or single-pane windows, air leaks around windows and doors, under-insulated attics, and gaps in siding and rim joists. Sealing air leaks and upgrading failing windows deliver the biggest, most lasting savings.
The usual suspects
Heat escapes through single-pane or failed windows, drafty door and window perimeters, under-insulated attics, and uninsulated walls behind old siding. Each adds to your heating and cooling bills.
Where upgrades pay off most
Air sealing and attic insulation are cost-effective first steps. But if your windows are old or failing, Energy Star replacements make the biggest permanent difference, and insulated siding tackles heat loss through the walls.
