It's not just taxes but also your monthly energy bill that can be sky high on Long Island.

A new roof, sealing up leaks around the house, insulation, and a new water heater and boiler will reduce energy costs for Ronnie from Blue Point.

These repairs can also be extremely pricey. Enter Community Development Long Island.

The nonprofit does this weatherization work to hundreds of homes in Nassau and Suffolk every year.

Depending on your income, the repairs could be free.

Most of the work being done to the house in Blue Point, like the insulation and weatherization of the windows, will improve the home's energy efficiency and save the homeowners hundreds of dollars a year in utility bills.

"Rehab efforts within a property to help decrease the energy cost, whether those are energy costs related to an air conditioner or energy costs related to keeping your heat on during the winter," said Gwen O'Shea, president and CEO of Community Development Long Island.

Community Development Long Island secures state and federal grants to fund the projects.

This work can also be done for emergency repairs.

"Let's say we have a senior that has a boiler that's broken, and they need an emergency repair, our team can go in, make that assessment for a new boiler within 48 hours," said O'Shea.
