There are some federal grants available that assist low-income individuals and senior citizens with home repairs such as new windows and a wide range of other home improvement projects as of 2015. The grant money is generally distributed to community groups that cater to low-income families or elderly people.
The USDA's Section 504 Home Repair Loan and Grant provides funds needed for low income families to remove safety and health hazards from their homes. The grant money is then used to fix faulty heating, plumbing, or leaking roofs or to replace windows. Applicants must meet the eligibility requirements, including U.S. citizenship.
