Thousands of Floridians applied for a state grant program that pays up to $10,000 for home-hardening improvements in the month after it received another $100 million and expanded across the state. For Floridians with older homes, the program is a good deal: It offers $2 for every $1 spent on strengthening potential weak points that can be breached in large storms, such as roofs, windows, garage doors and exterior doors. But it looks like all of the available funding will be earmarked to applicants before most of the newest participants will have an opportunity to be approved. In the first month after becoming available throughout Florida, the My Safe Florida Home program accepted 16,506 new applications for inspections, according to newly released data.
