Making your home hurricane resistant can be a significant financial undertaking. But it’s one that has the potential to pay off as such storms become more intense amid climate change.
In 2024, the national average cost to upgrade an entire house with hurricane windows runs between $1,128 and $10,293, or $100 and $500 per window, including installation, according to This Old House. And that’s just one project.
Upgrades could help consumers protect their home, typically one of their most valuable assets, from windstorms and other natural disasters.
About $8.1 billion could be saved annually in physical damages from windstorms if homes had stronger connections between roofs and walls, or tighter nail spacing, according to a 2022 analysis on hurricane-resistant construction by the Massachusetts Institute of Technology.
‘Now’s the time to prepare’
Hurricanes are among the most expensive natural disasters in the U.S., and experts say the storm-related damage is likely to become more significant as storms become more severe.
Some of the projected effects of global warming on hurricane activity include sea level rise increasing coastal flooding, higher rainfall rates and storms that are more intense and strengthen rapidly, according to a research overview from the National Oceanic and Atmospheric Administration’s Geophysical Fluid Dynamics Laboratory.
“Warmer sea surface temperatures intensify tropical storm wind speeds, giving them the potential to deliver more damage if they make landfall,” notes the Center for Climate and Energy Solutions, a think tank.
Projections from reinsurer Swiss Re show that since the 1970s, hurricane residential-loss expectations have been on the rise, in part due to an increase in hurricane activity and changes in property value from population growth. Improvements in building standards have offset some of that increase, however.

Scientists anticipate an “extremely active” hurricane season in 2024 due to record-warm tropical and eastern subtropical Atlantic sea surface temperatures, according to hurricane researchers at Colorado State University.
The latest forecast calls for 23 named storms, 11 of which are slated to spiral into hurricanes. Of those, five are expected to reach “major” levels, or category 3, 4 or 5 storms with sustained winds of at least 111 miles per hour.
This year, the water temperature across the tropical Atlantic on average are about 1 degree Celsius, or 1.5 to 2 degrees Fahrenheit warmer than normal. While it doesn’t sound like much, it’s a big difference, said Phil Klotzbach, a senior research scientist at the Department of Atmospheric Science of Colorado State University.
“The tropical Atlantic right now is record warm,” he said. “That means more fuel for the storms…
