Insulate your home

Cut energy bills and keep your home more comfortable by sealing your home with properly installed insulation of at least an R-38 insulating level. Air leaks not only make you uncomfortably hot in summer and cold in winter, but they waste energy, too.

Skill level: Advanced to professional
Start with your attic, which is generally the most cost-effective place to add insulation. If your home still feels drafty in winter or warm in summer, you may need to add insulation to your exterior walls, crawl space or basement.
Cost range: Varies
If your home is poorly insulated, adding or upgrading insulation will pay for itself over time with lower energy bills.
Savings: About $200 annually
Properly installed insulation is one of the best ways to increase comfort and overall energy performance.
