Practical Air Sealing Tips for Windows to Save Energy
Posted on September 23rd, 2025 by Ferocious Digital
Are you noticing a draft near your windows or higher-than-usual heating and cooling bills? The culprit might be small, unseen gaps and cracks letting conditioned air escape and outside air seep in. Air sealing windows is a simple yet highly effective way to boost your home’s energy efficiency, reduce energy bills, and improve overall comfort.
Here are some practical air sealing tips from our Devine Bros team that you can use to protect your home.
Why Air Sealing Windows Matters
Drafty windows can account for a significant portion of a home’s energy loss. When your heating or cooling system works harder to maintain a consistent temperature, energy consumption and costs rise. Properly sealing these leaks creates a more comfortable living space and puts money back in your pocket.
Simple DIY Air Sealing Solutions
1. Weatherstripping:
Applying weatherstripping is one of the easiest and most common methods for air sealing windows. This self-adhesive foam or rubber stripping creates a tight seal around the moving parts of your windows, like the sash. It’s an inexpensive solution that effectively blocks drafts.
2. Caulk for Cracks:
Inspect the exterior and interior window frames for any visible cracks or gaps between the frame and the wall. Applying a high-quality exterior-grade caulk to these areas will create a durable, waterproof seal that prevents air and moisture from getting in. This is a crucial step in any air sealing project.
3. Window Insulation Film:
Consider using window insulation film for an extra layer of protection during the colder months. This plastic film is applied to the interior window frame and then heated with a hairdryer to shrink and create an airtight barrier. This transparent layer helps reduce heat loss and is easily removable in the spring.
Take Control of Your Energy Bills
