If you’ve ever stepped into your garage on a winter morning and felt an icy breeze—or noticed your energy bills creeping up without explanation—your garage may be letting in more cold air than it should. Drafts in the garage are more than just a comfort issue. They can lead to higher heating costs, damage to stored belongings, and even reduced home insulation performance.
Thankfully, draft-proofing your garage is an easy and cost-effective way to improve your home’s energy efficiency and comfort. Here’s how to do it—and why homeowners across Massachusetts trust Garage Door Experts of New England to seal the deal.
Why Drafts Are a Problem
Drafts in the garage typically occur around the garage door, windows, entry doors, and even the walls or ceiling. Left unsealed, these small openings allow cold air, moisture, and even pests to enter, particularly during New England’s harsh winters.
Besides creating uncomfortable temperature swings, drafts can:
- Increase your home’s energy consumption
- Freeze water pipes near shared garage walls
- Damage tools, paint, and other stored items
- Create unsafe working conditions if you use your garage as a workshop or gym
Step-by-Step Guide to Draft-Proofing Your Garage
1. Inspect the Garage Door Seals
The most common source of drafts is the garage door itself. Over time, the rubber bottom seal (also called a weatherstrip) wears out or detaches, allowing air and water to seep through.
Fix:
- Check for cracks, gaps, or brittleness in the bottom seal.
- Replace the weatherstripping with a new, snug-fitting seal designed for your garage door model.
- Don’t forget the side and top seals, which can also deteriorate and allow airflow.
2. Add a Threshold Seal
A garage door threshold seal attaches directly to the concrete floor and works with the door’s bottom seal to provide an extra layer of protection against drafts, rain, and insects.
Bonus: It also helps compensate for uneven garage floors, making the door seal more effective.
3. Insulate the Garage Door Panels
Many garage doors are hollow metal or fiberglass panels, which provide little to no insulation. Adding foam board or reflective insulation can drastically improve the energy efficiency of your garage.
Pro tip: If your garage is attached to your home or has a finished space above it, insulated garage doors are worth the investment.
4. Weatherstrip Entry Doors and Windows
The side door leading from your garage into your house should be sealed just like your home’s front or back doors.
To do:
- Install or replace worn weatherstripping around the door frame.
- Apply a door sweep to seal the bottom gap.
- Use caulk or foam sealant around window frames and small cracks.
5. Insulate the Walls and Ceiling
If your garage is uninsulated, it may be time to consider adding batt insulation between the wall studs and ceiling rafters. This will reduce heat loss and make any heating or cooling efforts more effective.
