How to Winter-Proof Your Patio Doors

Wisconsin winters are beautiful, but they’re also brutal on your home’s energy efficiency. If your patio doors are older, drafty, or poorly sealed, they could be letting in cold air and driving up your heating costs. Whether you’re looking for a quick fix or a long-term solution, here’s how to winter-proof your patio doors.

Seal the Gaps with Weatherstripping

Even a small gap around your patio door can lead to major heat loss. Start your winterization process by checking for worn or missing weatherstripping around the frame and door edges.

Solution: Install new, high-quality weatherstripping made for patio doors. This quick upgrade can significantly reduce drafts and improve insulation.

Block Under-Door Drafts with a Door Sweep

The space beneath your patio door is a common source of leaking air. Installing a door sweep or draft stopper can block out winter air and prevent heat frome scaping.

Pro tip: Choose a brush-style sweep for sliding doors or a rubber fin design for hinged doors.

Add Thermal Insulated Curtains

Patio doors let in light but they can also let out heat. Hanging insulated or thermal lined curtains can help trap warm air inside your home, especially during frigid nights.

Look for:

  • Floor-to-ceiling panels
  • Magnetic closures or weighted hems
  • Energy-effiecient fabric with a thermal backing
  • Maintain Sliding Door Tracks

If your sliding patio door isn’t closing tightly, dirty or misaligned tracks may be the problem. A poor seal allows cold air to seep in.

The fix:

  • Clean the tracks and rollers
  • Lubricate with a silicone-based spray
  • Adjust the rollers to ensure a tight fit
