How to Prepare Your Windows & Doors for Winter in Alaska
Winter settles quickly here in Alaska. The days get shorter, the temperatures drop and the warmth of your home becomes a comforting refuge. But that comfort can be reduced if your windows aren’t properly prepared for winter. Winterizing your windows is a smart way to keep heat inside and prevent cold air from entering. Let's take a look at why winterizing your windows matters and how to do it effectively.
Why You Should Winterize Your Windows
Preparing your windows for winter has several benefits. It’s an affordable way to boost your home’s energy efficiency, comfort, and lifespan.
- Energy Efficiency: Windows that leak air or lack proper insulation can cause significant heat loss during winter. Sealing gaps and cracks reduces heat escaping and prevents cold drafts from entering. This can lower your energy bills and reduce your overall energy use.
- Comfort: A home with well-prepared windows is more comfortable in cold weather. Proper insulation helps maintain a consistent temperature indoors, eliminating cold spots and drafts that make rooms less cozy.
- Longevity: Checking your windows before winter can protect them from harsh conditions. Proper sealing and insulation prevent water from entering and freezing, which can lead to damage over time. Winterizing your windows helps extend their life and reduce maintenance costs.
How to Winterize Your Windows
If you have new Pella windows, they’re designed to perform well year-round—just locking them is usually enough. Older windows, however, can develop drafts, leaks, and inefficiencies over time. To minimize the effects of winter weather, follow these steps annually to keep your windows in top shape:
- Seal and Caulk Windows
The caulking around your windows creates a barrier between the window frame and exterior. Check it yearly, especially at corners and joints where water can accumulate. Cracked, brittle, or missing caulking should be replaced. We recommend using a high-quality sealant, like Pella Window and Door Installation Sealant, which is durable, weather-resistant, and effective in a wide range of temperatures. - Replace Weatherstripping
Next, check the weatherstripping between the window sash and frame. Tight, effective weatherstripping prevents drafts and water leaks. If it’s worn out, replace it or request service from a professional. Common types include:- Adhesive-backed foam for small gaps
- Tubular rubber gaskets for flexible sealing
- Spring V-seals for tensioned draft protection
- Felt strips, an older option that works in a pinch
- Check Locks and Latches
Windows that don’t close properly can let air and moisture in. Test each window to ensure locks and latches operate smoothly. Clean and lubricate mechanisms if needed. If a lock still doesn’t work, repair or replace it. Once everything is functioning, make sure all windows are securely closed and locked for the season.
Maintaining Energy-Efficient Windows
Winterizing windows is all about energy efficiency. Proper sealing, weatherstripping, and locking help your windows perform their best during cold months. Over time, however, older windows may become less effective. If you notice drafts or increased heating use, it might be time to consider replacing your windows.
