As the snow begins to fall and temperatures drop, homeowners in the Greater Toronto Area (GTA) face the annual challenge of keeping our homes warm and cozy while managing energy costs. Drafty windows and doors can be a major culprit behind heat loss, higher energy bills, and an uncomfortable home. At Casa Bella, we specialize in high-quality windows and doors tailored to the unique needs of GTA homeowners. Here’s what you can do to winterize your home for a warm and energy-efficient holiday season.
Why Winterizing Windows and Doors Matters
Winterizing your windows and doors is essential for maintaining indoor comfort, saving money, and reducing your carbon footprint. Energy-efficient homes with modern window designs are better for the environment and our future generations. According to Natural Resources Canada, up to 25% of a home’s heat loss can occur through windows and doors. Addressing this heat loss ensures your family stays warm without having to crank up the thermostat.
Step-by-Step Guide to Winterizing Your Windows and Doors
Inspect and Assess Your Windows and Doors
Before doing anything, you need to know where you stand and what to prioritize. When you inspect your windows and doors, look for:
- Visible gaps or cracks around frames.
- Signs of moisture or condensation between window panes.
- Drafts coming through door frames or window edges.
- Worn-out weatherstripping.
A quick way to detect drafts is by holding a lit candle or incense stick near window edges and door frames on a windy day. If the flame flickers or smoke wavers, you likely have a draft.
Seal Gaps and Cracks
Gaps and cracks around windows and door frames are major culprits for letting cold air in and warm air escape.
For Small Cracks:
- Clean the Area. Wipe down the frame with a damp cloth to remove dust and debris.
- Apply Caulk. Make sure the caulk is suitable for the frame material.
- Smooth the Surface. Use a putty knife to smooth the caulk into the crack and make it flush with the surface.
- Allow it to Dry. Follow the manufacturer’s instructions for drying time before painting over it.
For Larger Gaps:
- Insert Foam Backer Rod. For gaps wider than 1/4 inch, push a foam backer rod into the gap first to provide a base for the caulk.
- Caulk Over Backer Rod. Apply caulk over the backer rod, smoothing it out as described above.
- Use Expandable Foam if Needed. For very large gaps, you may need expandable foam. Once cured, trim it flush with a utility knife.
For Door Frame Gaps:
- Fill Under the Door Frame. If there are gaps between the door frame and floor, use shims to fill this space first, ensuring they are recessed slightly below the frame.
- Apply Latex Caulk. After securing the shims, apply latex caulk over the gap and smooth it out.
Final Touches
- Paint Over Repairs. Once everything is dry, you can paint over the repaired areas to match your existing decor.
- Regular Maintenance. Periodically inspect your window and door frames for new cracks or gaps to prevent larger issues in the future.
Larger gaps may indicate more serious issues. Consult a professional if you suspect they’re due to structural problems.
Replace Worn-Out Weatherstripping
Weatherstripping is your first line of defence against drafts. Over time, weatherstripping can wear out, compromising its effectiveness. Replace damaged or old weather stripping on doors and windows with high-quality materials such as adhesive-backed foam tape, V-strip, or tubular rubber seals.
Pay special attention to door sweeps, which seal the gap between the bottom of the door and the floor. A properly installed door sweep can significantly reduce drafts.
As a reminder, our windows contain triple weather stripping if you’re considering window replacement, and our doors have full perimeter compression weather stripping that ensures a tight seal and minimizes heat loss.
Add Window Insulation Film
Window insulation film is a cost-effective way to improve the thermal efficiency of older windows. These transparent films are easy to install and create an additional barrier against cold air by reducing heat transfer.
Most insulation film kits come with double-sided tape and shrink-wrap plastic that you can apply to the inside of the window frame. Once applied, use a hair dryer to shrink the plastic for a tight, clear seal.
Install Thermal Curtains or Blinds
Adding thermal curtains or insulated blinds can be a stylish and functional way to improve your home’s energy efficiency. These window treatments are designed to block drafts and trap heat indoors. During the day, open curtains to let natural sunlight warm your home. At night, close them to retain heat.
Address the Small Details
Don’t overlook the smaller elements that contribute to drafts and heat loss. Some simple yet effective solutions include:
- Using draft stoppers at the base of exterior doors.
- Installing foam gaskets behind electrical outlets and switch plates on exterior walls.
- Sealing mail slots and pet doors with insulated covers.
Upgrade to Energy-Efficient Windows
If your windows are outdated or consistently drafty, it may be time to consider replacing them with energy-efficient models. Look for windows with:
- Low-emissivity (Low-E) glass that reflects heat back into the room.
- Argon or krypton gas fills for enhanced insulation.
- Double- or triple-pane construction to reduce heat transfer.
Casa Bella fabricates and installs a wide selection of ENERGY STAR®-certified stock, custom, and decorative windows specifically designed for the harsh Canadian winters. Replacing old windows with modern, efficient ones translates to significant long-term savings on heating costs.
Our bay and bow windows, for example, add a dramatic accent and contour to your home, increase the amount of natural light it gets, and enhance your holiday decorations.
Upgrade Your Exterior Doors
Just like windows, doors play a vital role in keeping your home warm. If your door is warped, damaged, or made from a material that lacks insulation, consider upgrading to an insulated steel or fiberglass door. These materials don’t warp, provide excellent thermal performance, and are built to withstand the elements.
For sliding patio doors, ensure the tracks are clean and the seals are intact. Consider installing insulated sliding garden doors for better energy efficiency.
Maintain Proper Ventilation
While sealing your home is essential, maintaining proper ventilation is equally important to prevent indoor air quality issues and excess humidity. Ensure your home’s ventilation system is functioning properly, and consider using a heat recovery ventilator (HRV) to exchange stale indoor air for fresh outdoor air without losing heat.
Additional Tips for Energy Efficiency
- Schedule a Professional Energy Audit. A certified energy auditor can pinpoint specific areas where your home is losing heat and recommend tailored solutions.
- Monitor Humidity Levels. Excess humidity can lead to condensation on windows, potentially causing mould or rot. Use a dehumidifier to maintain ideal indoor humidity levels between 30% and 50%.
- Upgrade Your HVAC System. An efficient furnace or heat pump can make a significant difference in your heating bills. Ensure your HVAC system is regularly serviced and operating efficiently.
