When people think about reducing energy bills, they mostly focus on the watt consumption of home appliances, thermostats, or insulation in their walls and attic. While these are very important, one of the biggest reasons for wasted electrical energy that is often hiding in plain sight is misaligned windows and doors.
Though these openings are needed for light, ventilation, and access, they are also major weak points in a home’s energy efficiency, and understanding how these windows and doors affect your energy bills, and getting the right service to properly adjust them can save you hundreds of dollars each year while making your home more comfortable.
Heating & Cooling: Why Windows and Doors Are A Major Source Of Concern for Energy Use
1. Heat Loss in Winter
During colder months, warm air naturally moves toward cooler areas. If your windows and doors are poorly insulated or have leaks, the heated air from your home/office slips outside, forcing the furnace or heating system to run longer and using up more energy. Older single-pane windows can lose up to ten times more heat than an insulated wall.
2. Heat Gain in Summer
The reverse happens in hot weather. Outdoor heat seeps in through glass and gaps around door and window frames, making your air conditioning system work harder. Also, sun-facing windows that have no shading or special coatings can increase the temperature of a room immensely.
3. Air Leakage
Gaps and cracks around door and window frames can not only cause a security breach but also create a way for unwanted air exchange. That is why https://artanwindowworks.com/service/professional-door-adjustment-services is needed to fix it or replace it, if necessary.
4. Aesthetics & Comfort
Aside from saving on energy costs and security, misaligned door and window frames dent the aesthetics of a building or room. You don’t want to see those gaps in between frames or hear the sound of squeaky doors and windows when they are being shut or opened, or have uneven temperatures in your room.
Beyond energy costs, leaky or inefficient windows and doors cause drafts, cold spots, and uneven temperatures, making it harder to keep your living spaces comfortable.
Signs Your Windows and Doors Are Costing You Money
- Visible gaps or damage: Cracked frames, worn and missing weatherstripping and seals, and misalignments all let the needed air slip away.
- Drafts: If you feel a breeze near a closed window or door, it means air is leaking.
- Condensation between panes: This comes from a broken seal in double- or triple-pane windows.
- High energy bills: Unexplained spikes in heating or cooling costs may mean your home is losing energy through weak points.
- Difficulty maintaining consistent temperature: If one room is always hotter or colder, your windows and doors may be part of the problem.
How to Improve Efficiency and Lower Bills
The good news is that you don’t always need to replace every window or door immediately. There are cost-effective ways to improve performance before investing in upgrades.
1. Seal Leaks
- Weatherstripping: Adding or replacing weatherstripping around doors and windows prevents air infiltration. This is cheap and easy to install.
- Caulking: Use caulk to seal gaps or cracks around window frames and trim on both the interior and exterior sides.
- Door sweeps: Install sweeps or draft stoppers along the bottom of doors to keep air from escaping.
2. Upgrade Glass and Frames
- Double or Triple Glazing: Multiple panes of glass filled with insulating gases like argon greatly reduce heat transfer.
- Low-E Coatings: Low-emissivity (Low-E) glass reflects heat while allowing light in, reducing solar heat gain in summer and keeping warmth inside in winter.
- Energy Star Windows: Some certified windows meet strict efficiency standards and can cut energy use by about 12–25%.
3. Insulate Doors
Not all doors are created equal. Older solid wood doors may look beautiful, but they aren’t as efficient as modern options. For best results, you should consider:
- Insulated Fiberglass or Steel Doors: These often feature foam cores for superior insulation.
- Storm Doors: Adding a storm door provides an extra layer of insulation and protection against leaks.
4. Use Window Treatments
If replacement isn’t in the budget, strategic coverings can still make a difference. They include:
- Thermal Curtains: These are thick, insulated curtains that trap heat inside during winter and block sunlight in summer.
- Blinds and Shades: Closing blinds during the hottest part of the day can reduce cooling costs.
- Reflective Films: Window films block UV rays and reduce heat gain from the sun without sacrificing natural light.
5. Regular Maintenance
- Inspect seals and weatherstripping yearly and replace if worn.
- Keep tracks and frames clean so windows and doors close tightly.
- Repaint or refinish wooden frames to prevent warping and gaps.
When to Replace Windows and Doors
If your windows are more than 20 years old, or your doors are warped and damaged, sometimes, no amount of fixes will restore them, and replacement may be the best option, especially for the long term.
Though the initial cost of purchase may be high, modern energy-efficient windows and doors often justify their cost over time through lower energy bills. Savings of 10–25% annually are reported, in addition to increased comfort and higher resale value.
Summary
Though windows and doors may seem like small parts of your home compared to walls, roofing, or appliances, they are a major factor that affects energy consumption and costs. Drafts, poor insulation, and outdated glass can quietly drain your wallet month after month, and you would be surprised to know that even tiny leaks add up. According to the U.S. Department of Energy, air leaks around windows and doors can account for up to 30% of a home’s heating and cooling energy use.
By getting professional window and door adjustment technicians to properly seal leaks and make necessary repairs and replacements, you can significantly reduce wasted energy, lower utility bills, and save more money.
