Even though Southern California is known for sunshine and mild temperatures, residents of Glendale and Pasadena know that winter brings chilly evenings, gusty winds, and the occasional rainstorm. Before cold weather arrives, it’s important to make sure your windows are prepared to keep your home warm, comfortable, and energy efficient. At American Reliable Windows & Doors, we’ve helped homeowners throughout the San Fernando Valley and Los Angeles area identify and replace drafty windows for more than 20 years. Here’s how you can spot the signs early and take action before temperatures drop.
Why Finding Drafty Windows Early Matters
Drafty windows may seem like a small inconvenience, but they can lead to bigger issues over time. When cold air leaks into your home, your heating system has to work harder, leading to higher energy costs and a less comfortable indoor environment.
In areas like Glendale and Pasadena, where many homes are older and experience seasonal shifts, even small drafts can have noticeable effects. Identifying the problem early allows you to fix or replace windows before winter weather hits.
Common Signs Your Windows Are Letting in Drafts
Drafty windows aren’t always obvious. Some show visible signs, while others require closer inspection. Here are the most common indicators homeowners should watch for:
Noticeable Temperature Changes Near Windows
If one room feels colder than the others, or you feel a chill when sitting near a window, it’s a clear sign of air infiltration. This often happens in older homes throughout Pasadena and parts of Glendale where original wood windows may have worn over time.
Higher Than Usual Utility Bills
When your heating system works overtime to maintain warmth, your energy bills begin creeping upward. If you notice an unexplained spike in fall or winter, drafty windows may be to blame.
Condensation or Fog Between Panes
Moisture trapped between panes indicates seal failure, meaning the insulating gas has escaped. This is a common issue in aging double-pane windows across Southern California.
Visible Gaps or Warping
Time, sun exposure, and temperature shifts can cause window frames to expand, contract, and warp. Any noticeable gaps, especially in older homes, can let cold air in and warm air out.
Curtains Moving When the Windows Are Closed
If you see curtains sway or blinds shift when the window is fully closed, air is flowing where it shouldn’t be.
Simple At-Home Tests to Detect Drafts
You don’t need professional tools to identify air leaks. A few quick tests can help pinpoint problem windows:
The Candle Test
- Light a candle or incense stick
- Hold it near window edges
- Watch for flickering or moving smoke
Any movement indicates an air leak.
The Hand Test
- Place your hand around the perimeter of the closed window
- Feel for pockets of cold air or temperature shifts
This is especially noticeable at night when outdoor temperatures drop.
The Flashlight Test
Have someone stand outside your home at night while you shine a flashlight from inside around the window frame. If light passes through, so does air.
What Causes Drafty Windows in Glendale & Pasadena?
Homes in these cities experience unique factors that contribute to window drafts:
- Older homes: Many Glendale and Pasadena neighborhoods feature charming historic houses with original windows that simply weren’t designed for modern efficiency.
- Sun exposure: Southern California sunlight can dry out seals and weatherstripping.
- Earth movement: Minor shifts over time can create gaps between frames and walls.
- Wear and tear: Everyday opening and closing eventually weakens components.
When Replacement Is the Best Option
Not all windows can be repaired effectively—especially if they’re decades old or severely damaged. Installing new, energy-efficient windows provides homeowners with:
- Better insulation
- Enhanced comfort
- Reduced noise
- Improved curb appeal
- Lower energy bills
- Long-lasting performance
