If your home feels drafty or your energy bills spike every winter, your windows may be doing more harm than good. This simple checklist will help you spot the most common signs it’s time to plan a window replacement—before the spring installation season fills up.
If you’re in Barrie, ON, we also serve nearby towns—see our Service Areas.
1) You feel drafts near the window (even when it’s closed)
A little cold glass is normal in winter, but you shouldn’t feel a steady stream of air. Drafts often come from worn weatherstripping, gaps around the frame, or older units that no longer seal tightly.
What you can do now:
- On a windy day, run your hand around the edges of the window frame and sash.
- If you feel air movement, note which rooms are worst (this helps during quoting and measuring).
2) Your windows are hard to open, close, or lock
Windows should move smoothly and lock without forcing them. If you’re fighting the sash, the frame may be out of square, hardware may be worn, or the window may be warped from age and moisture.
This matters because:
- A window that doesn’t lock properly is a security issue.
- Sticking windows are a safety issue in bedrooms (especially if a window is an emergency exit).
If you want to compare styles, here are common options:
- Casement windows (crank-open for strong airflow).
- Single sliding windows (simple and budget-friendly).
3) You see fog or moisture between the panes
If condensation is between the glass layers (not on the room-side surface), it often points to a failed seal in a multi-pane window. That can reduce insulation performance and make the window look permanently cloudy.
Quick tip:
- Wipe the inside glass. If it won’t clear because the fog is inside the unit, it’s not a cleaning issue.
4) Your energy bills are rising—and some rooms never feel comfortable
Windows affect comfort more than most homeowners realize. If one room is always colder in winter or hotter in summer, old windows may be letting heat transfer too easily or allowing air leakage around the frame.
Low-effort check:
- Compare two rooms on the same side of the house. If one room is consistently worse, it’s a strong signal to inspect the windows in that area first.
If you’re aiming for light and view (and don’t need ventilation in that spot), fixed windows can be a smart option to consider.
5) You notice water stains, peeling paint, or soft drywall near the window
Water intrusion is a “don’t wait” problem. Stains, bubbling paint, or soft trim can mean water is getting past the window or flashing, especially during freeze–thaw cycles.
Why to handle it before spring:
- Small leaks can become bigger repairs once framing or drywall is affected.
- Fixing it early can reduce the chance of mold and hidden damage.

FAQ
How do I know if I need full replacement or just a repair?
If the window won’t lock, the frame is out of square, there’s fog between panes, or you have recurring leaks, replacement is often the more reliable long-term fix.
Is condensation on the inside glass always a problem?
Not always—indoor humidity can cause condensation on cold days. Fog between panes is usually the bigger concern.
Which window style is easiest to use every day?
For many homeowners, sliders feel simple and familiar, while casements can provide strong airflow with a crank. Compare single hung windows vs double hung windows if you like the traditional up/down style.
Are sliding windows or end vent sliders better for wide openings?
For wider spaces, an end vent slider window can be a practical layout. A double slider window is another option when you want both sides to open.
How long does a typical window replacement take?
Many projects are completed in a day or two depending on the number of windows and finishing needs, but exact timing depends on the home and scope.
Do I need to replace all windows at once?
No—many homeowners replace the worst rooms first (drafty bedrooms, main living areas, or windows with leaks) and phase the rest later.
