If the glass is cracked or fog has formed between the panes, you may not need to replace the whole window. We replace sealed glass units in compatible vinyl casement, awning and fixed or picture windows in Calgary and nearby communities.
Replacing only the glass can be practical when the vinyl frame, sash, hardware, and weatherstripping are still working correctly. When the complete window is drafty, damaged, leaking, difficult to operate, or outdated, full window replacement may provide better long-term value.
Can You Replace Just the Glass?
Yes, but only in specific window systems. Winmax provides glass-only replacement for compatible vinyl casement, awning, and fixed or picture windows. We do not replace glass in hung or sliding windows, or in wood or aluminum window frames.
Glass Replacement Available
- Vinyl casement windows
- Vinyl awning windows
- Vinyl fixed or picture windows
- Cracked, broken, foggy, or failed sealed units
Glass Replacement Not Available
- Single-hung or double-hung windows
- Sliding windows
- Wood window frames
- Aluminum window frames
When Glass Replacement Is Suitable
Glass-only replacement may be suitable when the problem is limited to the insulated glass unit and the existing vinyl window is otherwise sound. The frame should be straight and secure, the sash should operate properly, the locks and hardware should work, and the weatherstripping should remain effective.
- The glass is cracked or broken.
- Fog or condensation is trapped between the panes.
- The sealed glass unit has failed.
- The glass has become cloudy and cannot be cleaned from either surface.
- The vinyl frame and sash remain in good condition.
We assess the existing window and access before confirming replacement glass. The glass dimensions, thickness, spacer and fitting method must suit the existing sash.
Foggy or Failed Sealed Glass Units
Fog or water droplets between the panes usually mean the sealed unit has failed. The moisture is inside the glass unit, so cleaning either exposed surface will not remove it.
In a compatible vinyl casement, awning, or fixed window, replacing the failed sealed unit can restore a clear appearance and improve performance when the surrounding window system is still in good condition. If seal failure is combined with drafts, frame damage, poor operation, or failing hardware, replacing the complete window may be the more sensible investment.
Compatible Vinyl Window Styles
Winmax limits glass-only replacement to three compatible vinyl window categories:
- Casement windows: outward-opening windows operated by a crank.
- Awning windows: outward-opening windows hinged at the top.
- Fixed or picture windows: non-operating windows designed to provide light and an unobstructed view.
Winmax does not perform glass-only replacement in hung or sliding windows. We also do not replace glass in wood or aluminum window frames. If your window falls outside the eligible categories, our team can explain whether complete vinyl window replacement is available.
Low-E Glass, Argon Gas, and Glass Performance
Every insulated glass unit supplied by Winmax includes Low-E glass and argon gas. The Low-E coating type varies according to the selected glass package. Double-pane or triple-pane units may be supplied where the existing vinyl window system is compatible.
Tempered glass may be required in certain locations, and privacy or specialty glass may be available depending on the window, safety requirements, and product compatibility. Glass performance is only one part of the complete window system; the frame, sash, hardware, weatherstripping, and installation also affect comfort and energy efficiency.
One-Year Warranty on Glass-Only Replacement
Glass installed by Winmax as part of a glass-only replacement service is covered by a one-year warranty. This one-year warranty applies when Winmax replaces the glass or sealed unit without replacing the complete window.
Complete new Winmax windows have separate warranty terms: 25 years on the window and 10 years on the glass. Those new-window warranty terms do not apply to a glass-only replacement service.
Vinyl Window Glass Replacement Cost
The price of glass replacement depends on the size and thickness of the glass, double-pane or triple-pane construction, Low-E package, safety-glass requirements, window style, glazing method, access, and the condition of the surrounding vinyl window. An assessment is required to confirm that the window is eligible and to provide accurate pricing.
- Glass dimensions and thickness
- Casement, awning, or fixed-window construction
- Double-pane or compatible triple-pane sealed unit
- Low-E coating package and argon fill
- Tempered, privacy, or specialty glass requirements
- Access and installation complexity
Vinyl Window Glass Replacement FAQ
Can you replace just the glass instead of the whole window?
Yes, when the sealed glass unit is the main problem and the compatible vinyl frame, sash, hardware, and weatherstripping remain in good condition. Winmax provides glass-only replacement only for vinyl casement, awning, and fixed or picture windows.
Which window styles qualify for Winmax glass replacement?
Winmax replaces glass only in compatible vinyl casement, awning, and fixed or picture windows. Compatibility is confirmed after the existing window is assessed.
Do you replace glass in hung or sliding windows?
No. Winmax does not provide glass-only replacement for single-hung, double-hung, or sliding windows.
Do you replace glass in wood or aluminum window frames?
No. Winmax glass-only replacement is limited to compatible vinyl window frames.
What causes fog or condensation between window panes?
Fog or condensation between panes usually indicates that the seal of the insulated glass unit has failed and moisture has entered the sealed space.
Do replacement sealed glass units include Low-E and argon gas?
Yes. Every insulated glass unit supplied by Winmax includes Low-E glass and argon gas. The type of Low-E coating varies with the selected glass package.
What warranty applies when Winmax replaces only the glass?
Glass installed as part of a glass-only replacement service is covered by a one-year warranty. This is separate from the warranty terms provided with complete new Winmax windows.
Request a Vinyl Window Glass Assessment
Send Winmax a photo of the window and describe the problem. We will help determine whether the existing vinyl casement, awning, or fixed window may qualify for glass-only replacement or whether complete window replacement should be considered.
