Glass Only vs. Window Replacement

Do you have a broken glass pane? Do you see condensation between the glass in your windows (aka "foggy windows")? Are rooms cold or hot? Can you easily hear outside noise?

The glass in your window blocks air and allows light to enter, but the glass alone has no significant insulation properties. It is what’s on and within the glass that contribute to energy performance – such as non-toxic argon gas between panes and low-e coatings. These will offer better insulation and keep your home warmer in the winter, cooler in the summer.

Many homeowners have trouble deciding if they need window glass replacement or total window replacement. To make an informed decision, read on.

Glass Replacement – The temporary solution

Window glass replacement involves removing the broken or failed window pane from your window frame and replacing it with the closest match. The process takes about 45 minutes per pane. It is typically a good option when you are dealing with low-e glass in a new, otherwise undamaged frame. Replacing only the glass in older windows results in a temporary solution that lasts only until the next window seal fails.

Window Replacement – The long term solution

Window replacement involves removing the existing glass and frame and installing a brand new window. The process takes about an hour per window. If your windows have non-low-e glass, single-pane glass, or are in poor working condition, it makes sense to replace the entire window. Replacing the entire window results in a long-term solution (typically backed by a lifetime, limited frame warranty and a 20-year glass warranty).

When Should You Opt for Glass Replacement?

When your window frames are in good shape and your glass is already high-performance low-e, but

-There is a broken or cracked pane(s) of glass

-There is fogging or condensation between existing panes of glass

-The existing wood frames are historic and need to be preserved

-Lowest possible immediate cost

When Should I Choose Window Replacement?

When you have older windows and

-The glass is inefficient single-pane or non-low-e

-The window frames are in bad shape (trouble opening, air infiltration / drafts, damaged, or discolored)

-There is damage due to water infiltration, or moisture-related mold growth

-Appreciate the benefits of a larger investment

Replacement Windows vs. Replacement Glass: How Do the Costs Compare?

The typical cost for replacing window glass is around $300 per pane (typically two panes per window). Tempered/impact-resistant glass (near a door, near stairs, or over a bathtub, for example) being as much as double. Replacement windows on the other hand, typically run $650-$1,500, depending on size, glass type, and frame material.

Final Thoughts

Replacing the glass is a good option in certain circumstances (no other issues and already low-e glass). Replacing the entire window is often a more practical, long-term, and cost-effective solution. With a complete window replacement, buyers can ensure that all aspects of the window are corrected and include the latest energy efficiency, noise reduction, and security features. Additionally, replacing the whole window provides an opportunity to update and enhance the overall appearance of your home, which can increase its value and curb appeal. Investing in a new window is a long-term solution that offers unmatched peace of mind.
