Window Glass Replacement vs. Full Window Replacement: Which Should You Do?

4 min read

Whack! A baseball crashes through your kitchen window. What now? Window damage happens to all homeowners in Denver, Colorado, at one point or another. Whether it’s broken window replacement, fogged panes due to bad seals, or damaged wood framing, the dilemma remains: Is it best to do a glass-only replacement, or should you opt for a whole window replacement?

Before making any final decisions, explore all your options and consider your ultimate goal. Are you simply repairing a damaged window that’s otherwise in good shape, or are you aiming to boost your home’s value, energy efficiency, and curb appeal? Deciding between replacing glass and replacing the whole window can be tricky. Let’s answer some questions to determine whether you should replace one pane or opt for a full window replacement.

Can You Only Replace The Glass In A Window?

In short, can you replace glass in a window? Yes. Window glass replacement is a viable option when the window frame, sash, and seals are otherwise in excellent working order. This choice is almost always the more affordable option upfront.

Take that with a grain of salt, though. If you have newer, double-paned windows, the process of replacing the glass is complex and more expensive than for single-paned windows. Since many double-pane pieces of glass have gas and spacers between them, you will have to special-order each pane. If your windows are dated, leaky, single-paned, or poorly installed, it’s worth your time to consider whole-window replacement.

When Should You Only Replace the Glass?

Let’s revisit the scenario of the kitchen window shattered by a baseball. Before deciding whether to replace just the glass or the entire window, consider the overall condition of the window prior to the incident. Was there any evidence of leaking, deterioration, or improper installation? If not, opting for glass replacement may suffice. While you have the option to replace the glass independently or hire a professional, if you have a Window World replacement window, our team can efficiently handle the glass replacement for you! We’ll guide you through the process of replacing the glass yourself below.

How Do You Replace Window Glass?

Repairing broken glass on a window is generally a straightforward process, though the level of difficulty can vary depending on the type of window frame. Vinyl window frames are typically easier to work with than wood frames because of their flexibility and durability.

Preparation Phase

  1. Remove the window sash:  The window sash is the movable part of the window. Lift and pull it from the bottom to detach it. Once removed, place it on a flat surface.
  2. Prepare for safety:  Before handling the glass, ensure you’re wearing eye protection and cut-proof gloves. This will safeguard you from potential injuries.
  3. Seal broken areas with tape: Use tape to seal any shattered or broken sections of the window. This helps to bind the glass shards together and minimizes the risk of injury or mess.
  4. Try to remove the entire pane: If possible, try to remove the entire pane of glass in one piece. Wiggle it back and forth to loosen it. For older windows, you may need to use a knife to break the seal between the glass and the glazing medium.

Replacement Phase

  1. Measurements: Measure the height, width, and thickness of the pane opening. This ensures you get the correct size of glass. 
  2. Get the glass cut: Visit a glass shop or home improvement store to have the glass cut according to your measurements.
  3. Test the fit: Before installation, test the glass in the opening to ensure it fits properly.
  4. Prepare materials: Depending on the type of window, gather the necessary materials such as window glazing compound and metal glass points for wood windows, or double-sided tape for vinyl and aluminum windows.
  5. Install the glass: Set the glass in place using a bed of putty or double-sided tape. For wood windows, use window glazing compound and metal glass points to secure the glass. For vinyl and aluminum windows, seal the glass with double-sided tape. Finish by sealing the edges with silicone or glazing compound.

Keep in mind, big or small, replacing windows or window glass can be tricky, so it’s best left to the professionals. Luckily, we offer professional installation for windows. 

When Should You Consider Replacing the Whole Window?

In many cases, replacing glass vs replacing the whole window is not a real choice, as the window unit itself is the problem. A full replacement is necessary if you are seeking a permanent solution for core functionality and energy efficiency.

Three Critical Signs You Need a Full Replacement:

  1. Frame Deterioration & Drafts: If the frame is rotting, cracking, or if you feel a draft, the structural integrity is compromised. Glass-only replacement will not fix a leaky, damaged frame.
  2. Seal Failure & Fogging: While minor fogginess might be fixed by replacing the glass, severe fogginess or condensation is often caused by the entire sash being warped or improperly installed. Replacing the whole window guarantees a new, perfectly sealed unit.
  3. High Energy Bills: Old, single-pane, or poorly performing windows are a financial drain. Only a full window replacement will give you the modern thermal protection and warranty coverage needed to significantly lower your utility costs.

While window replacement has a higher upfront cost than glass replacement, you’ll reap more benefits than if you had simply replaced the glass. Glass replacement is often a quick fix. Window replacement, on the other hand, improves energy efficiency, curb appeal, and durability. You’ll notice a difference in your power bill and increase your home’s value with replacement windows.
