Finding a cracked window pane in your home might make you consider a costly replacement. However, you can often fix the crack yourself, preventing it from worsening and potentially shattering. This approach can also give you time to save up for a future replacement rather than facing an unexpected expense. While there are numerous ways to temporarily or permanently fix a cracked window, not all methods are equally reliable. Below is a list of options, ranked from the least to the most effective.
Use tape to seal a cracked glass pane
The simplest and least sophisticated way to fix a cracked window is to use strong clear adhesive tape, such as packing tape, and apply it over the damaged area. This method helps stabilize the crack, reduces stress on the glass, and prevents the crack from spreading. Additionally, it seals the area, preventing air from leaking in or out.
It’s worth noting that for double-pane windows, a significant crack can damage the gas layer between the panes, reducing the window’s insulating efficiency. However, if the crack is minor and hasn’t fully split the glass, clear tape can serve as a temporary, albeit unattractive, solution until a more permanent fix is implemented.
Repair a crack using glass repair film
A more advanced alternative to regular tape is glass repair film, which functions like reinforced tape. It’s specifically designed to be applied quickly and easily, sealing and stabilizing the crack to make it weatherproof and prevent further damage. This method provides stronger protection than standard tape and can be customized to fit larger cracks. While the crack will still be visible, this solution eliminates concerns about broken glass, drafts, or water infiltration.
Temporarily fix a cracked window with clear nail polish
Clear nail polish can serve as a short-term solution for a cracked window. Start by cleaning the area, then use painter’s tape to outline the crack. Apply the nail polish generously, ensuring it fills the crack. A second coat may be necessary after the first layer dries to fully seal the damage.
This method offers a more robust solution compared to tape or film, as the crack is filled with a clear and somewhat durable material. However, nail polish isn’t built to endure moisture or extreme temperature changes, so it won’t last indefinitely. Pairing nail polish with tape or film can extend its lifespan, but it will still degrade over time.
Repair a crack using super glue
Similar to nail polish, clear super glue such as Loctite Glass Glue or Gorilla Glue can fill and reinforce the crack in your window. This approach is slightly more durable because super glue, especially types designed for glass, is engineered to handle greater stress. It might even serve as a semi-permanent solution if you’re okay with a visible flaw. Take care to apply the glue meticulously to reduce the crack’s visibility.
Epoxy
For the most effective repair short of replacing the window, an epoxy-based solution is ideal. Any clear two-part epoxy will work, or you can use a car windshield repair kit, which typically includes epoxy. These kits come with necessary tools and instructions, but you can also repair the window yourself using a putty knife and proper preparation. Epoxy repairs are highly durable, and with careful application, the crack can become nearly invisible.
