Getting a crack in your window is a huge pain. It lets in cold or hot air from outside and can even leak water when it rains. So, how can you repair a cracked window? It’s actually pretty easy. If you don’t want to splurge on repair services, you can DIY the whole thing. Let Toronto’s window and glass experts tell you how.
Prepare for Repair
The first step is preparation. When you repair a cracked window, there are a few things you need.
- Dish soap and a rag
- Two-part epoxy
- Putty knife
- Toothpick or other disposable item for mixing
- Paper plate or other disposable mixing surface
- Straight razor blade
To start, clean the area around the crack with liquid dish soap and water. This will remove any oils, dust, or grime from the glass. Once clean, let the glass air dry completely. This may take some time, so cleaning your cracked window is best done ahead of time.
Now that your window is ready for repair and you’ve gathered everything you need, it’s time to apply epoxy. To repair a cracked window with epoxy, you’ll want a two-part epoxy. This can be found at a hardware store and is made to be mixed up at the time of use. One part is a hardener, so don’t mix it up until you’re ready to apply it.
Mix the epoxy with a disposable mixer, like a toothpick or popsicle stick. Make sure you follow the instructions on the packaging. Every epoxy is a little different. Then, spread the epoxy along the crack in your window with a putty knife. Press the epoxy into the crack and swipe over it from different directions to ensure the crack is filled entirely. Scrape the flat edge of the putty knife over the entire crack to scrape away any excess epoxy.
Clean Up Window
As soon as you’ve finished applying epoxy, use a flat-edged razor blade to scrape away any excess epoxy. You can do this to remove any that got onto the intact glass surrounding the area as well as any raised epoxy along the crack.
When you’ve finished scraping off the leftovers, dampen a rag with acetone and wipe down the surrounding glass to get rid of any little remnants of epoxy before it hardens. You can wipe over the repaired crack with this rag as well to ensure the surface is flat and there’s no raised epoxy left. Then, let the epoxy cure for 24 hours.
Replace a Cracked Window
While you can repair a cracked window with epoxy, it may be worthwhile to replace a cracked window instead. If you have a modern window with two panes of glass, there’s an insulating gas between the panes that does most of the insulating for that window. When the glass cracks, there’s a chance for that gas to seep out. This is especially true if the crack has been present for a while.
If your window is old and single-pane, replacing your window is definitely the right choice. Single-pane windows have no insulation, costing you money in electricity to make up for heat and cold that leak in during summer and winter.
