Can Cracked Window Glass Be Repaired?

Generally speaking, there are not many cases where cracked window glass can be repaired. This mainly depends on the type of crack that you have. It’s generally accepted that cracks approximately longer than an inch, double-paned glass that have holes in both panes or glass that’s broken into pieces are broken beyond repair. That means that any cracked window class smaller than that might be able to be fixed yourself. However, it’s also important to remember to repair cracked window glass as soon as possible, because small cracks can become larger in a short amount of time if they’re exposed to moisture, changes in temperature, or misuse. And while there are cracks that are small enough to be repaired yourself or by a professional, it’s important to be aware that this may only be a short-term solution depending on the damage that’s been done.

How to Temporarily Fix a Cracked Window

Repairing broken glass in a window is usually only a temporary fix. There are some simple, quick fixes you can try, but the only truly safe and permanent way to fix cracked glass is to install a replacement window. If a temporary solution is exactly what you’re looking for while on the hunt for the perfect new windows for your home, you can try one of these following fixes:

1. Masking Tape

Try applying masking tape to either side of the crack on the glass. This will keep the glass intact and prevent it from breaking further, while simultaneously keeping water from leaking through. Make sure to extend the tape past the crack on both sides, pressing it firmly into the glass for the best results.

2. Glass Adhesives

Glass adhesives that are typically advertised for use on car windshields are also an option. Thoroughly clean the break, flushing out any potential debris with an eyedropper before applying tape to the back of the crack. This will keep the adhesive from leaking out the opposite side of the window. Using a syringe or brush, apply the adhesive to the crack and allow it to dry completely before you remove the tape.

3. Thick Plastic Cover

If you’re looking for a temporary solution that will be sure to keep out any drafts and bugs, applying a thick plastic covering on top of the window crack will surely do the trick. Cut a piece of plastic that’s large enough to cover the surface area of broken glass from a shower curtain, tarp, shopping bag, or another household item made from a plastic sheet. Use duct tape to adhere to the edges of the plastic of the glass.

Simple Methods for Fixing Cracked Window Glass at Home

Up for fixing your broken window glass yourself? Everyone needs a new DIY project! Here are a few simple methods you can try.

Fixing Tape over the crack



While perhaps not the most aesthetically pleasin

While perhaps not the most aesthetically pleasing solution, using tape on a crack will typically keep it from spreading and seal it. If you go this route—by far the easiest solution—use either clear packing tape or another strong, clear adhesive tape, so that the tape does not cause a distraction.

Nail Polish or Glue



Another option is to fill the crack with either

Another option is to fill the crack with either nail polish or glue. It should go without saying that you should use clear versions of each of these. Once you sufficiently fill the crack with your solution of choice, let it dry, and then repeat the process. You may need to do this a few times to ensure the crack is completely filled and sealed.

Epoxy: gives a strongest seal with transparent look



This is the most time-intensive solution, but al

This is the most time-intensive solution, but also the best. If you are up for it, epoxy, which is a thermosetting polymer, will give you the strongest seal and the cleanest look to your windows. In fact, when done effectively, epoxy can sometimes nearly erase the existence of a crack.

This method will begin by thoroughly cleaning the window and then filling the crack with the epoxy, a process that may need to be repeated to make sure it is done thoroughly and completely. When you are done, you will need to scrape off the extra dried resin, but your window crack should be good as new!

What Kind of Cracked Glass Can You Repair?

Can Be Repaired
  • Single-pane glass

  • Mirrors

  • Glass tiles

  • Sidelites

  • Picture glass

  • Some kitchen glassware

Cannot Be Repaired Double-pane windows Microwave doors Oven doors Shower or tub glass Automotive glass

Picture glass, door glass or door sidelites, single-pane windows, mirrors, and glass tile can be repaired with the two-part epoxy method. Kitchen glassware that will not be heated can often be repaired too.

Cracked phone or tablet glass can be repaired to a limited degree. Though the crack will be visible, the fix will prevent the glass from falling out and will stop a crack from lengthening. Plus, it will smooth over the crack and reduce sharp ridges.

Round impact cracks tend to repair best if they are no more than 1-inch diameter. Long cracks should be no more than 12 inches. Glass repair will only work on single pane glass.

Do not repair microwave door glass, double-pane windows, shower or tub door glass, or automotive glass with this method.
