Is Your Double Pane Window Cracked on the Inside? Here’s What to Do.

July 17, 2020

Few things make homeowners worry quite as much as the issue of a double pane window cracked on the inside. Fortunately, a cracked window pane doesn’t have to result in a budget disaster. Read on for expert tips on how you can affordably repair a window.

Causes of Window Pane Cracks

There’s no denying that finding a cracked window pane is no fun. It’s especially frustrating when the problem occurs in a relatively new window. Nonetheless, any window glass can break under the right conditions.

Common reasons that the inside glass on a double pane window might develop a crack include:

  • Thermal Stress Crack
  • Pressure Crack

Pella notes, for example, that an interior window pane is subject to pressure cracks. Many of these cracks occur as a result of installation mistakes. If the window insulation doesn’t match the elevation level, the pressure can cause the glass to break.

Unfortunately, thermal stress cracks are not a rare thing. Extreme temperature fluctuations cause the glass to expand and contract. We often see tiny cracks appear when a cold spell turns into hot weather.

Knowing why your window has a crack is vital to avoid future trouble. In the meantime, you still need to repair the existing crack. Read below for advice on how to fix a cracked window pane.

Help for a Double Pane Window That is Cracked on the Inside

The troublesome thing about window cracks is that they don’t usually remain small. A tiny break can evolve into a nasty spider web of cracks over time. Here’s what you can do to fix a crack before it reaches a crisis point.

Call a Professional

The essential thing to know right away is that double pane windows rely on an air-tight seal. If the seal breaks, the window won’t function correctly. The result is that you can’t simply replace the cracked glass with a new pane.

Window manufacturers, like Pella, recommend that you forget about a DIY repair solution. To keep the window working efficiently, you must replace both panes of glass.

You’ll ultimately need to call a professional glass repair expert. Kryger Glass can repair and replace double pane windows at affordable rates. We suggest that you give a residential glass repair company a call as soon as the crack appears to avoid substantial damage.

Temporary Fix

If a repair service isn’t immediately available, there are temporary fixes to protect your home. Examples of things that you can try include:

  • Cover a small crack with packing tape
  • Tape a piece of a plastic bag on top of the crack
  • Fill the crack with clear nail polish

The above techniques only work if the crack is relatively small. If the window pane has an unstable fissure, consider covering the window with plywood. You can also protect the area from nasty weather by covering the window with a large trash bag.

Don’t forget that when you have a double pane window cracked on the inside, you need to call a professional service. 

Last Thoughts

Lastly, there’s no doubt that a double pane window cracked on the inside needs repair. Cracks worsen over time, and the best time to fix a break is when it first appears.
