Common Causes Of Window Cracks
1. Stress Cracks
Stress cracks occur due to thermal stress, where rapid temperature changes cause the glass to expand or contract unevenly. T
his can happen when one part of the window is shaded while another part is exposed to direct sunlight, leading to differential heating. Stress cracks often begin at the corners of the glass and can grow if not addressed promptly.
2. Impact Breaks
Impact breaks happen when an object strikes the window and causes a sudden crack or shatter. Common culprits include sports balls, tree branches, or debris during storms.
And as any bullet hole will prove, even small objects can cause significant damage if thrown with enough force.
3. Pressure Cracks
Pressure cracks are less common but can cause serious damage, especially in insulated or double-paned windows.
These cracks form due to changes in atmospheric pressure or improper installation that restricts the natural expansion and contraction of the glass. If there isn't enough space around the window for movement, it can lead to curved cracks resembling an hourglass shape.

4. Weather-Related Damage
Severe weather conditions, such as storms, can lead to window damage from high winds, hail, or falling debris.
5. Vandalism
Intentional damage or accidental breakage from nearby activities is another cause of cracked windows
6. Installation Issues
Improper installation practices can lead to various problems, including stress cracks and misalignment that make windows more susceptible to impact damage.

When To Repair vs. Replace A Cracked Window
When to Repair a Cracked Window
- Small Cracks or Chips: If the crack is minor and does not compromise the structural integrity of the window, it may be possible to repair it. This is a cost-effective solution for single-pane windows where the glass can be replaced without extensive work.
- Frame Integrity: If the window frame is in good condition and only the glass is damaged, repairs can be a viable option.
When to Replace a Cracked Window
- Large Cracks or Multiple Damages: If the crack is extensive or there are multiple cracks, replacement is necessary as they can compromise safety and energy efficiency.
- Broken Seals: For double-paned windows, if the seal is broken due to cracks, moisture can enter between the panes, leading to fogging and further damage. In such cases, replacing the entire unit may be required.
- Energy Efficiency: Replacing old or damaged windows with new energy-efficient models can lead to significant savings on energy bills. While initially more costly than repairs, replacements often provide better long-term value.
- Outdated Appearance: If windows are outdated or have other issues like drafts or difficulty opening, replacing them can enhance both functionality and appearance.

Frequently Asked Questions (FAQs)
How do I identify the type of crack in my window?
Different cracks have distinctive patterns.
Impact cracks look like spiderwebs, stress cracks are jagged and originate from the edge, and pressure cracks are often single curved lines.
Can all cracked windows be repaired?
Not all cracked windows can be repaired.
Minor surface cracks might be fixable with the right tools and techniques. However, larger or deeper cracks require replacement for safety and efficiency.
How long does a window repair last?
The longevity of a window repair depends on the quality of the materials used and the severity of the initial damage. A well-executed repair can last several years, but it will not match the lifespan of a new window.
Is it safe to repair windows yourself?
While minor repairs can be done by anyone, always prioritize safety. Wear protective gear and use the correct tools. For extensive damage, seek professional assistance to avoid injury and get a proper fix.
