As you prepare to reach your destination, the layer of frost compromising your vision is just sheer enough for you to notice a small crack in your windshield. While the brisque weather spends hours freezing its surroundings, you, however, don’t have that kind of patience. Most drivers will resort to quickly blasting hot air to defrost their windshield.

3 Reasons Windshield Cracks Spread

Many drivers are left wondering how a chip the size of a dime has suddenly spread across their entire windshield, leaving them no choice but to seek replacement services.

Cold Temperatures

Basic laws of science explain how glass expands when it’s heated, and contracts when it’s cooled. In colder temperatures, windshield cracks undergo an immense amount of pressure, and it is highly probable that they will spread if they are not treated quickly.

Temperature Changes

We are all guilty of blasting our defroster to gain visibility through our windshield. However, when there is a noticeable crack or chip, exposing the cold windshield to hot temperatures can further extend the damage. Similarly, cooling down interior temperatures with a powerful air conditioner can also put pressure on a windshield, causing cracks to worsen.


The moment your windshield is presented with a chip or crack, it’s susceptible to moisture buildup. If temperatures drop once moisture gets trapped inside the crack, it can freeze and expand, causing the crack to spread. To make matters worse, it can also generate new cracks.


If your windshield is eligible for auto glass repair in Princeton, NJ, you were likely able to catch any visible chips and cracks in their early stages. In most cases, cracks that surpass the length of a dollar bill will require complete windshield replacement services.
