Windshield Chip vs. Crack – What Pasadena Drivers Should Know

If you live or work in Pasadena, you’ve probably seen your fair share of damaged windshields — whether it’s from a flying rock on the 210 Freeway, debris on Colorado Boulevard, or sudden temperature changes that cause small chips to spread. At Doctor Auto Glass, we know that understanding the difference between a chip and a crack is the first step to protecting your safety and avoiding a costly replacement.

In this guide, we’ll break down:

• How to tell a chip from a crack
• When each can be repaired vs. replaced
• Why Pasadena’s climate and roads make fast repair essential
• How our same-day service keeps you on the road without hassle

What is a Windshield Chip?
A windshield chip is a small area of damage caused by debris, often no larger than a dime. Common types include:

• Bullseye: Circular damage with a darker center, often from a stone hit.
• Star Break: Small cracks radiating from the impact point.
• Half Moon: Similar to a bullseye but with a partial circle.

In Pasadena, chips are especially common on the 210, 134, and 110 freeways where loose gravel and road debris can be kicked up by passing cars.

Why repair quickly:

• Pasadena’s hot afternoons and cool evenings can make chips expand into cracks.
• Even small chips can weaken the structural integrity of your windshield.
• Repairs are faster and cheaper than replacements — often done in under 30 minutes.

What is a Windshield Crack?
A crack is a longer line of damage, often extending several inches or more. Cracks can form instantly from an impact or slowly from a neglected chip.

Types of cracks:

• Edge Crack: Starts within 2 inches of the windshield’s edge.
• Floater Crack: Appears in the middle of the glass.
• Stress Crack: Caused by sudden temperature changes, not direct impact.

In Pasadena, stress cracks often happen after washing your car with cold water on a hot day or parking in the sun then blasting the AC.

Chip vs. Crack – Repair or Replace?

Here’s our quick Pasadena driver’s rule of thumb:
Chips smaller than a quarter: Usually repairable.

• Cracks shorter than 3 inches: Sometimes repairable, but depends on location.
• Any damage in driver’s line of sight: Replacement is safer.
• Multiple chips or long cracks: Replacement recommended.

Why Timing is Critical in Pasadena

Delaying repairs here comes with extra risks:

1. Heat expansion: Hot Pasadena afternoons can cause glass to expand, worsening damage.
2. Urban driving: Bumpy streets and frequent stops put extra stress on the glass.
3. Seasonal weather: Winter mornings in the 40s, afternoons in the 70s — the temperature swing accelerates crack growth.
