My Windshield Cracked For No Reason

Dec 4, 2017Windshield Repair, Auto Glass

You woke up this morning, went to your car in the garage to go to work, and discovered that your windshield cracked for no reason. Or maybe you discovered your windshield cracked when you came out of a restaurant after a business dinner. You know nothing happened to it while you were inside.

The first thing to understand about windshield damage is that windshields don’t just crack. It may seem so when you discover the damage, but there is always an underlying reason.

Reasons a windshield can crack

There are some obvious reasons that a windshield cracks:

  • Flying rocks or gravel when driving
  • A rogue baseball
  • A tree branch
  • Hail

Typically, if the crack was the result of one of these reasons, you would have known about it before you discovered the crack.

It’s more likely that your windshield cracked due to one of the lesser known reasons for windshield cracks, chips, and other breakage.

Improper or poor installation

There are high standards for windshield installation, but mistakes happen. If the windshield isn’t installed properly, it could be loose, and vibrations could then cause stress fractures.

Temperature changes

Fluctuations in temperature, particularly if you use a defroster or even the car’s heater, can cause the glass to expand and contract. Because the glass heats faster around the edges, these expansions and contractions occur at different rates, and this leads to cracking.

Sunlight

Sunlight has much the same effect as temperature changes. It heats the metal near the edges faster than the middle of the windshield, and causes cracks.

Glass imperfections

Your windshield may have had a recall. Or there may have simply been a nearly invisible imperfection that you didn’t see.

Pressure changes

Pressure changes from things such as sudden high wind gusts, or even setting something heavy on the windshield, could potentially be enough to create a crack that seems to come out of nowhere. 

What to do if your windshield cracked

It’s imperative to fix a broken windshield. It may look like a minor crack that can wait, and if it doesn’t cross your field of vision, you may figure it’s not a problem. But the damage may be more serious than it appears. Even if it’s not, a crack left alone will get worse.

Windshield repair services train their staff to be able to determine whether your windshield is repairable. At Go Glass, small bullseye or half-moon, star breaks, combination breaks, and surface pit damage can often be repaired.

FAQ - Year-Round Window and Door Care

Why is seasonal home glass care important?

Seasonal home glass care helps protect windows and doors from temperature changes, moisture, and everyday wear. Regular inspections and maintenance help stop seal failure, drafts, and condensation. They also prevent costly repairs. This work improves energy efficiency and comfort all year long.

How often should windows and doors be inspected?

Windows and doors should be inspected at least twice a year, ideally in spring and fall. Seasonal inspections allow homeowners to identify cracked glass, failing seals, damaged weatherstripping, and operational issues before extreme weather causes further damage.

What are signs that window glass needs repair or replacement?

Common signs include fogging between panes, visible cracks or chips, drafts, increased energy bills, and difficulty opening or closing windows or doors. These issues often indicate seal failure or structural damage that requires professional window glass repair or replacement.

How do energy-efficient windows help during summer and winter?

Energy-efficient windows and doors regulate indoor temperatures by reducing heat transfer. In summer, they block UV rays and heat gain; in winter, they help retain warmth. This improves comfort, protects interiors, and lowers heating and cooling costs year-round.

When should I call a professional glass company instead of DIY fixes?

Professional service is recommended when dealing with cracked glass, fogged insulated units, misaligned doors, storm damage, or persistent drafts. Experts ensure proper measurements, safe installation, and long-lasting performance that DIY repairs can’t guarantee.
