How to Stop a Windshield Crack from Spreading

Windshield crack during winter drive

Have you ever been driving down the highway, minding your own business, when suddenly a flying rock smashes into your windshield? You’re glad to be safe, but you must act fast to prevent that glass chip from growing. A small chip may appear inconspicuous at first, but if left unattended, it has the potential to morph into a larger crack and compromise the structural integrity of your windshield.

Here’s a look at the hazards of cracked windshields and how to stop a windshield crack from spreading until you seek professional windshield repair:

Why a Cracked Windshield is Dangerous

Rock chips are frustrating; there’s no doubt about it. But even if your schedule is hectic, you should prioritize windshield repair. The longer you wait, the more likely the crack will spread. Dirt buildup within the crack can also make repair more difficult.

Prioritizing windshield repair, even amidst a hectic schedule, is a proactive approach to preserving the safety and longevity of your vehicle. Timely attention to rock chips not only prevents further damage but also contributes to maintaining optimal visibility while driving. By addressing the issue promptly, you not only protect your windshield but also mitigate the potential for more extensive and costly repairs down the road.

Note: If you allow a rock chip to grow into a full-fledged crack, it’s too late to repair it. Nonetheless, you should still have your windshield replaced as soon as possible.

Why you should replace cracked windshields:

  • A cracked windshield makes accidents more dangerous: The windshield contributes to the structural integrity of your vehicle. If you get into a rollover accident, the roof is more likely to cave in if there is a cracked windshield. This can increase the chances of a serious injury or fatality on the road.
  • A cracked windshield is distracting: Cracks in the glass reflect light into your eyes, which can distract or even blind you. Police officers can ticket you for driving with a cracked windshield for those reasons.
  • A cracked windshield is unattractive: Whether you plan on selling your car or not, you want it to look its best! Replacing a cracked windshield shows you take pride in the vehicle you drive.

How to Stop a Crack in the Windshield

There are a couple of methods car owners can try to stop or slow the spread of a windshield crack. Whether it’s a temporary solution to hold you over until you can schedule a repair or a more comprehensive approach to address the issue head-on, taking the time to explore these methods can contribute to the longevity and safety of your vehicle. Read about some of those approaches below.

Use a Windshield Repair Kit

Bonafide windshield repair kits are available for purchase at local hardware stores. To use one, you must be comfortable drilling a small hole into the top layer of glass with a 1/16-inch drill bit. Next, force the specialized resin from the repair kit into the hole to seal the glass, reduce stress on the windshield, and stop cracks from forming. If you do the job well, this may be the only repair you need.

By sealing the damaged area with the resin, you not only stall the progression of cracks but also enhance the windshield’s structural integrity. A well-executed repair using a quality kit may prove to be a long-lasting solution and potentially eliminate the need for more extensive and expensive windshield replacements.

Avoid Sudden Temperature Changes

Glass expands in hot weather and contracts when it gets cold. If you direct a heating vent at your chipped windshield in cold weather, this may cause the crack to spread abruptly. Then you’ll have no choice but to replace the windshield. To prevent this from happening, park your car in the shade when possible and avoid using the window defroster until you have the chip repaired.

Ultimately, being mindful of the thermal dynamics of glass and adopting simple precautions, such as parking in the shade and delaying the use of the window defroster, can contribute to the longevity of your windshield and potentially save you from the need for a premature replacement.

Schedule Windshield Repair or Replacement

Having a rock chip filled is a quick, easy, and affordable service. It’s always best to repair your windshield if you can. However, if the chip spreads longer than three inches, a repair may not be possible. Fortunately, Glass Doctor® performs repairs and replacements to make your car, truck, or SUV roadworthy once more.
