Well, through the car window, we want to see the road, other users, pedestrians, signs, lights… in short, everything but the glass.

The distractions can be mechanical damage caused by bad luck – we'll discuss this more below – as well as dirt from everyday use. These can be easily dealt with.

Cracked Car Windshield – Does It Always Need to Be Replaced?

A car traveling on the road is exposed to many situations that can result in damage. Not everything can be predicted. Among these unpleasant surprises is damage to windshields (most often) caused by small stones suddenly launched from under the wheels of a passing car and striking ours like a projectile. The adage "small stone, big problem" often applies in such situations, but not always, as sometimes repairing the cracked windshield will be sufficient.

Windshield Repair or Replacement – ​​When is Which Option Better?

When a stone chip damages your windshield, there are two options: repair or replacement. Which is better? It doesn't depend on your own opinion, but on the assessment made by a specialist at a car glass repair and restoration service. Technical criteria are decisive. If the damage is minor, the glass can be repaired . If continued use of the damaged glass poses a safety risk and repairing the cracked car glass is impossible, replacement will be necessary.

What glass damage can be repaired and what requires replacement?

Small, clean chips no larger than 2 or 3 cm can usually be repaired. It's crucial that the damage isn't close to the edge of the glass, and—most importantly—that the characteristic, expanding spider vein doesn't appear. Anyone who's encountered this on a windshield knows how unstoppable it is. Therefore, if, after an inspection, a specialist determines that a cracked car windshield can be repaired, they will recommend such a service. Otherwise, if the windshield cannot be repaired, it must be replaced.

What is the process of repairing a cracked windshield?

Cracked car windshield repair is a service performed by specialized service centers. It doesn't take long, but it requires precision, appropriate knowledge, and equipment. It's somewhat similar to dentistry. The mechanic must first thoroughly clean the area to be repaired, removing all contaminants. Then, the crack is filled with polymer resin, hardened with ultraviolet light, and polished, protecting the damaged area from further deterioration. After the entire procedure, only a small, barely visible mark remains.

Windshield replacement step by step – what is worth knowing?

How do you replace a car windshield? First, you need to remove the windshield pane (if replacing the windshield) and all components attached to the windshield, such as seals, wipers, mirrors, cameras, and sensors. The interior of the car must also be carefully protected from dirt. Then, using a special knife and suction cups, the damaged windshield is cut out and removed. The area where the windshield will be installed is cleaned of old adhesive, dirt, and degreased. The new windshield is washed and then the edges are coated with adhesive. The next step is to precisely fit the new windshield into the prepared location and secure it against movement, preferably overnight. It's best to entrust car windshield replacement to specialists . Experience helps in this task, helping to avoid unpleasant surprises that always arise when doing something for the first time.

Is driving with a cracked windshield safe and legal?

Road traffic regulations don't specify precisely what types of damage to a car's windshield precludes its use; they merely stipulate that the vehicle must be roadworthy and not pose a hazard to others . Therefore, driving with a damaged windshield is only permitted if the crack or chip doesn't pose a hazard to the vehicle's occupants or other road users. This rule applies particularly to the windshield and the driver's field of vision. During a roadside inspection, if traffic police officers determine the damage is significant, they may fine the driver up to 500 PLN and confiscate their driver's license.
