The windscreen is an important part of car safety, and even the slightest damage can affect its durability. But how do you know if a simple repair is enough or if you need to replace the windscreen altogether? At InCar, we are experts in assessing which solution best serves safety and cost-effectiveness. In this guide, we’ll go over when a windscreen can be repaired and when it needs to be replaced.
1. Vaurion sijainti – onko se kuljettajan näkökentässä?
A large pebble or crack in the windscreen field of vision is a safety hazard. They will be subject to a repair warning when the car is inspected, and a crack in the driver’s field of vision can lead to a disqualification . Tuulilasin halkeamia ei yleensä korjata, vaan windscreen replacement is often the best option. Even if a chip or crack in the glass is not directly in the driver’s field of vision, it is still worth having it repaired. The windscreen is part of the load-bearing body structure of today’s cars, and damage to the glass weakens it. It is not recommended to repair a pebble crack in the driver’s field of vision, as it may cause disturbing optical refraction defects in the windscreen, which can impair visibility and compromise driving safety. At InCar, we are committed to safety, and in such cases we recommend glass replacement.
2. Size and depth of the damage
Small stone chips can often be effectively repaired. The repair involves filling the damage with a special resin that restores the original strength of the glass and prevents the damage from spreading. If the damage is less than 2.5 cm in diameter , about the size of a 2 euro coin, it can usually be repaired, but larger cracks will require glass replacement. At InCar, we always carefully check the size and structure of the damage to ensure that the repair is a safe and long-lasting solution.
3. Location of the damage on the edge of the glass
When the damage is close to the edge of the windscreen, the crack or fissure is more susceptible to propagation and crack exacerbation. Damage at the edge also affects the glass’s adhesion and resistance to impact. In such cases, replacement is usually recommended. InCar professionals will assess the location of the damage and make a recommendation to ensure the safety of your car.
4. Impact of temperature and weather conditions
Weather conditions can affect how quickly the glass damage expands. For example, large temperature fluctuations, such as the contrast between indoor and outdoor temperatures in winter, can quickly exacerbate a crack. If the damage occurs during the winter months, it may be more sensible to carry out the replacement as soon as it occurs.
5. Age and value of the car
In the case of newer cars or cars with special equipment integrated in the windscreen, such as rain sensors, windscreen cameras or a heated windscreen, replacement may be necessary due to technical requirements. The value of the car and its impact on the resale price may also influence the decision to replace the windscreen. InCar’s experts are familiar with the requirements of modern cars and will ensure that the replacement or repair is carried out taking into account the technical characteristics of the car.
When to repair, when to replace?
Generally speaking, minor damage outside the driver’s field of vision can be repaired quickly and cheaply, while more extensive or critical damage requires replacement. Repair is a quicker and more cost-effective solution, but is not suitable for all situations.
