Factors to Consider when Repairing or Replacing Your Car’s Windscreen

Chips and cracks – these are two major forms of windscreen damages. A chip is a damage in the windscreen that generally marks the point of impact by an object. On the other hand, a crack is a distinct line that usually originates from the point of impact. It can be long or short, depending on the force applied to the windscreen.

When you encounter these damages, there are only two options – either to repair or replace your damaged windscreen. With this being said, there are factors that you must consider first before deciding what kind of solution you can acquire for your windscreen.

When to repair your auto glass?


The location of the crack or chip will greatly affect the windscreen repair procedure. If the damaged part is located near or at the edge of the windscreen, there is little or no more chance of repair as the integrity of the glass might be compromised once this part is damaged.

Also, when the chip or crack is within the wiper’s coverage, where the driver’s direct line of sight is located, it is imperative to replace the old ones with new windscreens. Lastly, damages within areas of warning systems, automatic braking systems, automatic driver assistance systems, and other sensor-sensitive surfaces must require replacement as these need to perfect and clear.


The depth of the windscreen damage comes with the size of the damage. Chips and cracks with 1-inch diameter and 3-inch length are the easiest to repair. However, deeper and bigger damages (depending on the technology to be used) can be difficult to repair or need to be totally replaced.

To make things easier when it comes to decision-making, be sure to contact a windscreen expert like that of Nationwide Windscreen Services, who is most knowledgeable about windscreen repairs in Leicester. They can give you the best recommendations about damaged windscreens.


As the technology advances in the automotive industry, the size of the chips and cracks that this technology can repair also increases. The usual size of the chip to be repaired is smaller than a quarter, and the crack is up to three inches in length.

However, repair limits are specified according to the size and shapes of the damage such as bull’s eye, the half-moon shape, stress cracks, edge cracks, star breaks, and some floater cracks. Cracks are also determined whether they form a straight, curved, or wavy lines.  But, these sizes will also vary depending on the location and depth of the damage.

When to replace your damaged windscreen?

Whilst windscreen repairs are the immediate remedy for damaged windscreens, there are damages that are beyond repair, thus, a replacement is a must. But, how will you know that your windscreen is irreparable?

When safety can be compromised

When some say that driving with broken or chipped windcreens is not a problem at all – well, it is. Windscreens aren’t installed simply because it is supposed to be there to complete a car’s appearance. In fact, windscreens are placed for important reasons. They are there to protect you or at least minimise the damage an accident might give you.

During a head-on collision, modern windscreens provide more or less 45% integrity of the vehicle’s cabin whilst in a rollover, 60%. Windscreens also act as a brace for a passenger-side airbag, which will protect you during an accident.

Damage is irreparable

Most minor chips and cracks are repairable. However, there are damages that aren’t. Therefore, replacements are done to maintain the structural integrity of the vehicle. Just make sure that you consult a professional when assessing the kind of damage in your windscreen.
