This is an important question, but a hard one. Unless you have some knowledge in this field, it is not possible to find out all by yourself whether your broken windshield needs a repair or new installation. All windscreen damages are not the same and don’t require windscreen replacement. Many can be repaired while others require car window replacement. It is for an experienced automotive glass technician to first evaluate the extent of damage to the glass and then find out what is the best route to go.
If you have a broken windshield, hire a technician quickly to assess the severity of the damage. Among other factors, the technician will mainly consider the type, size, and location of the damage to determine the best solution to the problem.
If it is a small blemish (chip) in the windshield, you should expect a repair. For windshield cracks or larger damages, a new car windshield replacement will need to be done. However, it is also possible in some cases to repair a small crack. So, let the technician take a closer look and conduct a proper inspection of the damage so that he can suggest the best windshield crack repair solution to solve the problem effectively.
For vehicle owners, what is most important is to identify damage as soon as it occurs and then seek the help of a professional. The sooner you seek help, the more affordable the solution will possibly be.
