Saves you money
Whenever you notice a crack on your glass, it doesn’t matter how small it is. The first thing you should do is to repair it, most of us assume repairing because they do not want to spend money they take it as a minor issue, it could be minor at the moment, but with time the crack will spread and become big, and you will be forced to replace it, replacing the glass is much more expensive than repairing it because you will need to purchase the entire glass and hire a professional to fix it.
Takes little time
Repairing glass is much faster as compared to replacing. Imagine if your car glass window has cracked and you want to rush somewhere for business or something else, you’d prefer repairing the glass rather than replacing it because it saves you a lot of time.
Assuming a cracked window can be dangerous, for instance, at home or even in a car. Someone might touch the broken glass by mistake, and the entire glass breaks down, causing serious injuries. Apart from that, ignoring a crack for a while can weaken the glass over time. To avoid all this, just repair the mess in time.
