Often, there is not a clear cut decision between windshield repair and replacement. But here are some of the things to consider when you're choosing between the two.

How Bad Is the Crack?

Looking at the severity of the crack can help you get an idea of whether a repair or replacement is needed, although it's no absolute determiner.

Auto glass repair can be a good choice when the crack is small. The auto glass technician will sand down the rough edges of the crack or pit and inject a resin to fill the space. The process works best when the coverage area is small, since it has a better chance of holding the crack together.

A windshield replacement is a better idea if the crack is more than a few inches wide. There are also certain types of cracks that make a window weak. If the crack touches multiple edges of the windshield, the whole window should be replaced; that piece is likely to fall out at some point. If there are multiple cracks that touch each other, this is also a sign the windshield should be replaced.

But sometimes, even small cracks should be replaced with a new windshield. If you're most concerned about not having to deal with the window again, get it replaced. There are few guarantees when it comes to glue repairs, even when the quality of the repair is high.

What Does Your Insurance Say?

Your insurance also has a voice in the decision. Sometimes, they will only pay for a full replacement rather than a repair. Of course, it's up to you whether you want to use your insurance at all. Unless your auto insurance has a $0 deductible for auto glass repair or replacement, the cost of the repairs might be less than your deductible.

What Policies Does the Auto Glass Company Offer?

Finally, speak with your auto glass repair shop, like Cambridge Collision & Auto Center, before making a decision. They might offer a policy that guarantees their repair services. For instance, they might say that if the glass breaks or continues to crack after a repair, they will apply the costs of their repair to a new windshield. In that case, you don't have a lot to lose by trying out the simpler fix first. If it doesn't work, then you will simply need to pay a bit more to get an auto glass replacement in the end.
