I had an extremely small crack on my windshield last year, and one day I came outside and the crack had spread to a 3 foot crack. So I got the windshield replaced and I did have to pay the deductible, but it was better than paying over $1,000 myself for a new windhsield. I asked about having the company come to my house or where I work, but they would only do it in their shop because of the rain-sensing windshield.
