Windshield Repair vs. Replacement: Which Do You Need?

The most common question we get: do I need a full replacement, or can this be repaired? Here's how we decide.

When a Repair Works

A chip or crack can be repaired if it meets all of these:

• Smaller than about 6 inches (roughly the size of a dollar bill)
• Not in the driver's direct line of sight (roughly a 12-inch wide zone in front of the steering wheel)
• Not at the edge of the glass
• Only through the outer layer of glass (not both layers)

Chips that qualify can be fixed in about 30 minutes with a resin injection that seals the chip and prevents spreading. The repair is nearly invisible and is usually covered by insurance at zero cost to you.

When You Need Replacement

Replacement is necessary when:

• The crack is longer than 6 inches
• The damage is in the driver's line of sight
• The chip has spread into a crack that runs to the edge
• The damage penetrates both glass layers
• There are multiple chips close together

When in Doubt, Call Us

We assess on arrival and give you a straight recommendation. We never push a replacement when a repair will hold — repairs are faster, cheaper, and often covered at $0. Call (715) 396-1720 and describe the damage; we can often tell you over the phone which way it'll go.

Types of Windshield Damage — What's Repairable

The type of chip or crack matters as much as the size:

• Bullseye chip — Circular impact with a dark center. Usually repairable if under 1 inch in diameter.
• Star break — Impact point with cracks radiating outward. Repairable if under about 3 inches across and the legs haven't reached the glass edge.
• Half-moon — Crescent-shaped impact. Typically repairable.
• Crack — A line in the glass with no clear impact point. Repairable if under 6 inches and not at the edge; replacement if longer.
• Combination break — Impact point with both a bullseye and radiating legs. May be repairable depending on total size.
• Edge crack — Any crack that starts at or runs to the edge of the glass. Almost always requires replacement — edge cracks compromise the windshield's structural integrity.

What Happens If You Wait?

A chip that's repairable today can become a full replacement job in 24–48 hours. Two things accelerate spreading:

• Temperature swings — Missouri summers and cold winters put stress on glass. A chip in July heat or after an overnight freeze is much more likely to crack overnight.
• Driving vibration — Highway driving, potholes, and railroad crossings flex the windshield and can propagate a small chip into a long crack within a single trip.

If you have a chip today, getting it assessed costs nothing. Call (715) 396-1720 and we'll tell you in 30 seconds whether it's a repair or a replacement situation.

Cost Comparison: Repair vs. Replacement

Repair is always cheaper — and with comprehensive insurance, both options are typically $0. Without insurance:

• Chip or crack repair: $50–$100
• Full windshield replacement: $200–$600 depending on the vehicle
• Replacement on a vehicle with ADAS camera: $400–$800 including calibration

Insurance: Repair vs. Replacement Coverage

For chip repairs, most Missouri comprehensive policies waive the deductible entirely — insurers prefer a $75 repair over a $400 replacement, so they cover repairs at $0 even when your standard deductible is $500. For full replacements, your comprehensive deductible applies unless your policy has a separate glass provision. We verify coverage for both scenarios before starting.
