Rock chip repair cost

The rock-chip repair is one of the highest-value services in the auto-glass business. A chip the size of a dime gets fixed in about 30 minutes for under $150 — and that's usually fully covered by your insurance. Here's what to expect on pricing and why acting fast is the difference between a $100 repair and a $400 replacement.

Typical pricing

In the Kansas City metro:

• Single chip repair: $80–$150
• Each additional chip on the same windshield: +$25
• Short crack repair (under 6"): $110–$180
• Mobile service surcharge: +$25–$45

Most shops include a 1-year warranty: if the repair fails and you need a replacement within a year, the repair fee credits toward the new windshield.

Why repair is much less expensive than replacement

A repair takes one tech, no glass inventory, no calibration, and 30 minutes. A replacement takes one or two techs, $200+ of glass, often $200+ of calibration equipment time, and 2-3 hours including cure time. The materials cost for a repair is essentially a syringe of UV-cured resin and the labor is brief.

Insurance companies do the math too — that's why most comprehensive policies cover chip repair at $0 deductible. A $100 repair claim today prevents a $500 replacement claim six months from now after the chip spreads.

What insurance pays

If you have comprehensive auto coverage:

• $0 glass-coverage rider: repair is fully covered, you pay nothing.
• Standard deductible $100+: usually the repair is still covered at $0 because most insurers explicitly waive the deductible for chip repair (they want to avoid a future replacement claim).

Filing a no-fault glass claim in Kansas or Missouri does not typically raise your rate. See does insurance cover windshield replacement.

Why act fast

Glass expands and contracts with temperature. A chip that's stable at 70°F can spread overnight when temperatures swing 30 degrees and you crank the defroster on the way to work. KC weather, especially in spring and fall, is a chip's worst enemy.

Other things that can rapidly worsen a chip:

• Hot water on a cold windshield (sudden thermal shock)
• Slamming a door (pressure wave through the cabin)
• Driving over potholes or speed bumps (flex in the body)
• Pressure washing the windshield directly

If you have a chip today, get it scheduled this week. Don't put it off.

What the repair actually does (and doesn't)

The repair process injects UV-cured resin into the void the rock left in the outer glass layer, then cures it under UV light. It restores about 95% of the original structural strength and stops the damage from spreading.

What it won't do: make the chip completely invisible. There will be a faint discoloration roughly the size of the original chip. The repair is a structural fix, not a cosmetic one. For damage in the driver's primary line of sight, that residual scar can be distracting — most shops recommend replacement instead for driver-side chips.
