You’re driving north on I-405, following a gravel truck through Bothell, when you hear it — that sharp crack against the windshield. You look up and see a small chip, about the size of a dime. Your first thought is probably: Is this a big deal? Can it be fixed? How much is this going to cost me?
The good news: in most cases, a rock chip is a 20-minute, $70 fix — and if you have comprehensive insurance, it’s often completely free. The bad news: if you ignore it, that chip will almost certainly spread into a full crack, turning a $70 repair into a $200–$400 replacement.
This guide answers every question Washington drivers ask about rock chip repair — from whether your chip qualifies to what the process actually involves, how much it costs, and what happens if you wait.
If you’re searching for rock chip repair near me in Snohomish County, Joe’s Auto Glass offers same-day walk-in and mobile windshield chip repair across Everett, Bothell, Lynnwood, Marysville, Shoreline, Mukilteo, Monroe, and all surrounding areas — with windshield crack repair starting at $70 and most insurance repairs completely free.
What Exactly Is a Rock Chip?
A rock chip is a small area of damage caused by a stone, piece of gravel, or road debris striking your windshield at speed. The force of impact creates a pit or crack in the outer layer of glass.
Windshields are made of laminated glass — two layers of glass bonded together with a layer of polyvinyl butyral (PVB) plastic in between. This construction is what prevents the windshield from shattering on impact. A repairable rock chip is one where only the outer layer of glass is damaged, and the inner PVB layer remains intact.
Rock chips come in several types, each with different repairability:
- Bullseye — A circular impact crater with a clean centre. One of the easiest to repair cleanly.
- Star Break — A central impact point with short cracks radiating outward. Highly repairable if the arms are under 2 inches.
- Combination Break — A bullseye with radial cracks coming off it. Still repairable if total damage stays within the size threshold.
- Crack Chip / Ding — A single, short crack from a direct impact. Repairable if small.
- Half-Moon — A partial bullseye, often caused by a non-round object. Repairable if shallow.
The type of chip matters less than three things: size, location, and depth.
Can Your Rock Chip Be Repaired? The 3 Rules
Not every chip can be repaired — and a trustworthy auto glass shop will always tell you honestly if replacement is the right call. Here are the three factors that determine repairability:
Rule 1: Size — How Big Can a Chip Be to Repair? (The Quarter Test)
The industry standard threshold for repair is damage no larger than a quarter in diameter (roughly 1 inch). Bullseye chips that fit under a quarter are clean candidates. Star breaks with arms under 2 inches are usually repairable. Larger damage, or cracks that have already spread to several inches, typically cannot be reliably stabilised with resin.
Repairable: Chip smaller than a quarter • Star break arms under 2 inches
Needs replacement: Chip larger than a quarter • Crack over 6 inches • Multiple chips clustered together
Rule 2: Location — Where on the Windshield?
Even a small chip in the wrong location can mean replacement is the safer choice.
Driver’s line of sight: This is the zone directly in front of the driver, roughly corresponding to the area swept by the wiper blades. A chip here can be repaired, but there is a risk of minor residual cloudiness or distortion. In Washington State, any visual obstruction in this area is a safety and inspection concern. We’ll give you an honest assessment — if the repair risk isn’t worth it, we’ll tell you.
Edge damage: Chips within 2 inches of the windshield’s edge are more complicated. Edge damage can spread faster and compromise the structural seal. These usually require replacement.
Centre or passenger side: The best location for a repair. No structural concerns, no line-of-sight issues.
✅Best for repair: Centre of windshield • Passenger side • Away from edges
⚠️Assess carefully: Driver’s direct line of sight
❌Usually needs replacement: Within 2 inches of any edge
Rule 3: Depth — Has the Inner Layer Been Hit?
Windshields have three layers: outer glass, PVB interlayer, inner glass. Resin repair works by filling and bonding the outer layer only. If the chip has penetrated through to the PVB or inner glass, the structural integrity is too compromised for repair — replacement is required. A professional technician can assess depth on the spot.
What Happens If You Ignore It?
A rock chip will almost never stay small on its own.
Here’s what happens when you leave a chip unrepaired in Washington’s climate:
Temperature changes: The PNW’s wet winters and warm summers create constant expansion and contraction of the glass. Water gets into the chip, freezes, expands, and drives the crack outward. One cold night can turn a dime-sized chip into a 6-inch crack.
Road vibration: Every bump, pothole, and rough road surface vibrates the glass. That vibration puts stress on the already-weakened impact point. I-5, I-405, SR-2 near Monroe — these roads are some of the worst for turning chips into cracks.
Pressure changes: Slamming a car door, hitting the car wash, or even a gust of wind can be enough to extend a weakened crack.
Dirt contamination: The longer a chip sits open, the more dirt and moisture fill the crack. Contaminated cracks are harder to repair cleanly — the resin can’t bond properly through debris.
The bottom line: A $70 chip repaired today is almost always a better outcome than a $300 windshield replacement next month.
How to Fix a Rock Chip in Your Windshield — The Professional Process
Rock chip repair at Joe’s takes about 20 minutes. Here’s exactly what happens:
1. Assessment
The technician examines the chip under light to evaluate size, depth, type, and location. This takes 2–3 minutes and determines whether repair is possible. We never push replacement if repair is the right answer.
2. Cleaning
The chip is carefully cleaned of any loose glass fragments, dirt, and moisture. This step is critical — contamination is the main reason DIY repair kits fail.
3. Resin Injection
A specialized injection tool is positioned over the impact point and a vacuum is applied to pull any remaining air out of the crack. High-quality clear resin is then injected under pressure, filling the chip completely. The resin is formulated to match the refractive index of the glass, making the repair nearly invisible.
4. UV Curing
Once the resin fills the chip, a UV lamp is applied to cure (harden) the resin. This takes just a few minutes.
5. Polishing
The cured resin is polished flush with the glass surface. A good repair should be difficult to see and won’t distort your view.
6. Final Check
The technician inspects the repair under light from multiple angles to confirm the resin has bonded fully and the chip is sealed.
At Joe’s, we do not drill holes in your windshield.
Some shops drill into the glass before injecting resin — this weakens the surrounding glass and often makes the damage worse. Our resin injection process requires no drilling.
Total time: 20–30 minutes. No appointment needed at our Everett shop Monday to Friday, 8am–5pm.

Does Insurance Cover Rock Chip Repair?
In most cases, yes — and this is one of the most important things Washington drivers don’t know.
If you have comprehensive auto insurance (not just liability), your insurer almost certainly covers rock chip repair. Many comprehensive policies cover chip repair with no deductible at all — meaning the repair is completely free to you. The reasoning: a $70 repair now prevents a $300+ windshield replacement claim later, so insurers are motivated to cover it.

How it works at Joe’s:
You don’t call your insurer first. You call us. We contact your insurance company, confirm your coverage, and submit the claim on your behalf. You show up, we fix it, and in most cases you pay nothing.
DIY Rock Chip Repair Kits — Do They Work?
You’ve seen the $10–$20 kits at auto parts stores. Here’s the honest answer: they work in very limited circumstances, and they fail more often than they succeed.
- Lower quality resin: Consumer kits use lower-grade resin that can yellow over time, fail to bond fully, or leave the repair looking worse than the chip.
- No vacuum tool: Professional repairs use vacuum injection to pull air out of the crack before injecting resin. Without this step, air bubbles get trapped and the repair looks cloudy.
- No UV lamp: Proper curing requires a calibrated UV light. Sunlight is inconsistent and often results in an incompletely cured repair.
- Contamination risk: Without professional cleaning tools, most DIYers inject resin into a crack that still has dirt or moisture in it. The repair fails within weeks.
- No warranty: If the repair fails and the crack spreads, you’ve contaminated the chip with DIY resin, which can make a professional repair harder or impossible.
Our honest advice: The difference in outcome between a professional repair ($70, often free with insurance) and a DIY kit ($15, often a failed result) is significant. It’s not worth the risk.
How to Protect Your Windshield After Repair
Once your chip is repaired, the resin needs a short time to fully cure and settle. Here’s what to do:
- Don’t wash your car for 24 hours — especially avoid high-pressure car washes
- Leave any tape the technician applied in place for at least an hour
- Avoid extreme temperatures — don’t park in direct sun or blast the defroster on high immediately after
- The repair is permanent — once the resin is cured, it won’t re-open
The lifetime guarantee at Joe’s covers you if the repair ever fails — if the repaired chip spreads into a crack, we credit the full repair cost toward a windshield replacement.

Does insurance cover rock chip repair in Washington State?
Yes, in most cases. If you have comprehensive auto insurance, rock chip repair is usually covered with no deductible — making it completely free. We are approved by all major insurers including GEICO, State Farm, Allstate, Progressive, USAA, Farmers, and AAA. We contact your insurer, submit the claim, and handle the paperwork. You don’t need to call them.
What happens if I don’t repair my rock chip?
A chip left unrepaired will almost always spread into a larger crack, especially in Washington’s climate. Temperature swings between cold wet winters and warm summers cause chips to expand rapidly. Road vibration on high-traffic corridors like I-405, I-5, and SR-2 accelerates spreading. What starts as a $70 chip often becomes a $300+ windshield replacement within weeks.
Can any rock chip be repaired, or do some require full replacement?
Not every chip can be repaired. The key factors are size (smaller than a quarter is best), location (not at the edge or in the driver’s line of sight), and depth (outer layer only, inner PVB not penetrated). We assess every chip on the spot and give you an honest answer. If repair isn’t the right call, we’ll tell you — and give you a quote for replacement.
