What you can do about a windshield chip right now

A windshield chip smaller than a quarter can often be repaired without replacing the entire glass, and the sooner you address it, the better your chances of stopping it from spreading into a crack. Most chips can be filled with a clear resin that hardens and bonds the glass back together. You have three main routes: do the repair yourself with a kit from an auto parts store, take the car to a glass shop for a professional repair, or contact your insurance company to see if they cover the cost.

The key difference between these routes is cost and durability. A DIY kit costs $10 to $20 and takes 30 minutes but may not last as long as a professional repair. A glass shop repair costs $50 to $150 and typically comes with a warranty. Insurance may cover it fully or partially depending on your policy, though you may have a deductible to pay first.

Key Takeaways

  • Windshield chips smaller than a quarter can be repaired with resin rather than requiring full glass replacement.
  • DIY repair kits are inexpensive but require you to follow the instructions exactly, including letting the resin cure for the full time stated on the package.
  • Professional glass shops can repair chips in under an hour and often warranty their work, but cost more than a kit.
  • Your auto insurance may cover windshield repairs in full or with a deductible, so check your policy before paying out of pocket.
  • Chips larger than a quarter or cracks longer than a few inches typically cannot be repaired and require windshield replacement.

Assess whether your chip can be repaired

Before you buy a kit or call a shop, determine the size and location of the damage. Chips smaller than a quarter inch across can almost always be repaired. Chips between a quarter and a half inch may be repairable depending on the depth and whether the damage is in the driver's line of sight. Chips larger than a half inch or any damage that has already started to crack outward will likely need a full windshield replacement instead.

Location matters too. A chip directly in the driver's line of sight—the area straight ahead that you look through most—may not be repairable even if it is small, because the repair can leave a slight cloudiness or distortion. A chip at the edge of the windshield or in the passenger's view area is easier to repair without affecting your ability to see the road.

If the chip is in the driver's line of sight and larger than a quarter inch, or if you see cracks radiating outward from the chip, contact a glass shop or your insurance company. A full replacement is safer than attempting a repair that may fail.

Check your insurance coverage before paying

Many auto insurance policies cover windshield damage under comprehensive coverage, which protects against things you cannot control—weather, road debris, vandalism. Call your insurance company or log into your online account to check whether your policy includes glass coverage and what your deductible is.

Some insurers waive the deductible for glass repairs, meaning you pay nothing out of pocket. Others require you to pay the deductible but cover the rest. A few policies do not cover glass at all. Knowing this before you pay for a repair can save you money.

If your insurance covers it, ask whether you can choose your own glass shop or whether they have preferred providers. Many insurers have a network of shops they work with regularly and may steer you toward those, but you often have the right to go elsewhere—you may just pay more of the cost yourself.

Do a DIY repair with a windshield chip kit

A windshield repair kit contains a small bottle of clear resin, an applicator tool, and instructions. Kits are sold at auto parts stores, big-box retailers, and online. Popular brands include Permatex, Safelite, and 3M, though the process is similar across all of them.

Step 1: Clean the chip. Use a small brush or compressed air to remove any dirt, dust, or loose glass from inside the chip. Wipe the area around the chip with a clean, dry cloth. Do not use water or cleaning fluid—the area must be completely dry.

Step 2: explore the resin. Follow the kit instructions exactly. Most kits have you inject resin into the chip using a syringe or applicator bottle. Fill the chip until the resin is level with the glass surface or slightly raised, depending on what the kit says. Do not overfill.

Step 3: Let it cure. This is the most important step and the one most people rush. Curing times vary by kit—some take 24 hours, others take 48 hours or more. Do not drive the car, do not expose the windshield to direct sunlight, and do not touch the repair during this time. The resin needs to harden completely or it will not bond properly and the chip will reappear.

Step 4: Remove excess resin. Once the resin has cured fully, use a plastic scraper or old credit card to gently remove any excess resin that hardened above the glass surface. Wipe the area clean with a soft cloth.

A DIY repair usually holds for several years if done correctly, but it is not as durable as a professional repair. If the chip is in a high-stress area—near the edge of the windshield or where the glass flexes—it may fail sooner.

Get a professional repair at a glass shop

A professional windshield repair takes 30 to 60 minutes and costs between $50 and $150 depending on the size of the chip and your location. The technician will clean the chip, inject a specialized resin under pressure, and cure it with UV light. The result is stronger and more durable than a DIY repair because the resin is injected deeper into the glass and cured more thoroughly.

To find a glass shop, search online for "windshield repair near me" or ask your insurance company for a referral. Many shops offer mobile service—they come to your home or workplace and do the repair in your driveway. Call ahead to confirm they can repair your specific chip and to ask about wait times.

Most professional repairs come with a warranty, usually one to three years. If the repair fails during that time, the shop will redo it for free. Ask about the warranty before you pay, and keep your receipt.

Understand when you need a full windshield replacement

If the chip is larger than a half inch, if cracks have spread outward, or if the damage is in the driver's line of sight and cannot be safely repaired, you will need a full windshield replacement. Replacement costs vary widely—typically $200 to $500 for a standard vehicle, more for luxury cars or vehicles with advanced sensors in the windshield.

Insurance usually covers windshield replacement under comprehensive coverage, though you may have a deductible. Some insurers offer zero-deductible glass coverage as an add-on, so check whether yours does. If you do not have comprehensive coverage, you will pay the full cost yourself.

A replacement takes one to two hours at a glass shop. The technician removes the old windshield, cleans the frame, installs a new windshield, and applies a sealant that must cure for several hours before you drive. Many shops recommend waiting 24 hours before driving to allow the sealant to set completely.

Prevent chips from spreading while you wait for repair

Once a chip forms, it can spread into a crack if the windshield flexes or if the temperature changes rapidly. While you are waiting for a repair appointment, take steps to slow the spread.

Avoid driving on rough roads or over potholes, which cause the windshield to flex. Do not slam car doors or close the trunk hard. Avoid sudden temperature changes—do not blast the defroster on high heat in winter or park in direct sun and then drive into shade. If you must drive, go slowly and take smooth routes.

Some people explore clear tape over the chip to prevent dirt from getting inside, though this is a temporary measure only and does not stop the chip from spreading. If the chip is on the passenger side or edge, covering it with tape is harmless. If it is in your line of sight, do not—tape will distort your view more than the chip itself.

Frequently Asked Questions

Can a chip turn into a crack if I do not repair it?

Yes. A chip is a break in the glass surface, but the glass underneath is still intact. Over time, temperature changes, road vibration, and flexing of the windshield can cause the chip to spread downward and outward into a crack. Once a crack forms, repair is no longer possible and you will need replacement.

Will a DIY kit repair last as long as a professional repair?

Usually not. A professional repair uses industrial-grade resin injected under pressure and cured with UV light, which bonds more deeply into the glass. A DIY kit uses a thinner resin that cures on its own. Both can last several years, but a professional repair is more likely to last five years or longer without failing.

Do I have to use my insurance company's preferred glass shop?

No, but using a preferred shop usually means you pay less or nothing out of pocket. If you choose a shop outside the network, you may have to pay the full cost upfront and then file a claim for reimbursement. Call your insurer to confirm their policy before scheduling a repair.

What if the chip is right at the edge of the windshield?

Edge chips are harder to repair because the glass is thinner there and the resin may not bond as well. Some shops will still repair an edge chip if it is small, but others will recommend replacement. Ask a glass shop to assess it before you decide—they can tell you whether repair is likely to hold.

How long does it take for a DIY repair to cure?

Curing time depends on the kit, but most require 24 to 48 hours. Some kits cure faster if you expose them to sunlight or UV light. Read the instructions on your specific kit and do not drive the car until the full curing time has passed, even if the resin looks hard to the touch.
