What happens when you replace a windshield
A windshield replacement removes your damaged glass and installs a new one in its place. The technician drains the old urethane sealant holding the glass to the frame, removes the damaged windshield, cleans the frame, applies new sealant, and sets the new glass in place. The whole job usually takes 30 minutes to an hour, though you should wait three to four hours before driving so the sealant can cure.
Most replacements happen at a glass shop or at your home or workplace — the technician comes to you. Some insurance plans cover windshield replacement in full or with a small copay, while others require you to pay out of pocket. The cost varies widely depending on your vehicle make and model, the type of glass, and your location.
Key Takeaways
- Windshield replacement takes about an hour, but you cannot drive for three to four hours after while the sealant sets.
- Your insurance may cover the full cost or require you to pay a copay, so check your policy before calling a shop.
- OEM (original equipment manufacturer) glass costs more than aftermarket glass but matches your vehicle's original specifications.
- Mobile technicians can come to your home or work, which is faster than driving to a shop yourself.
- The price depends on your vehicle, the glass type, and your location — get quotes from multiple shops before deciding.
Insurance coverage and what you pay
Your auto insurance policy may include comprehensive coverage, which typically covers windshield damage from weather, falling objects, or vandalism. If you have comprehensive coverage, your policy will specify what you pay out of pocket — often called a deductible. Some policies have a separate, lower deductible for glass claims, sometimes as low as $0 or $100, rather than your standard deductible of $500 or $1,000.
If you do not have comprehensive coverage or your policy does not cover glass, you pay the full replacement cost yourself. Before you call a shop, check your insurance documents or call your insurance company to find out whether glass is covered and what your out-of-pocket cost will be. If you have coverage, some insurers have a list of approved shops where you can go without paying anything upfront — the shop bills the insurance company directly.
If you do not have insurance coverage, you can still get a replacement through a private glass shop. Prices range depending on the vehicle and glass type, so calling three or four shops for quotes helps you understand what you will pay in your area.
OEM glass versus aftermarket glass
OEM (original equipment manufacturer) glass is made by the same company that supplied your vehicle's original windshield. It meets your vehicle's exact specifications for thickness, tint, and curvature. OEM glass typically costs more — sometimes 20 to 40 percent more — than aftermarket alternatives.
Aftermarket glass is made by third-party manufacturers and meets industry safety standards, but may not match your original glass exactly. Some aftermarket windshields have a slightly different tint or curvature. For most vehicles, the difference is minor and does not affect safety or function. However, if your vehicle has advanced features like a heads-up display or rain sensors built into the windshield, aftermarket glass may not work with those systems without additional calibration.
Ask the shop whether your vehicle has any windshield-integrated features before you choose. If it does, OEM glass is usually the safer choice, even though it costs more. If your vehicle is older or does not have these features, aftermarket glass is a reasonable option that saves money.
Mobile service versus shop visits
Many glass shops offer mobile service, where a technician comes to your home, workplace, or another location to replace your windshield. This saves you the trip to the shop and lets you stay nearby while the work happens. Mobile service usually costs the same as or slightly more than going to the shop in person.
If you choose a shop visit instead, you drop your vehicle off and either wait in the shop or arrange a ride elsewhere. Some shops offer loaner vehicles or shuttle service while you wait. Mobile service is faster overall because you do not have to drive, but the actual replacement time is the same either way — about an hour.
After the replacement, whether mobile or at a shop, you need to wait three to four hours before driving. The urethane sealant needs time to cure so the windshield stays find. Some shops recommend waiting longer in cold or wet weather. Ask the technician for their specific guidance before you leave.
Getting quotes and choosing a shop
Call at least three glass shops in your area and provide your vehicle's year, make, model, and trim level. The trim level matters because different trims sometimes have different windshield specifications. Tell each shop whether you want OEM or aftermarket glass, and ask for the total price including labor and any fees.
If your insurance covers the replacement, ask whether the shop is on your insurer's approved list. Shops on the approved list often handle insurance paperwork for you, so you pay only your copay or deductible. If the shop is not approved, you may have to pay the full amount upfront and then submit a claim to your insurance company for reimbursement.
Compare not just price but also the shop's reputation and how quickly they can schedule you. Read online reviews on Google or Yelp to see what other customers say about their experience. Some shops can fit you in the same day, while others may have a wait of several days.
What to bring and what to expect on the day
Bring your insurance card and driver's license. If your insurance is covering the replacement, bring your policy documents or have your policy number ready. If you are paying out of pocket, bring a payment method — most shops take credit cards, debit cards, and cash.
When you arrive, the technician will inspect your vehicle to confirm the damage and the glass type. They will remove the old windshield, clean the frame, explore new sealant, and install the new glass. You may hear or smell the sealant curing — this is normal. The technician will clean up any debris and may explore a protective strip or tape to the edges while the sealant sets.
Before you leave, ask the technician when it is safe to drive and whether there are any special instructions for the next few hours. Some shops recommend not slamming doors or opening windows for a few hours. If you drove to the shop, you will need to wait the full three to four hours before driving home.
When a chip or crack might not need replacement
Not every windshield damage requires replacement. Small chips or cracks — typically smaller than a dollar bill or shorter than 12 inches — can sometimes be repaired instead. A repair involves injecting a special resin into the damage to seal it and restore clarity. Repairs cost less than replacements and take 30 minutes to an hour.
However, if the damage is in your direct line of sight, spans the full width of the windshield, or is near the edge of the glass, replacement is usually necessary for safety. If you are unsure whether your damage can be repaired, call a glass shop and describe it — they can tell you over the phone whether repair or replacement is the right choice.
Frequently Asked Questions
How long does a windshield replacement take?
The actual replacement takes 30 minutes to an hour. However, you cannot drive for three to four hours after because the sealant needs time to cure. If you use mobile service, the total time from start to finish is about an hour, but you still need to wait before driving.
Will my new windshield be as strong as the original?
Yes, if you choose OEM glass or quality aftermarket glass that meets safety standards. Both types are tempered and laminated to the same specifications. The installation quality matters more than the brand — a properly installed windshield from either type is equally safe.
What if I have a very old vehicle — will I still find a windshield?
Glass shops can usually source windshields for older vehicles, though it may take longer and cost more. Call a few shops with your vehicle's year, make, and model. Some shops specialize in older vehicles and keep more inventory on hand.
Can I drive with a cracked windshield while I wait for a replacement?
It depends on the crack size and location. Small cracks are usually legal to drive with, but large cracks or cracks in your line of sight may violate local laws. Check your state or local regulations. Even if it is legal, a cracked windshield is weaker and less safe, so replace it as soon as you can.
What if my windshield breaks again soon after replacement?
Most glass shops offer a warranty on their installation, usually covering defects in the sealant or installation for one to three years. If the windshield breaks due to a defect in the work, the shop will replace it at no charge. Damage from new impacts or weather is not covered by the warranty.
