Frequently asked questions.
Auto glass service extends beyond windshields to include side windows, rear windows, sunroofs, quarter glass, and side mirrors. Power window issues may involve not just the glass but also the regulator or motor. Damaged side mirrors—especially if they’re heated or have integrated signals—may require replacement of the glass, mirror housing, or electrical components. Sunroof damage, leaks, or shattered glass panels typically require replacement due to the nature of tempered glass. Regular inspection of all glass surfaces and seals is important, especially after impacts or extreme weather, to ensure visibility, safety, and comfort.
Both OEM (Original Equipment Manufacturer) and high-quality aftermarket glass can be safe when installed correctly by a certified technician. OEM glass is made by the same manufacturer that supplied your vehicle’s original glass, ensuring a perfect fit and finish. Aftermarket glass is produced by third-party manufacturers and can vary in quality—though many meet or exceed federal safety standards. The biggest differences often come down to brand compatibility, thickness, tint matching, and cost. If you drive a newer vehicle with ADAS features, OEM glass is sometimes recommended for optimal sensor performance and proper calibration.
Windshield replacement typically takes about 60–90 minutes. The process begins with carefully removing the damaged windshield and any trim or molding. The technician will then clean and prep the mounting area, apply primer, and use a high-strength urethane adhesive to bond the new windshield in place. After installation, there’s a curing period—usually about an hour—during which the vehicle must remain stationary to ensure a proper seal. If your vehicle has ADAS (Advanced Driver Assistance Systems), such as lane departure warning or automatic braking, recalibration of the camera or sensors may be necessary, which could extend the appointment.
Most comprehensive auto insurance policies cover glass repair and replacement, but the details vary by provider and policy. Many insurers waive the deductible for windshield repairs, encouraging prompt service before small chips become large cracks. However, if a full replacement is necessary, your deductible may apply unless you have full glass coverage or a zero-deductible add-on. It’s a good idea to contact your insurance provider before scheduling service to confirm your coverage, potential out-of-pocket costs, and whether they require using preferred repair shops or allow you to choose your own.
Whether you should repair or replace your auto glass depends on several factors: the type of glass, location and size of the damage, and safety considerations. For windshields, chips smaller than a quarter and cracks less than six inches can often be repaired, especially if they’re not directly in the driver’s line of sight. Repairs preserve the original factory seal and are typically quicker and less expensive. However, side windows, rear windows, and sunroofs are usually made from tempered glass, which shatters on impact and cannot be repaired—these must be replaced. A professional technician can inspect the damage and recommend the safest and most cost-effective option.
Typically, small chips and cracks (under 6 inches) in windshields can be repaired. Side and rear windows usually require replacement due to safety concerns.
If the damage is smaller than a dollar bill, not in the driver’s line of sight, and doesn’t penetrate both layers of glass, it may be repairable.
Minor scratches can sometimes be polished, but cracks in side mirrors usually require replacement.
Sunroof glass is typically tempered and shatters when damaged, so it usually needs to be replaced, not repaired.
Windshield repairs usually take 30 minutes or less.
