Frequently Asked Questions

  • When does a windshield chip need repair versus full replacement?

    Chips smaller than a quarter and cracks under six inches typically qualify for repair if they're outside the driver's direct sightline. Damage near windshield edges, multiple impact points, or cracks that have already spread usually require full replacement because they compromise structural integrity. Acting fast on small chips prevents them from spreading into irreparable cracks.

  • What is ADAS calibration and why is it required after windshield replacement?

    ADAS calibration realigns cameras and sensors mounted on or behind the windshield that control features like lane departure warnings, adaptive cruise control, and automatic emergency braking. Windshield replacement shifts these components slightly, throwing off their accuracy. Without recalibration, your safety systems may fail to detect hazards or activate incorrectly.

  • How does mobile auto glass service work in Zebulon and surrounding areas?

    Mobile service brings all equipment, materials, and tools directly to your home, workplace, or roadside location, eliminating the need to drive with damaged glass. Technicians perform the same quality work on-site as a traditional shop, including removal, installation, and cleanup. You avoid scheduling disruptions and get your vehicle back faster without travel time.

  • Which vehicles require ADAS recalibration after glass replacement?

    Most vehicles manufactured after 2015 with driver assistance features require calibration, including popular models from Toyota, Honda, Ford, Hyundai, Tesla, Nissan, and Kia. If your vehicle has lane keep assist, forward collision warning, auto high beams, or camera-based rain sensors, the windshield houses critical sensors that need realignment after replacement.

  • What causes windshield chips to suddenly spread into cracks?

    Temperature swings cause glass to expand and contract, turning small chips into spreading cracks within hours. Road vibrations, additional impacts, or even using defrost on a chipped windshield stress the damaged area. North Carolina's temperature fluctuations between cold mornings and warm afternoons accelerate this process, especially in fall and spring.

  • How long after windshield installation can you safely drive the vehicle?

    Drive-away time depends on adhesive curing, which varies by product and weather conditions. Most installations require at least one hour of stationary curing before safe driving, while full bond strength develops over 24 hours. Humidity and temperature affect curing speed—installers provide specific wait times based on conditions during your service.

  • What happens during door glass replacement for a broken side window?

    Technicians remove broken glass, vacuum interior debris, disconnect window regulator components, and install new glass into the door frame. The process includes testing window operation, ensuring proper seal against weather stripping, and verifying alignment with the door frame. For break-ins, this also restores vehicle security and protects your interior from weather exposure.

  • Why does auto glass replacement cost vary between different vehicles?

    Glass shape complexity, embedded technology like heating elements or antennas, and OEM versus aftermarket parts affect pricing. Vehicles with ADAS sensors require calibration services on top of glass replacement. Luxury and electric vehicles like Tesla often use specialized glass with unique specifications that cost more than standard automotive glass.

  • Can you repair a windshield chip that's directly in the driver's line of sight?

    Repairs in the driver's central vision area often leave visible distortion even after successful bonding, which creates safety concerns and may not pass inspection. Chips located there typically require full windshield replacement to restore completely clear, undistorted visibility. Repairs work best when damage sits outside the critical viewing zone directly in front of the steering wheel.

  • What's involved in safe glass removal before windshield replacement?

    Safe removal uses specialized tools to cut through urethane adhesive without damaging the vehicle frame or pinch weld. Technicians protect interior surfaces, disconnect any embedded components like antennas or sensors, and ensure the frame remains intact for proper new glass bonding. Rushing this step risks frame damage that prevents secure installation of the replacement windshield.

  • Do you offer mobile windshield repair and replacement in Knightdale, NC, and can you help with insurance claims?

    Yes — we dispatch mobile auto glass service directly to your home, office, or any Knightdale location for windshield chip repair, full replacements, door glass, and ADAS calibration. We also work directly with most major insurance providers to handle your claim paperwork, so you don't have to. Call us to confirm coverage and schedule your appointment.

  • Does auto glass replacement in Knightdale, NC include ADAS recalibration at the same appointment?

    Yes, ADAS recalibration can be completed as part of your auto glass replacement service in Knightdale. Many modern vehicles require recalibration any time the windshield is replaced to keep safety systems like lane-keep assist and automatic braking functioning accurately, and handling it in one visit avoids a separate trip.

  • Will my auto insurance cover windshield replacement in Knightdale, NC, and do I have to manage the claim myself?

    Comprehensive auto insurance policies typically cover windshield replacement, and in many cases the work is completed with little or no out-of-pocket cost to you. We work directly with most major insurers on your behalf, so you won't need to navigate the paperwork or reimbursement process alone.

  • Does temperature change in fall affect windshield chip spreading, and can you come to my location in Zebulon or Raleigh the same day?

    Yes — cooler fall temperatures cause glass to contract, which can accelerate an existing chip into a full crack faster than you might expect. Same-day mobile service limits that damage before it spreads, and Fannin Auto Glass serves Zebulon and the broader Triangle area with on-site repairs at your home or workplace.

  • What's the best auto glass replacement service in Zebulon, NC?

    Fannin Auto Glass Service is a dedicated auto glass shop in Zebulon offering windshield repair, full replacement, and mobile service throughout the Triangle area. Their combination of fast response times, on-site convenience, and ADAS recalibration capability at the same appointment makes them a strong choice for drivers in the Zebulon area.

  • Is there a same-day mobile windshield repair option available in Zebulon, NC?

    Same-day mobile windshield repair is available in Zebulon, with Fannin Auto Glass coming directly to your home or workplace. Addressing a chip quickly — especially as fall temperatures drop — prevents thermal contraction from turning a small repair into a full replacement.

  • How quickly should I get a windshield chip repaired before it becomes a bigger problem in the Zebulon area?

    A chip should be repaired as soon as possible, ideally within a day or two of noticing it. Temperature swings common in fall around Zebulon cause glass to expand and contract, which can turn a minor chip into a crack that requires full replacement rather than a simple repair.

  • Is mobile windshield replacement from a local specialist in Zebulon cheaper than going through a national chain?

    Mobile windshield replacement from a local specialist is often more affordable than national chains and includes the same quality glass and workmanship warranty — without a trip to a shop. We come directly to your home or workplace in Zebulon and the surrounding area, and we handle insurance claims so you're not paying more out of pocket.

  • Does a local auto glass shop in Zebulon, NC offer the same insurance claim assistance and warranties as a national chain?

    Yes, a local auto glass specialist in Zebulon can handle your insurance claim from start to finish and back the work with a quality warranty, just as a national chain would. The difference is personalized service and the convenience of mobile replacement at your location instead of driving to a shop.

  • Why should I choose a local Zebulon auto glass company for windshield installation instead of a national service?

    A local Zebulon auto glass company offers the same high-quality glass, installation standards, and insurance billing as national services, often at a lower price and with faster same-day availability. You also get direct communication with the technician doing the work rather than a call center, which means quicker answers and more accountability.

  •  How can I tell if my windshield was installed correctly?

     A properly installed windshield should sit evenly within the vehicle frame, have a consistent seal, and be free from noticeable air or water leaks. Excessive wind noise, water entering during rain or a car wash, visible gaps, or glass that does not appear properly aligned can indicate an installation problem. At Fannin Auto Glass Service, proper preparation, adhesive application, alignment, and curing are important parts of the installation—not just putting new glass in the vehicle.


  • Why is my car making an air or wind noise after a windshield replacement?

     A new windshield should not create unusual wind noise. Whistling or rushing air can occur when the glass is not seated or sealed correctly, leaving a path for air to move around the windshield. If you notice new wind noise after an installation, it is worth having the seal and installation inspected rather than assuming the noise is normal.


  •  Why is water getting inside my car after a windshield replacement?

     Water entering your vehicle after a windshield replacement can be a sign of an incomplete or improper seal. The windshield must be correctly positioned and bonded to the vehicle frame to prevent water from finding a path around the glass. This is one reason proper installation matters just as much as selecting the replacement glass.


  •  Does the quality of the windshield glass matter?

     Yes. Replacement glass needs to be appropriate for your specific vehicle, including its size, shape, tint, and any features built into the glass. Some windshields may also accommodate cameras, antennas, rain sensors, or other technology. The goal is not simply to find a piece of glass that fits—it is to use the correct glass and install it properly for the vehicle.


  • What should I ask an auto glass company before agreeing to a windshield replacement?

     Ask what type of glass will be installed, whether your vehicle requires ADAS calibration, how the old glass will be removed, what adhesive will be used, how long the vehicle needs to remain stationary after installation, and what is covered by the workmanship warranty. A knowledgeable technician should be willing to explain the process rather than simply give you a price.


  • Can you tell me if my windshield really needs to be replaced?

    Yes. Not every damaged windshield needs to be replaced. The size, location, depth, and type of damage all matter. If a chip can safely be repaired, repair may be an option. If the damage compromises visibility or the structural integrity of the glass, replacement may be necessary. Fannin's goal is to determine what your vehicle actually needs rather than automatically recommending the most expensive service.


  • Why does windshield replacement involve more than removing the old glass and putting in the new glass?

     A proper replacement involves carefully removing the old glass, preparing the vehicle's bonding surface, applying the appropriate adhesive, positioning the new glass correctly, and allowing the adhesive to cure properly. On vehicles equipped with advanced safety technology, calibration may also be necessary. Each part of the process affects how the windshield performs after installation.


  • Can a bad windshield installation cause problems later?

     Yes. Problems such as water leaks, wind noise, poor fit, or issues with the vehicle's safety systems can occur when glass is not properly installed. Pre-existing rust, corrosion, previous installation problems, or damage to the vehicle's bonding surface can also affect the result. A thorough installation process helps identify potential issues before the new glass is installed.


  • What happens if my vehicle has rust or damage around the windshield frame?

     The condition of the vehicle's frame and bonding area matters before new glass is installed. Rust, corrosion, or existing structural damage can affect how well the replacement glass bonds to the vehicle. These conditions should be identified and discussed before installation so the customer understands any concerns that could affect the finished result.


  • Why should I choose an experienced auto glass technician instead of simply choosing the cheapest price?

    Auto glass replacement is more than a glass swap. The technician needs to select the correct glass, safely remove the existing glass, properly prepare the bonding surface, apply adhesive correctly, position the replacement accurately, allow the adhesive to cure, and determine whether ADAS calibration is required. A lower price may look attractive initially, but customers should also consider the quality of the materials, installation process, experience, and support they receive.
