Does Missouri require a state license for windshield replacement?
Missouri has no statewide auto-glass technician license for windshield replacement. Hiring should focus on the shop's credentials, insurance and safety standards instead. Businesses that specialize solely in glass replacement are not required to hold an auto body repair facility license.
Why does AGSC certification matter?
The Auto Glass Safety Council's AGRSS standard is the main industry safety benchmark for windshield replacement. It is intended to protect retention-system integrity in crash scenarios. AGSC-certified shops say they follow OEM standards for structural windshield bonding and ADAS recalibration.
What technician credentials are a strong signal?
ASE certifications are valid for 5 years and must be retested to renew. Current ASE collision-repair credentials are a stronger signal than a general claim of experience. A technician with current B2, B3, B4 and B5 certifications earns Master Collision Repair and Refinish Technician status.
How should weather affect the timing of my replacement?
Kansas City hail season commonly runs from roughly March through June, peaking in late spring. The city also sees precipitation on about 98 days per year. Ask whether the shop offers quick scheduling and mobile service, and whether it has an indoor work space for curing.
What to do next
- Ask the pro for proof of insurance and confirm the shop is established, not an unverified installer.
- Verify AGSC certification or confirm the shop follows the AGRSS standard before you book.
- Ask the pro for the safe drive-away time in writing, such as the 60 minutes cited for fast-cure adhesive.
- Compare written quotes against the typical national range of about $300 to $650 per window.
