Are auto glass technicians certified
Auto glass work is skilled trade work, and recognized certifications show that a technician has been trained on the procedures that matter. A windshield replacement is structural — the bond supports the roof and backs the airbag — and a chip repair depends on resin technique, so the training behind the installer affects how the job holds up over time.
Skyview’s technicians are NWRD-certified for windshield repair, DINITROL-certified for glass replacement, and ASE-certified. Ask any shop what certifications its installers hold, and see our certifications page for what each one covers.

Common myths about glass certifications
Any installer can replace a windshield safely.

Certifications are just paperwork.
NWRD, DINITROL and ASE each cover a real procedure — resin repair, structural adhesive bonding, and general automotive service. A certified technician has been trained on the steps that affect how the job holds up.
