Letting a non certified installer work on your vehicle could lead to more issues for you in the long run. Unqualified shops are typically less expensive because they cut corners and do not prep and prime vehicles properly leading to corrosion. If left untreated, the corrosion will require more work and eventually work at a body shop. Our shop only employs certified installers that are properly trained. Pictures above show corrosion, the remediation, and finally primed for new windshield install.
