Why You Should Choose a VSI Certified Siding Installer

What does VSI Certification entail?

In order to become a VSI Certified installer, contractors must complete the Vinyl Siding Institute’s Certified Installer Program. This program requires both classroom training as well as the successful completion of a written examination. During classroom training, installers are thoroughly exposed to industry-approved vinyl siding installation techniques. Anchored in the industry standard, ASTM D4756, the training program gives installers the skills and knowledge to properly install vinyl siding as well as accessories. In order to pass the program, certified installers will have proven their ability to:

  • Properly fasten siding in a way that allows siding to stay straight and secure during normal expansion and contraction.
  • Prevent water infiltration by properly preparing doors, windows, and other possible water entry points.
  • Ensure a beautiful finished product by paying attention to details.

To qualify as a VSI Certified Installer, vinyl siding contractors must possess at least 2 years of installation experience, attend the VSI Certified Vinyl Siding Institute’s Certified Installer Program, and successfully pass the VSI Certified Installer exam. To ensure that VSI-Certified Installers stay up-to-date on the latest standards and trends, all installers must be re-certified every 3 years through VSI. By hiring a VSI Certified Installer, you can be confident that your vinyl siding will be installed in congruence with all of the latest industry standards, ensuring a beautiful finished product that is meant to last.
