The Advantages of Choosing a VSI Certified Contractor


If you’re thinking about installing new vinyl siding on your home, consider the advantages of choosing a VSI certified contractor to do the job. The VSI (Vinyl Siding Institute) certification shows the contractor has made the effort to educate themselves on the latest industry standard practices, and the contractor demonstrated their knowledge of these practices in a certification examination. Choosing a contractor that has VSI certification is an assurance of quality. Learn more about why you should choose a VSI certified vinyl siding contractor in our blog.


Why You Should Choose a VSI Certified Siding Contractor

Getting VSI certification is an intensive process. Contractors receive in-class training and have years of experience in proper vinyl siding installation practices. Contractors must pass a written test given by a VSI Certified Trainer in order to obtain certification. Below are some of the skills contractors are trained in:

  • Contractors must know how to fasten siding while taking into account the normal expansion and contraction that occurs due to changes in temperature throughout the year. This ensures the siding will remain straight and securely attached to the wall.
  • Contractors must know how to prepare the areas around openings such as doors or windows to prevent water from getting in and causing water damage.
  • Contractors must know how to pay attention to details to give your home a beautiful and durable appearance.

Once a contractor has obtained VSI certification, they must get re-certified in order to maintain their certification. They must apply for re-certification once after their first two years, and then every three years after that. This is to ensure that the contractor stays current with the latest industry standards and continues to demonstrate competency with these practices.

The VSI also offers a Vinyl Siding Product Certification Program, which is designed for manufacturers to certify that their products meet industry standards. Vinyl siding that has been certified by this program has been shown to meet or exceed industry standards for the following performance measures:

  • Weatherability
  • Windload
  • Impact Resistance
  • Expansion and Shrinkage
  • Surface Distortion
  • Length, Width, Thickness
  • Color Retention (where applicable)
