INSIST ON A CERTIFIED CONTRACTOR - Andersen® does.

Andersen is "the most recognized and preferred brand among homeowners,"* but they are only as good as the contractor who installs them.  As a homeowner, it's in your best interest to trust an Andersen Certified Contractor to install your new Andersen products.  Why? 
 
Because Andersen Certified Contractors do rigorous hands-on training to learn how to install Andersen windows and patio doors specifically.  And once they are certified, each contractor receives ongoing product information and support to stay up-to-speed on the latest best practices and advancements in technology in the industry.  Plus, you get a two-year installation warranty when you hire Encompass Builders, an Andersen Certified Contractor.
