Installation Creates Opportunity

Choosing the right contractor is one of the most important aspects of any window and patio door purchase. Proper installation is critical for peak performance of Andersen® products. To ensure our customers absolute peace-of-mind for each installation, we enrolled in the Andersen Certified Installer program. Our customers can have confidence that their windows and patio doors will be installed correctly.

Key Requirements for Andersen Installer Certification


One of our employees attended on-sight training at Andersen Windows in Bayport, MN. The 3-day course covers all aspects of installation and is designed for advanced installers.


Your company agrees to supervise all projects involving the installation of Andersen® products and abide by all applicable building codes and regulations. By attending the training, you also agree to follow current Andersen product installation instructions, training guidelines and future recommendations.

Job Registration

We certify each project through a registration process to qualify that job for the 2-year installation limited warranty.

Agreements & Certificates

We supply Andersen with our installer registration, certificate of insurance, vehicle liability insurance and sign a Certified Installer Contractor Agreement.

It’s important for our staff to be

  • Experienced – we know Andersen products and how to install them
  • Trained – we’ve been through hands-on training for all products
  • Informed – we continually review new products and installation methods
  • Supported – we have the support of Andersen for ongoing needs
  • Trusted – just like Andersen, we stand behind our work

During our certification training, in 2016, we spent time at Andersen’s training facility working with various applications and methods of installation. We were able to see:

Hands-On Installation

We worked directly with window and patio door products including full engagement for successful installations.

Water Test

We viewed an actual water test and learned about Andersen’s innovative approach to water testing windows by testing our actual installation for leaks!

Reference Tools

All of our materials came home with us to use as reference for challenging installations or as every day reminders.

Tour of Andersen Research, Development, and Innovation Facility

We toured Andersen’s state-of-the-art equipment used to test products for durability, longevity, and compatibility. We also caught a glimpse of the extensive testing behind material development and installation procedure roadmaps.

We signed on as an Andersen Certified Installer because it gives us a unique look at the only product we install. Our replacement window and door teams are committed to continuing our local tradition of high quality. At Great Plains Windows and Doors we’re delivering a consistent experience to homeowners across the Minneapolis/St. Paul area. Andersen has helped us do that with its Certified Installer program.
