Ten Tips for Good Installation

  1. Read and follow the installation instructions.
  2. Install your Andersen products only in the vertical position.
  3. Check the rough opening to make sure it is sized properly and is square and level.
  4. Apply proper flashing under and around window and door openings.
  5. Double-check the alignment of the window before finally anchoring it in the wall, and properly secure using appropriate fasteners.
  6. Insulate the interior cavity between the window frame and the rough opening. Do not overpack.
  7. Stain and/or seal all unfinished wood surfaces promptly to minimize moisture absorption.
  8. Keep paint off the weatherstrip and the interior hardware finish.
  9. Protect the window during construction and plastering.
  10. Ensure proper installation and operation of the window before applying the interior trim.

Proper measurement and installation of Andersen® products is the sole responsibility of the architect, building owner, contractor and/or consumer.
