  • While replacing a door into an existing opening requires few tools, it does require patience and care. Most interior doors can be unforgiving when not professionally installed.
  • We want you to get the perfect finish. At Fettig Millwork & Windows, we are experts at highlighting the natural beaty of the wood. Applying a finish will protect the wood from warping and provides a permanent seal.

  • After you pick the door style, wood and design you like, we will measure the opening. At Fettig Millwork & Windows, we take measurements from multiple points to get an accurate dimension.
