I intend to buy and install Andersen Sliding Patio doors. My understanding the doors are unstained unfinished pine interior that is usually stained. Does it mean you have to mask the windows glass and stain the door itself? Does the door have any interior trim?
I installed a dozen or so Andersen windows in my house. The window itself is not stained as it is not exposed. I stain the trim that is then attached to the window.
