Interior frames can be wood without sills.<\/li>\n<\/ul>\n<\/li>\n\n\n\n<li><strong>What\u2019s Your Budget?<\/strong>\n<ul class=\"wp-block-list\">\n<li>Steel can be economical; wood\/composite sits in the mid\u2011range; fiberglass is often premium but low\u2011maintenance. Consider lifetime costs, not just purchase price.<\/li>\n<\/ul>\n<\/li>\n\n\n\n<li><strong>DIY or Hiring a Pro?<\/strong>\n<ul class=\"wp-block-list\">\n<li>DIY: pre-hung is easiest.<\/li>\n\n\n\n<li>Custom sizes\/out\u2011of\u2011square walls: consider a pro (they\u2019ll shim, plane, and tune for perfect reveals and latch alignment).<\/li>\n<\/ul>\n<\/li>\n\n\n\n<li><strong>What Are You Replacing?<\/strong>\n<ul class=\"wp-block-list\">\n<li>Solid, square frame: a new slab may suffice.<\/li>\n\n\n\n<li>Rot, rust, or damage: replace with a full pre-hung unit.
