Comparing full-frame and insert (retrofit) door replacement methods on cost, scope, and when each makes sense.
When a contractor quotes a door replacement, there are actually two different jobs they might be describing: an insert (retrofit) replacement that reuses your existing frame, or a full-frame replacement that tears the opening down to the studs. They solve different problems, and the price difference reflects that.
Insert replacement sets a new, slightly smaller frame and door inside your existing frame, leaving the surrounding structure untouched. It's faster — usually a half-day job — and cheaper, typically $600–$2,200 installed. It only works when the existing frame is square, dry, and free of rot; it can't fix structural problems underneath.
Full-frame replacement removes the entire frame — sill, jambs, and header — down to the wall studs and rebuilds the opening from scratch. It takes longer (a full day, sometimes two) and costs more, typically $1,500–$4,500+, but it's the only method that actually fixes rot, water damage, or an opening that's shifted out of square.
Insert replacement is faster and cheaper, and it's the right call when the existing frame is square, dry, and free of rot — most straightforward door swaps qualify. Full-frame replacement costs more and takes longer, but it's the only option that actually fixes a rotted sill, water-damaged jambs, or an opening that's shifted out of square. Any contractor should physically inspect your frame before quoting a price — treat a phone-quoted insert price as provisional pending that inspection.
