How Much Does It Cost to Replace Interior Doors and Trim?

This is the easiest question in our business to answer honestly, because door and trim work prices off two things you can count yourself. How many doors, and how many linear feet of trim.

Our interior doors and trim packages generally run $2,000 to $12,000. A few doors and one room of base sits at the bottom. A whole-home package with solid-core doors, new casing on every opening, and taller baseboard throughout sits at the top.

How to estimate your own project

Walk the house and count. Interior doors, including closets and pantry. Then count openings that get cased, which includes doors, windows, and any cased passageway. Then measure the perimeter of each room for baseboard.

Most single-story tract homes here have 10 to 14 interior doors. Two-story homes usually run 14 to 20. Baseboard commonly lands between 300 and 600 linear feet.

Those three numbers get you close before anyone walks through your door.

Where the cost sits

The doors. A hollow-core replacement is inexpensive. A solid-core door costs several times more in material alone, and it is the upgrade most people feel immediately, because the door has weight and the room gets quieter. Prehung units cost more than slabs but install faster and hang truer in a wall that has moved.

The casing. Casing is where a house stops looking builder grade. Standard tract casing is a thin two and a quarter inch colonial profile. Moving to a three and a half or four and a half inch profile with a proper reveal changes every opening in the house. Material cost is modest. Labor is real, because every opening gets fit.

The baseboard. Taller base costs more per foot and more per corner, since scarf joints, inside corners, and outside corners all take time. Rooms with many corners cost more per square foot than rooms with few.

Removal and disposal. Old doors, old trim, and the nail holes and drywall damage they leave behind. This is a real line item and any bid that omits it is going to grow.

Finish. Painted or stained, we carry finish through rather than leaving you a set of primed trim and someone else's phone number.

A real project reference

The Ballast Rd. great room and kitchen in Menifee was $34,952 over 14 days. That is not a door and trim package. It is a full downstairs transformation of a builder-grade tract home with a framed fireplace pop-out, vertical nickel-gap paneling throughout, a hand-built rift-sawn white oak mantel, a built-in with floating shelves, and a heavily paneled kitchen island.

But window and door casing across the whole downstairs was one of the named cost drivers on that job, and it is worth understanding why. Once you upgrade paneling and millwork in a room, the old thin casing around every window and passageway becomes the loudest thing in it. Casing the whole floor was not decoration. It was what made the rest of the work read as one house instead of one wall.

That is the lesson we would pass on. Trim is a system. Upgrading it in one room and not the next usually looks worse than leaving it alone.

What you get at each level

Around $2,000 to $4,000: a partial scope. New base in the main living areas, or a handful of doors replaced, or casing on one floor's openings.

Around $4,000 to $8,000: a substantial package. Most or all doors replaced with solid-core slabs or prehungs, upgraded casing on every opening in the main areas, and new base throughout the same footprint.

Around $8,000 to $12,000: whole-home. Every door, every opening cased, taller base in every room, crown where the ceilings suit it, hardware installed, and everything finished.

Ways to reduce the number

Reuse the jambs and hang slabs where the existing frames are square. Keep the existing base and upgrade only casing, or the reverse. Do the public floor first and the bedrooms later. Choose paint-grade material, since a well-installed paint-grade profile looks better than a poorly installed stain-grade one.

We will lay those options out rather than quietly pricing the maximum version.

Jamb condition, wall thickness, floor level, and how much the house has settled all change what a door install takes. A 1994 house and a 2019 house are different jobs.
