Replace All the Interior Doors in a House — One Style, One Visit
Every door in the house is a different flat-panel from a different decade, half the knobs are brass and the closet doors are missing. One order, one crew, one style everywhere, done in a few days.
JMB Builders will replace all the interior doors in a house anywhere in the Twin Cities metro: every bedroom, bath, closet and hall door in one style and one hardware finish. We count and measure the openings from your photos, tell you what to order as slabs or prehung units, then hang them with even reveals, case the prehung ones, and set every strike. Priced per door at a whole-house rate, painting as its own line.

Replacing every interior door at once is the cheapest way per door to do it and the only way to get them all to match. Doors bought over the years never match: a six-panel here, a flat hollow-core there, a louvered closet door someone found on sale. When the whole house goes to one style, usually a two-panel shaker or a flat modern slab, with one hinge and lever finish on every door, the house reads as finished in a way that paint alone never does.
The decision on each opening is slab or prehung. If the jambs and casing are square, undamaged and you like the trim, slabs fitted into the existing jambs keep the trim and the paint on it; we mortise hinges to match your jambs, bore for the hardware and plane each slab to an even margin. If the jambs are chewed, out of square or you are changing the casing anyway, prehung units go in: old door and jamb out, new unit set plumb, cased, and the drywall touched up. Most houses are a mix. Hallway and bedroom doors as slabs, bathrooms and the closets with broken jambs as prehung.
The count matters more than anything else. Send us a photo of every door from the hall, with the tape across the slab width, and we send back a list: opening, size, handing, slab or prehung, passage or privacy hardware. You order from that list at whatever store you like, or we supply the doors. Then the crew comes for a few days and does not leave until every door latches with a push and every reveal is the same on both sides.
What you supply
- The doors, from our list: slabs or prehung units by size and handing, in one style, or have us supply them
- Hardware for every door in one finish: passage levers for halls and closets, privacy for bedrooms and baths, dummies for closet pairs
- Hinges in the same finish, three per door, when the slabs or prehung units do not come with them
- A photo of each door from the hallway with a tape across the slab width, and a wide shot of the hall
- Paint or stain color if you want us to finish the doors; painting is a separate line, or paint them yourself
What JMB supplies
- The order list: every opening measured from your photos with size, handing, slab vs. prehung, and hardware type
- Removal and haul-away of the old doors, and the old jambs and casing where prehung units go in
- Slabs fitted to existing jambs: hinges mortised to match, hardware bored, edges planed to an even margin
- Prehung units set plumb and square, shimmed at hinges and strike, cased in your profile or a standard one
- Every hinge and lever installed, every strike set so the door latches with a push
- Door stops on every door, and the drywall patched where an old jamb was wider
- Filled, caulked and primed casing; painting or staining of doors and casing quoted as its own line
- Photos of the finished doors in your job folder
How it is priced: per door
Quoted in writing from your photos within one business day. What moves the number:
- Slabs into existing jambs vs. prehung units with the jamb and casing replaced; most houses are a mix
- Number of doors; a whole-house job is priced per door at a house rate that drops as the count goes up
- Hollow-core vs. solid-core doors, which take longer to fit and need heavier hinges
- Closet doors in the count: bifold and bypass sets are priced per opening alongside the swing doors
- Odd sizes and old jambs that need planing, shimming or a strip added to fit a standard slab
- Matching an existing casing profile vs. a standard one on the prehung openings
- Painting or staining every door and casing, quoted as a separate line
A photo of every door from the hall with a tape across it, plus one photo of a door edge at the hinge, gets you the full order list and a firm per-door quote.
How long it takes
A typical house of ten to fifteen doors: two to three days for a mix of slabs and prehung units. Painting adds time on a separate schedule.

Situations and options
Slabs into the existing jambs
Keeps the trim and the paint on it. Each slab is fitted to its jamb: hinges mortised to match, planed to an even margin, bored for your hardware. Best when the jambs are square and the casing stays.
Prehung units throughout
Old doors, jambs and casing out; new units set plumb and cased in one profile. The choice when the jambs are damaged, the casing is changing anyway, or the house has never had square doors.
Hollow-core to solid-core
Same job with heavier doors. Solid-core slabs quiet the bedrooms and feel like a different house when they close. They need ball-bearing hinges and a little more fitting time per door.
Closet doors in the same package
Bifolds and bypass sets replaced at the same time in the matching style, on new track and pivots, so the closet doors stop being the odd ones out.
Replace All the Interior Doors in a House — One Style, One Visit: questions, answered
Should I buy slabs or prehung doors to replace every door in the house?
Slabs if the jambs are square, undamaged and you want to keep the casing and the paint on it. Prehung if the jambs are chewed, the doors have never hung straight, or you are replacing the casing anyway. Most houses end up a mix, and we tell you which for each opening from your photos before you order. Slabs cost less per door to buy but take more fitting; prehung units cost more to buy and go in faster.
How long does it take to replace all the interior doors in a house?
A house with ten to fifteen doors takes two to three days once the doors are on site. Slabs into existing jambs run a little slower per door than prehung swaps because each one is fitted. Add a day when the casing is changing on every opening. Painting happens after, on its own schedule, or you paint the doors yourself.
Do all the doors have to be the same size?
No. Bedroom doors, bathroom doors and closet doors are often three different widths in the same house, and a few will be odd. Every opening gets measured from your photo with a tape across the slab, and the order list gives each one its own size and handing. Standard sizes are stocked; odd ones are special-order or a stock slab cut down.
Can you keep my existing casing?
Yes, with slabs. The casing and jambs stay and the new slab is fitted to them, so nothing on the wall changes. With prehung units the casing comes off with the jamb and goes back new, in the same profile if we can match it or a standard one if you want a change. You can also keep the casing on most doors and only replace it on the few openings that need a prehung unit.
Do the new doors come painted?
Slabs and prehung doors from the store come primed, not painted. We hang them primed with the casing filled and caulked. Painting every door and the casing is offered as its own line on the quote: doors come off the hinges and are sprayed flat, then rehung. Or leave them primed and paint them yourself before or after we hang them.
What about closet doors and the door to the garage?
Closet bifolds and bypass doors go in the same order and the same visit, in the matching style, on new track and hardware. The door from the house into an attached garage is different: it has to be a rated, self-closing exterior door, not an interior slab, and it is quoted as its own line if you want it replaced at the same time.
