Labor only door installation is for doors homeowners have already bought, from Menards, Home Depot, Lowe's, a lumberyard or online. JMB Builders installs them anywhere in the Twin Cities metro: we remove the old door, repair the framing if needed, set the new unit plumb, flash and seal exterior doors, install the hardware and trim it out. Priced per door, quoted from your photos, with a reply within one business day.

A lot of homeowners would rather pick out their own door at Menards, Home Depot, or a local lumberyard and just hire someone to install it. That's a service most contractors won't touch — they want the markup on the door. JMB Builders does labor-only door installation throughout the Twin Cities metro, and we do it the same way we'd install a door we sold you: old door out, opening checked and repaired, new door set plumb and square, flashed, foamed, trimmed, and adjusted until it latches with a solid click.
A typical request looks like this: a homeowner replacing the front entry, the house-to-garage door, and the garage service door all at once, doors already sitting in the garage, and they just need someone to install them properly. That's a one-day job for us in most homes, and we quote it per opening before we start.

What you supply
- The door: prehung unit or slab, correct swing (handing) and rough-opening size
- Lockset, deadbolt and hinges if the door does not include them
- Exterior trim or brickmould if you want a specific style (we stock standard profiles)
- Your paint or stain color if you want us to finish the door — painting is quoted as a separate line, or paint it yourself
What JMB supplies
- Removal and haul-away of the old door and casing
- Shims, fasteners, low-expansion foam, sill pan and flashing tape for exterior doors
- Framing or rot repair at the opening when it is needed (quoted from the photos)
- Interior casing in a standard profile, or matched to what is on the other doors
- Weatherstripping, sweep and threshold adjustment so it seals on the first cold night
- Photos of the finished door in your job folder
- Painting or staining of the new door and casing when you want it done, quoted as its own line
How it is priced: per door
Quoted in writing from your photos, with a reply within one business day. What moves the number:
- Prehung unit (faster) vs. a slab that has to be fitted to an existing jamb
- Exterior door with sill pan, flashing and brickmould vs. an interior door
- Rot or framing repair at the opening, common at older exterior doors and garage service doors
- Whether the opening has to be resized for a different door size
- Matching an existing casing profile vs. a standard one
- How many doors in the same visit — the second door is always cheaper than the first
Send a photo of the door label or receipt with the opening photos and the quote covers everything, no allowances.
How long it takes
One exterior prehung door: about half a day. Interior doors: two to four in a day. Add a few hours when the opening needs framing repair.

Situations and options
Prehung exterior entry doors
Steel, fiberglass, or wood entry units from any retailer. We pull the old door, check the sill and framing, set the unit in a sill pan with flashing, shim and foam it, and trim the inside and outside.
House-to-garage fire-rated doors
The door between your house and attached garage needs to be a rated, self-closing unit in Minnesota. We install it with the correct closer, weatherstrip, and threshold so it seals against fumes and cold.
Interior prehung doors
Bedroom, bathroom, closet, and office doors — set in the opening, shimmed at the hinges and strike, cased, and fitted with your hardware.
Door slabs (not prehung)
A bare slab with no jamb or hardware. We fit it to your existing jamb, cut it to size if needed, mortise the hinges, bore for the lockset, and hang it so the margins are even all the way around.
Labor-Only Door Installation — We Install the Door You Bought: questions, answered
Do you install doors I bought myself?
Yes. That's exactly what this service is. Buy the door wherever you like — Menards, Home Depot, Lowe's, a lumberyard, or online — and we'll install it. We supply the shims, low-expansion foam, flashing tape, sill pan, caulk, fasteners, and casing or brickmould; you supply the door and any handle set or deadbolt you want on it. If you're unsure whether you ordered the right size or handing, send us the order details before you buy and we'll check it for free.
Can you install a door slab that isn't prehung?
Yes. A slab takes more fitting than a prehung unit — we trim it to the opening, mortise the hinges to match your jamb, bore for the knob and latch, and plane the edges so it swings without rubbing. It's a good option when your existing jamb and casing are in good shape and you don't want to disturb the trim.
How do I know what size door to buy?
Measure the width and height of the door slab you have now, and if you can, measure the rough opening (the framing behind the trim) and the jamb width (usually 4-9/16 inches for a 2x4 wall, 6-9/16 for a 2x6 wall). You'll also need the handing — stand outside the room or house facing the door; if the hinges are on your right, it's a right-hand door. If any of that sounds like a headache, take a couple of photos and send them over. We'll tell you what to order before you spend the money.
What happens if there's rot or damage behind the old door?
We find it on a fair number of exterior doors, especially at the sill and the bottom of the jambs. We'll show you what's there, tell you what it takes to fix it, and quote the repair before we go further. We won't set a new door on a rotted subfloor and call it done.
