A trim carpenter in St. Paul, MN works across a wide span of houses. JMB Builders fits casing with back band and baseboard with cap in Victorian and 1920s homes, patches trim where past remodels cut into it, and runs simpler painted trim quickly in postwar houses. Baseboard is priced per linear foot, casing per opening. Send photos and we reply within one business day, or book a free in-home estimate.
- Base per linear foot, casing per opening
- Back band casing and capped base
- Trim patched where remodels cut in
St. Paul's housing runs from Victorian-era homes near the river bluffs through 1920s bungalows to the postwar sections. The older trim is layered: casing with a back band around the outside edge, baseboard with a separate cap and shoe, sometimes a head cap over the doors. That layering is why a patch can match. We rebuild each layer from stock pieces so the new run meets the old one with the same reveals.
Most of the trim calls we get in older St. Paul homes come after someone else's remodel. A wall was moved and the base ends in a butt joint. A window was replaced and cased in plain stock. A doorway was cut through and never trimmed. We remove the odd pieces, carry the original profile through, and put the joints where they disappear: at a corner, a plinth or a door.
Postwar St. Paul houses are simpler work. Narrow painted casing and short base come off, and taller coped base and wider casing go on, often a whole floor in a couple of days. Homeowners in Shoreview and White Bear Lake hire us for the same scope. Painting is quoted as a separate line — or leave it primed and caulked and paint it yourself.

What JMB supplies

- Stain-grade oak, fir or pine, or primed paint-grade stock
- Removal of mismatched trim from past remodels, with the plaster edge protected
- Joints placed at corners, plinths or doors so patches do not show
- Coped inside corners and base scribed to the floor
- Filler, glue at the miters and paintable caulk on painted work
- Photos of the finished rooms in your job folder
- Painting or staining when you want it done, quoted as its own line
How it is priced: per linear foot
Quoted in writing from your photos, with a reply within one business day. What moves the number:
- Linear feet of base and the number of openings
- Layered profiles with back band, cap and shoe vs. one-piece trim
- Stain-grade wood to match vs. paint-grade
- Removing and patching around trim from past remodels
- Plaster walls and floors that need scribing
- Whole-floor painted trim in postwar homes, which runs faster per foot
Send a close-up of the casing corner and the base with a tape across each so we can read the layers and widths.
How long it takes
Patching trim at a few openings: a day. A postwar main floor of new base and casing: two days or so. Matched stain-grade trim through older rooms: three to five days.

Trim Carpenter in St. Paul, MN: questions, answered
What is back band casing, and can you match it in my St. Paul house?
Back band is a small molding applied around the outside edge of flat casing, which gives the trim a thick, finished edge. Many older St. Paul houses have it. We build the casing and the back band separately from stock to the widths of the original, so the new opening matches the rest of the room.
A past remodel cut into my trim. Can you patch it in?
Yes. We take off the mismatched pieces, rebuild the original profile layer by layer, and put the joints at a corner, a plinth or a door where they disappear. On stained trim we test the stain on offcuts first so you can pick the closest match.
Is trim work in a postwar St. Paul house different?
It is simpler and faster. The trim is usually narrow and painted, so it comes off quickly and taller base and wider casing go on, often a whole floor in a couple of days. Most of those homeowners want a cleaner, heavier look, not a match to the old trim.
Do I need a permit for trim carpentry in St. Paul?
Replacing trim on its own is generally not permit work. Moving a wall, changing an opening or adding wiring can be. When the job includes any of that, we check with the City of St. Paul building department and pull the permit when one is needed.
Can you work room by room while we live in the house?
Yes. We finish one or two rooms at a time, keep cutting in one spot with dust control, and clean up at the end of each day so the house stays livable. Tell us which rooms have to be usable first and we plan around them.
How is trim carpentry priced in St. Paul?
St. Paul trim is quoted by the foot for base and by the opening for casing. Layered profiles with back band and cap, stain-grade wood and patching around past remodels cost more than painted one-piece trim. Finish work is listed separately, and the quote is built from your photos or a visit to the house.
