- Based in Zimmerman, Sherburne County
- Baseboard per foot, casing per opening
- Coped corners, base scribed to the floor
Zimmerman grew fast through the 1990s and 2000s, and most houses from that run got the same trim package: narrow base, thin flat casing, corners mitered with no glue, all shot up in a day. Twenty-some winters later the miters have opened, the base has pulled off the wall where the floor settled, and caulk is holding the outside corners together.
Replacing it is mostly carpentry, not material. We pull the old base and casing, check walls and floors with a straightedge, and set a taller base scribed to the floor so the top line runs straight even where the subfloor dips. Inside corners get coped, outside corners mitered and glued. Casing goes on with the same reveal at every door and window.
Being based in Zimmerman, a one-room job after new flooring or a dining room of crown is easy to fit into the schedule. We also trim out basement finishes, and windows another company set and left with bare drywall or foam showing at the jamb.

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 window and door openings
- Profile height: a taller base or a built-up casing takes more material and time
- Crown added in a dining room, living room or primary bedroom
- Paint-grade MDF or pine vs. stain-grade wood to match existing trim
- Floors that dip and need the base scribed or a shoe added
- Old trim to remove and haul away

Situations and options
Builder trim swap
Pull the narrow base and flat casing from a 1990s or 2000s house and put in a taller base and a casing with a profile, room by room or the whole main floor.
Crown in the main rooms
Crown in a dining room, living room or primary bedroom, coped at the inside corners and held to a straight line where the ceiling waves.
Basement finish trim
Base, casing and window returns in a finished lower level, often in the same project as an egress window for a new basement bedroom.
Trim-out after window replacement
Casing, jamb extensions, stool and apron on windows that went in with no interior trim, or with trim that does not match the rest of the house.
Trim Carpenter in Zimmerman, MN: questions, answered
Can you replace the trim in my 2000s house without new floors?
Yes. We pull the old base and casing, patch the wall where it sat, and set the new trim to the existing floor. A taller base covers the old paint line, which can save repainting the walls. If new flooring is coming soon, do the floors first and we set the base after.
How do you install crown when the ceiling is not flat?
Ceilings in 1990s and 2000s houses often wave a little where the trusses moved. We set crown to a straight line and fill a small gap at the ceiling with caulk, or float the ceiling where the dip is bigger. Inside corners are coped so they stay tight as the house moves through the seasons.
Do I need a permit for new trim in Zimmerman?
Swapping baseboard, casing and crown in existing rooms is finish work and is usually not a permit item, but rules vary. Most cities require a permit for a basement finish or a new egress window. We check with the City of Zimmerman building department and pull the permit when the job needs one.
Will new trim look odd next to the trim I keep in other rooms?
It can, so we plan it. If you only do part of the house, we either match the existing profile from stock or put the new style in rooms that stand on their own, like a basement or the upstairs. Two profiles in rooms you see from one spot look like a mistake, and we flag that on the quote.
Can you trim out windows another company installed?
Yes. We add jamb extensions to bring the jamb flush with the drywall, then case it and add a stool and apron if you want them. It does not matter who set the windows. Send a photo of each window from inside and we reply within one business day.
Do you do trim work outside Zimmerman?
Yes. Zimmerman is our base, and we do trim work across Sherburne County and the north metro, including Princeton and Otsego, and across the Twin Cities. Send photos for a reply within one business day, or book a free in-home estimate.
