Interior Doors, Baseboards, and Casing
Interior trim defines the edges of doors, windows, floors, and openings. Services include interior door installation, door and window casing, baseboards, shoe molding, back bands, plinth blocks, and related profiles.
New trim is selected according to ceiling height, door style, existing millwork, and the scope of the room or renovation. When trim remains elsewhere in the house, we measure its profile and dimensions before recommending how the new work should connect with it.
Coordinating Baseboards and Casing
Baseboard height and casing width should be considered together. The profiles need an intentional transition where they meet at door openings. Back bands, plinth blocks, or changes in profile thickness may be used where appropriate to the design.

What We Install
- Baseboard Installation — Single-piece or built-up baseboard with optional base cap and shoe molding, sized to the ceiling height and existing trim.
- Door Casing and Trim — New casing on existing openings or full door-and-casing replacements, with consistent reveals and fitted joints.
- Window Casing — Picture-frame casing or traditional casing with stool and apron, matched across the room.
- Interior Door Installation — Shaker, raised-panel, and flat-slab doors; prehung and slab installations; hinges, knobs, and latches set correctly.
- Closet Doors — Bifold, bypass, and swing closet doors, including custom shaker bifolds with new casing.
- Chair Rail & Accent Trim — Chair rail, panel molding, and transition trim that ties into your baseboard and casing profiles.
Inside Corners
Inside corners are fitted to the actual wall conditions. Coping or mitering may be used according to the molding profile, material, and connection between pieces.
Replacing Existing Baseboards and Casing
Replacing existing baseboards or casing may expose wall surfaces, flooring edges, previous paint lines, or differences in material thickness. These conditions are reviewed before the new profile is selected and the preparation responsibilities are documented.
What Drives the Cost of Trim & Door Work?
- Linear footage — Baseboard and casing are measured by the foot; the number of rooms drives the total.
- Profile choice — Single-piece baseboard installs faster than built-up base with cap and shoe.
- Door count and type — Prehung replacements, slab swaps into existing jambs, and closet door systems each take different amounts of work.
- Removal and disposal — Pulling old trim cleanly, without tearing up walls, takes time done right.
- Condition of walls and floors — Out-of-level floors and wavy walls mean scribing and fitting rather than straight runs.
During the free estimate, we measure the rooms and openings, review profile options, and provide a written price for the agreed scope.
Our Process
- Walkthrough & measurement — We measure every room and opening and talk through what stays, what goes, and what it should become.
- Profile & door selection — We pick baseboard, casing, and door styles that fit the age and style of your home — with samples, not catalog guesses.
- Clear written scope — You know exactly which rooms, which profiles, and which doors are included before work begins.
- Installation — Inside corners coped, outside corners cut to the true wall angle, doors hung plumb with even reveals.
- Caulk, fill & walkthrough — Nail holes filled, joints caulked, everything paint-ready, and a final walkthrough together.
