Interior trim frames transitions between walls, doors, windows, floors, and decorative elements. Small differences in reveal, joint angle, profile, and wall condition are easy to see once the trim is painted.
Common Interior Trim Problems
Issues may include loose casing, damaged corners, open joints, split trim, missing returns, trim that no longer meets after another renovation, or a short damaged section around a door or window.
The condition behind the trim matters. Wall damage, a loose jamb, or moisture should not be hidden with new molding.
Repair or Replace?
A localized repair may work when the profile can be matched and adjacent material is still usable.
Replacement may be better when several joints have failed, the old profile cannot be matched, the opening has changed, or the homeowner wants a different trim style.
New Installation and Replacement
The project should account for door or window reveals, drywall thickness, jamb position, baseboard transitions, flooring, and adjacent trim.
Profiles should be selected with the surrounding room in mind rather than installed as an isolated strip.
Installation Process
Existing trim is removed where necessary, the opening is measured, and new pieces are cut to fit the actual corners and transitions.
Fastening, joints, nail holes, caulk, and finish preparation depend on the material and final appearance.
Final Check
Trim should meet consistently at corners and transitions and should not interfere with doors, windows, drawers, or nearby hardware.
FAQ
Can only one damaged casing piece be replaced?
Often, if the profile and finish can be matched sufficiently.
Does trim work include drywall repair?
Only minor incidental preparation should be assumed. Dedicated wall damage belongs to drywall repair.
Can old trim be reused?
Sometimes, if it can be removed without damage and still fits the revised opening.
Is painting included?
Finish work should be confirmed separately.
