Baseboards, Trim & Flooring Transitions Explained

Baseboards: Reset vs. Replace

Baseboards are the visual frame of every floor. The default choice is to pull existing baseboards, install the new LVP with proper expansion gap, then reset the same baseboards afterward. Pull-and-reset gives the cleanest finish — no double trim, no awkward gap, no compromise.

Replacement is the right call when:

• Existing baseboards are short (2"–3") and you want a more substantial look.
• Trim is damaged, water-stained, or brittle from age.
• You want a modern profile (square-edge MDF vs. colonial).
• You're already repainting and want clean new trim with the new floor.

Quarter Round and Shoe Molding

Floating LVP needs a small expansion gap at every fixed object. Quarter round or shoe molding covers that gap at the baseboard.

Painted shoe trim is the standard; stained-to-match shoe is an option if you prefer trim that disappears into the floor rather than the wall.

Transitions Between Floors

T-Bar (T-Molding)

Used where two flooring surfaces of equal height meet — for example, LVP in the bedroom meeting LVP in the hallway through a doorway. The T-bar floats over the expansion gap and creates a clean break.

Reducer

Used where LVP meets a thinner floor (vinyl, hardwood that sits lower, exterior threshold). A reducer ramps from the higher floor down to the lower one.

End Cap / Threshold

Used at exterior doorways, sliding-door tracks, and where flooring ends without a matching surface beyond. Closes the edge cleanly.

Carpet Transition

Used where LVP meets carpet — typically at bedroom doorways. A purpose-made transition holds the carpet edge and creates a tight, durable seam.

Stair Nosing

Bullnose pieces finish the front edge of every stair. Color- matched to the plank pattern for a unified look between landing and stair.

Doors and Thresholds

Interior doors need clearance over the new LVP. Most doors need a small undercut — a few millimeters off the bottom — to swing freely. We mark and trim on-site for hollow-core doors; solid-core or specialty doors may need to be removed for shop trimming.

Exterior doorways are finished with thresholds sized to your floor height and door. Sliding glass doors usually don't need adjustment, but if they do, that's coordinated as part of the install.

Stairs and Nosings

Stairs are the most time-consuming part of any finish day. Each tread and riser is measured, cut, and installed individually. The bullnose nosing matches the plank pattern for a continuous look from landing to stair.

Plan on roughly a half day to a full day for a typical flight of stairs, depending on width and shape. Curved or winding stairs take meaningfully longer.

Paint Touch-Up

Pulling and resetting baseboards exposes paint scuffs along the top edge. New baseboards always need painting. We can:

• Leave touch-up entirely to the homeowner (most common).
• Coordinate with a painter you already know.
• Recommend a painter for the project.

If you're repainting walls as part of a larger refresh, do baseboards and walls together for the cleanest result.
