Signs to watch
Is this you?
Scuffed, chipped, or yellowed trim
Old oil-based trim ambers over the years, and every baseboard collects vacuum marks and scuffs. Fresh white or crisp color on the trim can lift a whole room even if the walls stay the same.
Doors that stick, drip, or show brush marks
Doors take handling every day, and a soft or poorly leveled finish shows every touch. Panel doors especially need a finish that flows out smooth instead of gumming up in the corners and details.
Wall and trim colors that don't have a clean line between them
The line where trim meets wall is what your eye reads as 'well done' or 'rushed.' Fuzzy, wandering lines make even good paint look amateur. Crisp lines are a prep-and-patience thing, not a luck thing.
New trim, doors, or a remodel to finish out
Raw or primed-only casing, new doors, or a built-in from a remodel all need a proper enamel finish to look and wear right — and to protect the wood from the moisture and hands it's about to meet.
Your options
Enamels that cure hard and level smooth
Trim and doors take abuse walls never see — shoes, furniture, vacuums, hands, pets — so they get a different product than wall paint. We use Sherwin-Williams trim and door enamels: waterborne alkyd and hybrid finishes that flow out smooth like old oil paint but cure to a hard, washable, non-yellowing surface without oil's odor and slow dry. Prep is what makes it last and look sharp: degreasing off hand oils, sanding for adhesion, filling nail holes, caulking the gap where trim meets wall, and priming bare or previously oil-painted wood so the coat bonds instead of peeling. The crisp line comes from careful cutting and clean taping, not speed.
The method
How we do it
- 01
Assess the trim and choose the finish
We check what's on there now — old oil, latex, or bare wood all change how we prep — look at the sheen you want, and confirm color. Trim is usually a touch of contrast or a crisp white against the walls, and sheen matters: too flat scuffs, too glossy shows every flaw.
- 02
Clean, sand, fill, and prime
Degrease and sand for adhesion, fill nail holes and dents, caulk the trim-to-wall gaps, and prime bare wood or anything previously oil-painted. This is where a durable, smooth finish is actually made — skip it and the enamel chips at the first scuff.
- 03
Enamel coats and crisp lines
Smooth enamel applied and allowed to level and cure between coats, cut lines kept sharp against wall and ceiling, doors finished so panels and edges are even. Then we pull tape clean, reset hardware, and walk it with you.
Straight numbers
What trim and door painting actually costs
It's priced on linear footage, the number of doors, and how much prep the existing finish needs — not on paint. What moves the number: how many doors and how detailed they are (a flat slab is quick, a six-panel door is slow), total run of baseboard and casing, whether we're painting over old oil that needs extra bonding prep, how much filling and caulking the trim needs, and how sharp the color contrast is with the walls. Detailed trim done right is slow, careful work, and that's most of the number.
Where we do this work
Interior Trim & Door Painting: straight answers
Why use a special enamel on trim instead of the same paint as the walls?
Because trim and doors get touched, kicked, and cleaned constantly, and wall paint isn't built for that. Trim enamels cure much harder, level out smoother, and wipe clean without scuffing or marking. It's the difference between trim that still looks sharp in five years and trim that's chipped by next winter.
Can you paint over old oil-based trim with new water-based enamel?
Yes, but only with the right prep. Old oil paint has to be cleaned, sanded for tooth, and often primed with a bonding primer before a waterborne coat will stick — skip that and the new finish peels in sheets. We test what's on there and prep accordingly, which is exactly the step a rushed job cuts.
How do you get such straight lines where the trim meets the wall?
Clean surfaces, quality tape sealed down properly, caulk in the gaps so paint can't bleed under, and a steady hand cutting where tape won't go. There's no shortcut — the crisp line is just prep and patience, and it's the single thing that most makes a trim job read as professional.
Will the enamel yellow over time like old paint did?
The waterborne enamels we use are specifically formulated not to yellow the way old oil-based trim paint did, especially in low-light interior spots like closets and behind doors where oil ambers worst. That non-yellowing property is a big reason we moved to these finishes for whites and light colors.
