The slowest paint in the house
Trim is where a paint job is judged up close. Baseboards, casings, crown molding, window stools and doors are touched, kicked and wiped every day, and they're painted with harder, glossier enamels that show every brush mark and every bit of poor prep. A painter can roll a wall in minutes; cutting a run of casing cleanly takes far longer. That's why a trim-and-doors job can cost more than people expect for so little surface. Here's what drives the price; the figures themselves only come after a painter has looked.
A house full of hands
Blacksburg, VA has 13,840 households in Census QuickFacts for 2020-2024, with 2.54 persons per household. In any of those homes, every person in the house opens doors, brushes past casings and kicks baseboards. That daily handling is the reason trim gets a harder finish than walls, and the reason worn trim usually needs more prep than the walls around it.
Measuring the job
- Baseboards and casings are priced by the length, and by how many profiles they have. A plain flat board is quick; a stepped or carved profile is not.
- Crown molding is slower, because it's overhead and has two edges against the wall and ceiling.
- Doors are counted one by one: slab doors are quicker than paneled ones, and both faces and all edges are usually included.
- Door frames and jambs come with the doors, and need care around hinges and strike plates.
- Window stools, aprons and casings add up quickly in a room with several windows.
The finish that's there now
The biggest prep question is what's already on the trim. Older trim may be coated in oil-based enamel, and latex paint won't grip glossy oil without a sanded surface and a bonding primer. A painter may test with a little rubbing alcohol: latex softens, oil doesn't. A change from oil to latex adds sanding and priming time to every foot of trim.
Stained and varnished trim being painted for the first time also needs scuffing and a stain-blocking bonding primer, or the wood's tannins can bleed through light colors.
Caulk and filler
Gaps where trim meets the wall, open miters at corners and nail holes all need filling. Flexible caulk goes in the gaps; wood filler or spackle goes in the holes, sanded flush. On trim that has never been caulked, this alone can take a long time.
Doors on or off
Doors can be painted in place or taken off, laid flat or hung, and painted in a work area. Off-the-hinge work gives a smoother finish and gets the edges right, but adds removal, labeling and rehanging. Hardware is usually removed and replaced. Ask which approach the bid assumes.
Enamel, sheen and drying
Trim enamels are harder and slower to dry than wall paint, and they need proper drying time between coats or they stay soft and stick. Semi-gloss and satin are typical; higher gloss shows more flaws and needs better prep. Our paint sheens and finishes guide explains the choice, and drying time between coats is part of what you're paying for.
Lead-safe sanding
Under EPA's Renovation, Repair and Painting Rule, anyone paid to do work that disturbs paint in homes, childcare facilities and preschools built before 1978 must hold RRP certification, firms included, even sole proprietorships, and their workers must be trained in lead-safe work practices.
Trim prep is mostly sanding, and on a pre-1978 home that sanding disturbs paint. Wet sanding, containment, HEPA cleanup and the extra time they take are part of the price there. You might ask whether the firm holds RRP certification.
A trim proposal should list
- the rooms, with baseboards, casings, crown and window trim marked;
- the number and type of doors, and whether both faces are done;
- primer for oil-to-latex changes or stained wood;
- caulking and filling;
- the enamel, sheen and number of coats.
