Trim is counted, not measured
Walls are priced by area; trim is priced by the piece or by the foot. A painter walking through your home will count interior doors and whether both sides are painted, door casings, window casings and stools, baseboards, crown molding, chair rail and any built-in shelving. Raised-panel doors take longer than flat slab doors, because each panel and its edges are brushed in order. Ask for the counts on the proposal.
Weirton in Census figures
Census QuickFacts puts Weirton city at 8,707 households, with 2.11 persons per household (2020–2024 figures). Weirton city covers 18.06 square miles of land area (2020), and its 2020 census population density was 1,061.4 persons per square mile. Those are the bureau's figures as published, and they say nothing about the trim in any particular house.
The oil-to-latex question
Much trim painted in past decades was finished in oil-based enamel, and latex applied straight over glossy oil can peel off in strips. A painter will usually test the old finish (a rubbing-alcohol test is common), then scuff-sand and apply a bonding primer before any water-based topcoat. That primer coat on every piece of trim is a real cost and a frequent difference between bids. Ask whether your trim will be tested and what primer is planned.
Filling, caulking and sanding
Good trim work is mostly prep:
- nail holes filled and sanded flush;
- gaps between trim and wall caulked;
- dents and chips in doors filled;
- old drips and brush marks sanded down;
- a light sanding between coats for a smooth finish.
Trim that skips those steps can look fine from across the room and rough up close. Our drywall repair and surface preparation guide covers filling and caulking.
Doors on or off
Some painters paint doors in place, with the hinges masked or removed. Others take doors down, lay them flat and spray or roll them, which gives a smoother finish but takes longer to set up and needs space to dry. Ask how doors will be done and how long they'll be off their hinges.
Enamel and sheen
Trim and doors are usually satin or semi-gloss, for washability and contrast with the walls. Waterborne alkyd and urethane-modified enamels level better than ordinary wall paint and dry harder, but take longer to cure fully. See paint sheens and finishes.
Old paint on trim
Sanding trim for adhesion disturbs old layers, and friction surfaces such as doors and window sashes wear old paint into dust. 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. If your home was built before 1978, ask the painter whether the firm holds RRP certification and how they'll contain dust while sanding trim.
Color and contrast
White trim against colored walls is the most common choice, and a trim color change, such as a dark stained look to white or white to a deep color, often takes an extra coat. Trim painted the same color as the walls is quicker but usually gets a different sheen to look finished.
Comparing trim bids
- Doors, casings, baseboards and other trim counted?
- Doors painted on both sides?
- Old finish tested, and bonding primer included?
- Filling, caulking and sanding listed?
- Enamel named?
- Doors removed or painted in place?
