Trim is where a paint job is judged. You can get away with a slightly uneven wall; you can’t get away with a gloppy baluster, a baseboard that bleeds onto the floor, or a door with brush marks you see every time you close it.
Staircases are the hardest of all: dozens of balusters, handrails that get gripped every day, treads and risers that need to stay usable while they cure. It’s slow, detailed work, and it’s the kind we like.

Not sure where your project fits? Call us and ask. We’ll tell you straight.
Our process
We look at the condition of the existing finish and talk through sheen. Trim usually looks best in semi-gloss or satin.
Floors, treads and walls around the trim are masked so lines stay clean.
Nail holes, dents and open joints are filled. Glossy old paint is scuffed so the new coat bonds.
Gaps between trim and wall are caulked. Bare wood and repairs are primed.
Brushed carefully along the grain, balusters one at a time, with time between coats to level out.
On staircases we work in sections so you can still get upstairs while paint cures.
Trim is mostly enamel, and enamel shows everything: brush strokes, drips at the bottom of balusters, ridges where a coat was overloaded. A smooth result comes from thin coats, light sanding between them, and patience.
Handrails and doors get touched every day. If the old glossy finish isn’t cleaned and scuffed first, the new paint peels at the grip points within months.

Yes. White balusters with a stained rail is a classic look. We mask the rail and treads carefully and keep the lines clean.
Yes. We plan the work so there’s always a usable path, for example painting alternate steps or one side at a time.
Usually satin or semi-gloss. They clean up well and look crisp against flat or eggshell walls. We’ll go over options with you.
It depends on the door and the finish you want. Doors we take down are painted flat for a smoother result and rehung when dry.
