Scuffed doors and yellowed trim make a whole room look tired, even with fresh walls. Lumen Painting offers door and window frame painting across Toronto and the GTA as its own service or as part of an interior job: doors, door frames, casings, baseboards, crown moulding and the inside of window frames.
Trim takes patience: filling, sanding between coats, caulking every gap and laying the enamel on smoothly. The estimate is free, and the work is covered by a written workmanship warranty.
What is included

How we do it
- Remove hardware
Handles, hinges plates and strike plates are removed or carefully masked.
- Fill and caulk
Dents and nail holes are filled; gaps between trim and walls are caulked for a clean line.
- Sand and clean
Glossy old paint is scuff-sanded and degreased so the new enamel bonds.
- Prime where needed
Bare wood, repairs and stains are primed; a bonding primer goes on hard, glossy surfaces.
- Enamel coats
Two smooth coats of trim enamel, with light sanding between coats for a better finish.
Stained wood trim to painted white
Many Toronto homes from the 1980s and 1990s have orange-toned oak or pine trim and doors. Painting them white or a soft colour brightens a house more than almost anything else. Stained wood needs cleaning, sanding and a stain-blocking primer so the wood tones and knots do not bleed through the new paint.
The right sheen for doors and trim
Semi-gloss is the classic choice for trim and doors: it stands up to hands, vacuum bumps and cleaning. Satin gives a softer look that some homeowners prefer in living rooms. We recommend a sheen in your quote and keep it consistent through the house.
Exterior frames are a separate job
The outside of your windows and your front door face the weather and need exterior products. See exterior window frame painting for frames, sills and shutters, or exterior painting for the rest of the house.
What affects the price
- Number of doors
- Doors are usually priced per door, with both sides and the edges included.
- Door style
- Six-panel and French doors take longer than flat slab doors.
- Length of trim
- Baseboards and casings are measured through the house; tall Victorian trim takes longer.
- Colour change
- Going from stained wood or dark trim to white usually needs primer and an extra coat.
- Condition
- Peeling, cracked or water-damaged trim needs more prep and repair.
Every quote is free, written and based on a visit, so you know the full price before any work starts.
Door & Window Frame Painting questions
Do you paint both sides of interior doors?
Yes. Doors are usually painted on both sides and on the edges, and the price is quoted per door.
Can you paint stained wood trim white?
Yes. We clean and sand the trim and use a stain-blocking primer so knots and wood tones do not bleed through, then finish with enamel.
Do you take the doors off to paint them?
Sometimes. Depending on the door and the finish you want, we paint them in place or take them off and lay them flat.
What sheen do you recommend for trim?
Semi-gloss is durable and easy to clean; satin is a softer look. We recommend one in your quote and keep it consistent.
Can I book just doors and trim?
Yes. Doors, frames and trim can be booked on their own or added to an interior painting job.
