How to remove baseboards, casing and old doors yourself: step by step
Short answer
To remove baseboards, casing and old doors, follow the 10 steps below, from “Decide what is reused and what is trash” to “The wall is ready for the drywall phase”. Difficulty 1 of 5; for a first-timer, plan on about half a day. Stop before you scrape or sand if the building is from before 1978 — the paint on old baseboard and casing is the most common lead paint in an apartment.
Quick review by a licensed contractor on Oct 7, 2026. This is not a certification. Follow product labels where they differ.
Score, wedge, and walk the trim off slowly so the drywall paper stays on the wall. If the paint is pre-1978, do not sand or dry-scrape any of it.

Step by step
Step 1 of 10
Decide what is reused and what is trash
MDF baseboard almost never survives removal. Solid wood and anything original often does. That decision changes how carefully you work.
Step 2 of 10
Pre-1978 building: test the paint before you disturb it
Use an EPA-recognized kit (for example 3M LeadCheck). Cut a small V through every paint layer and swab the cut — on the baseboard, the casing, and the door edge. Positive means keep it wet, keep it whole, do not sand, and bag it sealed.
Step 3 of 10
Take the door slabs off at the hinges
With a helper holding the door, tap out the bottom pin first, then the middle, then the top — a nail set from below. Lift the door off. Stack slabs flat on the floor, not leaning.
Step 4 of 10
Score the caulk and paint line on both edges
A sharp utility knife along the top of the baseboard where it meets the wall, and again at the bottom. Two or three passes, cutting the film, not gouging the wall.
Step 5 of 10
Start at an outside corner or a cut end with a putty knife
Drive the stiff putty knife into the seam first to open a gap, then slide the pry bar in behind it. Always work over a stud.
Step 6 of 10
Walk the piece off in 12-18 inch steps
Pull a quarter inch at one nail, move along, pull a quarter inch at the next. Going for it all in one place snaps the trim and tears the wall. Label the back as each piece comes free.
Step 7 of 10
Casing comes off the same way, but from the jamb side
Score the jamb reveal line and the wall line, then pry near each nail. Head casing last on a mitered set.
Step 8 of 10
Pull every nail through the back of the piece
Grab the shank with end nippers and roll it out through the back face. The front stays clean.
Step 9 of 10
Pull or set every nail left in the wall and the jamb
A nail left proud catches the drywall knife later and tears the next wall. Sweep the floor for nails before anyone walks it.
Step 10 of 10
The wall is ready for the drywall phase
Damage found now is cheap to fix; found after painting it is not.
Quality check
- All baseboard, casing, and door slabs are out of the room
- No nails left standing in the walls or the jambs
- Torn drywall paper is marked for the patching task
- Reused pieces are numbered and stacked flat
- Pre-1978: paint was tested and nothing was sanded or dry-scraped
- Floor is swept for nails and debris is bagged
Common mistakes
- Prying without scoring the caulk and paint line first. Paint bridges the trim to the wall. Pry it and the paint takes a strip of drywall paper with it, which you then have to skim and sand. Score both edges first, every time. Mistake #1 in this task.
- Dry-scraping or sanding old paint. Pre-1978 paint releases lead dust when you abrade it. Keep the piece whole, mist it, and bag it. Never sand it in place.
- Hammering the nails back out through the face. It blows out the front of the trim you wanted to reuse. Pull every nail through the back with nippers.
- Levering the pry bar against the drywall. It punches a dent or a hole every time. Put a shim or a wide putty knife behind the bar and work at a stud.
- Not labeling trim you plan to reuse. Nothing in an apartment is square. A piece cut for one wall will not fit the next one. Number the back and note the wall.
- Leaning doors against a wall in the walkway. A door slab slides and falls. Stack them flat, or strap them to something.

When should I stop and call a pro?
Stop before you scrape or sand if the building is from before 1978 — the paint on old baseboard and casing is the most common lead paint in an apartment. Test with an EPA-recognized kit first. Lead-positive: work wet, keep pieces whole, no sanding, no heat gun, HEPA clean-up — or hire an EPA lead-safe certified firm (always, if a child under six or a pregnant person lives there). Never cut lead-positive trim with a power saw.
