Removing Popcorn Ceilings from Plaster in Older Toronto Homes: What's Different
Updated: Oct 19
Last updated: October 2026 | By the Renovated-Home team, East York, Toronto
Quick answer: Yes, popcorn texture can be removed from a plaster ceiling — but plaster is not drywall, and that changes the job. In older Toronto homes the texture was usually sprayed on years after the house was built, often to hide cracked or patched plaster. Taking it off exposes whatever it was covering. The removal itself is similar; what changes is the inspection before the work and the repairs after it.
Is your ceiling plaster or drywall?
Many Toronto homeowners aren't sure what's above them. A few simple checks:
The age of the house. Pre-war and early post-war homes — much of the Annex, Riverdale, Leaside and older parts of East York — commonly have plaster ceilings. Homes built from the 1960s onward are usually drywall.
The knock test. Plaster sounds solid and dense when you tap it. Drywall sounds lighter and more hollow between the joists.
A look from above or at an opening. If you can see into the attic or around a light fixture box, wood lath strips mean plaster. Paper-faced gypsum board means drywall.
Why popcorn texture ended up on plaster in the first place
Most popcorn ceilings were sprayed onto new drywall during construction. Plaster homes are older than that trend, so when you find popcorn texture on plaster, it was almost always added later — during a renovation, and often as a quick way to cover cracks or uneven patches instead of repairing them.
That matters for one reason: the ceiling under the texture may be in worse shape than it looks. Cracks that appear after removal are usually not new damage. They were there all along, hidden.
What changes compared to a drywall ceiling
Inspection before the work starts
Plaster is attached to wood lath by "keys" — bits of plaster that pushed through the gaps between the strips and hardened. Over decades, those keys can break, and sections of ceiling can come loose. Before quoting a plaster ceiling, we check for:
Hollow or dull-sounding areas when tapped, compared to a solid sound on sound plaster
Movement when a section is gently pressed
Sagging or bulging, especially near the centre of a room or along cracks
Stains from old leaks, which often show where plaster has weakened (more on that in our guide to water stains and mold on popcorn ceilings)
The removal method
We remove texture dry, using Festool Planex drywall sanders connected to vacuum dust extraction. No water is soaked into the ceiling — which matters more on old plaster than on drywall, because older plaster and decades of patching compound don't react well to being saturated.

Repairs after removal
This is where plaster jobs differ most:
Hairline cracks are filled and then disappear under the skim coat.
Loose sections have to be re-secured to the framing before any finishing — typically with screws and plaster washers that pull the plaster back tight against the joists. A skim coat cannot hold a section that is moving.
Badly deteriorated areas may need patching or, in the worst cases, overlaying. This is assessed on site, room by room.
The finish
Plaster ceilings are rarely perfectly flat — they were hand-troweled, and houses settle. A Level 5 skim coat evens out the surface so the ceiling reads as smooth and uniform once painted, without tearing out the original plaster.
Asbestos: test the texture — and consider the plaster too
Any popcorn texture applied before 1990 should be tested before it's disturbed. In older homes, it's also worth including a plaster sample, because some older plasters and patching compounds contained asbestos as well. Our asbestos testing guide explains how testing works in Ontario.

What this means for cost
The removal step on plaster costs roughly the same as on drywall. The difference is repair: re-securing loose sections and fixing damaged areas is extra work that depends entirely on what's under the texture. That's why we quote removal by area and assess plaster repairs on site, rather than giving a fixed number before seeing the ceiling.

Before you book: a short checklist
Find out roughly when your house was built, and whether the ceiling is plaster or drywall.
Tap around the ceiling and note any hollow, sagging or cracked areas.
If the texture went up before 1990, test it — and include a plaster sample.
Ask your contractor how they handle loose plaster, and whether repairs are included in the quote or priced separately.
Frequently asked questions
Can popcorn texture be removed from plaster without damaging the ceiling?
Generally yes, with dry, controlled removal. Cracks that show up afterwards were usually already there under the texture — removal reveals them rather than causing them.
What if part of my plaster ceiling is sagging?
It has to be re-secured or repaired before the ceiling is finished. A skim coat over loose plaster will crack again as the section keeps moving.
Is it better to cover old plaster with new drywall instead?
Sometimes — when plaster is badly deteriorated across a large area. For plaster that is mostly sound, removing the texture and skim-coating keeps the original ceiling, its height and the existing trim intact.
Does a plaster ceiling take longer than drywall?
The removal itself takes about the same time. Repairs and any extra finishing coats can add time, which we confirm during the estimate once we've seen the ceiling.
