Walls and ceilings
Drop ceiling installation cost
A 12 × 20 ft basement room in plain 2 × 4 mineral-fibre tile with two lay-in lights is about $1,312 hung by a crew — $5.47 a square foot — and $688 in materials if you hang it yourself. The 32 tiles are the part you see; what you buy by the piece is the grid they sit in: 4 main tees, 27 cross tees, 6 lengths of wall angle and 12 hanger wires, counted here the way the standard lays them out and centred so the cut tiles at the walls match. And the number to check before any of it: with 7 ft 9 in to the joists and a duct 2 in under them, the ceiling lands at 7 ft 1 in. New tiles in the old grid are $654; pressed tin $2,800; a direct-mount ceiling that loses an inch instead of eight, $1,461.

The room, the module, and how much height there is to lose
The room against the tile module gives the grid piece by piece and the border tiles; the joists and what hangs under them give the height that is left.
Wall angle, mains, cross tees, wire, tiles, and the lights dropped in.
The long way; the mains run along it.
Mains every 4 ft across it.
Fewer pieces, fewer cross tees, cheaper. The commercial look; fine in a basement.
The basic acoustic panel: fissured or fine-textured, absorbs sound, sags if it gets wet. What most basements and offices get.
LED troffers in place of tiles.
Or to the existing ceiling.
The grid hangs 3 in under it, 6 with lights.
15/16 in: the standard.
Hung on wire; lifts out; loses inches.

240 sq ft, mineral fibre, suspended, installed
$1,312
$5 per sq ft · 32 tiles · 4 mains, 27 cross tees, 12 wires · 2 lights
7 ft 1 in when it is done
8 in below the lowest pipe or duct — 6 of them because the troffers tilt up through the grid, and 7 ft 1 in left, over the 7 ft the code wants. The 32 tiles are $304; the 37 pieces of grid they sit in are $195.
Centred, not started from a wall
An exact fit: nothing cut.
3 rows of 2 × 4 panels across and 10 along, with the grid centred so the cut tiles at opposite walls match and none is narrower than half a tile. Laid out from one wall instead, the last row is whatever is left — the 4 in sliver at the far wall that every rushed ceiling has.
The same ceiling, each tile
Same room, same grid, same crew; only the tile changes.

What it costs
National average. A 20 × 12 ft room, 2 × 4 mineral fibre, plain white in a 15/16 in suspended grid, 2 lay-in lights, a new drop ceiling. Not included: the circuits to the lights, moving ducts or pipes up, soffits round beams, or a drywall ceiling instead.
A drywall ceiling on the same joists is on the drywall page; recessed cans instead of troffers on the recessed lighting page.
Worth knowing
- 240 sq ft is 30 tiles and it is also 4 main tees, 27 four-foot cross tees, 6 lengths of wall angle and 12 hanger wires: $194 of grid against $304 of tile. The grid is the counted product; the tile is what you see.
- Centred on the room, the border tiles come out 4 ft wide across and 2 ft along — the room is an exact number of tiles both ways, nothing cut. Started from one wall instead, the last row would be whatever is left, which is how a ceiling ends up with a 4 in sliver at the far wall.
- The grid drops 8 in below the lowest thing up there — 6 in, because the troffers have to tilt up through it, leaving 7 ft 1 in of ceiling. Over 7 ft: the code is happy.
- 2 lay-in troffers take the place of 2 tiles and want a box and cable above each; the electrical is priced here as the fixture and the hour to hang it, not the circuit.
- Mineral-fibre tile sags after one leak and stains after one damp summer; under a bathroom or in a wet basement, vinyl-faced or PVC is the tile that stays flat.

Counted in grid, not tiles
The short version
- 12 × 20 ft, plain tile, two lights: $1,312, $5.47 a square foot. $688 of materials yourself.
- 32 tiles sit in 37 pieces of grid on 12 wires. The grid is the counted product.
- It lands at 7 ft 1 in. Check that before anything else; the code wants 7 ft.
- Tiles only in the old grid: $654. Tin: $2,800. Direct-mount, no drop: $1,461.
The tile is what you see and, on a plain ceiling, about a quarter of what you pay. What you actually buy by the piece is the grid: main tees 4 ft apart across the room, hung on 12-gauge wire every 4 ft; 4 ft cross tees between them every 2 ft; a 2 ft cross tee splitting each bay if the tiles are 2 × 2; wall angle screwed level round the whole perimeter for the grid to rest on. For a 12 × 20 room that is 6 lengths of angle, 4 mains, 27 cross tees and 12 wires with a screw eye each, and the calculator counts them the way the standard lays them out, then centres the tile module so the cut tiles at opposite walls match.

Dropped in inches
A suspended ceiling has to hang far enough below the lowest thing up there to get a tile in and out: 3 in, or 6 in where a lay-in troffer has to tilt up through the grid. In a basement with 7 ft 9 in to the joists and a duct 2 in under them, that lands the ceiling at 7 ft 1 in, which clears the code’s 7 ft for a habitable room. With 7 ft 6 in and a 4 in duct it lands at 6 ft 8 in, which does not — and that is the room a direct-mount ceiling exists for: track screwed to the joists, the same tiles clipped an inch below, 7 ft 5 in left, and no lift-out access to anything above.

The tile is the only line that moves
The grid does not care what sits in it, and neither does the crew: the same 37 pieces and the same 9.6 hours whether the tile is plain mineral fibre or pressed tin. So the tile is the whole difference between a $1,312 ceiling and a $2,800 one. Mineral fibre absorbs sound and hates water; a textured or tegular tile hides the grid and reads as a finished ceiling; vinyl-faced wipes clean and stays flat over a laundry; PVC is waterproof outright and the tile for under a bathroom; tin is a ceiling of its own and costs like one.

Hanging it
In order
- Everything above the ceiling done first: cable to the light boxes, valves, the duct that was going to move.
- The finished height marked all round: 3 in under the lowest pipe, 6 under the lights, and over 7 ft.
- Wall angle screwed to the line, level all the way round, corners mitred or overlapped.
- The layout centred: borders equal at opposite walls, none under half a tile. Chalk the first main.
- Screw eyes into joists every 4 ft along the first main; wires cut long, three turns at each end.
- First main hung dead level and dead straight — every other piece follows it.
- Mains every 4 ft, cross tees clipped, squared with a tile before the wires are trimmed.
- Tiles in from the middle out, cut tiles at the walls with a utility knife against a straight edge, troffers last.
What goes wrong
01Not measuring the height first
A ceiling that lands under 7 ft in a habitable room is a room that does not pass, and it is found out after the grid is up.
Instead — Floor to joists, less the lowest duct, less the drop. Direct-mount or move the duct if it is short.
02Starting the grid at a wall
The far wall gets whatever is left: a 4 in sliver of cut tile the whole length of the room.
Instead — Centred, with equal borders of at least half a tile.
03Wall angle out of level
Everything rests on it; a quarter inch out at one end shows in every tile along that wall.
Instead — A laser line, and the angle screwed to it, not to the last piece.
04Wire on drywall screws or the old ceiling
The grid and tiles weigh a pound a square foot, more with lights. Anchors pull.
Instead — Screw eyes into the joists, every 4 ft on every main.
05Mineral fibre under a bathroom
One leak and the tile sags; one damp summer and it stains.
Instead — Vinyl-faced or PVC where there is water above or around.
06Tegular tiles for the wrong grid
A 9/16 in tegular tile does not drop into a 15/16 in grid, or the other way, and they do not return once cut.
Instead — The grid face measured before the tiles are ordered.
07Lights after the grid
The box and cable are then run from a ladder through a 2 ft hole.
Instead — Boxes and cable above first; troffers plug in last.
08Trimming the wires before squaring
A grid that is not square shows in the tiles, and cannot be pulled square once the wires are cut short.
Instead — A tile in every fourth bay as a square, then the wires trimmed.
- 01Measure the roomLength and width in feet. The mains run the long way, 4 ft apart across the width.
- 02Measure downFloor to the joists, and how far the lowest duct or pipe hangs below them. The grid goes 3 in under that, 6 in if there are lay-in lights.
- 03Check the height that is left7 ft in a habitable room. Short of it, a direct-mount ceiling loses an inch instead, or the ducts move up first.
- 04Pick the module and the tile2 × 4 is cheaper and reads as an office; 2 × 2 is twice the tiles, an extra cross tee a bay, and reads as a room. The tile grade is the only line that changes the price much.
- 05Count the grid, not just the tilesWall angle from the perimeter, mains from the rows across, cross tees from the bays, a wire every 4 ft on every main. The calculator does it piece by piece.
- 06Centre the layoutBorders equal at opposite walls and at least half a tile. The cut tiles are counted and the 5% is for them.
A drywall ceiling on the same joists loses half an inch instead of eight, absorbs nothing, and gives no access. The drywall page prices it by the sheet on the same room.
The other basement ceiling- Drop, suspended, acoustic ceiling
- The same thing: a metal grid hung on wires below the joists with tiles laid into it. Lifts out for access; costs inches of height.
- Main tee
- The 12 ft load-bearing runner, hung on wire every 4 ft along and spaced 4 ft apart across the room. The cross tees clip into it.
- Cross tee
- The 4 ft piece between mains every 2 ft, making the 2 × 4 bays; a 2 ft piece splits each bay for a 2 × 2 module.
- Wall angle
- The L-shaped moulding screwed to the walls at the finished height. The grid rests on it round the edge.
- Hanger wire
- 12-gauge wire from a screw eye in a joist to a main, every 4 ft, wrapped three turns. What holds the ceiling up.
- Border tile
- The cut tile at the wall. Centring the grid makes opposite borders equal and keeps each at least half a tile wide.
- Tegular edge
- A tile with a recessed edge that drops below the grid face and hides most of it. Cut for a 15/16 or a 9/16 in grid, not both.
- 15/16 vs 9/16 in
- The width of the grid face that shows. Narrow grid shows less and costs about a third more.
- Lay-in troffer
- A flat LED fixture the size of a tile that drops into the grid in its place. Needs a box above it and 6 in of clearance to tilt in.
- Direct-mount
- Track screwed straight to the joists or the old ceiling, with clips that hold the same tiles an inch below. No wires, no drop, no access.
- Ceiling height
- The code's 7 ft in a habitable room, 6 ft 4 in under a beam or duct, 6 ft 8 in in a basement that is not habitable space. The drop is measured against it.
- NRC
- Noise reduction coefficient: how much sound a tile absorbs, 0 to 1. Mineral fibre is 0.5 to 0.7; vinyl-faced and PVC much less; tin none.
Common questions
- How much does a drop ceiling cost to install?
- About $1,312 for a 12 × 20 ft room — $5.47 a square foot — in plain 2 × 4 mineral-fibre tile with two lay-in LED troffers, hung by a crew: 32 tiles, 4 main tees, 27 cross tees, 6 lengths of wall angle and 12 hanger wires. Without the lights it is $1,044; in 2 × 2 tile $1,386; a 30 × 25 ft space with six lights $4,215, or $5.62 a square foot.
- How much is a drop ceiling per square foot?
- $5.47 installed for plain mineral-fibre tile with a couple of lights, $4.35 without them; $6.6 for a textured or coffered tile, $7.14 vinyl-faced, $11.67 in pressed tin. Materials alone are $2.87 a square foot for the plain tile. The grid and the labour are the same whatever the tile; the tile is the only line that moves.
- How much does it cost to replace ceiling tiles only?
- About $654 for the 12 × 20 room — 32 plain tiles and an afternoon, up to the crew's minimum — against $1,312 for grid and tiles. Check the grid face first: a 15/16 in grid takes any lay-in tile; tegular tiles are cut for 15/16 or 9/16 and do not swap. Tearing out the old grid and hanging a new one is $1,512.
- How much height does a drop ceiling take?
- 3 in below the lowest thing up there to get a tile in and out, 6 in if there are lay-in lights, because a troffer tilts up through the grid. In the example room the ducts hang 2 in under the joists at 7 ft 9 in, so the ceiling lands at 7 ft 1 in. The code wants 7 ft in a habitable room and 6 ft 8 in in a basement that is not one; a 7 ft 6 in basement with a 4 in duct lands at 6 ft 8 in, and that is when the direct-mount ceiling — 7 ft 5 in — earns its place.
- What is a direct-mount ceiling?
- Surface track screwed to the joists or the existing ceiling, with clips that hold the same 2 × 2 or 2 × 4 tiles an inch below it. No wires, no grid, and no drop: $1,461 for the room against $1,312 suspended, with the track in place of the grid. What you lose is the lift-out — a leak or a cable above it means tiles down and clips off — so it is the answer for a low ceiling, not a preference.
- 2 × 2 or 2 × 4 tiles?
- 2 × 4 is 32 tiles and 27 cross tees for the room: $1,312. 2 × 2 is 63 tiles and 30 more cross tees to split the bays: $1,386. The 2 × 4 reads as an office and sags more between supports; the 2 × 2 reads as a room, which is why houses get it and basements often do not.
- How much does a tin ceiling cost?
- About $2,800 for the 12 × 20 room in pressed-steel lay-in panels — $11.67 a square foot, 64% of it the tiles — in the same grid as any other tile. PVC panels in a tin pattern are $1,968 and waterproof; real tin dents, sounds like tin, and looks like nothing else.
- Which tile for a basement or a bathroom?
- Not plain mineral fibre where there is water: it sags after one leak and stains after a damp summer. Vinyl-faced tile ($1,712 for the room) wipes clean and stays flat; PVC panels are waterproof outright and the tile for under a bathroom or in a basement that floods. Mineral fibre is the one that absorbs sound, and the one for a media room or an office.
- Can I install a drop ceiling myself?
- Yes — it is the most forgiving ceiling there is. Materials for the 12 × 20 room are about $688 with two lights, and it is about 24 hours, most of them getting the wall angle level all the way round and the first main tee straight; everything after clips into those two. A laser level, a second person for the mains, and the layout centred before the first screw eye goes in.
- How is the grid counted?
- Wall angle: the perimeter in 12 ft lengths. Mains: one every 4 ft across the width, in 12 ft lengths along the room. 4 ft cross tees: one per bay between the mains, every 2 ft along. 2 ft cross tees: one per bay for a 2 × 2 module. Wire: one every 4 ft on every main, about 5 ft each, in 100 ft rolls, with a screw eye per wire. For the 12 × 20 room that is 6, 4, 27 and 12, and the calculator changes them with the room.
- Where do the cut tiles go?
- At the walls, and equal on opposite walls, with the grid centred so no border is narrower than half a tile. The 12 × 20 room fits 2 × 4 tiles exactly both ways — 0 cut — which is rare; a 10 × 10 room is 3 rows across with 3 ft borders and 5 along with none. Started from one wall instead, the far wall gets whatever is left.
