How to Remove Blinds From a Window (Roller, Venetian & Vertical)
Taking down old blinds looks intimidating, but almost every window covering uses the same idea: the blind sits in a couple of brackets, and those brackets release in one of three ways — a sliding tab, a snap-open gate, or a clip you press. Once you know which one you have, the whole job takes a few minutes per window and rarely needs more than a screwdriver.
The part most people get wrong isn't the removal — it's the wall. Rushing the headrail out, prying with a metal tool, or yanking screws can chip drywall, crack plaster, or leave holes that don't line up with your new blinds. In older Calgary homes (Mount Royal, Inglewood, Bridgeland) you'll often find plaster or lath behind the trim, which behaves differently than modern drywall.
This guide walks through removing roller, venetian/faux wood, and vertical blinds without damaging the wall, plus how to patch holes and prep the opening for a clean replacement. And if you'd rather skip it entirely, Sunleo removes and disposes of your old blinds free when we install new ones.
What you'll need (and how to find the brackets)
Before touching anything, identify how your blind is mounted. Look at the top of the window. An inside mount sits inside the window frame with small brackets tucked at each top corner. An outside mount is screwed to the wall or trim above the opening, usually on a wider headrail. The brackets are the metal or plastic pieces holding the headrail — everything releases from them, so you almost never start by removing screws.
Gather a basic kit so you're not stopping halfway through. Most blinds come down with just a flat-head and a Phillips screwdriver. Keep a small container nearby for screws so they don't roll into a heat vent.
A quick safety note for older or motorized units: if the blind is hardwired or plugged in for motorization, unplug it first. For corded blinds, lower the cord cleat or wand out of the way so nothing snags as you lift the headrail clear.
- Phillips and flat-head screwdrivers (covers ~90% of brackets)
- A step stool — work level with the brackets, never reach up at an angle
- A small bowl or magnetic tray for screws and bracket parts
- A putty knife and lightweight spackle/filler for patching
- A pencil to mark new holes if you're replacing same-day
- Optional: cordless drill with a screwdriver bit for outside-mount screws
How to remove roller and zebra (day-night) blinds
Roller and zebra blinds share the same headrail design, so they come out the same way. The fabric tube rests in two end brackets — one with a pin, one with a clip or pawl. You don't unscrew anything to free the blind itself.
Start by rolling the blind all the way up so the fabric is wound tight and out of your way. Support the tube with one hand so it can't drop. Most brackets release at the front: look for a small lever, tab, or hinged gate on the bracket facing you. On clip-style brackets, press the tab and tilt the bottom of the headrail toward you, then lift the tube out of the opposite (pin) side. On older spring rollers, the flat pin end usually slides straight out of a slotted bracket once the round end is lifted clear.
If the headrail won't budge, don't pry against the wall. Re-check which end is the pin and which is the clip — forcing the wrong end is what cracks brackets and gouges drywall. Once the tube is out, the empty brackets stay on the wall; remove their screws last so you keep full control of the headrail until it's safely down.
- Roll fully up and keep one hand under the tube at all times
- Release the front clip/gate, tilt forward, then lift off the pin end
- If a Chinook has left grit in the bracket, brush it out before reseating anything new
- Unscrew the empty brackets only after the blind is set aside
How to remove venetian, faux wood and aluminum blinds
Horizontal slat blinds — faux wood, real wood, and aluminum — hang from a metal headrail held by hinged "box" brackets at each end (and sometimes a centre support on wide windows). These brackets have a small front door that flips open.
First, raise the slats fully to the top and rotate them open so the headrail is light and easy to handle. Locate the hinged cover on the front of each bracket. Use a flat-head screwdriver to gently flip it open — it pivots up or to the side. With both end gates open (and any centre support released), the headrail drops free: tilt the front edge down slightly and slide the rail forward out of the brackets. Support the full weight, especially on faux wood blinds, which are heavier than they look.
For wide windows, open the centre bracket last so the rail doesn't sag and bind. Aluminum slats bend easily, so don't use the slats as a handle — always carry the unit by the headrail and bottom rail together.
- Raise slats fully and tilt open to lighten the headrail
- Flip open the hinged front gate on each end bracket with a flat-head
- Release any centre support, then slide the rail forward and down
- Carry by the rails, never by the slats — aluminum and faux wood dent
How to remove vertical blinds and patio-door panels
Vertical blinds (common on Calgary patio doors and tall basement windows) work the opposite way of horizontal blinds: the vanes hang down from carriers inside a long headrail, and the headrail clips into brackets along the top.
Work in two stages. First, remove the vanes: rotate them flat (open), then gently push each vane up into its carrier clip and tilt it toward you — they unhook one at a time. Set them in order if you plan to reuse or donate them. With the vanes off, the headrail is light. Then release the headrail: most brackets have a tab you press while rotating the back of the rail down and out, or a snap-clip that opens with a flat-head. Support the rail along its length as it comes free so it doesn't twist.
On very wide patio doors there may be three or more brackets — release the end ones first, then the centre. Once the headrail is down, the brackets remain screwed to the wall or ceiling; remove them last and keep the screws if the holes might be reused.
- Remove vanes first: rotate open, lift into the clip, tilt out one by one
- Press the bracket tab and rotate the headrail back and down to release
- Release end brackets before centre brackets on wide patio doors
- Keep vanes in order if donating — many Calgary reuse centres accept them
Protect the wall and patch the holes
This is where a tidy job is won or lost. With the blind out, you're left with empty brackets and, after those come off, a handful of screw holes. How you finish them depends on whether you're replacing the blinds the same day.
If new blinds are going up immediately and they're the same width, leave the existing brackets in place where possible — reusing the same screw holes means zero patching. If the new blinds are a different size or style, remove the old brackets and back out the screws by hand for the last few turns to avoid blowing out the drywall around the hole. In plaster homes, turn slowly; plaster can crumble if a stripped screw is forced.
To patch, push a small amount of lightweight filler into each hole with a putty knife, scrape flush, let it dry, and lightly sand. Wipe Calgary's fine dry-climate dust off the wall first or the filler won't grip. For anchors in drywall, pull them straight out with pliers rather than pushing them through — a pushed-in anchor leaves a bigger hole behind the wall. Touch up with matching paint once dry.
- Reusing the same blind width? Keep the brackets and skip patching entirely
- Back screws out by hand for the final turns to protect the hole edges
- Pull wall anchors out with pliers — never push them through
- Dust the wall before filling so spackle adheres in Calgary's dry air
- Let filler fully dry, sand flush, then touch up paint
Prepping the window for new blinds — or let us do it
Once the wall is clean and patched, the opening is ready to measure for a replacement. A few minutes of prep now prevents a crooked or too-narrow fit later. Wipe down the inside of the frame, check that the old screw holes won't interfere with where new brackets need to land, and confirm the frame is square — older Calgary homes settle, and a window that's out of square changes how an inside-mount blind sits.
Get accurate measurements before you order anything. For inside mounts, measure the exact width at the top, middle, and bottom and use the narrowest; for height, measure both sides. Even a few millimetres matters with custom blinds, and our high-altitude UV and big temperature swings make a snug, gap-free fit worth getting right the first time.
Honestly, removal and prep is the easy part to hand off. When Sunleo installs your new custom blinds, our installer takes down and disposes of the old ones, patches the bracket holes, and mounts the replacement squarely — included, not extra. If you're already this far into the job, a free in-home measurement is the simplest way to make sure the new blinds fit perfectly and the wall looks untouched.
- Wipe the frame and confirm it's square before measuring
- Inside mount: measure width at top/middle/bottom, use the narrowest
- Note where old holes sit so new brackets land on solid material
- Sunleo removes, disposes, and patches free when we install new blinds
