Quick answer
Blinds bang because moving air pushes the slats and swings the loose bottom rail into the glass or the frame. For a free quick fix, tighten the brackets, add a little weight to the bottom rail and raise the blind when the window is open. To stop it for good, pin the rail with hold-down brackets (tension clips), or add weights on light blinds, so the blind cannot swing even in a stiff breeze.
Free fix vs. permanent fix
Tighten, weigh down and raise it
- Snug the mounting brackets so the whole blind stops shifting
- Tape two or three flat washers to the bottom rail
- Raise the blind fully whenever the window is open
- Move any fan or vent that blows straight at it
How long it lasts: A few days to a few weeks. Tape loosens in sun and heat, and a strong gust still swings a free rail.
Blind hold-down brackets (tension clips)
The banging is the loose bottom rail swinging. A hold-down bracket screws to the frame or door and clips the rail so it cannot move. Unclip it to raise the blind. Weights are the no-drill option for lighter swaying.
How long it lasts: Years. The bracket pins the bottom rail to the frame or door, so wind cannot swing it.

Why it happens
Open windows and doors
Moving air pushes light aluminum or vinyl slats off the glass. When the gust drops, the blind swings back and bangs.
A free-swinging bottom rail
Most blinds hang from the top only. Nothing holds the bottom, so each gust swings the rail like a pendulum.
Blinds on a door
A blind on a door window or a patio door swings with the door as well as the wind, and the rail slaps the glass every time the door moves.
Loose hardware
A headrail that is not seated in its brackets, or brackets with loose screws, lets the whole blind shift and rattle.

Do these in order, starting with the simplest.
-
Snug the mounting brackets
Tool used: ScrewdriverPress the headrail up into the brackets, close the clips and tighten any loose screws. A blind that sits firmly at the top rattles less.
-
Add weight to the bottom rail
Tool used: Flat washers or coinsStick two or three flat washers or coins to the back of the bottom rail, near each end, with strong tape. A little extra mass cuts the swing on mild breezes.
-
Raise the blind when the window is open
A blind pulled all the way up cannot swing. On breezy days, raise it before you open the window.
-
Check what is blowing on it
Fans, air conditioner vents and radiators that blow across the blind make it sway too. Move them or aim them away from the window.
-
Pin the rail down
Tool used: Blind hold-down bracketsMount a hold-down bracket on the frame or door under each end of the bottom rail and clip the rail to it. Use the screws or adhesive that come with it. Never hold the rail down with a loop of cord.

When free fixes aren't enough
Taped washers help on mild breezes, but tape lets go in sun and heat, and a strong gust still swings a free rail. If the blind hangs on a door that opens and closes, the rail also slaps the glass with every swing. A hold-down bracket removes the movement instead of damping it. Go easy on weights with heavy wood or faux-wood blinds, because extra load strains the cord locks and lift cords. And if the blind will not stay up in the first place, that is a cord lock problem, not a wind problem.

Blind hold-down brackets (tension clips)
Fixes: a bottom rail that swings and bangs in a breeze
Look for: Made for the type of blind you have, such as horizontal mini blinds; A screw-in or strong adhesive mount that suits your frame or door; An easy unclip, so you can still raise the blind.
- Who it's for
- Anyone with a window that stays open, or a blind on a door.
- Honest downside
- You rent and cannot drill. Choose the adhesive style, or use weights instead.
Blind weights
Fixes: light swaying and bumping on lightweight blinds
Look for: The weight listed in ounces, so you can match it to your blind; A design for your blind type, such as vertical vanes or a horizontal bottom rail; A clip-on or slide-in fit, with no drilling.
- Who it's for
- Renters, and anyone with vertical blinds or light aluminum or vinyl blinds.
- Honest downside
- Your blinds are heavy wood or faux wood, or the wind is strong. Weights strain the lift mechanism, and a gust still moves a weighted rail.

How we picked: How we picked: this page is based on window covering care guides, child safety guidance on blind cords and the instructions from blind accessory makers, and the problems and fixes people report in reviews. We do not test products by hand.
Which fix for which blind
- Horizontal mini blinds (aluminum or vinyl): hold-down brackets, or a little weight on the bottom rail.
- Vertical blinds on a patio door: bottom weights or a link chain that keeps the vanes in line.
- Blinds on a door window: hold-down brackets mounted on the door.
Cords and children
Looped and dangling blind cords can strangle small children. Keep pull cords wrapped on a cleat above a child's reach, and do not add any loose cord to hold the blind. For homes with babies and toddlers, cordless blinds are the safer choice.
What to skip
Cord loops and heavy objects on the sill
Do not tie the rail down with a loop of string, cord or a bungee. Loops are a strangulation risk for small children and pets. A heavy object on the sill does not hold the bottom of the blind either, since the rail swings above it.
