Every house with a stove or even microwave oven usually has an exhaust vent that leads to the outside and at the end of this vent is usually where we find our problem.
With a simple application of this thicker and stronger weather stripping in just the right places we can eliminate or at least drastically reduce that noise. Below are some of the items I used to fix this problem... FYI I used the 3/4" wide and 3/16" thick foam weather tape. This provided the best results from my experience.

Well darn 😂 it’s 10 pm right now and I was hoping for a quick fix because we have a storm and people sleeping in the noisy room. But I will be saving this for later use
Aww man. I feel ya on that. Nothing worse than hearing that flapping through the vent at night.
Very helpful. I will try the fix for the noise that is coming from the vent that is in one of the cabinets.
It’s helped a ton with out vent. On the windiest days is almost non existent now
haha this is awesome, as you know I just bought my new house and thats all I hear is that darn banging. I''ll be doing this asap. thanks again brother.
Yup! It works pretty well. I added another piece or two on the outside around the hinge area. It helps it from rattling and provides more spring/pressure down
@@FortKnoxCo haha just realized that I need a ladder, another thing to add to the list for Black Friday/ cyber Monday
@@poweredbyeb lol. It’s always good to have a few ladders hangin around.
@@FortKnoxCo 😂🤣
@@FortKnoxCo vent flappers have been annoying and notifying us about high winds for decades. 10 year old me hated the sound of loud slamming exhaust vent flappers 😂
Thanks so much it help heaps 👌🏽
Your very welcome
Life saver. Have had a terrible noise for months after the house was repainted. I foun the vent that flaps!
Can't believe that little vent made the racket it did in my kitchen.
That’s awesome! Yeah it’s crazy how loud and annoying that little thing can be.
@@FortKnoxCo I’ve been in many homes in windy regions and those little flaps despite weighing grams make so much racket when those winds blow. The pressure rushing in and out of the opening causes this.
@@charlesrodriguez7984 I agree. It always seems to be a problem spot.
@@FortKnoxCo my house has roof vents that open very easily in wind and then slam shut making a strange clicking and tapping sound. Only on the west facing exhaust vents that have unobstructed air flow to inside however.
This video was really helpful and such a simple idea. Question: what did you put on the outside in the two corners along top edge? In the video you said you would be putting more foam tape but when you showed finished project it looked like some kind of making tape?
I just used more of the same foam tape. I placed a few small pieces on the outside over the hinge to damper the movement and help with the rattling between the two pieces of metal touching. The hinge seems to be half the problem with the noise. It metal on metal with a lot of movement. So by placing a few pieces of the foam there it gives it some resistance and keeps it in a constant contact state for the most part.
Your video was very helpful. I look forward to trying this on our new exhaust vent. Could you recommend where I can get a critter grill for a new 8" stove exhaust. It's just wide open at this point and flaps all day with the wind. It is brand new but was obviously just cheap and available. Thank you!
Aww man that’s no good if they didn’t have some type of grill in that. 8” is a good sized vent opening. They do sell some small mesh panels at Home Depot and Lowe’s that you could cut slightly bigger than the 8” opening, cut slits or tabs around the outer perimeter And bend them enough to wedge and slide into the opening down into the tube.
Those meshes are usually found in the air ducting or roofing areas or the metal mesh will be in another area where they sell pieces of angle iron and metal mats and tubing. not listed as air duct mesh obviously but can be repurposed for it.
The funny thing I’ve noticed is that in roof vents with dampers they aren’t as loud as wall vents when the wind is blowing. However a lot of bathroom fans have a damper inside at the fan that can be quite noisy especially if the wind is strong. Some people are more annoyed with the sound of flaps closing in vents but I don’t mind it. But good to know these tips for anyone who might be annoyed with their noisy vent flap endeavors.
Yes! The ones in the bathroom fans are hard to mess with and quiet up. It can be done sometimes but you just can’t mess with them too much or else you start to affect the air flow.
@@FortKnoxCo that’s exactly why I left mine alone. Some companies like Hampton bay have fans with a quieter fan motor and damper. I have cheap builder grade nutone fans in my house and one was replaced with a Hampton bay fan and that fan is quite similar to the old one. the damper is quieter when it’s slamming shut but i can of course still hear the air blowing in from outside.
@@charlesrodriguez7984 you’d think by now a company would just improve the design. There’s a lot of home owners or builders that could upsell that feature and i think people would want it.
@@FortKnoxCo yeah. I don’t think it’s that important for them and many people just leave them alone and ignore them.
@@FortKnoxCo it’s almost Impossible I think to make the damper much more quiet than they are now because it’s hard plastic on plastic for most of them. Though I’ve lived in an apartment that had an exhaust fan in the secondary bathroom that was an extremely loud tap or slam sound whenever the wind blew at the vent. It was a metallic sound.
The racket we have is coming from the butterfly damper just above the range hood. The wind blows across the roof vent, and creates a vacuum, which flaps the damper. It's in a round pipe, within a square stack, and I can't get at it.
I get what you’re saying. That is a hard location to get to without being pretty invasive. Is there anything you can do to the vent extinguisher on the roof that can slow down or dampen the air flow? Maybe adjusting the type of cover over the vent or angle of the cover? I know some vents have a makeshift hood/roof rap over the opening and it almost catches the wind. Maybe there’s something there you can add or adjust to stop the vacuum effect it’s having
Great video. Just wondering, if the flap never fully shuts, will it not allow an easier entry for the critters?
The flat should still close and sit on the foam you install. You wouldn’t want to put too thick of foam to cause the flap to stand off. But also as far as critters, there’s usually a screen either at the entry point or somewhere down the line to prevent this.
You can use a very thin foam cushion. The main purpose is to just eliminate that metal on metal

@@FortKnoxCo Thank you, appreciate this.
@@brigittehp1589 No problem at all
I have this issue and it's terrible. I live in an apartment building on the top floor and the stove hood fan flaps horribly. And driving me crazy! Landlord will not fix it ,says there's nothing he can do ..so guess what? I'm going to show him this video!
Any ideas how to fix this outside my condo on the 12th floor?
You’ll need to look around the building, possibly around the outside wall, look in the area near you laundry or stove cuz they could have made a short run up an exterior wall to vent it. If your the top floor it could be vented on the roof.
But a lot of condo/apartment buildings vent all around the exterior wall. You’ll see an angled hood vent. If it is up on the 12th floor you may not be able to mess with the exterior vent. But may be so to bring up to the building maintenance. Point it out to them and help them diagnose and suggest the solutions. They may try and fix it.
The microwave clanging problem is in a condo where I have no access to the outside of the vent. I don't use the fan but was told to reverse the fan itself directly to vent inside rather than out. What do you think?
I would not recommend that. That could be a safety hazard for sure if you ever need to vent out the space and have an exit point for smoke or fumes. Not that it will happen, but just in case it ever does, that would not be a good thing to have that fan keeping all the air in.
If you don’t have access to where the fan exits your building, and you cannot see it anywhere on the outside of your building, or might have to get to it with a ladder, I would try reaching out to the maintenance or whoever your management system is and see if they can get to the Exit point of your vent and do the same process of dampening the flap because it’s making excessive noise. It should be somewhere on that building where it exits and there’s a flap that controls the airflow. So it’s just a matter of getting to it yourself or whoever has permission to.
Thanks for the tip. As of this morning it appears it might be a problem with a vent on the microwave itself. Who knew? I'll find out when the repair guy gets here next week.
@@mariettamayberg7009 awesome. I hope they get it figured out
Ours is hidden under the deck about 15' from the couch. The tapping can't be heard outside, but sounds like a distant neighbor hammering, then stopping every time I open the door. 😤😠🤬 Finally found it.
Well That’s good you found the problem. But man what an inconvenient location. I hope you get it figured out. I know that tapping noise can be annoying
What about if it's on the third story of a house
You should be able to do the same thing, but I think this would obviously involve a ladder now. As long as you can get to wear that vent is whether it is on the wall or sometimes on a roof vent. You can apply the same technique of dampening the metal on metal contact to reduce the noise greatly.
No metal contact, and it doesn';t seall any more, so dust and cold air will come in
You want to make sure is still sits down flat, so not using too big of a gasket will help. Or adjusting the door/hinge if you can to allow it to sit flat. The main goal is to just not have the metal on metal contact. Some nicer designed flaps have a little more weight to them and they sit with some slight pressure to help create the seal when the vent fan isn’t in use.
I have tried this a few different ways. If the door is fully open....no banging. The outside is fully padded but something inside is making the banging noise
There is sometimes a flap just inside of the exhaust vent above your stove, usually a one way type of opening to allow air out but not back in. That sometimes can be flapping around. Depending on how far you pipe goes from inside to outside there may be another flap that you need to dampen
Like bathroom fans, there’s usually two dampers in a hood vent system because the roof and wall cap flaps aren’t perfect seals and often and very easily lift up in strong winds. You may want to dampen that as well.
My issue is the vent flap stays open as the wind blows then I have wind blowing right down into my house.
Is this after you’ve put the foam tape on it? Or your saying you problem before fixing anything is that your flap is just sitting open letting air in?
@@FortKnoxCo it has foam tape on it. The vent flap just stays open because the wind lifts it and then the wind comes rushing into the house…I think the contractor didn’t install a damper.
@@MaryOKC okay yeah. Usually there’s something, if it’s a upgraded type of product, that gives it some down pressure to keep closed when not in use. Most are just a flap on a hinge. That’s why the wind grabs it so easily. But in our case I put some foam tape on the outside over the hinge area in a few spots to give it some resistance and give that down pressure to stay closed. You might try that and see if it helps push on it to stay closed but not too much to not let it open when you run your exhaust fan.
@@FortKnoxCo I can try that but the winds here are pretty fierce (Oklahoma). LOL!!! 😂
@@MaryOKC haha. Yeah. Might be worth a try but I could see the winds maybe winning that one. Some upgraded models have a spring incorporated. So that may be an option. Somehow installing a spring or swapping out to a flap that has one already.
Very helpful. Thank you!
Your very welcome 🤙🏼🤙🏼
I thought i had roaches and i was looking for weeks it was driving me crazy !
lol. Aww man I bet that was nerve racking. Yeah it can drive you crazy not knowing where “that noise” is coming from.
But now you let the air in even more. They have inclosed ones that don't let drafts in.
If done correctly you can damped the surface that the flap hits without keeping the flap open. It should still rest flat but not be metal on metal. I also put some foam on the outside at the top by the hinges. Putting downward pressure on the flap also helping keep the flap closed unless air is being pushed out of the hole by the fan.
I wonder if you could put a small bead, very thin, of silicone on the perimeter. Thinner than the tape, to avoid letting too much air back in, but a barrier from metal in metal.
@@stephenrew2545 that’s possible. You’d have to let that silicone dry before letting the flap back down obviously. You could use different material to accomplish the same thing. Main thing is that you don’t have metal on metal contact.
useless workers 🎉❤ thanks
I appreciate that. Wish they had better engineering on these kinda vents. Seems so basic and always a Headache.
worse than stypit
Agreed
