Do Americans in dense city centers vent their dryers directly outdoors?

You're missing the big picture here While your concern about lint causing pollution is at least reasonably admirable, the reason European dryers have all that filtering instead of a vent isn't for the ...

Is it ok that my dryer vents into a porch attic?

Yes, that's a problem! Depending how long it's been set up like that, you may already need to replace the whole porch roof, and hope it hasn't rotted the wall framing too much. Dryer exhaust needs to ...

Is it Ok to mount a bathroom extractor fan at floor level?

First off, you misunderstand the intention of the extractor fan. It is not to remove hot air. It is to remove moisture from the air, and that's done to help protect against mold and mildew buildup. ...

Using old vent pipe as TV antenna

There is a LOT that goes into making an antenna work properly. That's why the old-school TV antenna has so many little rods sticking out the sides - they have to be certain fractions of the wavelength ...

Cleaning a long dryer vent that is completely behind drywall

Perhaps a leafblower (or two?) might clean it out a bit? Also maybe get advice on how to make the outside vent area fire resistant if the tube does catch fire.

Crushed Aluminum Dryer Vent

It is held on by duct tape or metal foil tape (metal foil preferred) and/or a simple clamp with one screw. Temporary fix is to remove from wall, clean out lint, push back into shape and reattach. Do ...

Trying to replace bathroom vent, but housing is stapled to the rafter

You've already pretty well mangled the housing and you're planning on replacing the whole thing anyway, so just go to town hacking at it. A pry bar, a hammer, a pair of tin snips, and some sturdy ...

Can the exhaust duct of an ERV vent *into* the garage?

I am sure it would be against code. If it isn't always running and your ERV doesn't have a damper on the exhaust then you've introduced a nice path for CO to enter from your garage into your house. I'...

How can I seal a foundation vent?

I'd suggest that the problem is the flower bed, not the vent. Grade should be reduced and sloped properly to prevent the problem. Consider rain gutters in the area. You could also switch to a flower ...

Drywall surrounding vent no longer supports screws;

My default fix would be just to put in some type of anchor. Given the damage and the fact this is on a ceiling, I'd be inclined to use a screw-in type anchor, because they hold on to a larger area and ...

How do I attach my vent tube to the dryer securely?

Trying to replace bathroom vent, but housing is stapled to the rafter

A small prybar, cold chisel, or a screwdiver you don't like much (this is screwdriver abuse) can be driven under the staple to get it moving. There appears to already be space there. Even a large nail ...

How can I mitigate the effect of a long dryer vent duct on performance?

Add both a secondary lint trap and a dryer duct booster fan. Fantech and Tjernlund are a couple brands to help you start your search. Also, replacing any easily accessible flexible duct with rigid ...

Crushed Aluminum Dryer Vent

Both other answers are good, but there's another solution. The vent is an accordion. Not a good one, so you can really only lengthen it. Shortening it take a bit of skill, patience, time, and luck. ...

Is it ok that my dryer vents into a porch attic?

The whole point of a vent for a dryer is to take away the moisture contained in the air used to dry the wet/damp items in the dryer. That moist air will go to anywhere cooler than itself. So if it can'...

Does this roof vent flashing need replacement?

That mesh is not meant to be used on the roof as it has no function there. One would need large amount of roof sealnt to close all the holes. It needs to be replaced with non porous sheet metal.

Vent kitchen hood vent to roof turbine vent?

I don't know where you live, but something to consider is that you're dumping warm, moist air into a potentially cold zone. So some of that air can/will condense in there in winter. Since attics tend ...

In my personal opinion, this type of duct is NEVER a good idea for a dryer vent. Lint sticks to the inside much more than smooth metal. It's virtually impossible to clean effectively, without ...
