I will be widening a dryer duct hole opening that currently houses a 4" pipe & dryer duct guard (on the outside of the house of course). I wish to widen that hole from 4" to 10" (as my application calls for that size).
What type of tool(s) would I need to do this?
Just so I'm clear, using a jigsaw though would require a 10" radius that I would have to be mindful of (as opposed to using any sort of a bit where it would simply be drill 'n' go and I don't have to make sure I go any bigger than the 10"). Is that correct?
Also, using the jigsaw would only cover the wood portion. What about the brick outside the house? Because that dryer vent runs outside so the brick would have to be covered as well.
Hi Yousef, I have never heard of a residential dryer, or any other residential appliance that uses a 10" round duct as an exhaust. Maybe you could give us an idea of what it is you are trying to connect - make and model # would be a great start. A photo may help as well.
I think that any appliance that needs a duct that big is also going to need a supply of make up air - a 10" duct with the right fan attached could change the air in an 1800 sq. ft. house in about 20 minutes.
If you want to do it yourself, rent a rotary hammer drill and a long 1/2" to 3/4" bit. From the inside of the house, drill out through the blocking / rim joist / brick in the center of the cavity you want to use. From the outside of the house, use the hole you just drilled as the center for the 10" circle you want to create and mark it out. Then use the drill to make a series of holes just touching the 10" circle mark. Using a hammer and cold chisel (eye protection and gloves as well!!!) knock out the big pieces then keep working until you make it round - keep test fitting. When the hole in the brick is big enough, you can mark out the circle on the rim joist and drill a few pilot holes in that. Then a reciprocating saw with a 12" blade to finish the cut out. Keep test fitting until it all works.
Good luck with it!

This is NOT for a dryer. I have a Vortex VTX1000 inline fan that I'm venting. I've provided you a link to the manufacturers web site so you can see the actual fan and the specs. Hope the link helps you.
Just curious though; how much would YOU charge for this kind of a job? I am on a very tight budget, and some of the quotes I'm getting are quite high. Just want to see what my options are.
Sorry, the link I provided you is just to show you an enlarged image of the fan itself. If you wish to see the specs, simply visit :
Then click on "Product"
Then under "Inline Fans" click on "VTX"
Then you'll see the different models, click on "VTX1000"
You'll see the actual product description, and the specs. Unfortunately there was no direct link I could send you for this page. As you navigate to my specific model, you'll notice the URL does NOT change.
