    We are building a patio and at the moment the dryer duct in located where the patio steps will go.

    As with most counties, our county HAS building codes regarding the maximum length of dryer ducting.

    So I want to run the duct to the front of the dwelling (client is cool with this).

    the front of the house is brick.

    Can anyone tell me the best way to cut a 3 to 4-inch hole in the brick so I can run the duct through it?

    A couple years ago we had an electrician install some boxes and run some wiring and I believe that he took a 1/2" drill bit and drilled holes in a circular pattern through a concrete wall. Then he took a hammer and tapped out the inner circle.

    Can anyone share some experiences or ideas?

    Thanks in anticipation

    just take you time and drill and chisel it out, one hole isn't worth dealing with the rental company and you can pocket the diff.

    Your not going to chisel a circular hole, especially in brick. You'll crack everything and make more problems than it's worth. Go rent a diamond core drill and bit for a hour.

    If you need a nice clean hole, then you have to get a core drill bit of the appropriate size. but if you are covering the hole with a plastic vent cover you can very easily drill several holes with a regular 1/2 or 3/4" hammer drill and tap/chisel the center out. I have done this through concrete block and it worked fine. just be careful and mark the holes correctly.

    Andrew - Go with the core drill. Even though you will be covering the face w/ a plate you still have to slide the duct through the hole and if its not smooth it could be a nightmare.

    As everyone else....core drill. Most any decent electrician or plumber will have the hammer drill and bit and ussually charge $100-150 well worth it not to have the aggravation.

    Thanks everyone. I'll see if I can locate a core drill.
