Looking for any suggestions for the following situation. The house we bought had a kerosene heater in the basement and vented through the base of the house which is vinyl sided. I am removing the heater and all the piping, venting and kerosene line. This is leaving a 3 1/2" hole in the side of the house where the vent piping went through. I looked at possibly using a dryer vent to close up the hole, but they look to be a standard 4" size. I am finding many suggestions on how to patch vinyl siding, but not any that address closing up a hole. I have looked at some vinyl vents, but they are not the correct size. Any ideas, suggestions or feedback would be appreciated.

    Do you have spare siding? What color is it? How is "patching" siding different from "closing up a hole"? A photo would be great.

  • Yep, usually if you want a hole in the siding gone, you replace that piece of siding. Otherwise grab a 4" hole saw and put in a dyer vent, or get one of those vinyl siding bits intended to mount an outside wall light on and cut a hole to fit that over the hole you have.

  • I was getting hung up on the fact that there was a hole all the way through the house to the cellar. But replacing the siding is a great idea. Owner did not leave any scrap pieces and siding is probably almost 30 years old. However, I have a guy coming next week to replace all the windows and he will have to take off the siding and do some patching from the back of the house. I will ask him if he will put a piece in over this. Thank you for the replies.
