Advice on killing a vine next to a Victorian house.?

I have quite a serious vine growing up against the back of a Victorian house. The ground under the old encaustic tiles is sinking towards the vine so I guess I need to take it out. I've read the advice on how to kill the vine, but I have a couple of other questions:


1. Is there a best time of year to kill it?


2. It's right next to the house. One of the answers I read suggests that if you kill it and the roots are under the house, they'll rot, leave a gap and cause worse subsidence.The house is on a hill and the tiling on a verandah with a 3 - 4 foot drop to "ground level". So I'm figurting that the foundations would be pretty deep and so I'm probably safe unless the roots have eaten in to them. So is it best to cut it. leave it or get in a structural engineer?

Reply:cut it off at the base, and go to your local garden center and get Brush and Stump Killer. Swab it on the cut surface, straight, right out of the bottle, or paint it on, or pour it on (you don't need much) if there is nothing else growing there that you do not want to kill. It will die and never come back. Kill it any time of the year.


It depends on the size of the vine whether or not a void from the rotting roots will cause damage. My guess that leaving it to grow will cause more damage than getting rid of it.
