Ivy can be very destructive and I'm amazed at the tenacity of those little glue pads. I've talked to a lot of people and looked for a good way to remove them from various surfaces with no luck. The worst is vinyl siding. Has the DOD looked into this adhesive? (no, a wire brush is NOT a good way to go!)
Other than some minor electrical work, replacing a sagging beam and installing a post in the basement, the sale of the old house is a done deal. I had it on the market for a grand total of 12 days before a young couple with kids made an offer and they accepted my counter in a few hours. The house will suite them very well and they can just move in, everything is fresh. But, those ivy feet look terrible on the front porch.
