Leaks can be very damaging. For one, they can change what one is entitled to in a will. And that, as anyone who’s ever been at the receiving end of one will vouch for, can be quite a life-and-death experience.

For those of you already, so soon into this piece, wondering what I’m on about, please find yourselves a way to watch the commercial for M-Seal in which an unscrupulous son forces his dying father to add a ‘zero’ to the amount bequeathed to him and then ends up with only ‘zeroes’ because a drop of water from a leak in the roof drips itself on to the will and erases the ‘1’ before all the ‘zeroes’ he has just forced his dying father to will him. Don’t ask. Just try to lay your hands on the commercial. As always, youtube might be a good place to start.
