Doing a garage door installation on your own is not really an option. I discovered that the other day when I tried doing it.
As a guy, I am totally stubborn and refuse to be beaten by anything. Especially Austin garage doors. Saying that, in the end I do reach breaking point and submit to the inevitable.
I had been trying to install it myself for hours, but in the end I had to ask the wife for help. That is a major fail, but it does not happen very often in my life.
