It's important to realize that scaffolding can be dangerous. I'd like to relate what happened to me today as an example of the potential hazards.
I had noticed that a woodpecker had made a hole in the cedar shingles above one of the second-story windows. I decided I should put some putty in it to try to keep him from making it bigger. I got out my 24' extension ladder, but it was just a little bit too short to reach the hole so I decided to use my trusty scaffolding. As I was putting it up, Mrs. Quicksand spotted me, and said, "I want to wash the outside of that window while you have that there."
I got the scaffold up and quickly patched the woodpecker hole, but I realized that there were a few spots on the trim over the window that really needed caulking. So I had to go down and find a caulking gun and a tube of caulk that hadn't hardened and took care of that. When I came down a noticed a piece of cedar shingle on the ground, one of the shingles under the window had come loose. So I went and got a hammer and some siding nails to tack it back up. I noticed some of the other shingles on the same row were loose so I put a few nails in them as well.
Mrs. Quicksand then washed the window. She commented that when we had the house painted the painter for some reason had painted the frame of that window the wrong color. She hadn't noticed it right away but it has bothered her ever since. So I went and found a brush and the can of paint in the basement. It turns out I got the wrong color and had to go back and find the right color. Then she commented that where I had caulked the trim you could really see the caulk so I had to get another can of paint to paint over that.
By then it was lunchtime, and half the day was gone! And that's the danger of scaffolding, once you
get up there you find all kinds of things to do.
