My Charles and I did the demo work, as you can see in the slide show below. It was a pretty easy demo job. It took about two hours. The only issue was the scorpion (!) that we encountered when digging out the last of the ties and first of the wooden steps.
All in all, I'm ecstatic. The new stairs are pretty, more functional, safer, will be easier to climb in the snow, and I love the gray. When we paint the house gray this next year, it will tie in beautifully. Yay concrete stairs! .
