Sela did some work for us nearly 20 years ago when we first moved in to Dream Park (replaced garage doors and porch roof). I had exactly the same complaint, even back then. They did the work just fine, but didn't clean ANYTHING up. Left pieces of broken wood and nails all over the place. I thought it was my fault because I hadn't explicitly asked for cleanup in the contract I signed.

From the comments here, it sounds more like a problem with that company in particular.
