I just talked to Tree Company with regards to their cleaning up the site.
They said they couldn't do it now as the ground is still too wet to use machine. Of course the ground can't be clearly dry but obviously they can do their job. All building company are doing their jobs with the machine out there. They just want to do their cleaning job on their convenience.
It happened that we rushed so instead of waiting for a good company, we gave our business for a unreferenced company. Should never do it again!
