Best Proper Tree Trimming Service in Phoenix AZ

I was over charged for the job performed. They only found water staining on the drywall, so drywall needed to be repaired. The workmen did cut several holes and poke holes to make sure there was not any other water that we could not see, so this was good. Containment was done. I am concerned that the containment was not done properly because it has gaps, and does not have the 3 stages built into it. I have a medically fragile child, so containment for even dust is important.
