Opened up my soffit vents. Workers were very polite and professional, seem to have done a good job. Did a reasonable job of cleaning up after. They picked up and used a leaf blower, but still found some nails laying around and sawdust in the window sills. They were running very far behind schedule (months later than original estimated date completion), possibly due to pandemic. Not a perfect experience, but I'd still use them again and I would recommend them.
