"Carl, I’m getting bids from the excavator and the concrete company.
They are both asking if I want them to do the footings.
Who do you suggest do the work?
Unless the excavation contractor has a division that specializes in footings, I wouldn't even talk to them about doing my footings.
The concrete footings are one of the most important components in construction.
Use the best (professional) contractor for any job. In this case, use a concrete foundation contractor.
Read my article on House Footings.
