How far in advance do I need to call before digging in Alabama?
At least 2 working days. Alabama 811 takes locate requests statewide and has underground utilities marked before any excavation. Hitting an unmarked gas or power line can injure the crew and lead to costly repairs.
Do excavation contractors need to be licensed in Alabama?
Yes. Alabama requires a state contractor license (AL BC / BCU4 (Building Construction, incl. excavation & grading)) for this work, regulated by Alabama Licensing Board for General Contractors. Look up the license number before you sign a contract.
How deep do footings need to be in Alabama?
In Alabama, footings typically need to extend below the frost line, which is around 12 inches here. A local contractor will confirm the code requirement for your site.
When is the best time of year to dig in Alabama?
Most of the year works in Alabama. Occasional winter freezes can firm up the top few inches of soil, but the 12-inch frost line clears quickly.
