Water management comes first
Freeze–thaw cycles make uncontrolled water especially important. Surface slope, downspouts, adjacent grade and where water can safely travel should be part of the layout discussion.
The unseen work supports the slab
Excavation and compacted base preparation support the finished concrete. Ask the contractor to describe this work clearly in the proposal.
Joints and maintenance are part of the system
Joint layout, curing, sealer choices and winter maintenance all affect performance. Get written care instructions that match the finish you selected.
The final recommendation should come from the actual property, written scope and contractor—not a generic article.
