Water management comes first
Freeze–thaw cycles make uncontrolled water especially important to address. Surface slope, downspouts, adjacent grades and where water can safely travel should be part of the layout discussion.
The unseen work supports the visible work
Excavation and compacted base preparation create the foundation for the finished slab or paver system. Ask the contractor to describe this work in the proposal.
Joints and maintenance are part of the system
Joint layout, curing practices, sealers 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.
