Should there be gaps between pavers installed by a landscape contractor?

Yes. Uniform joints—often 1/8 to 1/4 inch—are intentional so joint sand or polymeric sand can lock pavers, allow minor movement, and drain surface water. Proper edge restraints and a compacted base keep joints consistent and prevent spread. After installation, sand should be vibrated in and topped off after initial settling. If you see joints that are wide and irregular, sand washing out, or edges creeping, ask for correction: check base thickness, plate compaction, edge restraints, and polymeric sand activation. Well-detailed joints look crisp, shed water, and keep ants and weeds at bay when maintained with periodic sweeping and spot refills.
