Parking lot maintenance contractors keep existing pavement in serviceable condition rather than building new pavement. The work is recurring by design: inspection on a set frequency, preventive treatments scheduled before problems become structural, and localized repairs between larger scopes. Depending on the contractor, that can include sweeping, crack sealing, sealcoating, striping and marking refresh, patching, and drainage upkeep.
Some companies are maintenance specialists and subcontract or refer out anything larger. Others are full-service paving contractors with a maintenance division, which means the same firm can escalate from routine upkeep to repair or replacement. Neither is inherently better, but it changes who you are dealing with when the pavement needs more than maintenance — worth knowing before you sign a multi-year agreement.
