The office-building exterior cleaning playbook by class
Class A, B, and C office buildings each have distinctly different exterior-cleaning requirements, and a generic cleaning approach fails one of them. Class A — curtain wall, premium finishes, anchor tenants paying premium-per-square-foot rent. The expectation is invisible service. Weekend scheduling, single named account manager, COI naming building ownership and management entity as additional insured, photo documentation that lands in the tenant-portal CMS the same day. Class B — mid-tier corporate offices, sometimes multi-tenant, often mixed-use ground floor. The expectation is reliable scheduling, quarterly recurring contracts, multi-property invoicing if the property manager runs a portfolio. Class C — older buildings, often historic conversions, sometimes still pre-leasing space. The expectation is honest scoping and pricing — many Class C buildings have masonry needs that require the same historic-preservation chemistry we use for churches. Our office program tiers all three classes appropriately. Same crew, same trucks, different scope, different cadence, different SLA. Every building gets a documented service-level expectation in the master service agreement so there is no ambiguity at month 6 about what was promised at month 0.
