Vendor Selection

Transitioning Exterior Services Vendors Without a Service Gap

Part of the guide Vendor Selection, Compliance, and Procurement

The short answer

Onboard the new vendor before the old contract ends, walk and document every building together, hand over access and anchor records, and schedule the first visits before the outgoing vendor's last one.

Seven steps

  1. Check exit terms: notice period, end date and any obligations.
  2. Onboard first: insurance, safety documents and procurement platform. See vendor onboarding.
  3. Walk every building with the new vendor and document existing conditions. See how to document existing facade damage.
  4. Hand over the building file: roof access, anchor certification records, keys, contacts and tenant rules.
  5. Schedule first visits before the last outgoing visit, starting with entrances and the most visible glass.
  6. Tell tenants who the new vendor is and when work starts.
  7. Review after the first cycle and adjust scope and cadence.

Timing

Avoid switching right before peak season for high-rise work, when dates are hardest to get. If you must, lock the new vendor's summer dates first. See weather, seasonality and scheduling risk.

Switching to S&K

S&K walks every property, scopes the work, delivers a clear, fixed proposal and coordinates multi-site starts through one point of contact.
