exterior cleaning business automation

Every stage of the customer journey, automated and connected in one place.

About the company

Supreme Exterior Clean, a window and exterior cleaning company operating across Northumberland and the surrounding UK region, offering recurring window cleaning and one-off exterior services.

The problem

The business ran on scattered manual processes across WhatsApp, SMS, email, Facebook Messenger, and Google Business Profile, with no consistent way to engage a new lead quickly or manage the customer relationship afterward.

The solution

Agentum built nine connected automation pillars covering the full business, prioritised by commercial impact.

  • Instant multi-channel lead engagement, including an AI receptionist on Facebook Messenger
  • A trust-building sequence for exterior cleaning quotes and an instant quote flow for window cleaning
  • A seven-touch follow-up sequence across multiple channels
  • Post-sale customer journeys, review generation, email nurture, and a referral programme

The impact

Every new lead gets engaged immediately on whichever channel they use to reach out. Quote follow-up now runs across several touchpoints instead of stopping after one attempt, and existing customers are rewarded automatically for referrals.
