How Glazing Companies Use WhatsApp & SMS to Book More Appointments

The Communication Shift

Homeowners under 50 increasingly prefer text-based communication over phone calls. A CRM-triggered SMS gets read within 3 minutes. A phone call from an unknown number? Ignored 60% of the time.

Where SMS/WhatsApp Works Best

Appointment Confirmations

"Hi [name], confirming your appointment with [rep name] on [date] at [time]. Reply YES to confirm or call us on [number] to rearrange."

Result: 25-30% reduction in no-shows.

Post-Quote Follow-Up

"Hi [name], just checking you received the quotation we sent on [date]. Happy to answer any questions — just reply to this message."

Result: Higher response rate than phone calls for quote follow-up.

Day-Before Reminders

"Reminder: [rep name] will be visiting tomorrow at [time] for your window survey. Please ensure access to all rooms with windows to be replaced."

Result: Better-prepared customers, more productive appointments.

Installation Updates

"Your new windows are scheduled for installation on [date]. Our fitting team will arrive between 8-9am. Any questions, reply here."

Result: Fewer installation-day surprises and cancellations.

Compliance Considerations

  • Always get consent before sending marketing messages
  • Appointment confirmations and updates are generally fine as "service messages"
  • Include an opt-out option in marketing texts
  • Keep records of consent in your CRM
  • Don't send texts outside reasonable hours (9am-7pm)

Tracking in Your CRM

Log all SMS and WhatsApp communications against the lead record:

  • Which messages were sent and when
  • Customer responses
  • Open and reply rates by message type
  • Conversion impact (do customers who receive texts book more appointments?)
