Case Study 02 — Devon & East Cornwall

Leads coming in but
slipping through the cracks.

ADS Windows & Doors were spending on ads but couldn't track results. Good leads went cold. Six months after engaging us, they had two consecutive record-breaking sales months — and 50%+ more appointments booked outside business hours.

Leads Lost to No Follow-Up

The challenge: spending on ads with no system behind them.

ADS Windows & Doors had the right instinct — they were investing in paid advertising — but the infrastructure behind the ads wasn't working. Leads came in and there was no reliable process to respond quickly, follow up consistently, or track what was happening.

Good enquiries were going cold because no one was following up fast enough. There was no CRM visibility. The team didn't know which campaigns were producing revenue and which were wasting budget. The result: inconsistent sales, unpredictable months, and a nagging sense that money was being left on the table.

What we built.

  • An AI booking assistant that responded to every new lead instantly, 24/7 — qualifying them and booking survey appointments automatically
  • A full CRM rebuild, with pipeline stages mapped to their actual sales process and full revenue attribution
  • Multi-step follow-up sequences via SMS and email, triggered automatically based on lead status
  • Rebuilt Google and Meta campaigns, now properly connected to conversion tracking and CRM data
  • Monthly reporting showing exactly which campaigns were generating jobs — not just leads

The result.

Within six months, ADS Windows & Doors had their two best sales months in the business's history — back to back. The system was responding to every lead instantly, following up automatically, and giving the team full visibility of their pipeline for the first time.

50%+ more appointments booked outside business hours. Not from spending more — from making the spend they were already doing actually work.

"Working with Window Growth has seen our leads and sales grow, whilst improving our customer service and internal processes."
— Matt Colton, ADS Windows & Doors
