The Houston Plumbing Company That Turned 30% Estimate Conversion Into 54%
A plumbing contractor in Houston was sending quotes and hearing nothing. An AI follow-up system changed what happened after the quote went out — and changed the business.
Most trades businesses live and die by their estimate conversion rate. Send a quote, wait, hope. The ones who follow up consistently win more work. The ones who don't — which is most of them, because following up consistently is tedious and easy to deprioritize — leave revenue on the table constantly.
A plumbing contractor in the Houston area was running a seven-person operation doing roughly $2.4 million in annual revenue. Their estimate conversion rate was 31% — not bad for the industry, but the owner knew from experience that the jobs they lost weren't going to competitors who were cheaper. They were going to competitors who responded faster, followed up, and answered questions before the customer had to ask.
He didn't have the bandwidth to do that manually across 40–60 estimates per month.
The AI follow-up system
An AI automation specialist built a follow-up sequence triggered the moment a quote is sent. The sequence:
- Two hours after the quote: a text message asking if the customer received it and if they have questions.
- Day 2: an email with a brief summary of what the quote includes and why it's priced the way it is (a template the owner wrote once, customized with job-specific details automatically).
- Day 4: a text with a gentle prompt — "We have availability next week if you'd like to get scheduled."
- Day 7: a final message offering a brief call to walk through any questions.
If the customer responds at any point, the automation pauses and the owner or office manager takes over.
For won jobs, a separate sequence handles appointment confirmation, day-before reminders, and post-job review requests.
Build cost: $1,900. Timeline: one week.
The result
Estimate conversion rate went from 31% to 54% within the first 90 days. On a base of 50 estimates per month at an average job value of $1,800, that's 11–12 additional jobs per month. Revenue increased by an estimated $20,000–$22,000 per month.
The owner's comment: "I had no idea how many jobs I was losing just because I didn't follow up."
