Why this matters for Plumbing businesses
For plumbing contractors, reviews aren't just social proof — they're the single biggest input to Local Pack ranking. A plumbing business with 87 reviews collecting 6 new ones per month outranks a competitor with 240 stale reviews. And because plumbing customers tend to search at moments of need — think pre-summer water heater inspections or an urgent drain cleaning call — showing up in the top three at the moment of search converts disproportionately well.
The Plumbing-specific angle
The Plumbing-specific timing rule: send the SMS review request 4-24 hours after the water heater install is complete. For emergency repairs (a midnight call, an after-hours service), ask same-day — the customer's relief is at its peak. For larger projects (whole-home repipe, multi-day installs), wait until the customer has spent 24-48 hours experiencing the finished work. The seasonal cadence matters too: pre-summer water heater inspections is when review velocity matters most for plumbing — that's when Google's Local Pack surfaces you to the maximum number of in-market searchers.
The plumbing business with 5+ new reviews this month outranks the one with 240 reviews and nothing new in 18 months — every time.
How Heritage Plumbing would set this up
Consider Heritage Plumbing, a plumbing operation serving Phoenix, AZ. A typical water heater install job at the 215 Magnolia Way address triggers the following automation:
- Technician taps "Job Complete" in the field — water heater install marked done.
- 4 hours later, Mike receives an SMS asking for a Google review.
- Review request mentions drain cleaning specifically — feeds Local Pack keyword relevance.
- If Mike leaves a 4+ star review, a 25-card postcard campaign fires to neighbors around 215 Magnolia Way.
- Mike also gets a referral link — both they and a referred neighbor get a discount on the next job.
- Compliance: 9 AM-8 PM quiet hours respected, opt-out logged, license # auto-included on postcards where required.
