Key Takeaways for General Contracting

  • Two-sided rewards (referrer and friend both get a discount or credit) outperform one-sided by 60-80%.
  • For general contracting, calibrate the reward to 5-10% of $42000 average job value.
  • Ask three times: with the review request, 30 days later, and at the natural recurrence cycle for the trade.
  • FTC requires disclosure of the incentive. Build it into the request copy automatically.

Why this matters for General Contracting businesses

For general contracting contractors, referrals are the cheapest and highest-converting channel that exists. A referred general contracting customer closes at 2-3x cold-lead rates and has 25% higher LTV. Average general contracting ticket of $42000 means a $50-$100 referral reward returns dozens of dollars in margin.

The General Contracting-specific angle

Time the referral ask three times. First, right after the customer leaves a positive review post-bathroom remodel — the peak satisfaction moment. Second, 30 days later when they've lived with the result and may have already mentioned you organically. Third, at the natural recurrence cycle: project bidding and planning season for general contracting. Reward structure: two-sided at 5-10% of $42000 average ticket. Both the existing customer and the referred friend get the same credit. Two-sided outperforms one-sided by 60-80% on participation.

Referred general contracting customers cost a fraction of a Google Ads click, close at 2-3x the rate, and have higher LTV. The only question is whether you systematically ask, or rely on luck.

How Cornerstone GC would set this up

Consider Cornerstone GC, a general contracting operation serving Denver, CO. A typical bathroom remodel job at the 1428 Cherry Lane address triggers the following automation:

  1. Technician taps "Job Complete" in the field — bathroom remodel marked done.
  2. 4 hours later, Robert receives an SMS asking for a Google review.
  3. Review request mentions punch-list completion specifically — feeds Local Pack keyword relevance.
  4. If Robert leaves a 4+ star review, a 25-card postcard campaign fires to neighbors around 1428 Cherry Lane.
  5. Robert also gets a referral link — both they and a referred neighbor get a discount on the next job.
  6. Compliance: 9 AM-8 PM quiet hours respected, opt-out logged, license # auto-included on postcards where required.
