Plumbers: You’re Paying for Leads You Should Be Getting for FREE.
Most plumbing businesses are addicted to paid leads.

They pay marketing agencies a fortune—without seeing real ROI.

How? They have a referral system that brings in new customers automatically.

The “Hope & Pray” Referral Problem
Most plumbing businesses get referrals by accident.
❌ They do a great job and hope customers will spread the word.
❌ They assume people will “naturally” tell their friends.
❌ They wait for word-of-mouth to happen on its own.
That’s NOT a system—that’s gambling.
Referrals don’t just happen. They have to be engineered.
Step 1: Make Referrals a Condition of Doing Business
🔥 Customers will refer you—if you make it part of your process.
At the end of every job, say this: "We love working with great customers like you. If you know anyone who needs plumbing work, we’d love to take care of them. Who do you know that could use our help?"
Why it works: Most customers don’t think about referring you until you ask. The best time to ask? When they’re thrilled with your work.
Bonus: Give your techs a $25 bonus every time they get a referral on-site. They’ll start asking—guaranteed.
Step 2: Create a Referral Reward That Excites Customers
❌ Most plumbing referral programs are boring.
❌ “Get $10 off your next service” is NOT a reason for customers to care.
❌ Nobody is referring you just to save a few bucks.
Fix this with an irresistible referral offer:
💰 $50 Cash or Gift Card – Instant reward when their referral books a job.
🔥 1 Free Drain Cleaning – If their referral becomes a customer.
🏆 Quarterly Giveaway – “Refer someone and get entered to win a free water heater install!”
Why it works:
✅ Cash is easy & exciting.
✅ A free service feels like a BIG win.
✅ A contest makes referrals FUN and competitive.
People love sending referrals—when they feel rewarded for it.
Step 3: Automate Follow-Ups So Referrals Don’t Get Lost
Most plumbing businesses lose referrals because they don’t follow up the right way.
If you don’t stay on top of referrals, they disappear.
Fix this with targeted follow-ups that add value:
✅ Text every referral immediately: "Hey [Referral Name], [Customer Name] sent you our way, which entitles you to a FREE water heater inspection and flush! Let’s schedule a quick call?"
✅ Follow up 3 days later (if no response): "Hey [Referral Name], just checking in! Your free water heater inspection & flush is still available—want to grab a time this week?"
✅ Email the original customer (to reinforce the referral): "Hey [Customer Name], thanks again for referring [Referral Name]! We reached out and offered them a free water heater inspection and flush. If they book, your reward is on the way!"
This version makes the follow-ups feel exclusive and valuable—without sounding desperate.
Bottom Line: Stop Paying for Leads You Could Be Getting for Free
Referrals don’t happen by accident—they happen by design.
Ask for referrals at the right time (every single job).
Offer an exciting reward (NOT just a small discount).
Follow up so referrals don’t slip through the cracks.
Do this right, and 30-40% of your customers will come from referrals—without spending a dollar on marketing.
🔥 Most plumbing business owners work TOO hard because they’re involved in everything.
