Why Plumbing Maintenance Plans Are Underused
Most independent plumbing companies have thought about offering a maintenance plan. Few have actually built one. The reasons are usually the same: uncertainty about what to include, uncertainty about how to price it, and uncertainty about whether customers will actually buy it.
The answer to all three: an annual plumbing inspection plus priority scheduling plus 10% off repairs, priced at $149-$349 depending on market, converts at 15-25% when offered at the end of a service call by a technician the customer just watched solve their problem.
What to Include in Your Maintenance Plan
Inclusion
Why It Matters
Annual plumbing inspection
Core deliverable, identifies issues before they become emergencies
Priority scheduling
Highest-value benefit for most customers, especially during peak emergency periods
10% off future repairs
Financial incentive to call you instead of getting a second quote
Water heater check
High-margin add-on that protects against a major homeowner expense
Pricing Your Maintenance Plan
Price your maintenance plan so that the value of the included services is demonstrably greater than the plan price. An annual inspection at your normal service call fee plus a plumbing check is $[your service call fee + inspection rate]. Your plan at $199 is a clear saving for the customer who would pay that rate individually.
The Enrollment Script
After Repair, Before Packing Up
"While I'm here, we have an annual maintenance plan for $[PRICE] that covers a plumbing inspection, priority scheduling, and 10% off any future repairs. Most of our customers say the priority scheduling alone is worth it when something comes up unexpectedly. Want to add that today?"
The Revenue Math
20 new maintenance plan customers per quarter at $199/year = $3,980 in new annual recurring revenue per quarter. 80 new customers per year = $15,920 in predictable annual revenue that does not depend on emergency call volume.
