How plumbers win calls with direct mail
Direct mail works for plumbers when it puts the phone number inside the house before anything breaks. A homeowner standing in an inch of water does not compare five websites. They call the number on the fridge, the card in the kitchen drawer, or the company whose truck was at the neighbor's house last week.
That makes plumbing different from most trades that mail. The goal of the first mailing is not an immediate call. It is to be the card that gets kept, so the call comes weeks or months later when a supply line fails or the water heater stops producing hot water.
The second kind of call is planned work: a water heater replacement, a repipe in an older house, a sewer camera inspection before a home sale. These buyers do compare, and a mailer that shows a license number, a clear price on one service and a local phone number gives them a reason to call you first.
Which printed pieces fit a plumbing business
Three pieces cover almost every plumbing need, each for a different moment.
- 4.25″ × 11″ postcard: the keep-this-card mailer. It is tall and narrow, which suits a fridge or the inside of a cabinet door, and it qualifies for EDDM (Every Door Direct Mail, the USPS service that delivers to every address on a carrier route without a mailing list). Printed on thick 16pt card, it survives months of handling. 5,000 cost $499.
- 4.25″ × 11″ door hanger: for the houses around every job. Neighbors share the same age of pipes, water heaters and sewer lines, so a problem at one house often means the same problem is coming next door. 2,500 cost $409.
- 3.5″ × 2″ business card: two with every invoice, one to keep and one to pass on. 2,500 cost $69.
If your techs still write tickets by hand, 8.5″ × 11″ NCR forms (carbonless copies, so the customer gets a copy and you keep one) start at 500 for $199 for 2-part sets. A smaller 4″ × 6″ postcard costs less, 2,500 for $179, but it cannot go through EDDM, so it only works for addressed mail or hand delivery.
What to print on a plumbing mailer
Put the phone number in type as large as the headline. On a card that will be read in a hurry, the number matters more than the logo.
Give the homeowner a reason to keep it. A short panel on where to find the main water shut-off valve, or what to do in the first ten minutes of a leak, turns an ad into something useful. Useful information gives the reader a reason to keep the card where they will find it.
Add the trust signals plumbing buyers look for: your license number where your state requires one, "licensed and insured", the towns you serve, and a real photo of your truck or your team. Pick one offer, such as a fixed price for a water heater flush or a discount on the first repair, and print it once, clearly. Our guide to headlines and offers that get calls covers the wording.
When plumbers should mail
Emergencies happen all year, so the base of a plumbing plan is steady: the same routes every one to two months, so a fresh card replaces the one that got thrown away. Seasonal messages then sit on top of that rhythm.
- Early fall: water heater flush and inspection, before the heating season adds load.
- Before the first freeze in colder areas: a burst pipe prevention card with outdoor faucet and exposed pipe tips.
- Spring: sump pump checks before heavy rain, and sewer camera inspections for buyers and sellers in a busy housing season.
- After every job: door hangers on the five to ten houses on each side and across the street, the same day if possible.
Older neighborhoods usually need more plumbing work. When you choose carrier routes on the USPS EDDM map, start with older housing close to your shop to keep drive times short.
What a plumbing direct mail starter order costs
A practical first order: 5,000 4.25″ × 11″ postcards ($499), 2,500 4.25″ × 11″ door hangers ($409) and 2,500 business cards ($69). The printing total is $977 before shipping.
That covers one EDDM drop to about 5,000 homes, door hangers for a few hundred jobs, and cards for every invoice for months. If you want us to design the postcard, add $69, and $89 for the door hanger.
Postage is paid to USPS when you drop the mailing off. Put your household count into the EDDM cost calculator to see printing, shipping and postage together, then use the break-even calculator with your own average job profit to see how many calls the mailing needs. Our longer guide, direct mail for plumbers, walks through the full plan.
