Septic work has a calendar, and it is not the one most marketing advice assumes. The phone rings when the ground thaws and the water table rises, when houses change hands, and when twelve relatives flush the same toilet over a long weekend. It goes quiet when the ground freezes, in the hottest weeks of summer in the South, and in the stretch between New Year's and the first thaw.
A company that markets the same way all year spends too much in the busy months and too little in the slow ones. Here is the calendar and what to do in each part of it.
The septic year, by region
Northern states (New England, Great Lakes, Upper Midwest, Pacific Northwest):
- January to February: slowest. Frozen ground, frozen lids, few installs. Emergency pumping only.
- March to May: thaw and wet season. Backups, saturated drain fields, the first inspections. Busiest stretch for pumping and repair.
- June to September: install season. Permits, excavation, new construction. Real estate inspections peak.
- October to November: pre-winter pumping rush, then the Thanksgiving spike.
- December: holiday emergencies and little else.
Southern and Sun Belt states (Texas, Florida, Georgia, the Carolinas):
- Hot summer slows pumping in some areas as homeowners put it off; install season runs most of the year.
- Hurricane and heavy rain seasons produce saturated field calls.
- Thanksgiving and Christmas spikes are the same everywhere.
- January to February are quieter but not frozen; a good time to push inspections and risers.
Check your own invoices by month for two years. The pattern will be obvious, and it is what the rest of this plan is built on.
The rule: market for the next season, not this one
Pumping reminders go out six weeks before the busy season, not during it. Install consult offers run in late winter so the permit is in before the ground is workable. Agent outreach happens in February, before spring listings. Marketing during the peak is for filling gaps; marketing before the peak is what makes the peak.
January and February: fill the route from the customer list
This is the month to call your own customers. Every tank you pumped three or four years ago is due. Pull the list, sort by last service date, and send a text:
"Hi [Name], Dale's Septic here. It's been about 3 years since we pumped your tank on [Road]. We'll be in [town] the week of Feb 10, $350 if you book that week. Reply YES and I'll confirm a day."
A customer list of 800 tanks at a 3.5-year cycle means roughly 20 are due every month. A text campaign to past customers typically books 8% to 15%, which is 15 to 30 pump-outs from one afternoon of work, at no ad cost. The email and SMS service does exactly this.
Also in these months: riser installs. "Never pay a dig fee again, $400 installed" is the offer, and winter is when homeowners regret the dig fee most.
February: real estate agents and home inspectors
Spring listings start in March. In February, visit or call every agent and home inspector in your counties. Bring a one-page sheet: inspection price, what the report covers, turnaround, your license, your phone. Offer to do a short talk at their office meeting on what a septic inspection involves. Ten agents who think of you first are worth more than most ad budgets, because every house on septic in their listings needs an inspection and many need a pump-out to pass.
Follow up each spring and fall with a short text: "Inspection season, same price, same-day reports. Here if you need us."
March to May: answer the phone and ask for reviews
The thaw brings backups and the agents bring inspections. Marketing in this stretch is mostly about not losing what comes in: missed-call text-back on, hours set correctly on the profile, pumping ads running at the hours someone answers. The missed calls guide covers it.
This is also the season to bank reviews. Every job is a face-to-face with a relieved customer. One review per three jobs through the spring puts a one-truck company past the 75th percentile, which sits at 38 reviews. The reviews you collect now are what rank you next winter.
June to September: sell installs and risers
Pumping is steady, installs are the money. Run the install consult offer on Google and Meta, put the drain field page and the tiered quote on the site, and post one install job a week on the profile and Facebook with before and after photos. Builders and excavators are worth a call in June; they have lots to develop and need a licensed installer they can rely on.
Every pump-out in summer is a riser pitch. The lid is exposed, the dig fee is fresh, and "$400 and you never pay the dig fee again" closes often.
October and November: the pre-winter push and Thanksgiving
Send the "pump before the ground freezes" text in early October. Run a small Google campaign on "septic pumping before winter." Then, the week before Thanksgiving, post on the profile and Facebook: "Full house this weekend? If it has been more than three years, pump before Thursday. We're open Friday and Saturday." Only 28% of septic companies show Saturday hours, so saying you are open that weekend is a real edge.
Set the profile hours to match the holiday schedule and put the emergency surcharge on the site so nobody is surprised.
What to spend by season
A rough split for a company spending $18,000 a year on marketing: 15% in January and February (texts, risers, agent outreach), 30% in March to May (ads, review tools, text-back), 35% in June to September (install ads, site, Meta), 20% in October to December (pre-winter texts, holiday posts, a small pumping campaign). The slow months are cheap because the work is outreach, not ads, and it is the outreach that fills spring.
Frequently asked
Should I pause Google Ads in January? Lower it, do not pause it. Competitors pause, clicks get cheaper, and the account loses history if it sits off for two months. $300 a month on exact-match pumping terms keeps the route alive.
What about portable toilets or grease traps in the slow season? If you have the equipment, winter is when restaurant grease trap contracts get signed and event rentals get planned. Both are steady work that does not care about the thaw. Add them to the services list on the profile.
How do I know which months are slow for my company? Pull two years of invoices into a spreadsheet by month. Most owners are surprised by how predictable it is, and it tells you exactly when to send the reminder texts.
The seasonal texts to past customers, the agent sheet and the pre-winter campaign are all things that can be set up and run for two weeks on the free 14-day trial.
