Slow season marketing: how contractors fill the calendar in quiet months

Start eight to ten weeks before your slow stretch, not during it. Sell maintenance visits that land in the quiet months, reach out to the customers you already have, and run one off-season offer that fits your trade, like fall furnace checks, winter roof inspections or January remodel design meetings. Then set aside cash in your busy months so a slow one doesn’t force you into discounting.

Find your real slow months first

Every trade has a rhythm, but your town and your customer mix set the exact dates. A shop that guesses ends up marketing too late.

1. Pull two years of jobs by month. Your job software, QuickBooks or even your calendar will do. Count booked jobs and revenue for each month.
2. Mark the bottom three months. Those are the months to fill. Note whether the dip is in calls, in sold jobs, or in both.
3. Count back your lead time. A furnace tune-up books a week or two out; a kitchen remodel is signed months before the crew shows up. Your marketing has to start that far ahead of the slow month.
4. Write the dates on next year’s calendar. “Mail fall postcards Sept 1” is a plan. “Do some marketing when it slows down” is not.

Industry data shows how sharp the swings are. ServiceTitan’s water heater data shows the timing for plumbers: January installs ran 18% to 24% above average in 2024 and 2025, with a smaller bump in October [1]. POOLCORP, the big pool supply distributor, booked about 61% of its 2025 net sales in the second and third quarters [2]. In the Jobber trends summary for cleaning businesses, 33% of owners said weather and seasonality affect their business [5].

Those are vendor and company figures, not your numbers. Use them to sanity-check your own two-year count.

Pre-sell maintenance plans in the busy season

The best slow-season job is one you sold months ago. A maintenance plan lets you put scheduled visits exactly where your calendar is emptiest.

• Sell it when the customer feels the pain. The homeowner whose AC died in July is the easiest maintenance-plan sale you’ll ever make. So is the family whose drain backed up on Thanksgiving.
• Schedule visits into your troughs. HVAC heating checks in early fall and cooling checks in spring. Gutter cleaning and roof checks in late fall. Pest perimeter treatments before the season starts.
• Book the visit date at sign-up. A plan with no date on it turns into a reminder you forget to send.
• Bill on a schedule. Monthly or annual billing evens out cash flow, which is the whole point.
• Train techs to spot upgrades. A tune-up visit in a slow month is also when a tech can note the 15-year-old furnace or the tired water heater and write it up for the customer.

Pitch at the end of a repair: “Today was a surprise. Our maintenance plan is how most of our customers avoid the next one. It’s two visits a year, we come to you in [spring/fall], and members get [priority scheduling / a discount on repairs]. Want me to put you on the [month] list?”

Pricing, terms and contract details for plans are covered in the sales guide on maintenance agreements.

Work your past-customer list before you buy a single ad

Your old invoices are the cheapest leads you have. These people already trust you, and many of them have a job they’ve been putting off.

1. Export every customer from the last three years with name, phone, email, address, last job and date.
2. Sort them into small groups by what they need next. Furnace serviced two years ago. Water heater past ten years old. Exterior painted seven years ago. Lawn customer who canceled in August.
3. Send a short, specific text or email to one group at a time. A message that names their equipment or last job gets answered. A blast that says “we’re slow, call us” doesn’t.
4. Call the ones who don’t reply if the job would be large. A five-minute call to a past remodeling customer can fill a month.
5. Ask for a referral at the end of every conversation. The referral program guide has the scripts.

Text, equipment age: Hi [name], it’s [company]. We put in your [water heater / AC] back in [year], so it’s getting toward the age where it pays to have it looked at. We have openings in [month] and can check it in under an hour. Want a time?

Text, lapsed recurring customer: Hi [name], this is [company]. We’d love to have you back on the schedule. We’re booking [spring cleanups / biweekly cleanings / quarterly pest service] now and have a few spots on your street. Reply YES and we’ll send dates.

Email, project planning: Subject: Thinking about a project for next year? Hi [name], winter is when we sit down with homeowners to design spring projects, so there’s time for drawings, permits and ordering. If you’ve been thinking about [kitchen / basement / deck], reply and we’ll set up a no-pressure planning meeting.

Only text people who gave you their number for service and haven’t opted out, and honor STOP replies right away.

Off-season offers that fit your trade

A good off-season offer is something the customer needs anyway, timed so you can do it when you’re free. Here’s what tends to work by trade:

How to frame the offer. Give value with a deadline instead of cutting your price. “Book a fall furnace check by October 31 and we’ll replace your filter at no charge” protects your rate. A straight 20% off teaches customers to wait for your slow season.

Getting the offer in front of people

Use the channels that cost least first, then add paid ones if the calendar is still empty.

1. Past customers by text and email, as above.
2. Your Google Business Profile. Post the offer with a photo and an end date, and keep hours current. See the profile guide.
3. Postcards around your past jobs. USPS Every Door Direct Mail Retail postage is $0.26 a piece, sent to whole carrier routes in batches of 200 to 5,000 per ZIP Code per day [6]. Printing is extra. Details are in the postcards guide.
4. A small ad test. A local Facebook or Google campaign aimed at the neighborhoods you already serve. Keep it to a fixed amount for a set number of weeks and compare cost per booked job; the budget guide shows how.
5. Partners. Agents and property managers have winter work too: pre-listing repairs for spring sales, turnovers, and inspection items.

Plan the cash, not just the calendar

Even a well-marketed slow season brings in less. The shops that come through calmly planned for it in July.

• Set a slow-season reserve. Move a fixed share of every peak-month deposit into a separate account. Aim to cover your fixed costs (payroll for core staff, truck payments, insurance, rent) for the length of your trough.
• Collect prepayment for next season. Annual maintenance plans, prepaid pool openings and prepaid lawn programs bring cash in when you need it most.
• Take deposits on spring projects. A remodel or roof signed in January with a deposit funds materials and keeps the customer committed. The deposits guide covers terms.
• Line up credit before you need it. Banks lend more easily to a business that is busy and profitable than to one in a dry month.
• Do the overhead work now. Truck service, training, licensing hours, hiring for spring and updating your website all fit the quiet weeks.

Here’s a simple reserve worksheet. The numbers are an illustrative example for a small HVAC shop, not a benchmark:

Fill in your own numbers. Every maintenance plan or prepaid program you sell shrinks the gap line.

A 10-week countdown to your slow season

1. 10 weeks out: Confirm your slow months from last year’s job counts. Pick one offer and one end date.
2. 8 weeks out: Build past-customer groups. Write the text, email and postcard. Tell every tech to pitch maintenance plans on every call.
3. 6 weeks out: Send the first past-customer messages. Post the offer on your Google profile. Order postcards.
4. 4 weeks out: Mail postcards around recent jobs. Start a small, capped ad test. Call large past customers who didn’t reply.
5. 2 weeks out: Send a reminder to anyone who opened but didn’t book. Check in with partners.
6. During the slow month: Work the plan, track booked jobs by source, and note what to start earlier next year.

This is stage eight of the full contractor marketing guide. The calls it brings in only help if someone picks up. If you’re on a roof or under a sink when they come, the calls-and-leads guide on how fast to call back applies here too.
