Unlike a filter or a tune-up, nothing in an attic reminds a customer that you exist.
Insulation play · Past customers
Past insulation customers still have the rest of the house to finish.
Insulation doesn't wear out quickly, so most contractors never contact a customer again. But a customer who did the attic often still has rim joists, a crawl space, or a garage ceiling. Spur mails your list about the next area of the house, written around the job you did.

The problem
Insulation customers vanish because the job lasts for decades.
Many customers left rim joists, crawl spaces, and bonus rooms for later, then forgot.
Owners who liked the work can't remember your name when a neighbor asks.

AI draft for Sue K. · 114 Scottholm Blvd
Hi Sue,
We insulated and sealed your attic back in 2019. If that made a difference, thank you for trusting us with it. If you still feel a chill near the floors on cold days, the usual next suspects in a 1934 home are the rim joists and the basement walls.
As a past customer, you can have a free re-check. We'll look at the attic to make sure it's still doing its job, take a look at the rim joists, and give you a straight answer about whether anything else is worth doing.
Scan the code on this card to set a time. And if a neighbor ever asks, we'd be happy to help them too.

How to reactivate customers when the product lasts for decades
Most insulation contractors treat each job as a finished transaction. That makes sense on the surface, because attic insulation can last for decades and customers don't have a reason to call. But a typical job leaves work undone. Budgets are limited, and owners usually start with the attic. That means your old job list is really a list of homes with known, unfinished comfort problems, and owners who already know you do good work.
Write about the next area of the house. If you did the attic, the next logical conversation is usually rim joists, crawl spaces, or floors over a garage. ENERGY STAR's savings estimate includes attics, floors over crawl spaces, and accessible basement rim joists, so it's a natural extension and not an upsell for its own sake. Referencing the year of the job and what you did shows the card came from someone who remembers the house.
Offer a re-check. A free visit to verify that the original job is holding up is low-pressure, gives you a chance to catch problems, and earns goodwill. Things do change: another contractor may have disturbed insulation while working on a bath fan or an electrical run, or an HVAC replacement may have left the hatch unsealed. Finding this for a customer is the opposite of a sales call, and it often leads to one.
Clean the list first. If a home has sold, the customer you knew has moved on, and the new owner doesn't care about your 2019 job. Send a separate note to new owners explaining what's already been done in the attic and offering a copy of the paperwork. Under the FTC's R-Value Rule, you gave the original owner a contract or receipt showing what was installed, and a new owner may appreciate having that record.
Ask for referrals deliberately. A happy customer forgets your name after a few years, but a card on the counter gives them something to hand to a neighbor. Add a short line about referrals, and offer a thank-you if your state's rules allow it. Mail on or near the anniversary of the job, because that's easy to explain and spreads out the work across the year.
Reactivation mail often produces the best cost per job of any list, because the audience already trusts you. It also takes very little to start. A spreadsheet of past jobs is enough, and a few hundred cards a year will tell you quickly how much unfinished work is sitting in your old invoices.

FAQ
Past customer questions
Why mail past customers if insulation lasts for decades?
Because most jobs leave work undone. Rim joists, crawl spaces, and floors over garages are often still open, and your past customers already trust you.
What should I offer?
A free re-check of the original work, plus a look at the next area of the house. It's low pressure, and it often uncovers real problems.
What about homes that have sold?
Send the new owner a different note. Explain what was done in the attic, offer a copy of the paperwork, and offer a check on the rest of the home.
How do I get my list into Spur?
Upload a CSV from your job software or a spreadsheet, including the job date and work completed if you have them.
How often should I mail past customers?
Once a year near the job anniversary is plenty, with a re-check offer every few years.
