If the moisture source wasn't fully fixed, mold comes back. The customer thinks the company failed instead of calling you.
Mold remediation play · Past customer reactivation
Mold remediation past customers, reminded before moisture returns.
Customers who had mold once may see it again if the moisture source isn't solved, and the ones who didn't have it again are your best referrers. Spur takes your customer list, writes a friendly annual check-in, mails it, and flags who scans.

The problem
After the job, most mold companies never speak to the customer again.
Happy customers rarely refer unprompted. A simple, polite ask on a card brings introductions you'd never get otherwise.
Two or three years of past jobs is your cheapest marketing list, and it's unused.

AI draft for Roy C. · 905 S Gaylord St
Hi Roy,
It's been a year since we cleared your basement, and I wanted to check that everything is staying dry.
If you'd like a quick moisture reading, scan the code and I'll send someone, no charge.
And if a friend or neighbor ever has a damp-basement worry, I'd be grateful if you passed my name along.

Why past mold customers are worth a second look
Mold remediation removes the growth, but the cause is moisture, and moisture can return if the source isn't fully corrected. A year later, a quick reading answers the question every past customer silently asks: is it still dry? If the answer is yes, they trust you more. If not, you catch it early, and the second job is smaller.
Anniversary timing feels personal. A card that arrives a year after the job, mentioning what you did, reads as care rather than marketing. It also catches problems before the customer notices them, and a customer who is called early is far more likely to stay loyal than one who discovers the problem alone.
Ask for referrals plainly. Most customers are happy to help but never think of it. A single sentence on the card, asking them to pass your name along to friends or neighbors, produces introductions that cost nothing and close at a high rate, because the recommendation comes from someone the buyer trusts.
Give a reason to scan. A free reading is a real service with real value, and it brings you back into the home. During the visit, a technician can check the source of the original problem, note any new risks, and leave a short written summary. That visit often produces add-on work such as drainage, venting, or dehumidification.
Keep records clean. Include only customers who haven't opted out, honor unsubscribe requests, and keep job dates accurate. A past customer list is a relationship, and mailing someone who asked not to be contacted does more damage than any card can repair.

FAQ
Past customer mold marketing questions
How do I get repeat mold remediation customers?
Mail past customers an annual moisture-check offer on the anniversary of the job, and include a short referral ask.
When should I mail past customers?
Around the 12-month anniversary, then at 24 and 36 months. Spur can schedule each customer individually.
What do I need to upload?
Names, addresses, and job dates are enough. Add the job type to personalize each card.
Is it okay to ask for referrals on the card?
Yes. A single polite sentence is fine and effective. Don't offer large rewards, which may be restricted in some states.
