Your past customers and old estimates are your cheapest waterproofing leads.

Upload your customer and quote list, and Spur writes a warm card for each: a pump check for past installs, a gentle follow-up for estimates that stalled, and a thank-you for referrals. A scan tells you who is ready now.

The warmest leads you have are sitting in your own files.

Installs are never revisited

After a system goes in, there is no reminder to test the pump or battery, so the next contact is a problem.

Estimates go cold

A quote that didn't close in the first month is usually forgotten, even though the owner still has the problem.

Referrals aren't thanked

Customers who sent neighbors rarely hear back, which makes them less likely to do it again.

From list to mailbox in one workflow.

Five steps from a dusty spreadsheet to booked return visits.

AI draft for Tom H. · 8830 W 38th Ave

Hi Tom,

It has been about three years since we put in your drain system and sump pump. Most of our customers never think about it again, which is how it should be, but the pump and the backup battery are worth a quick test every year or two.

We'll come by free, check both, and tell you honestly whether anything needs attention. It takes about 20 minutes.

How to reactivate past waterproofing customers and estimates

Waterproofing is a high-ticket, low-frequency purchase, so repeat business takes planning. A customer who had a system installed three years ago is not shopping, but they are the most likely person to refer a neighbor, buy a battery backup, or call again if something changes. Staying in touch with them costs very little compared to finding a new customer.

Start with the installed base. A system with a sump pump and battery has parts that wear, and a yearly or every-other-year check is a reasonable, honest reason to reach out. Offer the check free or at a low flat price, and use the visit to test the pump, inspect the discharge line, and note anything that has changed around the house. Many companies turn this into an annual service plan that pays for itself.

Next, work the estimate backlog. Most estimates that don't close in the first month are not lost; they are paused. The owner may have been waiting on a budget, a second opinion, or a bad week. A refreshed quote after six months or after the next big storm is a natural reason to re-engage. Keep the tone gentle: acknowledge the quote, mention that you can update it, and offer a quick visit.

Don't forget referrers. A thank-you card with a small gift or credit costs little and tells the customer you noticed. People who feel appreciated are much more likely to send the next neighbor, and a referred lead typically closes at a higher rate than any mailed one.

Automate the schedule. Install anniversaries, estimate ages, and referral dates all produce natural triggers. Set them once in Spur, and every cohort is mailed at the right time without a spreadsheet or a reminder.

Keep the data clean. Record the job type, the install date, and the equipment installed, and add notes about anything the owner mentioned, such as plans to finish the basement or a neighbor who might need help. Those details let you write a card that sounds like it came from a person who remembers the house, which is the main reason owners respond to a company they hired years ago.

Past customer and estimate questions

How do I upload my customers and estimates?

Upload a CSV export from your CRM or a spreadsheet with name, address, job type, and date. Spur matches the addresses and builds the lists.

How old should an estimate be before I follow up?

Six months is a good starting point, and after the next big storm is another natural moment. Keep the tone gentle and offer to update the quote.

Should I charge for the check-up?

That is your choice. Many companies offer it free for a first visit and charge a small flat fee afterward, or fold it into a service plan.

Can Spur remind customers every year?

Yes. Set a campaign by install anniversary, and Spur mails each customer at the right time every year.
