Why referrals are worth the effort
When a neighbor says "use this guy," the homeowner already trusts you before the first phone call. They compare fewer options and often ask fewer questions about price.
Repeat customers are even better. They already know your work, and a roof, a fence, a repaint or a panel upgrade often leads to another job a few years or even a few months later. The challenge isn't earning that trust. It is staying visible so they think of you first.
Step 1: Keep a customer list
You can't follow up with people you can't find. Start a simple list with:
- Name, phone and email
- Address or neighborhood
- What you did and when
- Anything you promised to follow up on, such as a warranty check
A spreadsheet works. So does your phone's contacts app, as long as you keep it in one place. Add every customer when the job closes.
Step 2: Ask at the right moment
The best moment to ask for a referral is right after the final walkthrough, when the customer is happy and the work is fresh. Say it plainly:
"If you know anyone else who needs [roofing, painting, plumbing], I'd appreciate you passing my name along. I'll take good care of them."
A few tips:
- Be specific. "Anyone on your street thinking about a new roof?" is easier to answer than "know anyone?"
- Give them something to share. A business card, a text with your website link, or a magnet makes it simple to hand off your contact details.
- Say thank you. A short call, text or handwritten note after a referral turns one favor into a habit.
Step 3: Thank referrers the right way
A thank-you matters. A small gift of appreciation after a referral turns into a job is fine in many cases, but check the rules that apply to you. Don't make the thank-you conditional on a review, and never tie it to how a customer rates you online. Paying or rewarding people for reviews is prohibited, and that is separate from thanking someone for a personal introduction.
This is general information, not legal advice.
Step 4: Stay in touch without being annoying
Most contractors disappear after the final invoice. Then the customer forgets them and calls someone new when the next job comes up.
Reach out a few times a year, and each time give them a reason that is useful to them:
- A check-in after the job. A week or two later, ask whether everything is working as expected.
- Seasonal reminders. Gutter cleaning before the rainy season, an HVAC tune-up before summer, a roof inspection before winter. See our seasonal marketing calendar for ideas.
- Anniversary notes. "It has been a year since we did your deck. Happy to take a look if you want a check."
- A thank-you at the holidays. Short, warm and without a pitch.
If you send texts, follow the consent rules. We cover them in texting customers legally.
Step 5: Ask for the review too
A referral and a review are two different asks, but both come from the same happy customer. After the job, ask for a Google review and mention that you would appreciate a referral if they know someone. Our guide on Google reviews for contractors explains how to ask in a way that follows Google's rules.
Step 6: Make yourself easy to recommend
People pass along contractors who are easy to explain. Check that a stranger could understand, in one sentence, what you do and where:
- A clear website with your trade, your service area and your CSLB license number. See what a contractor website needs.
- A phone number that gets answered, or a quick call back.
- A fast, polite reply to anyone who reaches out because a friend sent them.
Nothing wastes a referral faster than a slow response. The person who got your name is warm for a day or two.
Track what works
Ask every new customer, "How did you hear about us?" Write the answer next to their name. After a few months you will see which sources bring in jobs, and which past customers are your best advocates.

Questions people ask
How soon should I ask for a referral?
Right after the job is finished and the customer is happy. Ask in person first, and follow up with a short message so they have your details.
Should I pay for referrals?
A small thank-you after a referral turns into work is common. Keep it separate from reviews, never offer anything for a review, and check the rules for your situation.
How often should I contact past customers?
A few times a year is enough for most trades. Each message should give them something useful, not just a sales pitch.
What if I do not have many past customers yet?
Start the list today with every job you can remember, and add each new one as it closes. Even a short list is worth a friendly check-in.
