Type "free leads for contractors" into Google and you'll get two kinds of results. Companies whose free thing requires a card on file, and blog posts telling you to ask for referrals. Neither is much help at 9pm on a Sunday when next month's schedule has a hole in it.
So here's the useful version. Eight sources that genuinely cost nothing but your time, listed first and in full, because you should be running all of them before you spend a dollar. Then an honest account of what the word "free" means when a lead platform uses it — including ours.
Eight genuinely free sources of contractor leads
Ranked by return on the hours you put in, best first. Most contractors run two or three of these and assume the rest aren't worth it.
1. Your Google Business Profile
The highest-return free thing available to a contractor, and the most commonly half-finished. A complete profile — every service listed, service area set correctly, hours accurate, twenty-plus photos of actual jobs, and a habit of answering every review — puts you in local map results where buyers with immediate intent are looking. Free forever, no catch, and it compounds. Budget six hours to set up properly and twenty minutes a week to maintain. It also feeds every other channel you run, paid ones included — see how the models compare on cost per job won.
2. Referrals, asked for properly
Referrals are the most valuable free leads in construction and the most passively handled. "Let me know if you hear of anyone" produces almost nothing, because it gives the customer a job with no instructions.
What works is specific and immediate. Ask once, at the moment the job is finished and they're happiest — not three months later. Name the work you want: "if any of your neighbors are thinking about their panel this year, I'd appreciate the introduction." A named trade and a named timeframe is something a person can actually act on; "anyone" isn't. Then make it effortless — a text they can forward, with your number in it, beats asking them to remember you.
Two habits multiply it. Follow up with the referrer after you've contacted their friend, because people who see the loop close refer again. And ask trades who finish before you: the framer knows who needs an electrician six weeks before the electrician does.
3. Past customers you haven't called
Related but different, and usually neglected. Open your invoicing software, filter to jobs closed 18 to 36 months ago, and call them. Water heaters, roofs, HVAC systems and kitchens all have replacement cycles, and the person who already paid you once is the cheapest buyer you will ever find. An afternoon on the phone against a list you already own beats a month of cold outreach, and it costs nothing but the hour. That is the benchmark every paid source should be measured against.
4. Public agency bid portals
State, county, school district and municipal procurement sites post upcoming work and let you register for notifications at no charge. If your shop is set up for public work — bonding, prevailing wage, prequalification — this is free, structured, high-value lead flow. If it isn't, registering won't change that, so be honest about which you are before investing the time. Public work also runs on a different timeline — where each commercial source reaches you covers that in detail, and how the five kinds of bidding site differ covers which portals are worth registering with at all.
5. General contractors and complementary trades
An electrician who knows two good plumbers refers work to both. Trade relationships are the most durable free source there is, and they're built by being easy to work with rather than by networking. The fastest version: call three GCs you've subbed for and ask what trades they're currently short on. Sometimes the answer is yours. Knowing which contractor is already on a project makes that call considerably easier.
6. Suppliers and supply houses
Your counter guy knows which contractors are busy, which builders are starting work, and which homeowners came in asking questions they couldn't answer. Supply houses field project questions constantly and have no reason not to point people at a contractor they like. This costs you nothing except being someone they like.
7. Local groups where people ask for recommendations
Neighborhood Facebook groups, Nextdoor, and the town subreddit. Low volume, uneven quality, and it takes discipline not to look like spam — answer questions genuinely, mention what you do once, never pitch. But intent is high, because someone asking "who did your roof" is buying, not browsing.
8. Building department records
Permit records are public, and contractors ask about pulling them directly more often than anything else on this list. Here's what that actually involves before you spend a Saturday on it.
There is no single place they live. Every city and county runs its own building department on its own system, with its own rules about what's searchable, what's downloadable, and what requires a request in writing. Some are modern. Plenty still expect a phone call, a form, or a trip to the counter. What comes back is usually a property address and a permit number — no owner phone, no email, no indication of whether the project is still live. Records also age quickly, and a filing you find three weeks late has already been quoted by someone else.
One jurisdiction, worked consistently, can produce something. Covering the six or eight that make up a real service area means learning six or eight different systems, chasing each on its own schedule, and doing the contact research yourself on every record that looks promising. Most contractors try this once.
Run all eight before you pay for anything. If your Google profile is incomplete and you haven't called an old customer this quarter, a paid lead source is treating a symptom. It'll work — it's just the expensive way to fix something free would have fixed.
The four kinds of "free" in lead software
Once you're into paid tools, "free" gets slippery. It reliably means one of four things, and the difference matters:
The question isn't whether a tool is free. It's what you can see before you pay, and whether a card is required to find out.
What free actually costs you
Free sources cost hours, and contractor hours are not free — they're just unbilled. Worth pricing them once:
| Free source | Setup | Ongoing | Cost at $65/hr |
|---|---|---|---|
| Google Business Profile | 6 hrs | 20 min/wk | $390 once, then $87/mo |
| Past-customer calls | 1 hr | 3 hrs/quarter | $65 + $195/quarter |
| One jurisdiction | 2 hrs | 3 hrs/wk | $130 once, then $780/mo |
| Six jurisdictions | 8 hrs | 14 hrs/wk | $520 once, then $3,640/mo |
| Bid portal registration | 4 hrs | 30 min/wk | $260 once, then $130/mo |
Illustrative. Substitute whatever an hour of your own time is genuinely worth — most contractors underprice it badly. Compare the result against what paid access actually costs rather than against zero.
The pattern is the interesting part. Three of these stay cheap forever, because the ongoing time is small and the return compounds. One does not: chasing building department records across several jurisdictions runs roughly $3,600 a month of somebody's time, and that figure assumes the records come back usable, which frequently they don't. Collecting, verifying and completing those records is the job you're really outsourcing. That's the specific job software is worth paying for — not because the data isn't free, but because assembling it by hand across jurisdictions costs more than buying it assembled.
Which is the honest frame for any paid tool. You're not buying access to something secret. You're buying back hours, and the tool is worth it only when it costs less than the hours it replaces. The same arithmetic applied to lead vendors is in our nine-question provider checklist.
When free leads for contractors stop being enough
Free leads for contractors have a ceiling, and it's usually one of these:
- You've saturated your radius. Everyone within 20 miles who was going to refer you already has. Growth now means a market where nobody knows your name.
- Your flow is seasonal and your payroll isn't. Referrals arrive when they arrive. Crews get paid on Friday regardless. Paid sources exist to smooth that gap, not to replace the free ones.
- You're entering a new county or a new trade. No referral base, no supplier relationships, no review history. This is where paying for reach is most obviously worth it — check coverage in the new county free before you commit to it.
- You're consistently third to the conversation. If the jobs you lose were awarded before you knew they existed, the problem is timing, and no amount of profile optimization fixes timing. Arriving before the bid list is a different problem from arriving with a better price.
None of those mean stop doing the free things. The eight sources above are still the cheapest leads you'll ever get, and a paid source layered on top of a neglected Google profile underperforms every time. If you are weighing vendors, start with the evaluation checklist rather than the pricing page.
Where TigerLeads fits
We're the fourth kind of free, and since this is a post about free leads for contractors, it's worth being precise about what that means.
Free to start, no credit card. No trial clock, nothing to cancel, no card on file. You create an account and look at real project records in your trade and county.
Five fields visible on every record without spending anything — permit type, job cost, project description, county/city, and state. That's enough to know whether a project is your kind of work before you commit to it. The other fifteen fields, including owner and applicant contact details, unlock when you decide the record is worth it.
Credits cost money. That's the honest part. Browsing is free; unlocking is not. Unlock cost is shown before you confirm and is scored on record quality within a published range, so a complete record with verified contact detail costs more than a thin one. You can see what credits cost before you create an account at all.
What you're paying for is the row in the table that doesn't stay cheap. Records exist across 39 states and more than 300 jurisdictions, in as many different systems, arriving in as many different states of completeness. Turning that into something a contractor can actually call — verified, current, with contact detail attached — is the work, and it's the part that doesn't scale by hand. That's what we do.
Which is why the honest comparison isn't against zero. It's against the hours the alternative takes, and whether those hours produce anything you can act on at the end of them.
Look before you spend anything. Create an account with no card, browse real records in your trade and county, and see the unlock cost on each one before you commit. Get started free · See pricing · (888) 888-1214
Frequently asked questions
Are there really free leads for contractors?
Yes, but they cost time instead of money. A complete Google Business Profile, referrals asked for properly, past-customer follow-up, building department records, public bid portals, trade and supplier relationships, and local recommendation groups are all genuinely free. What doesn't exist is a source that costs neither time nor money.
Where can I find free construction leads online?
Building department records publish issued permits at no charge, and public agency procurement sites post upcoming work with free notification signup. Both are genuinely free. The limitation is that each jurisdiction runs its own system, so covering several counties by hand becomes a part-time job. How that data is assembled and verified is the work you would be replacing.
Why do most "free" lead sites ask for a credit card?
Because it's a free trial rather than a free tier — access for a fixed window, then automatic billing. That's legitimate if you'll test it properly inside the window, but check the renewal date and the cancellation terms before entering a card. A genuine free tier doesn't need one — ours doesn't.
Is TigerLeads free?
Free to start with no credit card, and free to browse. Every record shows five fields — permit type, job cost, project description, county/city and state — at no cost. Unlocking the remaining fifteen, including contact details, costs credits, and the cost is shown before you confirm.
Are free contractor leads worth pursuing?
They're the highest-return leads available, which is why they belong first. A complete Google Business Profile and a quarterly pass through past customers will outperform most paid sources per dollar. Paid sources make sense on top of those, not instead of them. Comparing paid models is a second-step question.
How much does it cost to gather permit leads myself?
One jurisdiction runs roughly 3 hours a week — around $780 a month of your own time at $65 an hour. Six run closer to 14 hours a week, and that assumes the records come back complete enough to use, which is the part most people underestimate. That arithmetic, rather than the price of the data, is usually what decides whether software is worth it.
