Skill Mammoth vs Thumbtack: Renting Contacts or Owning the Phone Call?

TL;DR

Thumbtack is a marketplace. You set a weekly budget, Thumbtack shows your profile to homeowners searching your category, and you are charged when one of them contacts you. There is no monthly platform fee and no lead you buy in advance.

That model is fine for filling a thin week. It is a poor foundation, for one reason that shows up in every pro forum thread: you pay when the customer makes contact, not when the customer turns into work. Around three quarters of those contacts go quiet, and Thumbtack shows the same homeowner four to five pros who can all quote.

Skill Mammoth builds the thing a marketplace rents you: a site you own, rankings in your own name, and follow-up fast enough that the lead is yours before a competitor calls back. Slower to start, and it does not switch off when you stop paying.

Quick verdict by scenario

• Your schedule has holes next week. Thumbtack. Nothing else fills a calendar in 48 hours, and that is a real problem worth solving with rented demand.
• You are testing a new service line or a new metro. Thumbtack. Cheap way to learn whether demand exists before you invest in ranking for it.
• You want to stop paying per conversation. Skill Mammoth. The economics only improve if you own the asset producing the calls.
• Average job under $500. Neither, at least not on paid contacts. The arithmetic below explains why.
• You are already spending $1,500+ a month on marketplaces. Skill Mammoth. At that spend you are funding someone else's brand every month with nothing accumulating.

How Thumbtack actually charges you

This is where Thumbtack differs from Angi Leads, and the difference matters more than most comparisons admit.

There is no fixed monthly fee. You set a weekly budget, and Thumbtack charges you when a customer reaches out. The charge is tied to contact, not to a purchase you approved lead by lead. Pros running automatic leads report being billed whenever a customer makes contact at all, which is inside Thumbtack's stated guidelines but catches people who assumed a charge required a conversation.

Reported costs run roughly $5 to $150 per lead, with most trades landing between $20 and $60. The spread tracks job size and metro. House cleaning sits near the bottom. Roofing and remodeling sit near the top. The same plumbing lead can cost $25 in suburban Ohio and $60 to $80 in Los Angeles or New York.

Typical monthly spend runs from about $300 in small categories to $3,000 and up for high-ticket trades in competitive metros.

Worth looking at what the signup actually promises. "Sign up for free" is accurate, because the account costs nothing. The cost arrives per conversation afterwards, which is the part that decides whether the channel works for you. The volume claim is real too, and volume is not the problem. The problem is that the same volume is shown to four or five of you.

Run the arithmetic before you run the budget

Take a $50 contact charge against a $2,000 average job. Ignore materials and labor for a second and look only at acquisition:

• Close 1 in 10 and you have spent $500 to win $2,000. That is break-even against a healthy marketing budget, not a win.
• Close 1 in 5 and you have spent $250 to win $2,000. That works.
• Close 1 in 20 and the channel is quietly costing you money while looking busy.

Now apply the response rate. If roughly 75% of contacts go silent, your effective close rate against money spent is far worse than your close rate against conversations held. Pros in Thumbtack's own community forum report that unresponsive customers are not covered by the refund policy, so a contact that never replies is generally a contact you paid for.

For jobs under $500 the math tightens to the point where you need to close about one in four to make it work, which almost nobody does on a shared marketplace lead.

This is the same exercise we walk through in how to get contractor leads, where marketplaces rank as a stopgap rather than a foundation.

Where Thumbtack genuinely wins

Two places, and they are real.

Speed. SEO takes months. A Thumbtack budget takes an afternoon. If you have crews idle in nine days, no amount of long-term thinking fills that gap, and choosing the marketplace is the correct business decision.

Market testing. Wondering whether your metro has demand for drain jetting or EV charger installs? Two weeks on a marketplace answers that faster and cheaper than building pages and waiting to rank.

What it does not do is compound. Stop the budget and the calls stop the same day. Nothing you paid for in month one is still working for you in month fourteen.

What Skill Mammoth builds instead

A custom site you own outright, local rankings in your own business name, and the follow-up that decides who wins a shared lead anyway. Every form, chat and missed call gets a text back in under 60 seconds, which is the single mechanic that determines who books the job when a homeowner contacts five pros at once. That system is described in the follow-up system.

Our pricing is published on the pricing page, including what happens if you leave. No custom quote required to find out what something costs.

The honest tradeoff: this is slower. Ranking takes months, and month one produces less than a marketplace budget would. What you get for that patience is an asset that keeps producing after you stop paying, and a phone number that is yours rather than a platform's.

Renting versus owning, over 24 months

Take a contractor spending $1,200 a month on marketplace contacts. Over two years that is $28,800, and on the last day of month 24 they own exactly what they owned on day one, which is nothing. Stop paying and the pipeline stops.

The same budget directed at a site, local search and follow-up produces an asset that still ranks in month 25, reviews that keep accumulating, and a brand homeowners search by name. The true cost of a contractor website covers every build path honestly, including the cheap ones.

Most contractors we work with do not stop marketplaces cold. They run them while the owned channels come up, then taper as organic calls replace paid contacts. That is the sane transition and we say so on the call.

FAQ

Q: Is Thumbtack worth it for contractors in 2026?
A: For filling short-term gaps and testing new services, yes. As your main source of work, rarely. The economics depend entirely on your average job value and close rate. Above roughly $2,000 a job with a 20% close rate it can work. Under $500 a job it almost never does.

Q: How much does a Thumbtack lead cost?
A: Roughly $5 to $150 depending on trade and metro, with most trades between $20 and $60. Cleaning sits at the low end, roofing and remodeling at the high end, and dense metros cost two to three times what suburban markets do.

Q: Do you get charged if the customer never replies?
A: Generally yes. The charge is tied to the customer contacting you, and pros in Thumbtack's community forum consistently report that an unresponsive customer is not grounds for a refund. Build that into your cost per acquired job rather than your cost per lead.

Q: Are Thumbtack leads exclusive?
A: No. Thumbtack typically shows a homeowner four to five matching pros. Speed of response is what separates the pro who books the job from the four who paid for the same conversation.

Q: Should I quit Thumbtack when I start SEO?
A: No. Run both, then taper the marketplace as organic calls come up. Cutting paid demand before owned demand exists is how contractors end up with a quiet month and a grudge against SEO.
