Cheap Leads for Builders: What They Really Cost Per Signed Job

Cheap leads for builders can cost about $6,000 per signed job once you count who never answers, who never books a site visit and how many quotes you lose: in the worked model below, a $40 shared lead costs nearly twice as much per signed contract as a $91 search-ad lead, because you need about 42 of them to win one job.

Rules of thumb (each one sourced or taken from the worked table below):

• Cost per signed job = cost per lead ÷ (contact rate × site-visit rate × quote rate × win rate). At 50%, 40%, 80% and 15%, that divisor is 0.024, so one signed job needs about 42 leads.
• A lead at half the price is only cheaper if it converts at more than half the rate. The $40 shared lead in the table converts to a signed job at 2.4%, against 8.9% for the $91 search-ad lead.
• Your own time is the biggest cost, not the lead. In the table, site visits and quoting are 68% to 91% of the cost per signed job.
• A shared lead caps your odds before quality even matters. hipages caps each lead at 3 businesses and Angi matches each request with no more than five pros.

What do cheap builder leads really cost per signed job?

Cheap builder leads cost $2,000 to $6,000 per signed job in the worked model below, and the cheapest source per lead comes out the most expensive per contract. The model counts the leads, visits and quotes behind one signed job, plus your time at 2 hours per visit, 4 per quote and $100 an hour.

The worked model shows the trap plainly: the shared lead is 56% cheaper than the search-ad lead per lead, but it needs 3.7 times as many leads and more than twice as many unpaid site visits to win one job. Only the search-ad cost per lead comes from a published benchmark (LocaliQ does not state the countries in its data); Australian builders should use their own account figure. Swap in your own numbers and the ranking can change.

What do builder lead marketplaces publish about their prices?

Builder lead marketplaces in Australia and the US mostly publish how leads are priced, not a fixed price per lead, so your real cost per lead only shows up in your own account. Each platform’s own page, read 27 October 2026:

Why do shared leads cost builders more per signed contract?

Shared leads cost builders more per signed contract because the same homeowner goes to up to 3 (hipages) or 5 (Angi) businesses, which caps your win rate from the start.

• The first caller wins the conversation. With three to five builders ringing, the fastest often gets the site visit. See the speed-to-lead playbook for trade businesses.
• Price shoppers self-select. A homeowner collecting several quotes often compares on price.
• Unpaid site visits pile up. At a 15% win rate the model needs 8.3 site visits per signed job, which is where 43 hours of the builder’s time go.

Marketplaces still suit small jobs with short visits and template quotes. The trap is extensions, renovations and new homes, where every lost quote can cost a day of estimating.

How do you calculate your own cost per signed job?

You calculate cost per signed job by tagging every enquiry with its source, then counting it through four stages: contacted, site visit booked, quote sent and contract signed. Call it the Signed-Job Ladder:

1. Tag the source on every lead (marketplace, Google Ads, Local Services Ads, referral, website form, old quote) in your CRM. The guide to tracking which leads become booked jobs shows how.
2. Count the four stages per source over the last 3 to 6 months, pooling months until each source has a few signed jobs.
3. Add your time. Hours per site visit and per quote, at what your time is honestly worth. Skip this row and the source with the cheapest leads will look best by default.
4. Divide total spend plus time by signed jobs. Move budget toward the lowest source, and fix the stage with the biggest drop before buying more leads.

Where the biggest drop is contact rate, the fix is follow-up, not a new lead source. Where it is quote-to-signed, qualify on the first call: see the land, finance, budget and timeline gates for custom home enquiries.

When is a cheap lead source worth it for a builder?

A cheap lead source is worth it for a builder when its cost per signed job, time included, beats your other sources, which often means small jobs, fast follow-up and short quotes.

Old quotes are the cheapest lead a builder owns ($2,036 per signed job in the model). The database reactivation guide covers working quoted-but-never-signed jobs.

How does this differ between Australian and US builders?

Australian and US builders face the same cost-per-signed-job maths, but different marketplaces and rules on contacting leads. In Australia, marketing texts fall under the Spam Act 2003 (ACMA) and telemarketing calls under the Do Not Call Register rules. In the US, calls made with an autodialler or a prerecorded voice fall under the Telephone Consumer Protection Act (47 U.S.C. 227). For channel detail, see the builder lead generation guide and the wider contractor lead generation guide.

When should a builder hand lead follow-up to someone else?

A builder should hand lead follow-up to someone else when contact rate or old quotes are the weak step and nobody has the hours to chase every enquiry. If you can answer every lead the same hour, keep it in-house: nobody knows your jobs better.

LeadsNow, a Melbourne-based agency, has delivered 50,769+ AI-booked appointments and 1M+ leads, using AI calling, SMS and DM follow-up to book appointments. LeadsNow sees booked-call costs of $30–$400, depending on industry, offer, price and many other variables.

Cheap leads for builders: frequently asked questions

Where can builders get cheap leads?

Builders can get cheap leads from shared marketplaces such as hipages in Australia or Angi in the US, from Google Local Services Ads where available, and almost free from their own old quotes and past enquiries. Compare them on cost per signed job, not cost per lead.

How much does a Google Ads lead cost for a builder?

LocaliQ’s 2026 search advertising benchmarks, drawn from its customers’ Google Ads and Microsoft Ads campaigns, put the average cost per lead for the Home & Home Improvement category at $90.92 (LocaliQ search advertising benchmarks). Treat it as a starting point and track your own number.

Do you pay for Angi leads you never respond to?

Yes. Angi’s own help centre says pros are charged for a lead as soon as both the pro and the homeowner show interest, are charged whether or not they open or respond to the lead, and that each project request is matched with no more than five pros (Angi Opportunities and leads FAQ).

Are hipages leads exclusive to one builder?

No. hipages says every lead is capped at 3 businesses, that the credits needed to accept a lead vary by job category, location, size of job and supply and demand, and that subscriptions start on a 6 month introductory term (hipages membership costs).

What is a good cost per signed job for a builder?

A good cost per signed job is a small share of the contract margin, not a fixed dollar figure. The worked model here runs from about $2,000 to $6,000 per signed job with estimating time counted, which a $40,000 renovation absorbs far less easily than a $600,000 custom home.
