Shared insulation leads are sold to several contractors at once, usually three to five, while exclusive leads go to one. Exclusive leads cost more per lead but usually less per booked job. Pay-per-appointment and guaranteed-estimate models shift the risk to the vendor. Compare every model on cost per booked job, not cost per lead.
Quick answer: A shared insulation lead is sold to several contractors at once, usually three to five. An exclusive lead is sold to one contractor only. Exclusive leads cost more per lead but typically cost less per booked job. Pay-per-appointment models go further by making the vendor carry the risk.
Last updated: 2026. This guide is written by Growth Partner, marketing for insulation contractors, for owners in Canada and the United States who are deciding how to buy leads. We compare exclusive vs shared leads for insulation contractors on one metric: what you pay for a booked job.
A shared lead is sold to multiple contractors, while an exclusive lead is sold to one. According to Blueprint Lead, shared leads are usually sold to three to five contractors at once. That single difference changes your close rate, your pricing power and your time cost.
A shared lead is a homeowner enquiry, such as a request for attic insulation or spray foam, sent to several contractors simultaneously. The homeowner often gets a flood of calls and texts within minutes. The first contractor to respond has the edge, and the rest compete mostly on price.
An exclusive lead is an enquiry delivered to one contractor only. You are the only company the homeowner expects to hear from. That means no speed race, less price shopping, and a better chance to earn trust in the first conversation.
Pay-per-appointment means you pay for a booked, pre-qualified appointment rather than a raw enquiry. The vendor handles the screening and carries the risk of unqualified contacts. It sits one step further down the funnel than a lead.
| Factor | Shared lead | Exclusive lead | Pay-per-appointment |
|---|---|---|---|
| Who receives it | Three to five contractors | One contractor | One contractor |
| What you pay for | An enquiry | An enquiry | A booked appointment |
| Who carries the risk | You | Mostly you | Mostly the vendor |
| Typical weakness | Speed race, price pressure | Higher cost per lead, exclusivity claims to verify | Qualification terms must be defined |
Usually not, unless you have a dedicated inside-sales team and lower-ticket jobs. Shared leads look cheap per lead, but 99 Calls, which serves insulation businesses in the US and Canada, describes shared platforms as cheap per lead and costly per job.
Use this formula, which BaaDigi also uses: cost per booked job = cost per lead divided by close rate. A cheap lead that rarely closes can cost more per job than an expensive lead that often does.
Close-rate claims vary widely and are not independently verified. Spray Foam Genius Marketing says shared leads often convert at 5-10%, while exclusive or inbound leads can reach 20-40%. That is a vendor claim. Treat it as a range to test, not a promise.
Exclusive leads typically cost two to four times more than shared leads in home services, according to Made For Builders. Actual prices depend on your market, job type and vendor. We do not quote a universal price because published figures are inconsistent. Ask any vendor for their method in writing.
The vendor can sell the lead only once, so the price has to cover what several sales would have earned. You are also paying for less competition and a higher chance of a real conversation.
Cost per lead (CPL) is what you pay for an enquiry. Cost per booked job is what you pay to win a sale. Cost per acquired customer adds sales time, inspections and overhead. Always compare vendors on the same metric.
Note that some vendors publish a stated method for CPL, as 99 Calls does, while others, such as ClearCut, publish no rate card. Ask before you commit.
The numbers below are illustrative placeholders only, not market data. Replace them with your own.
| Input | Shared lead (example) | Exclusive lead (example) |
|---|---|---|
| Cost per lead | $40 | $120 |
| Close rate | 8% | 25% |
| Cost per booked job (CPL / close rate) | $500 | $480 |
| Inspection time per estimate | 60 minutes | 60 minutes |
| Estimates needed per job | 12.5 | 4 |
In this example the cost per booked job is similar, but the shared model needs about three times as many inspections. That time is the hidden cost. Spray foam jobs usually carry a higher ticket than attic top-ups, so they can justify a higher cost per lead. Calculate your maximum affordable cost per lead as: average job value x gross margin x target spend share x close rate.
Get it in writing. An exclusive lead should go to one contractor, never be resold, and be clearly described to the homeowner. Blueprint Lead's test centres on a written agreement, whether passed leads are resold, and whether the homeowner knows which company is coming.
It can be, but treat it as one channel, not a growth engine. HomeStars is the best-known home services marketplace in Canada, yet its shared-lead model carries the same speed and price pressure described above. Insulation-specific data is scarce, so test it with a cap on spend.
According to The Iconic Management, which cites a third-party blog, HomeStars Premium runs about $200 a month, new contractors see 2-4 leads a month, and shared leads close at roughly 10-20%. Treat these as estimates, not verified figures. Do the math with your own average job value before you renew.
| Factor | Canada | United States |
|---|---|---|
| Main marketplaces | HomeStars | Angi, HomeAdvisor, Thumbtack, Porch, CraftJack |
| Currency | CAD | USD |
| Lead model | Mostly shared, subscription-based | Mostly shared, pay per lead |
| Language | English and French (Quebec) | English, with Spanish in some markets |
| Incentives to mention | Canada Greener Homes and provincial rebates | Federal and utility rebates and incentives |
In both countries, Angi and HomeAdvisor-style platforms follow the same logic: low price per lead, many competing contractors. Run the cost per booked job calculation before deciding.
In Quebec, bilingual ads and landing pages matter. Your content should work in both French and English.
Pay-per-appointment is a model where you pay for a pre-qualified appointment on your calendar, not a raw enquiry. It works when the vendor defines "qualified" clearly and carries the risk of no-shows or poor fits. Coverage for North American insulation is thin; the one competing page we found is a UK vendor priced in GBP.
With pay-per-lead, you pay when an enquiry arrives, whether or not the homeowner is serious. With pay-per-appointment, you pay when a screened homeowner agrees to meet you. The second model removes much of the intake burden, but the contract must define what counts.
A guarantee of leads is not a guarantee of qualified estimates. A lead replacement policy only credits you for bad contacts. A written estimate guarantee commits the vendor to a number of qualified estimates, with a refund if they fall short. Growth Partner offers guaranteed qualified estimates in writing or your money back: a set number of qualified estimates, or a 100% refund.
It depends on your team, cash flow and capacity. Buying leads is faster to start but you rent the demand. Owned demand takes longer but compounds. Minyona argues cost per lead is the wrong metric, and Made For Builders points to owned demand as the longer-term pivot.
| If you are... | Choose... |
|---|---|
| A small crew with no one to answer calls fast | Exclusive leads or pay-per-appointment |
| A team with dedicated inside sales and low-ticket jobs | Shared leads, with tight tracking |
| Selling high-ticket spray foam jobs | Exclusive leads, ads or guaranteed estimates |
| Wanting predictable calendar volume without risk | Guaranteed qualified estimates |
| Planning for the long term | Local SEO plus Google Ads, with leads as a supplement |
Work backwards from revenue. Divide your target by average job value to get jobs needed, divide jobs by close rate to get estimates needed, then divide estimates by your lead-to-estimate rate to get leads needed.
Illustrative example (placeholders, not benchmarks): a $500,000 target with a $5,000 average job needs 100 jobs. At a 25% close rate that is 400 estimates. At a 50% lead-to-estimate rate, you need 800 leads. Change any input and the answer changes sharply, which is why you should use your own data.
Minyona notes attic and spray foam buyers differ. Attic buyers are often driven by comfort, energy bills or rebates and may compare prices. Spray foam buyers are often renovating or building and care more about performance. Spray foam typically has a higher job value, which supports a higher cost per lead, but sales cycles can be longer. Run each service line separately. Speed to lead matters for both: respond in minutes, not hours.

Shared leads are usually sold to three to five contractors at once, according to Blueprint Lead. The exact number depends on the platform and market. Ask any vendor to state the maximum number of recipients in writing, because more competitors means a lower close rate and more price pressure.
Not always. Exclusive leads usually close better and cost more per lead, but shared leads can work if you have a fast inside-sales team and smaller jobs. Compare both on cost per booked job, using your own close rate rather than vendor claims.
Published ranges are vendor claims and vary by market. One vendor says shared leads convert at 5-10% and exclusive leads at 20-40%. These are unverified. Track your own lead-to-estimate and close rates by source for at least a quarter before judging any channel.
Divide your cost per lead by your close rate. For example, a $100 lead at a 20% close rate costs $500 per booked job. For a fuller picture, add inspection time, travel and sales labour to get your cost per acquired customer.
It can be, with limits. One third-party estimate puts HomeStars Premium at about $200 a month, with 2-4 leads a month for new contractors and 10-20% close rates on shared leads. Treat those as estimates, cap your spend, and measure cost per booked job.
Pay-per-appointment means you pay for a pre-qualified, booked appointment instead of a raw enquiry. The vendor screens homeowners and carries more of the risk. Make sure the contract defines what counts as qualified, such as ownership, service area, project type and confirmed budget.
It means a vendor commits in writing to deliver a set number of qualified estimates, with a refund if they do not. It differs from guaranteed leads, which only promise enquiries. Growth Partner offers this guarantee with a 100% refund if the number is not met.
Sometimes. Many vendors offer credits, not refunds, and only within a short window. ClearCut Leads cites a 48-hour window for flagging bad leads, which is a vendor claim. Get the refund or credit terms, and the definition of a bad lead, in writing before you sign.
