Most contractor websites describe services and show projects — and then ask the homeowner to "call for a quote". Homeowners who are not ready to call leave, search "roof replacement cost", and land on a national content site. Those leads never come back.
Step 1 — Give them a number before they ask for one
Homeowners comparing contractors are in a planning mindset. They want a range, not a sales call. A cost calculator gives them that range in 30 seconds, on your site, with your brand on it. The calculator does not need to be perfect; it needs to be useful enough to keep them on your domain.
Step 2 — Gate the lead after the estimate, not before
Never put a form in front of the number. If a homeowner must enter an email to see an estimate, most will bounce. Show the range first, then offer: "Want local pricing for your project? Leave your ZIP and we'll send options." That two-step flow converts far better than a lead gate.
Step 3 — Respond within the hour
Speed is the single biggest lever in home-services leads. A homeowner who requests pricing at 9am and hears back at 5pm has already called two competitors. Route calculator requests to a shared inbox or SMS alert, and reply with one question: "What's the address? I'll check whether a permit is needed."
Step 4 — Follow up three times
Most requests need three touches: the same-day reply, a two-day follow-up with a ballpark and next step, and a one-week check-in. Contractors who do this consistently convert 2–3x more of the same lead volume.
What to track
- Calculator views vs. form submissions (conversion rate)
- Source page of each request (calculator type)
- Time from request to first response
- Close rate by calculator type
The fastest way to get one on your site
You can build a calculator yourself, install a plugin, or embed a hosted one. A hosted embed takes one line of HTML and gives you 14 calculators (roofing, HVAC, septic, solar, insulation and more) with lead forwarding built in.

FAQ
Do I need a developer?
No. The embed is a single iframe line you paste into any page.
Will it match my brand?
On the Pro and Site plans we apply your brand colors; Site removes our branding entirely.
Who owns the leads?
