Put an independent crawl space cost calculator on your website. Free.
Two lines of HTML and your visitors get a sourced 2026cost range for their square footage and their state — from a source that doesn't sell the job.
Who it's for
Contractors
Show homeowners your quote sits inside the published range — from a source that isn't you. The "let me get three more quotes" objection gets smaller when the number came from somewhere else.
Home inspectors
Give buyers a number when you can't quote the work yourself, without recommending anyone or taking a position on price.
Publishers
Live 2026 data instead of a table you wrote once and have to remember to update.
This is it, running right here
The widget below is the real one, loaded the same way it would load on your site.
The code
Paste this where you want the calculator to appear.
<div data-csr-calculator></div>
<script async src="https://www.crawlspacereport.com/embed.js"></script>The rule
The numbers in the widget are the same numbers on this site. Nobody — free or paid — gets a different range. That's the whole point.
The free version links back to us. That link is how we keep the data free and independent: we don't sell encapsulation, we don't sell leads, and we'd rather be paid in links than in influence over the number.
Pro
Same calculator, no attribution line, priority support. For contractors who want the tool to look like their own.
Questions
- Does it work on WordPress, Squarespace or Wix?
- Yes, and on anything else that lets you paste HTML into a page. It's a div and a script tag — no plugin, no account, no build step.
- Can I change the numbers?
- No, and that's the point. The widget shows exactly what this site shows. If a contractor could tune the range, the range would be worth nothing to the homeowner reading it — and the reason it helps you close is precisely that you didn't set it.
- Does it collect my visitors' data?
- It records the square footage, the condition and the state that were calculated, plus the domain it ran on. No name, no email, no IP-level identity, and no cookies. See our privacy page for the full list.
- Can I remove the attribution link without paying?
- No. The free version links back to us and that link is the price. Pro removes it.
- What happens when the cost data is updated?
- Your widget updates with it, automatically, because it loads from us. You never have to touch the snippet again.
