Free Tool for Contractors

A free remodel cost calculator for your website.

Homeowners want a ballpark before they call. Give them one — with your own pricing — and collect their contact details in return. One copy-paste, no plugin, no cost.

Live Demo

What your visitors see.

Five quick steps, then a contact form before the price is revealed — the same lead-capture pattern we build into custom contractor sites. Try it: this demo sends its leads to us, yours will go to you.

  • Room, size, finish level — kitchen, baths, basement, whole-house, additions and more.
  • Smart follow-up questions — what kind of addition, whether the plumbing moves, load-bearing walls, a basement bathroom — the things that actually swing the price, each priced in automatically.
  • Three finish tiers with real products — homeowners see exactly what "budget" vs "high-end" means, and you can rename the brands to what you actually install.
  • Your rates, not ours — set your own $/sq ft for every room and tier. Change them any time.
  • Contact details before the number — name, phone and email land in your inbox with the full estimate.
  • Matches your site — pick an accent color; the widget is sealed off from your theme's CSS so nothing breaks either way.

Free remodel cost estimator by The Digital Keystone — website design & SEO for contractors.

How It Works

Three steps. About five minutes.

1. Set your rates

Enter your business name, the email leads should go to, and your price per square foot for each room and finish level. We pre-fill national averages so you can just adjust.

2. Paste the code

Copy three lines into any page — WordPress, Squarespace, Wix, Webflow, plain HTML. No plugin to install, nothing to maintain; updates roll out from our end automatically.

3. Leads hit your inbox

Every completed estimate is emailed to you with the homeowner's name, phone, email, the project and the range they saw. We don't keep their details — they're your lead, not ours.

The four screens a homeowner moves through: room, details, finish level, and the estimate they see after leaving their contact details.

Why it's free: the code includes a one-line credit linking back to The Digital Keystone. That link is the whole deal — it stays, and in exchange you get the tool, hosting and updates at no cost. Want it fully white-labeled, or built around your exact services? That's a custom build — let's talk.

Follow-up questions & their price adjustments pre-filled — change any number you like

After choosing a room, the homeowner answers two or three quick questions. Each answer either scales your $/sq ft rate by a percentage or adds a flat amount (by finish level) — so a kitchen addition on a second story prices very differently from a ground-floor bedroom. The defaults are filled in; adjust anything to match how you price. The wording stays the same.

FAQ

Questions contractors ask.

01Is it really free?

Yes. There is no charge, no trial and no upsell inside the widget. The only condition is the one-line credit that links back to The Digital Keystone — that link is how we get paid, in the form of exposure. If it is removed, the calculator re-adds it.

02Where do the leads go?

Straight to the email address you enter when you generate the code — every completed estimate, with the homeowner's name, phone, email, the project details and the price range they were shown. We relay the email; we do not store the homeowner's details or contact them.

03Can I change my prices later?

Any time. Come back to this page and run the generator again with the same email address. Your existing embed code keeps working and starts using the new rates on the next page load — nothing to re-paste.

04Will it slow down my website or clash with my design?

No. It is one small script that loads after your page, and it renders inside its own sealed container, so your site's styles cannot break it and it cannot affect anything else on your page. You choose the accent color so it fits.

05How accurate are the estimates?

As accurate as the rates you enter. The widget shows a range of about 15% either side of your price per square foot, clearly labeled as a preliminary estimate rather than a quote. The defaults are national averages from major cost guides — most contractors adjust them to their market.

06Can I get one without the credit link, or built around my exact services?

That is a custom build rather than the free tool — a calculator designed around your services, pricing model and brand, hosted on your own site. It is one of the things we do most often for contractors; get in touch and we will scope it.

Want a calculator built around your exact services?

Roofing, pools, additions, insurance restoration — we build custom estimators, before/after sliders and lead-capture tools into contractor websites every week.
