Wisconsin Contractor License Lookup & Leads Scraper

Pain points

• Wisconsin's state licence lookup (DSPS LicensE) shows a name and a credential, no phone or address, one search at a time.
• Milwaukee publishes its licensed home improvement contractors as a 34-page PDF (checked 2026-11-06), not a spreadsheet.
• Madison's licensed and prequalified contractors sit in a report viewer, split into three categories and some 90 work tasks.

What we solve

• Three rosters in one dataset: 1,205 Milwaukee home improvement licences, 363 Madison City Engineering firms and 1,604 DNR well and pump licences (November 6, 2026).
• One clean table: business, licence number where the source has one, trade(s), expiry, phone, street address (Milwaukee, DNR) and email (Madison, DNR).
• Filter by locality (Milwaukee, Madison, Statewide) and by trade, and by expiry date; look up a name or licence number across all three.

Summary

Wisconsin contractor licences with contact details, from the three public rosters that publish them. Milwaukee: every home improvement contractor the City licenses (1,205 licences on November 6, 2026), with licence number, expiry, business, licensed agent, street address and phone (phone on 1,203). Madison: every firm City Engineering licenses for right-of-way work or prequalifies for public works and utility work (363 firms), with the work tasks it is approved for, phone and email (352 each) and expiry; Madison publishes no address or licence number. Statewide: the Department of Natural Resources' well drillers, pump installers, heat-exchange drillers, well filling and sealing and property-transfer well inspectors (1,604 licences; one row per licence carrying every DNR directory it is in), with licence number, phone, mailing address and email (1,549). The state's own DSPS lookup publishes no contact, so it is not used; this actor adds other Wisconsin cities as they are read. Exports read a stored copy; lookups read the rosters live. Pay only per row returned.

Who it's for

• Building-material suppliers, lenders and insurers selling to licensed home improvement contractors in the Milwaukee area
• Utilities, engineering firms and general contractors finding Madison-approved subcontractors by work task
• Pump, well-equipment and water-treatment suppliers reaching Wisconsin's licensed well drillers and pump installers
• Homeowners and property managers checking a contractor's Milwaukee licence and expiry

Limitations & updates

Covers three rosters, not every Wisconsin contractor: Milwaukee home improvement licences (1,205), Madison City Engineering firms (363) and DNR well and pump licences (1,604), as read on 2026-11-06. State DSPS trades (dwelling contractor, electrical, plumbing, HVAC) are not included. Madison has no address or licence number; Milwaukee has no email; DNR has no expiry. Exports come from a stored copy (its date is in the run log).

FAQ

Where does the data come from?

Milwaukee: the City Clerk's List of Valid City of Milwaukee Home Improvement Contractors (staticwebfiles.milwaukee.gov), regenerated daily. Madison: City Engineering's Prequalified Contractor List report (cityreports.cityofmadison.com), categories A, B and C. Statewide: the DNR's drilling and pump installing service directories (dnr.wisconsin.gov/topic/Wells/Contacts.html). Exports read a stored copy (the run log gives its date); lookups read the rosters live and fall back to the stored copy.

Does it cover all of Wisconsin?

Not for every trade. Wisconsin licenses dwelling contractors, electricians, plumbers and HVAC statewide through DSPS, whose public lookup shows no phone or address; those state licences are not included. This actor reads the rosters that publish contact: Milwaukee's home improvement licences, Madison's City Engineering approvals and the DNR's statewide well and pump licences. More Wisconsin cities are added as they are read.

Which fields does each roster have?

Milwaukee: licence number, expiry, business, licensed agent, street, city, ZIP, aldermanic and police district, phone; no email. Madison: firm, work tasks, approval category, phone, fax, email, expiry; no address and no licence number. DNR: licence number, name (person or business), phone, mobile, mailing address, email, county; no expiry.

Are expired licences included?

The sources list current licences only. Status is derived from the expiry date (Milwaukee, Madison); a DNR row is Active while the DNR lists it. Filter on Expires on or after / before to target renewals.

How do I look up a firm or a licence number?

Put names or licence numbers in queries and set mode to lookup. A name matches if it is contained in the business name; a number (HICN 0205318, a DNR licence no.) matches exactly. Lookups read all three rosters live.

How am I charged?

One event per row returned. Notices are free.

Works with AI assistants (MCP)

Callable as an MCP tool, so Claude, Cursor, VS Code Copilot and other MCP clients can run it directly. Grab the config from the MCP tab on this page — Apify hosts the server and keeps that snippet current, and OAuth signs you in on first connect, so no API token goes in your config file.

Then just ask:

"List home improvement contractors licensed in Milwaukee, Wisconsin, with their street address, phone and licence expiry."

That is Trade Home Improvement Contractor (1,205 licences on 2026-11-06). Keep maxResults small on a first call. Runs started this way bill exactly like any other run.

Data & lawful use

This actor collects publicly available information that the City of Milwaukee (City Clerk's License Division), the City of Madison (City Engineering) and the Wisconsin Department of Natural Resources (DNR) publishes for public lookup — licence records, business listings and the contact details professionals list there. Some of it identifies individuals (sole proprietors, licence holders, agents), so treat any names, phone numbers and emails in your results as personal data.

When you run this actor, you decide what is collected and what it is used for, so you are the controller of that data and we act only as your processor (Apify Standard Actor Contract). You need a lawful basis for your use, must honour opt-out and deletion requests, and must follow the marketing rules that apply to you (CAN-SPAM, TCPA, GDPR, CCPA and similar). Don't use the output for unsolicited bulk messaging, for screening covered by the FCRA, or for anything the source's own terms forbid.

Your results are stored in your own Apify account. We don't keep a copy of your results and don't sell or share them.
