About Twin Ports Contractors

A local directory of contractors in Northeast Minnesota and the Twin Ports, with the official state license status on every licensed listing.

Who runs it

Twin Ports Contractors is run by Tech Stars University in Duluth, MN.

Where the data comes from

• Minnesota Department of Labor and Industry (MN DLI). Public license and registration files. We keep businesses in this region with an issued license or registration. This build uses files downloaded November 12, 2026.
• Google Maps. Phone, website, rating and review count, checked November 12, 2026. For a licensed business, we accept a Google listing only when its phone number and name, or its exact name, match the license record.
• Businesses found on Google only. We also search Google Maps by trade and town. A business found that way, with no license record matched, is listed without any license status, and its listing says so.
• The business's own website. Services, towns served and free estimates are shown only when the business's website states them.

Right now the directory holds 1183 listings. 894 hold a MN DLI license, 78 hold a state registration or bond only (not a license), and 211 were found on Google with no license record matched. 599 listings carry Google data.

Updates

Every listing shows the date its details were last checked. The state updates its license files daily, so always confirm a license on the official MN DLI lookup before you hire.

Our rules

• A business is listed under a trade only when its license or its Google category supports it.
• We never invent details. If a fact is not in our sources, the field stays empty.
• For sole proprietors and businesses without a public storefront address, we show the city only.
• We do not publish personal email addresses.
• We show a Google rating and review count with its date. We do not copy reviews or photos.
• If the state file shows an enforcement action, the listing says so in neutral words and links to the official record. We add no comment.
• Featured listings are always labeled "Featured".
