5 Things Every Milwaukee Homeowner Should Verify
Most contractor problems are preventable. These checks take under an hour and catch the most common hiring mistakes.
Ask for their WI contractor license number, then verify it yourself at the state licensing website before signing anything.
Request a certificate of insurance. Call the carrier directly to confirm general liability and workers' comp are active.
Get at least three written bids. Any quote more than 30% below average is a red flag, not a deal.
Ask specifically about permit requirements for home addition. A contractor who says "no permit needed" for structural work is a liability.
Read recent Google and BBB reviews for complaint patterns, not just star averages. One-star reviews reveal how disputes get resolved.

Home Addition in Milwaukee: Frequently Asked Questions
How much does home addition cost in Milwaukee?
In Milwaukee, home addition typically ranges from $40,000 to $150,000. Getting three written bids from licensed contractors is the most reliable way to calibrate your specific project.
How long does home addition typically take?
Timeline depends on project scope. Ask for a written schedule before work begins, and specifically ask about material lead times and permit inspection windows: these cause most delays.
Do I need a permit for home addition in Milwaukee?
Home additions always require a building permit. The permit process covers structural plans, foundation, framing, electrical, and final inspections at multiple stages. No licensed contractor will begin an addition without pulling permits — and unpermitted additions must be disclosed in any home sale.
Are addition contractors in Milwaukee required to be licensed?
Yes. Milwaukee enforces active licensure and insurance. Ask any contractor for their license number and verify it at the WI state licensing website before signing a contract.
How do I verify a Home Addition contractor's license in Wisconsin?
In Wisconsin, contractor licensing is tracked by the Wisconsin Department of Safety and Professional Services (DSPS). You can look up any contractor's license status directly at https://dsps.wi.gov/Pages/SelfService/LicenseLookUp.aspx. To file a complaint or check for consumer alerts, use the Wisconsin Attorney General's consumer complaint page at https://www.doj.state.wi.us/dls/consumer-protection/file-consumer-complaint. AboveBoardPros runs this same check before listing a contractor, then reviews it on an ongoing basis.
How does AboveBoardPros select addition contractors?
Four-point check: active registration confirmed against the WI contractor registry, corporate standing reviewed, insurance validated, business reputation analyzed. We reject roughly 40% of applicants and monitor every listed contractor continuously. Credentials that lapse mean removal.
