Finding a contractor for your home improvement project is crucial for ensuring quality work, fair pricing, and a smooth experience. This comprehensive guide outlines nine essential steps Wisconsin homeowners should take when searching for and vetting contractors. By following these guidelines, you’ll be better equipped to identify a reliable contractor and avoid common contractor scams from unscrupulous “storm chasers.”
1. Clearly Define Your Project Needs

- Outline exactly what your construction project involves before contacting contractors.
- Create a detailed description to ensure all bidders are quoting on the same work.
- Include materials preferences, design details, and timeline expectations.
- Prepare details upfront to prevent misunderstandings and reveal which contractors truly listen to your vision.
- Having clear scope helps get accurate quotes and makes fair comparisons possible.
2. Ask for Recommendations & Check Reviews
- Start with real experiences of other homeowners – ask friends, family, and neighbors.
- Personal referrals are often most reliable to help find a trustworthy contractor.
- Check online reviews on Google, Facebook, and the Better Business Bureau.
- Look at overall star ratings and number of positive reviews.
- Review the contractor’s social media presence to gauge their culture and responsiveness.
- Leverage both personal networks and online resources to identify well-recommended professionals.
3. Verify Licenses, Certifications, and Insurance
- Never take qualifications at face value – always verify them.
- In Wisconsin, licensed contractors need a Dwelling Contractor Certification to pull permits.
- Request state credentials or license numbers and confirm through Wisconsin Department of Safety and Professional Services.
- Ensure contractors carry proper liability and workers’ compensation insurance.
- Ask for a certificate of insurance and call providers to confirm active policies.
- Proper licensing and insurance protect you from liability if accidents occur.
- Only hire licensed and insured professionals to reduce risk.
4. Check References and Past Projects
- Request references from recent customers you can contact.
- Call references and ask specific questions about their experience:
- Did the contractor finish on schedule?
- Was the quality of their work up to expectations?
- Did they communicate well and clean up after the job?
- Would they hire the same contractor again?
- Review the contractor’s portfolio of past projects they’ve completed.
- Consider visiting a current job site if possible.
- This verification confirms the contractor delivers on their promises.
5. Get Multiple Quotes and Compare Fairly
- Get at least 2–3 estimates from different contractors.
- Ensure each contractor is bidding on the same scope of work.
- Be wary of an extremely low bid – it could indicate missed scope, subpar materials, or future change orders.
- Have contractors visit your home to inspect in person rather than providing phone quotes.
- Choose based on value and completeness, not just price.
- Multiple quotes help you understand the market rate and spot outliers.
6. Insist on a Written Contract (and Read It)
- Get the agreement in writing before work begins.
- Contracts should include work description, materials, start/finish dates, payment schedule, and warranties.
- A comprehensive contract protects both parties by clearly outlining expectations.
- Don’t rely on oral agreements – they can be forgotten or misinterpreted.
- Wisconsin law requires written contracts when payment is required upfront.
- Take time to understand every clause, asking questions if needed.
- Confirm the contract includes provisions for disputes, work guarantees, and final payment terms.
7. Look for Local Presence and Professional Affiliations
- Choose contractors with an established local business address (not just a P.O. box).
- Contractors with local roots have a reputation to uphold in the community.
- Check for membership in professional groups like the National Association of the Remodeling Industry (NARI), Home Builders Association, or BBB accreditation.
- Professional affiliations indicate commitment to industry standards.
- Contractors with a local, permanent address are more likely to be available if issues arise later.
- Fly-by-night contractors often lack local roots and permanent locations.
8. Gauge Communication and Professionalism
- Pay attention to how the contractor communicates from the first interaction.
- Note whether they respond promptly to your calls or emails.
- Observe if they show up on time for appointments and listen carefully to your needs.
- Good communication is critical for a successful project.
- Consider your comfort level – you should feel heard and understood.
- For longer projects, you’ll be in close contact with this general contractor.
- Professionalism shows in the details, like providing written estimates, being polite, and maintaining a professional appearance.
- Trust your instincts – hire a good contractor who makes you feel confident.
9. Watch for Red Flags and Scams
- Be cautious of unsolicited doorknockers offering repairs, especially after storms.
- Reputable contractors rarely find work by going door-to-door.
- Avoid contractors using high-pressure sales tactics like “today-only” discounts.
- Never pay large full payments upfront before work begins.
- Be wary if a contractor cannot provide basic information like physical address or references.
- Fair contractors schedule payments tied to progress with the final payment upon completion.
- Listen to your gut – if something feels off, it probably is.
