Market Opportunity in Michigan
Michigan’s climate—heavy snowfall, freeze-thaw cycles, and humid summers—creates constant demand for basement waterproofing, foundation repair, and exterior sealants. The state has over 10 million residents, with 70% living in the southern Lower Peninsula where older homes (pre-1980) often lack modern drainage. Growth drivers include increased awareness of mold and radon risks, plus federal flood insurance rate map updates that push homeowners to protect basements. Detroit alone has hundreds of thousands of historic homes, while booming suburbs like Grand Rapids and Traverse City see new construction needing below-grade waterproofing. The challenge? Seasonality—peak demand is spring thaw and fall rains. But with a proper marketing plan (fall booking for spring work) you can maintain year-round revenue. Michigan’s market is moderately saturated but still underserved in smaller cities and northern rural areas.
State Licensing & Legal Requirements
- Michigan Residential Builder License – Required if you perform work on a residential structure that includes waterproofing as part of a “structural repair.” Issued by the Michigan Department of Licensing and Regulatory Affairs (LARA) – Bureau of Construction Codes. You must pass the NASCLA or Michigan-specific trade exam, provide proof of financial responsibility (e.g., bond or assets), and pay a $350 application fee (initial) plus $150 annual renewal.
- Michigan Occupations Code – Specialty Contractor Classification – Waterproofing may fall under “Waterproofing Contractor” (code 33) or “Foundation/Waterproofing” if included in your scope. LARA offers a limited license for waterproofing only if you don’t do structural work. Check with LARA’s Bureau of Professional Licensing.
- Business Registration – File with Michigan Department of Licensing and Regulatory Affairs (LARA) – Corporations Division. You’ll need a business name (registration fee ~$25), an EIN from IRS, and a Sales Tax License from Michigan Treasury if you sell materials.
- Worker’s Compensation Insurance – Must have if you hire any employees. Obtain from a Michigan-licensed carrier. If you are a sole proprietor without employees, you may opt out but still need a waiver.
- Commercial Liability Insurance – $1 million general liability minimum (common requirement for jobs). Also consider inland marine insurance for tools/equipment.
- Surety Bond – For the Residential Builder License, you need a $10,000 surety bond (LARA requires it). Cost ~$100–$300/year.
- Local Permits – Many cities require a permit for waterproofing excavation (e.g., French drains, sump pumps). Check with the city building department—Detroit, Grand Rapids, Ann Arbor all require permits for below-grade work.
- Radon Mitigation License (optional but recommended) – Michigan requires radon measurement and mitigation professionals to be certified by the Michigan Department of Environment, Great Lakes, and Energy (EGLE). If you offer radon systems alongside waterproofing, get EGLE certification (exam and registration).

Revenue Potential in Michigan
Average job ticket in Michigan for residential waterproofing: $3,500–$7,500 (full basement interior French drain + sump pump). Smaller jobs like single crack injection: $500–$1,200. Exterior excavation waterproofing: $8,000–$15,000.
Market rates by region:
- Detroit Metro (Wayne, Oakland, Macomb): $4,500–$8,000 average
- Grand Rapids / Kalamazoo: $3,500–$6,000
- Ann Arbor / Lansing: $4,000–$7,000
- Northern Michigan (Traverse City, Petoskey): $5,000–$10,000 (higher because of seasonal demand and fewer competitors)
Path to $5k/month: At an average $5,000 job ticket, you need 1 job per month. Achievable in 30–60 days with aggressive local marketing. Path to $10k/month: 2 jobs per month.
