Which Wisconsin plumbing licenses cover the acquired services?
Section 145.06 requires personal authority for covered work and lists specific exemptions. Licensed plumbers, registered apprentices and pipe layers have distinct roles. Test actual drain, water, repair and installation tasks before treating one credential as sufficient for every service.
The DSPS master-plumber page confirms the individual credential and lists application and renewal resources. Get current master, journeyman, restricted and registered-worker records. Match each person to real duties and sold services. A crew roster alone cannot prove the proper scope.
Use the market hub to assess buyer fit. Crew management and deal funds cannot supply personal credentials. Flag work needing new people or approval. Forecast capacity from real roles and an accepted plan.
How should ownership and licensed-master supervision be arranged?
The statute puts a licensed master in charge of covered installations, responsible for proper work. It also addresses people who superintend plumbing within firms. Map real duties, employment and credentials. Confirm the future master role before agreeing that the seller may leave.
Assets cannot convey a personal license; shares cannot qualify an unlicensed owner to supervise. Give DSPS the future firm and people. Ask what fits those facts. A purchase label cannot fill the required trade role.
Use the qualifying-party definition to assess reliance on one master. Set real supervision, availability, backup staff and an accepted permit handoff. Retained equity cannot itself fill that role. Include its continuing pay and replacement cost in the supported earnings forecast.
Which license-transfer and entity changes require confirmation?
Section 145.06 makes plumbing licenses individual and nontransferable. It also limits use of a master's license by others. Informal consent to use the departing seller's number is insufficient. Build authority through the right people and roles, with the required records accepted.
Ask DSPS about changed employment, names and responsible people. Check entity registration, customer terms and permits separately. A corporate filing cannot update every job record. Track responses and missing proof for each changed role.
Assign each requirement an owner and acceptance proof. Mark work that must pause if a role remains open. Keep that decision separate from asset and liability allocations. Purchase economics cannot permit the next job.
What can comity or reciprocity resolve for an outside buyer?
The master page lists out-of-state comity with examination. Check the exact credential and current route for the proposed supervisor. A listed pathway cannot establish an automatic exam waiver. Issued Wisconsin authority still matters before covered work begins under the buyer's plan.
Get standing, test history, experience and current forms. Ask DSPS which route fits and what remains due. A prior credential supports review. It cannot supply an issued record or complete every local work requirement.
Confirm issuance and supervision before seller release. Pending tests belong in the schedule and fallback plan. Set dates from accepted records. A preferred deadline cannot guarantee agency timing or make the intended master ready.
Which registration, insurance, bond, and permit questions remain?
Match business registration and names with actual work. Ask whether broader building or residential improvements need further credentials. A plumbing license cannot replace every business or construction requirement. Check proposed expansion separately before counting new services in the buyer's forecast.
DATCP's consumer guidance discusses dwelling-contractor credentials and liability or bond proof in its general-construction context. Confirm applicability to the actual work. Do not impose that same route on every plumber. Project contracts can separately require security that needs its own budget review.
For open work, identify the permit holder and issuer. Ask what changed ownership, employer or master requires. Preserve accepted updates and pending inspections. A transferred job file cannot prove that the future firm may finish and collect the balance without further action.
| Review field | Primary resource | Buyer decision |
|---|---|---|
| Personal authority | Section 145.06 | Who can perform and supervise covered work? |
| Master application | DSPS credential page | What current route and evidence apply? |
| Worker coverage | DWD employer guidance | Which staffing facts trigger coverage? |
| Commercial plans | Delegated-agent list | Which authority reviews the project? |
| Customer contracts | DATCP guidance | What agreements and notices need correction? |
How do plan reviews and inspections affect open jobs?
The DSPS delegated-agent list, dated September 21, 2026, identifies specified commercial plan-review powers. Jobs outside a listed delegation use the applicable DSPS route. Match the project type to its actual reviewing authority. Not every city handles every review.
Commercial inspections are a separate question. Municipalities with properly certified inspectors may inspect without plan-review delegation. Absence from the delegated-agent list therefore cannot prove a city lacks inspection power. Ask the actual issuer which accepted reviews and inspections remain due for each project.
Get plans, permits, inspections, repairs, labor and parts still due by job. Confirm the issuer's accepted handoff. Budget completion before treating balances as free cash. The buyer may have to spend first to collect final payment.
Which consumer contracts and customer obligations require review?
DATCP describes written contracts when covered improvement payments precede completion, lien-waiver notices and cancellation for specified solicited off-premises sales. Counsel should test actual sales facts, terms, notices and exceptions. These duties cannot be applied identically to every repair invoice without reviewing scope.
Get signed estimates, changes, deposits, finance charges, warranties and complaints. Determine who owes each promise and whether consent is needed. Match that firm and licensed people across customer, permit and dispatch records. Closing terms should name the party who completes unresolved work.
Consider a hypothetical deposit for a future installation. Labor and parts remain due after receipt. Assign the work and funding before treating cash as seller proceeds. Include disputes and correction cost in the opening budget. This illustrates planning rather than a reported completed transaction.
What workforce and worker-classification evidence should buyers collect?
DWD's guidance requires insurance when the third employee starts. Another trigger covers at least one employee and $500 in combined quarterly wages for Wisconsin work. Coverage is due by the next quarter's first month's tenth day, subject to applicable exceptions.
Match staff and pay periods to the triggers. Get duties, hours, owner ties, subcontracts, claims and policies. Ask about the future employer and crew. Small payroll or owner titles cannot alone prove no coverage is due.
Use the worker-misclassification definition to frame counsel's review. Contractor labels and tax forms cannot settle the facts. Include recurring labor and coverage in earnings. Treat possible past exposure through separate diligence and purchase terms, rather than simply remove the cost as an add-back.
Which named buyer evidence is relevant to Wisconsin?
Redwood's April 7, 2025 release reports its Cardinal Heating, Cooling, Plumbing, & Electric partnership in Madison. It describes retained minority ownership and the continuing brand. This is dated first-party deal and footprint evidence. Terms for a different seller remain unproved.
The announcement proves no current offer, undisclosed price or requirement to retain equity in another deal. Compare territory, services, crew, master dependence and management. Verify interest and decision authority before controlled disclosure. Assess the actual buyer's plan for this company's future work and duties.
Use private equity and valuations, consolidation trends and skilled-trades labor for the wider review. A reported partnership cannot supply a multiple for another firm. Compare supported earnings and actual offers, with each buyer's proposed staff, funds and terms.
What structure and timeline should govern the closing sequence?
Set closing from accepted roles and completed handoffs. Price agreement cannot settle licenses, permits, coverage or customer promises. Give each open item an owner and proof condition before relying on the forecast or releasing the seller.
- Map services and people. Reconcile work and revenue to current crew credentials, actual master supervision, and excluded activities.
- Confirm the operating route. Give DSPS and local authorities the proposed ownership, employment, and personnel changes. Assign applications, examinations, and accepted record updates.
- Secure continuity and protection. Arrange licensed responsibility, employer coverage, applicable registrations, project security, and permit handoffs with documented evidence.
- Reconcile unfinished obligations. Allocate customer receipts, remaining work, inspections, corrections, warranties, and disputes. Confirm that opening cash funds those commitments.
- Verify the handoff before seller release. Check credential status, accepted supervision, job records, dispatch access, and customer responsibilities. Give every outstanding task an accountable owner.
