Notice the signs
Observe
Identify the legal contracting entity, the individual proposed for drainlayer work, the current town roster entry, applicable state trade license, insurance certificate, permit role, and who supervises the site.
Note 33
Place the condition before choosing the work
Protect the room
Safety line
A name on a dated roster is not proof of availability, recommendation, insurance, contract quality, or authority for every plumbing task. Match each credential to the work it legally covers.
Material note
Local boundary
Cohasset says the owner must obtain the connection permit before sewer service or lateral construction begins, and the drainlayer must verify that permit. Confirm the current sequence with the department.
Service flow
Written scope
Put the drainlayer, plumber, excavator, permit applicant, traffic or utility coordinator, inspector, restoration party, and contracting entity in one responsibility table. Avoid accepting a borrowed license number.
Close the loop
Verification
Before work starts, verify current status through official channels; at closeout, retain the issued permit, inspection, as-built route, test, and signed invoice from the entity that actually contracted the work.
