Notice the signs
Observe
Ask each provider for its legal name, exact licensee and number, insurance evidence, Cohasset coverage, service charge, estimator role, subcontractors, permit responsibility, and written basis for the recommended work.
Note 44
Place the condition before choosing the work
Protect the room
Safety line
Do not share payment credentials, entry codes, or sensitive household information before the recipient is identified. Gas odor and immediate danger require emergency paths, not estimate shopping through this number.
Material note
Local boundary
Check Massachusetts license status in the official lookup, then verify any separate Cohasset drainlayer or permit role with the town. A referral connection does not endorse or validate the company that answers.
Service flow
Written scope
Normalize proposals for endpoints, material, access, protection, shutdown, public coordination, permits, tests, cleanup, surfaces, schedule, payment, exclusions, change orders, warranty limits, and evidence delivered at closeout.
Close the loop
Verification
Before choosing, write down the unresolved assumptions in each bid and ask what finding would change the method or price. At completion, match the invoice, inspection, tests, photos, and warranties to the accepted scope.
