01Purpose
Each guide helps a visitor name the condition without inventing a diagnosis, preserve useful evidence, avoid transferring a hazard, locate a public process, and compare proposed work. The site cannot decide what an unseen pipe, fixture, heater, drain, or service line requires.
02Source method
Local statements come from current Cohasset water, sewer, public-health, permit, inspection, and drainlayer materials checked during this build. Massachusetts, EPA, and CPSC sources support license, gas-safety, maintenance, and hot-water context. Linked authorities remain controlling because rules can change.
03Business limits
No office, crew, vehicle, completed Cohasset job, customer review, response time, hours, price, warranty, license, insurance policy, or exclusive coverage is presented. A provider that answers the phone must establish its own identity and terms.
04Editorial record
Research, drafting, and review were AI-assisted. No human editorial review is claimed. The final checks screen claims, links, page purpose, repetition, structured data, phone consistency, responsive layout, and release files without pretending to verify a contractor.
