What the reviews say
Water heater feedback Reviewers praised same-day and Sunday or holiday response, a clean swap of a leaking tank (with an upsize to 50 gallons), and fair prices for repeat customers.
Worth knowing Yelp reviewers said a technician recommended a replacement costing over $1,000 where another company later fixed a wire and cleaned the unit (2019), and that an $85 diagnosis quote became $285 an hour on arrival (2023); the owner replied to the latter that the company would take the concerns into consideration.

97%Single-family homes
About 32% of homes were built since 2010, so many original water heaters are reaching the age when replacement planning makes sense.
91% of homes heat with utility gas, so gas water heaters with existing venting are common here.

PERMITS & LICENSING
Permits and licenses in St. John.
Permits and who issues them
Apply for permits in St. John on its Cloudpermit portal, by email to permit2@stjohnin.gov, or in person. Building permits take at least two working days. The town's pages cover additions, remodels, roofs, garages and decks but not water heaters, so ask Building & Planning whether a replacement needs a plumbing permit.
The town posts lists of registered general, electrical, tree service and roofing contractors, so contractors seem to register with the town. We didn't find rules for plumbers.
