What a contractor has to determine before quoting a water heater replacement here is which fuel the house runs on, and in Mississippi the answer is settled before they knock on the door for most homes. Electricity heats more occupied homes in Mississippi than any other fuel, at 58.9% (2020-2024 ACS 5-year). A house drawing entirely on electricity for its hot water has no flue to inspect and no gas line to trace, so the job turns on whether the existing electrical service can carry the load and whether the unit is sized to keep up with the household's draw. A contractor who misses that spec installs a unit that falls behind from the first week.
A quote for a new water heater depends on what the contractor finds when they open the access and look at what is already running to the unit. Pipe condition, the supply line configuration, and whether the electrical service matches what the replacement draws all have to be checked on site. Half the homes in Mississippi were built in 1986 or earlier (2020-2024 ACS 5-year). A house built before those standards were set may have connections that were code-compliant at the time and now require modification before a new unit can go in. That finding changes the scope of the job, and it is common enough across Mississippi that contractors build assessment time into any first visit.
How does your Mississippi county compare on severe weather?

A water heater installed outdoors or in a garage is exposed to whatever the weather in that county brings, including high wind, lightning and the power outages that follow a storm. A tank unit that loses power will need to be restarted, and a gas unit depends on a venting system that has to stay clear and intact. In a county with a heavier storm record, have a contractor check the water heater's venting, its gas and power connections, and the straps or platform holding the unit in place.
