Water Heater Services | Oakland & Macomb County

The short answer

Start with the complete system and the evidence

Water around a heater, inconsistent temperature, and running out of hot water can have different causes. Sandison checks the equipment, demand, supply connections, venting, and controls before comparing repair with a replacement that fits the property.

Repair or replacement evidence

Age matters, but the failure, venting, pressure, and installed condition matter more

Sandison evaluates tank water heaters by fuel type, capacity, recovery needs, leak location, burner or element operation, draft or powered venting, combustion air, electrical supply, relief protection, expansion control, gas delivery, water quality, and the surrounding piping. A leaking tank is materially different from a failed control, heating element, venting defect, or upstream pressure problem. The recommendation explains which condition is confirmed, whether repair is practical, and which code or safety corrections belong in a replacement scope.

System selection

Tank, power-vent, direct-vent, electric, and tankless options have different building requirements

The right water-heating system must fit the property rather than a generic efficiency claim. Sandison reviews hot-water demand, fuel and electrical capacity, vent route, condensate disposal, equipment access, drainage, water hardness, recirculation, and future service needs. Conventional tank equipment can remain the better value in some homes; tankless can provide strong performance where demand, gas supply, venting, water conditions, and maintenance are properly addressed. Commercial applications also require recovery and usage planning that differs from a typical residence.

Common questions

What property owners ask

Does water beneath the heater mean the tank has failed?

The source needs to be located first: nearby piping, a connection, relief discharge, and the tank itself require different responses. Sandison identifies the leak location and connected pressure or drainage conditions before defining the repair or replacement scope.

Should I choose a tank or tankless water heater?

Compare your busiest hot-water use with the available fuel or electrical supply, vent route, drainage, and maintenance access. A conventional tank can fit some homes well, while tankless equipment needs demand and installation conditions that support its output.

Why does our hot water run out sooner than it used to?

Changed demand, burner or element performance, controls, and upstream plumbing conditions can affect delivered hot water. Service checks separate a recoverable equipment problem from a system that no longer matches the household's use.
