Where leaks show up in Mooresville
Where the unit sits decides how urgent a leak is, and in Mooresville that is not uniform. The Lake Norman side and the newer subdivisions are garage and closet installs, frequently with attic units in the larger homes. The pre-1950 mill village stock is crawlspace-dominant with tight clearances, and we price that access separately and tell you before the visit rather than after.
That matters more than the leak itself. Water escaping from a unit in a garage is an inconvenience. The same leak from an attic or an upper-floor closet is a ceiling, and it is the one case where we would rather you shut the cold inlet and call than wait for the morning rate.
- From the tank body: the unit is finished. A perforated shell cannot be patched, and anyone who says otherwise is selling you a delay.
- From the relief valve discharge: usually pressure rather than a failed valve. Put a gauge on a hose bib before replacing anything.
- From a fitting or connector: genuinely repairable, and frequently a $150 to $300 job rather than a replacement.
- Pooling with no obvious source: often condensate or the pan drain rather than the heater, which is worth establishing before anyone quotes you a tank.

What Mooresville itself changes
The housing in Mooresville
Mooresville is genuinely two markets and one description will not cover both. The town-wide median build year is 2006, which puts the bulk of the housing in its first replacement cycle. But the 28115 ZIP holds around 1,562 homes built before 1950, clustered around the historic mill village, and those properties have completely different plumbing, different access and different failure modes. We ask which side of that line you are on before quoting anything.
The pipe era
The 2000s stock is copper and PEX. The 1980s and 1990s subdivisions sit inside the polybutylene window and some still have it. The pre-1950 mill village properties are the ones where galvanised supply may still be in service, and galvanised corrodes inward, restricting the whole house rather than just the hot side.
