Lexington has some of the oldest houses in the region, so original galvanized steel and decades-old copper are common reasons to repipe here. Replacing the supply lines with PEX or copper ends the cycle of leak after leak and restores pressure lost to corrosion.

Lexington's older housing and city water
About 68% of Lexington homes were built before 1980, and roughly 14% before 1940, per Census survey data; the median house dates to 1969. Neighborhoods such as the Uptown Lexington Historic District, the Lexington Residential Historic District and the Erlanger Mill Village Historic District reflect the city's textile and furniture past. Houses of that age often started with galvanized steel supply pipe, and many have been patched over the years with whatever was standard at the time.
The city runs its own water system, drawing from Lake Thom-A-Lex and treating with chlorine. Its 2025 water quality report shows no violations, a 90th-percentile lead result of 0 ppb in the latest sampling, and a full service line inventory posted online and available at City Centre. The report also says the City is responsible for removing lead service pipes while residents share responsibility for the plumbing in their homes. Whatever the inventory shows outside, the pipe inside your walls is yours to evaluate.
Repair, partial repipe or full repipe
| Approach | Best fit in Lexington | Keep in mind |
|---|---|---|
| Fix the leak | A single failure in a home that was replumbed in the last few decades | Doesn't help if the remaining old pipe is corroded |
| Replace a section | One bathroom group, or the main trunk line in the crawl space | Old and new pipe stay in service side by side |
| Whole-house repipe | Original galvanized in a pre-1960 house, or repeated failures in several rooms | Largest job, but every run is new at once |
Signs to watch for
- Tan or orange water when a tap that hasn't been used for a while is opened
- The far bathroom or upstairs fixtures losing pressure first
- Galvanized pipe that has been cut and spliced with copper or plastic in several spots
- Leaks near threaded fittings, where galvanized pipe tends to thin first
Timing the work
Crawl space work goes more smoothly outside the coldest weeks, and planning ahead lets you schedule around holidays or travel instead of reacting to a burst line. In a historic district house, ask the plumber how openings in plaster walls will be handled before work starts. Lexington takes plumbing permit applications through its online Permit Portal, and the plumber usually files it.
