Repiping a St. Petersburg home starts with knowing what is in the walls. Here is a plain guide to pipe types, costs and permits, plus a free, no-obligation estimate.
About St. Petersburg
St. Petersburg is the largest city in Pinellas County, with 258,308 residents at the 2020 census. It was founded in 1888 and grew in big waves: a 1920s boom that nearly tripled the population, postwar growth from about 97,000 people in 1950 to 181,000 in 1960, and more growth through the 1970s.

Neighborhoods such as Old Northeast and Snell Isle have Mediterranean Revival homes, and the Grand Central District has Craftsman houses. Add the huge stock of 1950s and 1960s homes, and St. Pete has every pipe era, from galvanized and cast iron to polybutylene.
What's likely in the walls of St. Petersburg homes
The year a home was built is the best first clue to its plumbing. These are general patterns, not a diagnosis. Remodels and past repairs change what is there, and a licensed plumber confirms it on site.
- Homes built before about 1960 often started with galvanized steel water lines and cast iron drains. Many have been partly updated, so a mix of materials is common.
- Homes from the 1950s to mid-1970s commonly have copper or galvanized supply lines and cast iron drains under the slab.
- Homes built from about 1978 to 1995 may have polybutylene, the gray plastic supply pipe that many Florida insurers will not cover.
