Many Jacksonville homes built before the mid-1970s still have their original cast iron drain lines. As they age, they corrode from the inside and start to fail. Common warning signs include:
We inspect the line, show you what we find and replace failing cast iron with modern PVC drain pipe that resists corrosion and restores reliable drainage.
What homeowners with older plumbing ask us most.
Cast iron drains can last for decades, but in Florida many lines in homes built before the mid-1970s are now showing corrosion, cracking and channeling. Age, water chemistry and soil conditions all affect lifespan.
Repeat clogs, slow drains, sewer smells, leaks and backups are common signs. An inspection confirms the condition of the pipe before you decide on repair or replacement.
Sometimes. If damage is limited to one section, a partial replacement may make sense. When the whole line is deteriorating, full replacement is usually more cost effective over time.
We typically replace cast iron drain lines with PVC, which does not rust, has smooth walls that resist clogs and meets current plumbing code.
It depends on where the pipes run. We plan the work to limit disruption, explain exactly which areas need to be opened and keep your home as clean as possible during the job.
