Frequently Asked Questions

Common questions about cast iron pipe replacement

Homes built before 1975 in South Florida typically have cast iron drain pipes. You can check exposed pipes in your garage, under sinks, or in the attic. Cast iron is dark gray/black and you may see rust or corrosion. We offer free video inspections to assess your pipes.
Cast iron pipes typically last 50-75 years. However, Florida's humid climate and soil conditions can cause faster deterioration. If your home is 40+ years old with original plumbing, it's worth getting an inspection.
Cast iron fails due to internal corrosion from waste and external corrosion from soil moisture. South Florida's high humidity and acidic soil accelerate this process. Signs include rust flakes in drains, slow drainage, and sewage odors.
Costs range from $4,000-$15,000+ depending on pipe length, location, and method. Under-slab replacements cost more due to concrete work. We provide free estimates after video inspection so you know exact costs upfront.
Minor issues can sometimes be repaired, but significant corrosion or multiple problem areas usually make replacement more cost-effective. We'll honestly assess whether repair or replacement makes sense for your situation.
Trenchless pipe lining inserts an epoxy-coated liner into your existing pipes, creating a new pipe inside the old one. This works for pipes with minor corrosion but requires the pipe to maintain its shape. It's faster and less disruptive than excavation.
Traditional replacement typically takes 2-5 days depending on scope. Trenchless lining can often be completed in 1-2 days. Under-slab work may take longer due to concrete removal and restoration.
Yes, Florida building codes require permits for drain pipe replacement. Hernandez Plumbing handles all permit applications and inspections as part of our service.
Depending on project scope, you may be able to stay. When the project involves demolition of the majority of your home, it might be difficult to remain home while work is ongoing. We'll discuss this during your consultation.
