Common questions
What does drain repiping cost?
It depends on how much pipe needs replacing, whether it's under the slab or in the walls, and how we need to access it. A camera inspection shows us exactly what's damaged, and you get a firm price before any work starts.
Why do cast iron drains fail?
Cast iron corrodes from the inside over decades. Florida's water and soil conditions speed that up, leading to scale buildup, cracks and eventually holes in the pipe.
Do I have to replace all the drain pipes?
Not always. If the pipe is scaled up but still structurally sound, cast iron descaling can restore flow and extend its life. If the damage is limited to one section, a partial replacement can make sense. The camera inspection shows us which option fits.
Will insurance cover drain repiping?
Some policies cover part of the cost, such as access and repair of damage, but coverage varies. We can provide inspection footage and documentation to support your claim.
