Cast iron drain lines scaling and cracking
Why it happens here
Homes built before 1980 in Riverside Park and Paces Ferry still run cast iron drains. Decades of water and soil movement cause the pipe to scale inside and crack at the joints. Tree roots find those cracks and grow in.
Our approach
We camera the line before recommending a fix. If the damage is isolated, we replace that section with PVC. If the whole line is failing, we quote a full replacement and explain the lifespan difference.
