What causes older cast-iron drain lines to fail?

Cast iron typically corrodes from the inside out over decades. As rust and mineral scale accumulate along the pipe walls, the metal thins and hairline stress fractures develop, leading to leaks behind finished walls or inside crawlspaces.

Why are clogged or broken downspout lines dangerous for a house?

Downspout lines handle thousands of gallons of roof runoff during heavy storms. When the underground pipe is crushed, separated, or clogged, water overflows next to the foundation, increasing hydrostatic pressure and leading to basement leaks or cracked walls.

Can you tie modern PVC drain pipe directly into existing cast iron?

Yes. Using code-approved shielded transition couplings with stainless steel bands, we securely mate rigid PVC pipe to older cast-iron stacks to create a leak-proof, structurally supported junction.

Repair & Replacement

What We Handle

Drain repair fixes structural failures in your home's wastewater plumbing. In older Cincinnati homes, aging cast-iron drain stacks crack along vertical seams or corrode at the base fittings. We cut out damaged cast-iron sections and tie in smooth-walled PVC using heavy-duty shielded mechanical couplings engineered to maintain structural alignment. For exterior downspout drainage lines, broken corrugated pipe dumping roof runoff next to basement walls is excavated and replaced with rigid, smooth-wall PVC piping with proper slope to carry stormwater safely away.
