Residential Cast Iron Sewer Pipe Replacement in Addison, TX
Professional Underground Pipe Replacement for Addison Homeowners
Many homes in Addison — particularly those built before 1986 in ZIP code 75001 — still have cast iron sewer pipes running underneath the slab foundation. These aging systems may not be visible, but over time, they corrode, crack, and shift — leading to slow drains, sewer odors, and plumbing backups.
At In-House Plumbing Company, we don’t offer general plumbing or patch jobs. We specialize exclusively in cast iron pipe replacement, providing complete underground pipe replacement services that restore your home’s plumbing system from the ground up using high-quality PVC piping.
Why Cast Iron Pipes Fail in Addison
Addison homes, like others in North Texas, sit on soil that shifts as moisture levels change. That soil movement, combined with decades of wear and corrosion, causes common issues such as:
- Rusted pipe walls that restrict water flow
- Cracks and openings that allow in roots and groundwater
- Separated or misaligned joints under the slab
These issues aren’t fixable with spot repairs. That’s why we offer full pipe replacement services designed for long-term reliability.
