Cast Iron Pipe Replacement in Lewisville, TX
From Old Town to the 1970s neighborhoods near Stemmons Freeway, many Lewisville homes still drain through cast iron. When drains keep backing up or the camera shows scale and cracks, we replace the failing pipe with PVC, and our shop is only 10 to 15 minutes away.
Older Lewisville Homes, Older Drain Lines
Most of Lewisville's homes were built between the 1960s and the 1990s, and the city's Old Town core goes back even further. Homes from the earlier part of that range commonly have cast iron drain lines, and decades of corrosion leave them scaled, thin along the bottom, or cracked at the joints.
Many of the city's older sections sit on expansive clay that swells and shrinks with the seasons. That movement works on drain lines under the slab and in the yard, which is how a pipe that is already weak ends up cracked or separated at a joint.
We start with a camera inspection so you can see the inside of the pipe for yourself. One bad section gets a section repair. A line that is worn out end to end gets replaced with PVC, tested, and checked again on camera before we close anything up.
Signs the Cast Iron in Your Lewisville Home Needs Attention
One of these is worth a camera look. Several together usually mean the cast iron itself is wearing out.
Scale inside cast iron catches grease and paper. If the same drain backs up again soon after cleaning, the pipe is often the cause.
When multiple fixtures slow down at the same time, the main drain or sewer line is usually involved.
Cracked cast iron and loose joints release sewer gas. Smells near floor drains, vanities, or outside are worth a camera inspection.
A leaking drain under the slab can wash out the soil beneath it, leading to damp flooring, odors, or new cracks near bathrooms.
Old Town and the city's 1960s and 1970s neighborhoods are where original cast iron drain lines are most common.
Roots work into cracked pipe and old joints. A soggy or extra-green strip in the yard often follows the line.
Look Inside the Pipe Before Anyone Picks Up a Shovel
Nobody gets a price over the phone. We inspect first, then match the fix to what the pipe shows us.
- 1Run a camera through the line
We camera the drain from a cleanout and record the footage. Watch with us and keep a copy.
- 2Locate the damage
A locator in the camera head shows exactly where the bad sections are and how deep they sit.
- 3Put the plan and price on paper
You get a written plan covering what gets replaced, where we need access, the new pipe material, and the cleanup involved.
- 4Pull the City of Lewisville permit
Lewisville's Building Services division issues permits for sewer repair work. We pull the permit and schedule the inspection.
- 5Replace, test, and camera again
We replace the cast iron with PVC, test the new line, and run the camera once more so you can see the finished work.
Where We See Cast Iron Drains in Lewisville
Some parts of the city are far more likely to have cast iron than others.
The homes around Mill Street and Main Street date from the early 1900s through the 1940s. Many have been updated over the years, so we often find old cast iron tied into newer sections.
These ranch-style neighborhoods near Stemmons Freeway were built mostly from the 1970s on, the era when cast iron drain lines were still common in slab homes.
These older neighborhoods near Lewisville Lake are the kind of established housing where original drain lines are reaching the end of their life.
Homes here were mostly built from the mid-1990s on, so plastic drain lines are typical. Calls here are usually a damaged section rather than worn-out cast iron.
