Cast Iron Pipe Replacement in Carrollton, TX
Almost three-quarters of Carrollton's homes were built in the 1970s, and many of them still drain through cast iron. When drains keep backing up or the camera shows scale, cracks, or separated joints, we replace the failing pipe with PVC and put the whole plan in writing first.
A 1970s Housing Boom Means a Lot of Aging Cast Iron
Carrollton went from a small town to a big suburb in a single decade. The population roughly tripled between 1970 and 1980, and most of the city's housing was built during that stretch. Homes from that era commonly have cast iron drain lines, and after about fifty years many of them are heavily scaled or cracking.
The southern and central parts of the city, closer to the historic Square and Josey Ranch, sit on expansive Blackland Prairie clay. That soil moves with wet and dry seasons and puts steady stress on the joints of drain lines under slab foundations.
Every job starts with a camera inspection so you can see what is going on inside the pipe. When only one section has failed, we fix that section. When the cast iron is worn out end to end, we replace it with PVC and test the new line before we close anything up.
Signs Your Carrollton Home's Cast Iron Drains Are Wearing Out
One of these is worth a camera look. Several together usually mean the cast iron itself is wearing out.
Scale inside old cast iron catches grease and debris. If a drain keeps backing up after it has been cleared, the pipe is often the cause.
Slow drains throughout the house usually point to the main drain or sewer line rather than a single fixture.
Cracked pipe and loose joints let sewer gas out. Smells near floor drains, cabinets, or the yard are a common early sign.
A leaking drain under the slab can wash out soil, leading to damp spots, odors, or new cracks near bathrooms and the kitchen.
Neighborhoods like Woodlake, Rosemeade, High Country, and Carillon Hills were built in the age range where cast iron drains are common.
Roots find their way into cracked cast iron and clay joints. A wet or extra-green strip in the yard can trace a leaking line.

We swap the cast iron for PVC, test the new line, and run the camera again so you can see the finished work.
Where We Find Cast Iron Drains in Carrollton
Build era is the best early clue to what's under the slab.
Some homes near the Square date to the early 1900s. Older homes here may have cast iron or clay drains, sometimes mixed with sections replaced over the years.
Built in the 1960s and 1970s, Woodlake is one of the north Carrollton neighborhoods where original cast iron drain lines are most likely.
Most homes here went up from the late 1970s through the 1980s. That timing straddles the move from cast iron to plastic drains, so a camera check tells us which one you have.
Homes near Josey Ranch Lake Park date to the early 1980s and sit on the clay-heavy south side of the city, where soil movement adds stress to older drain joints.
