Three repair levels, three price bands. Clearing the roots starts at $150+ and buys time rather than a fix. Hydro jetting with root-cutting heads starts at $350+. Lining the affected section starts at $3,500+ and seals the entry points for good. A camera inspection at $250+ decides which one your line needs.
Final cost depends on inspection findings.
Four things move the number, and length matters most. A single failed joint needs a spot repair. A lateral with roots entering at three points along forty feet needs a full liner, and the cost tracks the footage.
Pipe material comes second. Cast iron that has lost wall thickness may not hold a liner, which pushes the job toward replacement. Access comes third, since a line running under a driveway or patio costs more to reach when trenchless will not work. Depth comes fourth, and North Texas laterals sit deeper than many homeowners expect.
Nobody can quote this honestly from a phone call. A camera inspection shows the pipe material, the wall thickness, where the roots entered, and how many entry points exist. Those four facts decide between clearing, lining and replacing, and the price gap between those three is large. Any contractor quoting sewer root repair without looking inside the pipe is guessing.
