Stopping the water
The first job is isolating the leak, whether that is a fixture valve, a branch line or the main shutoff at the meter box by the curb. Nothing is cut until the flow is stopped.
A split pipe can put water through drywall, insulation and flooring in minutes. Shut the water off at the meter, keep clear of anything electrical, and an independent plumber can assess the break and repair options.
February 2021 showed what a hard freeze does to North Texas plumbing: attic and exterior-wall lines in Carrollton houses split as they thawed, often days after the power came back. Pipes in unheated attics, in garages and at outdoor spigots are still the first places to fail.

Not every problem needs all of this. Ask the independent provider which work is needed and which is optional.

Water travels along joists and inside walls, so the wet patch is rarely above the split. The line is traced so the smallest possible area is opened.
The damaged section is replaced with pipe suited to the rest of the system, then the line is pressurized and checked before the wall or ceiling is closed.
Some breaks are a single coupling. Others show a run of pipe that has been corroding for years, in which case replacing the whole section is the repair that actually holds. You are told which of the two you have before any work starts.
If the break is under the floor rather than in a wall, see slab leak repair. If the pipe is intact but water is still going missing, leak detection is the place to start, and the repair versus replacement guide covers the same decision for a leaking heater.
Repairs are arranged across Carrollton and nearby, including Farmers Branch. Not sure if you are covered? Check the service areas.
Close the main shutoff, which in most Carrollton homes is in a meter box near the curb, and open a low tap to drain the pipes. Stay away from water near outlets, panels or light fittings, and move what you can off wet flooring.
The pipe material, where the break is and how much has to be opened to reach it. A split under a sink is not the same job as a line inside a ceiling. Ask the independent provider for a quote after the break has been assessed.
Same-day repair is not guaranteed. Access, pipe condition, permits and provider availability affect timing. Confirm the schedule with the independent provider.
Age and water chemistry. Galvanized supply lines in older Carrollton neighborhoods rust from the inside until the wall gives out, and high pressure accelerates it. A pressure and line check shows whether more of the system is at risk.
