Clearing the immediate backup
Getting the property usable again, which is a separate step from fixing whatever caused the blockage in the first place.
When every drain in the house slows down together, the problem is usually past the fixtures and out in the main line. Plano 24 Hour Plumber inspects the line, shows you what is wrong with it and explains what repairing it involves.
While you wait, stop running water anywhere in the property, including the dishwasher and washing machine, because everything you send down has to go somewhere. Keep people and pets away from any sewage that has come up, and do not try to clear a main line yourself.

The inspection comes first, because sewer work is expensive to do twice. Plano 24 Hour Plumber shows you the evidence before recommending a repair.

Running a camera down the line shows roots, breaks, bellies holding water and scale, with the location and depth noted.
Marking where the damaged section sits in relation to the house, the driveway and the trees, which decides how it can be reached.
Cutting roots restores flow, but the joint they came through is still open. You are told what that means for the next few years.
Replacing the failed length rather than the whole run where the rest of the pipe is sound, with the reasoning explained.
Cast-iron and clay lines in older neighborhoods behave differently from modern plastic, and that changes what is realistic to repair.
Clearing a line and repairing a line are two different purchases. Clearing gets the house working tonight. Repairing addresses the reason it stopped working. If the camera shows roots at one joint, or a single cracked section, replacing that part is usually the proportionate answer. If it shows a line that has sagged in several places or a cast-iron run that has corroded along its length, repeated clearing just postpones the same conversation.
Older parts of Plano and neighboring towns still have plenty of cast-iron and clay sewer lines, and the big mature trees that make those streets pleasant are the same trees whose roots find a joint and grow into it. Newer subdivisions have plastic lines instead, where the more common issues are settlement and construction damage. Compare the symptoms in our guide on a clogged drain versus a sewer line problem, or start with drain cleaning if only one fixture is affected.

It is driven by how long the damaged section is, how deep the line runs and what is above it. A repair under a lawn is not the same as one under a driveway. Plano 24 Hour Plumber inspects with a camera first so the quote is based on what is actually down there rather than an assumption.
Roots do not usually break a sound pipe. They find an existing gap at a joint or a crack, follow the moisture in and then grow. That is why root problems cluster in older neighborhoods with old pipe joints and large trees. Cutting them clears the flow; closing the way in is the actual repair.
Treat it as one. Stop using water in the property, keep people and pets out of the affected rooms and call Plano 24 Hour Plumber at any hour. Sewage is a health risk, not just a mess, and cleaning it up before the line is cleared usually means doing it twice.
In most cases the property owner is responsible for the sewer lateral running from the house to the city main, while the city looks after the main itself. That is the general pattern rather than a rule for every property, so it is worth confirming with the city for your address. Plano 24 Hour Plumber can tell you where the problem sits on that line.
Tell us which drains are affected and whether anything has come up inside the property.
