Sewer line trenching
The dig done right, start to finish
Sewer line trenching is the excavation side of a sewer replacement: cutting a clean, safe trench to expose the failed line, so new pipe can be laid on the right grade and buried properly.
TJM has dug its own sewer lines since 2005, with our own equipment and our own crew. The plumber who plans the repair is part of the same company that digs the trench, lays the pipe, and closes the hole.

Why does it matter who digs the trench?
Because on most sewer jobs, the digging is the bottleneck. Many plumbing companies quote the repair, then wait on an excavation subcontractor's schedule before anything moves, and every day the trench waits is a day your sewer stays broken. TJM digs its own jobs as part of our excavation services in Elgin, so the machine, the pipe, and the crew arrive together. There is no gap between the dig and the plumbing, no second company to coordinate, and one name accountable for the whole hole in your yard, from the first bucket of dirt to the last.
How deep is a sewer trench, and is it safe?
Sewer trenches run deep, because the line must hold a steady fall to the main and stay below frost depth, and a deep trench is nothing to treat casually. Federal trenching and excavation safety rules exist because unprotected trench walls can collapse without warning, and OSHA treats excavation as one of the most hazardous parts of construction. This is exactly why a homeowner should never open a sewer trench themselves, and why we dig to standard on every job. Our crew has been putting machines in the ground since 2005, and the trench gets as much care as the pipe.
One crew digs it, pipes it, and closes it
No waiting on a subcontractor. Sewer digs handled start to finish by a family-owned Elgin crew since 2005.

It is the straightforward cure for a failed line. We expose the run, remove the broken clay or cast iron completely, lay new pipe on a proper grade, have the work inspected, and backfill in stages so the ground settles right. Nothing stays hidden, because the old pipe leaves the ground and the new pipe is visible before it is buried. The same open-cut approach handles our utility trenching work for water services and other buried lines, so whichever pipe fails, the crew and the equipment are the same. One trench, one company, and a line that is genuinely new.
What happens to the yard when the job is done?
Backfill is where a cheap dig shows itself a year later, when the trench line sinks into a rut across the lawn. We backfill in compacted stages, grade the surface out, and leave the site orderly before the equipment rolls away. You also get the photo record. TJM has documented every job before, during, and after since 2005, so you can see the pipe, the trench, and the finished grade even though the work ends up buried. Before we start, we walk you through exactly where the trench will run and what the yard will look like when we leave.

Straight answers to plumbing questions
How much does sewer line trenching cost in Elgin?
Depth, length, and what sits above the line set the price. We scope the job, explain exactly what the dig involves, and give you a clear written number before a shovel touches dirt.
Do you dig with your own equipment?
Yes. TJM has dug its own sewer and water lines with its own machines since 2005. The crew that digs the trench is the same crew that lays the pipe and backfills it.
How long does an open-trench sewer replacement take?
It depends on the depth and the length of the run. Because one crew handles the dig, the pipe, and the backfill, nothing sits open waiting on another contractor to show up.
Do you locate buried utilities before digging?
Always. Illinois requires a JULIE locate before any excavation, and we schedule it as part of the job. Gas, electric, and water lines get marked before our equipment touches the ground.
Is open-trench replacement the right fix for my sewer?
It removes the failed pipe completely and sets the new line on a proper grade, which is why we use it. We look at your line first and tell you honestly what it needs.
Will my yard be left a mess after the dig?
No. We backfill the trench in stages so the ground settles right, then grade it out as part of the job. You will know exactly what the yard will look like before we start.
