Trenchless sewer contractors serving Burbank: what to ask before you sign

What "trenchless" promises and what it does not

A trenchless contractor repairs or replaces a sewer line from inside it or along its existing path, so the yard, driveway and street above stay intact. For a property in Burbank that usually means one of three things: a cured-in-place liner cured inside the old pipe, a new pipe pulled through while a bursting head splits the old one, or a short sleeve set over a single bad joint. What it does not promise is that no hole is ever dug. Bursting needs two small pits, and a line with no cleanout may need one opened. A contractor who says there will be no digging at all before anyone has seen the pipe is guessing.

Six questions worth asking before the camera visit

• Who owns the lining equipment and who operates it, a staff crew or a subcontractor?
• Will I receive the full inspection recording, not a clip, before any proposal is written?
• What resin and liner system do you use, and is it rated for the pipe diameter in my house?
• How are branch connections reopened after a liner cures, and is that included?
• Which permits does this job need in Burbank and who files them?
• What exactly does the warranty cover, for how long, and is it in writing?

The answers matter less than how readily they come. A contractor who does this work every week in Los Angeles County answers them in a minute. Service areas and crew details for TSR Trenchless, Inc. are on the TSR Trenchless, Inc. service area page for Burbank.

How a trenchless quote is actually built

Trenchless pricing is not a flat rate per house. The drivers are the length of pipe from the cleanout to the city main, the diameter, how many branch lines join it, how deep it sits where the pits go, what the cleaning turns up, and whether the connection at the main is included. Access adds cost when the only cleanout is under a bathroom floor or the lateral runs beneath a pool deck. Permits and traffic control add a line when any part of the work is in the public way. A proposal that lists these items separately lets you see where the money goes; a single lump sum hides whether the final video and branch reinstatement are included or will appear later as extras.

Licenses, insurance and the CIPP verification mark

Three documents belong in your hand before work starts: the state license number with its classification, a certificate of general liability insurance naming your address, and proof of workers compensation for the crew. Beyond the paperwork, the trade has started to police itself. The directory at the cured-in-place pipe industry reference lists lining contractors that have documented their training, equipment and completed installations, and the TSR Trenchless, Inc. entry there shows what that verification involved. It is not a government stamp, but it separates contractors who install liners routinely from those who sell them and hand the work to someone else.

Scheduling a job in Los Angeles County

Expect three visits: the inspection, the repair day, and sometimes a short return for a connection at the main once the permit clears. On the repair day the crew needs truck access near the cleanout, which in parts of Burbank means reserving curb space the night before, and the drains stay out of use for the hours the foreman names. Water is not shut off. Residential liners are usually cured and back in service the same evening; bursting runs a long day. Rain pushes resin work, so a winter schedule carries a weather clause.

Red flags that end the conversation

A few things should stop a homeowner in Burbank from signing. A price given before any camera has been in the pipe. Pressure to decide tonight because the crew "happens to be in the area." A refusal to hand over the full inspection recording. A warranty described verbally but not written into the proposal. A license number that does not match the company name on the truck. None of these means the work would be bad, but each removes the owner's ability to check, and trenchless work is checked almost entirely through paperwork and video because the pipe is underground.

The warranty and the file you keep

When the job is done you should hold the pre-repair video, the post-repair video, the permit and inspection sign-off, the resin and liner data sheets, and a written warranty that names the property and the pipe run it covers. Together they are the record a buyer, an insurer or a future plumber will ask for.
