Day one: the call
The first conversation establishes three things: the address in Agoura Hills, what is happening at the fixtures, and whether anything is backing up right now. If it is, the visit is dispatched for the same day and the cleaning comes first. If it is not, an inspection is booked at a time that suits the household. Nobody quotes a repair on this call, and you should be suspicious of anyone who does. The TSR Trenchless, Inc. area page for Agoura Hills at the TSR Trenchless, Inc. trenchless repair page for Agoura Hills shows which neighborhoods are served from which yard.
Day two: cleaning and the camera
The crew locates the cleanout, jets the line if the camera cannot see the pipe wall, and records the full run from the house to the city main. A locator on the surface marks the depth and position of each defect. You watch the recording on site and keep a copy. The written finding that follows names the pipe material, the length, the defects by distance from the cleanout, and the method the contractor recommends with the reason for it. If the pipe turns out to be sound, the visit ends there and the record is yours for the future.
The proposal and the questions to ask of it
A complete proposal itemizes the cleaning, the liner or new pipe, each branch reinstatement, the connection at the main if included, permits, traffic control if any, the final video and the warranty term. It names the liner system and resin. It states what happens if the pipe is found to be worse than the recording showed once the work starts, which is rare after a thorough cleaning but not impossible. Compare proposals line by line and ask about anything one includes that another leaves out. What a lining specification should contain is set out plainly at the cured-in-place pipe reference site.
Permits and the waiting week
Private-side work in Agoura Hills may proceed on a plumbing permit pulled over the counter or online. Anything reaching the sidewalk, the street or the connection to the main needs an encroachment permit from the city, or from Los Angeles County Public Works in unincorporated areas, and that can take a few days to two weeks. The contractor files it. If the schedule allows, the private-side liner is installed first and the connection follows when the permit clears.
Between the proposal and the permit: your part
The owner's tasks in that waiting week are small but they keep the schedule. Sign the proposal and return it, because the permit application names the contractor and the property. Confirm where the crew may park and which gate they may use. Tell a shared-lateral neighbor or an HOA what is happening and when. If the house in Agoura Hills is in escrow, send the recording and the proposal to the other party so the repair terms are agreed before the crew is booked. And ask any remaining question now; changes on the morning of the work are what push a one-day job into two.
Repair day
The crew arrives early, confirms the drains are idle, cleans the line again and measures it. For a liner, the tube is saturated with resin, installed through the cleanout, inflated and cured with hot water, steam or ultraviolet light, then the branch openings are cut back from inside with a robotic cutter. For bursting, two pits are opened, the new pipe is pulled through as the old one is split, and the ends are connected. Either way the camera runs again before the drains are released, and most houses are back in service the same evening.
Closing out
You receive the post-repair video, the permit sign-off, the material data sheets and the warranty. Keep them with the deed; a buyer's inspector will ask for them years from now. The county-wide service area and the city landers for the rest of Los Angeles County are on the Los Angeles County coverage hub.

Questions we hear about trenchless sewer repair
How long does the whole process take?+
From the first call to a finished liner, typically one to two weeks for a house in Agoura Hills, most of it waiting on the proposal review and, where needed, the permit. The on-site work is one inspection visit and one repair day. Emergencies compress that; a backup is cleared the same day and the permanent repair follows.
Why not quote over the phone from my description?+
Because the price depends on length, depth, diameter, the number of branches and the condition of the pipe, none of which a description gives. A phone quote is either padded to cover the unknowns or revised upward on the day. The camera removes the guessing.
What can delay the schedule?+
A permit for work in the street, rain when resin work is planned, a cleanout that has to be installed first, or a pipe so collapsed that the method has to change from lining to bursting after the cleaning. Each is explained before it happens, not after.
Do I need to be present on repair day?+
Someone should be reachable by phone and able to let the crew reach the cleanout, but you do not need to watch. You will be shown the post-repair video and walked through the paperwork when the drains are returned to service.
How do I start the process?+
