When your old sewer lateral is too broken to line, pipe bursting replaces it through two small pits instead of a trench across the yard.

Pipe bursting replaces a failed sewer lateral by pulling a cone-shaped bursting head through the old pipe, fracturing it outward while new seamless HDPE pipe follows right behind. It needs two small access pits, not a full trench. In Mar Vista, it's often the right call for original clay laterals that roots and age have broken into pieces.
Pipe bursting is a trenchless replacement method. A bursting head is pulled through the existing sewer line by cable or rods, and as it moves it cracks the old clay, cast iron, or fiber pipe and pushes the fragments into the surrounding soil. The new pipe is attached to the back of the head, so it's in place the moment the head reaches the far pit. This page is part of our complete guide to trenchless sewer repair in Mar Vista.
Pipe Bursting: Pipe bursting is a trenchless sewer replacement method that fractures the old pipe in place while pulling a new, continuous HDPE pipe into the same path through two small access pits.
Because the old pipe is destroyed rather than reused, bursting works where lining can't: collapsed sections, badly offset joints, and pipe that has lost its round shape. The trade-off is that it needs room for two pits and a clear path, so we check nearby gas, water, and electrical lines first.
In Mar Vista, it's often the right call for original clay laterals that roots and age have broken into pieces. Mar Vista's 1920s–1950s clay laterals are frequently too cracked and offset to line, which is where bursting shines.
We video the line, mark its route and depth, and confirm bursting is the right method for the damage we see.
A launch pit near the house or cleanout and a receiving pit near the property line or main, sized for the equipment.
The head splits the old pipe while fused HDPE follows behind in one continuous pull.
We connect both ends, run a final camera pass, pass inspection, then backfill and restore the pits.
Camera first, always. Every recommendation starts with a recorded inspection you can watch yourself, and a flat-rate price you approve before we start.
In Mar Vista we burst a lot of original clay laterals. By the time a homeowner calls us, roots have usually opened the joints, and several sections have shifted or cracked through, so there isn't enough intact pipe to hold a liner. Bursting sidesteps that. We typically set the launch pit near the house cleanout and the receiving pit near the property line, pull new HDPE through the old route, and leave the front yard, the driveway, and the parkway tree largely alone. On the smaller Mar Vista lots, careful pit placement matters more than equipment size.
Most Mar Vista homes went up between the 1920s and the 1950s, and a lot of them still drain through the sewer lateral they were built with. Mature street trees, ficus especially, send roots toward the moisture at every clay joint. We start with a camera so you can see the line yourself before anyone talks about price.

Mar Vista is inside the City of Los Angeles, so sewer work on private property is permitted and inspected through LADBS. LA Sanitation splits the lateral into an upper section, from the house to the property line, and a lower section, from the property line to the main, and the owner is responsible for maintaining both. We pull the permits and schedule the inspection, so you don't have to deal with the paperwork.
Example scenario below is illustrative, based on common situations we see. Details vary by property; not a specific customer.
A 1940s Mar Vista bungalow backs up twice in one winter, and the camera shows three cracked, root-packed clay joints plus a partly collapsed section under the lawn.
We burst the full lateral from the house cleanout to the property line, pulling in new fused HDPE with two small pits.
The line runs full-bore again, the lawn is patched in two spots instead of trenched, and the homeowner has a permitted, jointless lateral on file.
New Pro Plumbing is family-owned and led by Miguel Lopez, and many Mar Vista customers ask for him by name. We price by the job, not the hour, so the flat rate you approve is the amount you pay. And when we leave, we leave no trace behind.

The Bottom Line
If your lateral is too far gone to line, pipe bursting gives you a new, jointless pipe along the same route without trenching the whole yard. We confirm it with the camera first and quote it flat-rate.
No. Lining installs a resin liner inside the old pipe and relies on that pipe keeping its shape. Pipe bursting destroys the old pipe and pulls a completely new HDPE pipe into its place. Bursting is usually the choice when the old line is collapsed, crushed, or too misshapen to line. Bursting fractures and replaces; lining coats the inside of an existing pipe and cures. Different jobs for different pipe conditions, and one lateral sometimes needs both. Our pipe bursting overview walks through the full method.
They’re sized to fit the equipment and the connection points, typically a few feet across, one at each end of the run. That’s far less digging than an open trench along the full length of the line, and we restore the pits when the work is done. Both pits are typically three to four feet across, sized for the bursting head and the pulling rig, not the full length of the pipe. We stake locations before you approve so you know exactly where they will land in your yard or parkway.
We install high-density polyethylene (HDPE) pipe with heat-fused joints. Fused joints make the new line continuous, so there are no gaps for roots or groundwater to get into. HDPE is heat-fused rather than joined at rings, so there are no interior joints inside your yard for roots to find. Manufacturers rate the material well past 50 years underground, which is why it is a common choice for full replacement.
It can if another line sits very close to the sewer, which is why we locate the sewer and mark other utilities before we start. If the clearance isn’t there, we’ll recommend a different method rather than take the risk. Every job starts with a USA DigAlert ticket, and any utility within the bursting corridor is located and marked. You can verify our contractor license anytime at the CSLB portal.
It’s one of the methods we use most here, because so many Mar Vista homes still have original clay laterals that are too broken to line. The camera decides, though; if lining or a spot repair fits your line, we’ll recommend that instead. For Mar Vista lots with mature street trees, bursting reaches under the parkway to the connection at the public main without touching the tree. See Mar Vista trenchless hub.
