Trenchless Sewer Replacement

Trenchless Repair Methods

Sewer line replacement doesn't mean destroyed yards, ruined driveways or devastated parking lots. Comet’s trenchless sewer line repair causes less damage than traditional repair methods. Trenchless repair is our next step in quality sewer maintenance with less environmental impact.


Pipe Bursting

We make small access holes where the damaged pipe starts and ends. Using your broken sewer line as a guide, our hydraulic machine pulls full-sized replacement pipe through the old path and breaks up the damaged pipe at the same time. The new pipe is highly resistant to leaks and root intrusion, with a long life expectancy.




Reasons to consider trenchless sewer repair:


You will save money

One of the major reasons people call for trenchless sewer repair is the money-saving aspect of it. Trenchless sewer repair means more money in your pocket than traditional sewer excavation. You get the same quality of repair as you would with an excavation, but at a fraction of the cost.


You will save time

Most trenchless sewer repair jobs can be completed within one to three days. That means your life will not be placed on hold for weeks while a crew digs up your entire yard. Trenchless sewer repair will get you back to living normal life much faster.


You will spare your landscaping  

Since there is no digging associated with trenchless sewer repair, your landscaping will not be harmed. This will not only save you a major mess, but also a ton of money.


It's a sustainable solution

Common methods of trenchless sewer repair, such as pipe-lining and pipe bursting, are highly durable and last for decades, eliminating the potential for an additional repair in the near future.


Better functionality after repair  

In addition to durability, trenchless pipe repair and replacement uses seamless technology, which can actually improve your sewer system's function by flow capacity.



If you are experiencing any of these common sewer problems, or any other sewer-related issues at your home, call on the experts at Comet Plumbing & Sewer Co. to access the situation and determine if trenchless sewer repair is the right option for you.

Los Altos plumber. ★★★★★
I found this company in my Los Altos Yellow Pages. They checked out my hot water heater which was very noisy and recommended we change it. I never thought about buying a larger capacity water heater for our home until the plumber had mentioned it. So not only do I have a new heater but also more hot water. Now the family will be happy :)

My family and 
I just moved in, my mother was alarmed when the kitchen sink wasn't draining properly. The owner of Comet Plumbing came quickly to check the plumbing under the sink which I knew was old.

Andrew unblocked the clog and installed new pipework beneath the sink. I am very grateful,it was only $99.00 for this great service.
