CIPP sewer repair - cured-in-place pipe lining - repairs a damaged sewer line by installing a resin liner inside the existing pipe without digging a trench. The pipe has to qualify. The camera inspection determines whether it does.
What you are seeing
The sewer line has damage - cracks, joint deterioration, root intrusion, minor offsets - but the pipe is still structurally intact enough to hold its shape. You have been told trenchless repair might be an option, or you have come across the term CIPP while researching alternatives to digging up the yard. Now you want to know what the method actually involves and whether your line qualifies.
CIPP - cured-in-place pipe - is a specific trenchless rehabilitation method. It is not a brand name or a general term for no-dig repair. It describes a process where a resin-saturated liner is inserted into the existing pipe and cured in place to form a new pipe wall inside the old one.
When this method applies
CIPP sewer pipe lining applies when the existing pipe has cracks, joint separation, root entry points, or minor infiltration - but the pipe walls are still intact enough to serve as a host for the liner. The liner bonds to the inside of the existing pipe and becomes the new structural wall.
Lines that are fully collapsed, severely deformed, back-bellied, or have lost too much of their original diameter do not qualify. The host pipe has to maintain enough shape and alignment for the liner to seat properly and cure to specification.
What you walk away with
You walk away with a continuous, jointless liner inside your existing sewer pipe - sealing cracks, bridging joint separations, and blocking root entry points from the inside. No trench across the yard. No driveway removal. No landscape demolition. The camera documents the completed liner from end to end, and the surface above the pipe stays intact.
Problem
The sewer line needs more than cleaning. The camera shows cracks, separated joints, or root intrusion that will keep coming back. But the pipe is not collapsed. It is not deformed beyond use. It is damaged in ways that a structural liner can seal from the inside - if the pipe qualifies for the method.
CIPP stands for cured-in-place pipe. The method works by inserting a flexible, resin-saturated felt or fiberglass liner into the existing sewer pipe through an access point - usually the cleanout. The liner is positioned inside the damaged section, then inflated against the pipe walls and cured using heat, UV light, or ambient temperature depending on the resin system. As the resin cures, the liner hardens into a rigid structural tube bonded to the inside of the host pipe. The result is a new pipe wall - jointless, seamless, and resistant to root intrusion - formed inside the old one. The appeal is obvious: no trench, no excavation, no surface demolition. For homeowners with sewer lines running under driveways, patios, landscaping, or mature trees, CIPP can eliminate thousands of dollars in surface restoration costs that conventional replacement would require. The repair happens entirely from the inside of the pipe. But CIPP is not universally applicable. The existing pipe has to be a viable host. It needs to be round enough for the liner to inflate against the walls uniformly. It cannot have sections that are collapsed, crushed, or so deformed that the liner would cure in an irregular shape. It cannot have significant bellies where the liner would bridge a low point instead of bonding to the pipe wall. And severe offsets at joints - where one section of pipe has shifted significantly out of alignment with the next - can prevent the liner from seating properly at the transition. The camera inspection answers every one of these qualification questions before the method is committed to.
Solution
CIPP sewer repair starts with a camera inspection after jetting. The camera documents the pipe's internal condition - diameter, roundness, wall condition, joint alignment, and the specific type and location of every defect. That footage is what determines whether the pipe is a CIPP candidate or whether a different repair method is needed.
If the pipe qualifies, the liner is prepared to match the pipe's diameter and the length of the section being rehabilitated. The resin-saturated liner is inserted through the cleanout or an access point, positioned within the damaged section, inflated against the pipe walls, and cured. Once cured, the liner is a rigid structural tube that seals every crack, joint gap, and root entry point it covers. The result is a continuous, jointless pipe wall inside the existing host - with no excavation above.
After the liner is cured, the camera runs the rehabilitated section again to verify that the liner seated properly, cured uniformly, and achieved full coverage of the damaged area. That post-lining footage is the verification that the repair is sound - and the property owner sees it before the crew leaves.

Leave a Review!Amazing experience! They are knowledgeable, kind, courteous and very thorough. Our clogged kitchen pipe was a bit of a challenge but they kept going and did everything they could to get it unclogged and they did it! They were very upfront with what caused the clog, gave us video recording of our pipes so we can see exactly what was done, double checked to make sure the pipes were clean and free of clogs and gave us steps on how to maintain the pipes moving forward. Highly recommend!!
I had an Emergency pipe back up AJ and Jake came snaked and got it all jetted out and cleaned up quick and for a really fair price! Anyone in need I would highly recommend
Very professional, quick and efficient work definitely would recommend
Highly recommend, very quick and easy to work with crew, drain cleaned my main sewer line professionally and well done.
This company is Awesome!!! Highly recommend that you call them for your drain cleaning and power washing needs! A++ in service, cost, and quality of work. Alex and Jacob completed drain work, patio cleaning, and filled in cracks in cement. The patio looks brand new! Thank you Alex and Jacob!!!
Alex was very good to work with. They were professional and punctual, working around my schedule. They were able to show me exactly before and after, even showing footage inside my pipes, which I have never seen before. I would recommend them.
Why Mountain West
Camera rated to 200 feet
Documents the full sewer line to assess CIPP candidacy - pipe roundness, wall condition, joint alignment, and every defect that affects liner viability. Post-lining camera pass verifies the liner seated and cured properly from end to end.
Jetting and camera on every call
Hydro jetting equipment deploys on every service call. The line must be clean before the camera can accurately assess CIPP qualification - debris, roots, or buildup can mask the true pipe condition underneath. Jetting and camera happen in the same visit.
3,850 PSI jetting capability
Clears lines 2 to 12 inches in diameter at 3,850 PSI and 8 GPM with 300 feet of reach. Thorough cleaning before the camera pass is critical for CIPP assessment - the camera needs to see clean pipe walls, not residue from the last backup.
20+ years combined field experience
Two decades of evaluating sewer lines for trenchless viability - the judgment to know when CIPP is the right method, when pipe bursting is the better fit, and when the line has crossed into conventional replacement territory regardless of what the homeowner prefers.
Licensed and insured
Licensed for sewer, drain, and drainage system work covering the full scope of trenchless rehabilitation as well as conventional excavation and replacement if CIPP does not fit.
A CIPP repair follows a specific sequence: clean the line, camera-assess for lining viability, install the liner, cure it, and verify the result on camera.
You leave the visit knowing whether CIPP was viable and, if it was, with a camera-verified structural liner inside the pipe, no trench in the yard, and documented proof that the repair sealed every defect the lining covered.
CIPP is one trenchless method. Not every pipe qualifies for it, and not every sewer problem is best served by lining. If the line does not meet CIPP criteria, or if the damage calls for a different approach, these services cover the alternatives.

CIPP sewer repair - cured-in-place pipe - is a trenchless method that repairs a damaged sewer line by inserting a resin-saturated liner into the existing pipe and curing it in place. The liner bonds to the inside of the host pipe and forms a new, jointless structural wall - sealing cracks, joint separations, and root entry points without excavation. The existing pipe must be structurally intact enough to serve as a host for the liner.
A sewer line qualifies for CIPP sewer pipe lining when the pipe is still holding its round shape, the walls are intact enough to support a bonded liner, and the defects - cracks, joint gaps, root entry points - can be sealed from the inside. Lines that are collapsed, severely deformed, back-bellied, or have major offsets at joints typically do not qualify. A sewer camera inspection after jetting determines CIPP viability based on the actual pipe condition.
The sewer line is jetted clean, then the camera assesses the pipe for lining viability. If the pipe qualifies, a resin-saturated felt or fiberglass liner is inserted through the cleanout, positioned inside the damaged section, inflated against the pipe walls, and cured using heat, UV light, or ambient methods. Once cured, the liner hardens into a rigid structural tube bonded to the host pipe. A post-lining camera pass verifies full coverage and proper cure.
CIPP sewer pipe repair cost depends on the linear footage being lined, the pipe diameter, the prep work required before lining, and whether the full run or a partial section is being rehabilitated. CIPP typically costs more per foot than conventional spot repair but eliminates excavation and surface restoration costs - which can make it the less expensive total option on lines under driveways, patios, or landscaping. Mountain West provides a scope and estimate after the camera inspection confirms CIPP viability.
