Is Pipe Relining Worth It?

O’Grady Plumbing (OGP) is San Francisco’s multi-generational residential and commercial plumbing company.

Each year, many homeowners face the choice of whether to repair or replace their home’s plumbing. While there are a variety of factors to consider when making this decision, one option that is frequently debated is pipe relining. So, what exactly is pipe relining and is it worth the cost? In this blog post, we will explore these questions and help you decide if this type of plumbing repair is right for your home. 

What Is Pipe Relining?

Pipe relining is the process of repairing a damaged or collapsed sewer pipe without having to dig it up. This trenchless technology involves inserting a new pipe liner into the existing pipe. The liner is then inflated and allowed to harden, creating a new pipe within the old one. Pipe relining can be used to repair pipes that are cracked, broken, root-damaged, or offset. Without having to dig up the ground, pipe relining can be used to fix cracked or damaged pipes. In essence, it entails inserting a new, durable pipe within the already-damaged one to improve flow and repair fractures. The relined part completely seals against the remainder of your pipe system, halting leaks and averting additional breakdowns. Since there is no need for excavation, you won’t have to disturb your garden as much as you would if you were completely replacing your pipes with the pipe relining method, which is even stronger than brand-new pipes. 

There are factors to consider before deciding if pipe relining is the right solution for you 

  • The type of damage to your sewer pipe:

This is an important factor to consider, especially as not all types of damage can be fixed with pipe relining.

  • The location of the damage:

If the damage is located in an area that is difficult to access, it may be more complicated and, as a result, more expensive to fix.

  • The severity of the damage:

If the damage is too severe, you may need to replace your sewer pipe entirely instead of repairing it.

  • Cost:

Since pipe relining can be more expensive than traditional pipe repair methods, it is an important factor to be considered. You have to prepare a budget for the cost of materials, labor costs, and everything else that might come up.

  • Warranty:

Most pipe relining companies offer a warranty on their work. This is more like a guarantee given to the customers that their work is in perfect shape.

Our Installation Process

Initial Survey

In this step, we conduct a thorough examination and measurement of the pipes. The plumbing system is first inspected using a drain camera to look for any breaks or pipe obstructions and to take measurements. Our ability to pinpoint the issue’s specific nature and location is aided by this.

Custom Pipe Linings and Bladders

With the dimensions in hand, we designed a felt liner and an inflated bladder specifically to fit the pipe’s precise requirements, including any bends or junctions.


We soak the felt liner in epoxy glue when we are ready to install the relined pipe segment, and then we slide the deflated bladder into the pipe liner. Utilizing the current access points to your pipes, we utilize ropes that are fastened to the liner’s ends to pull it into position. We pull the felt liner and deflated bladder into position inside the pipe without digging by utilizing the attached ropes and the already-existing access points to your pipes. A specialized drain camera is used to line it up to ensure it is in the proper location. The felt liner is then blown out to seal against the pre-existing pipes, forming a new pipe that plugs any breaks or cracks. Next, we inflate the bladder with air to create the new pipe. The bladder is kept inflated until the resin has fully dried to form a hard, sturdy pipe. Following that, we deflate the bladder and remove it from the pipe, giving you a completely new, sturdy, and waterproof pipe.

Final Test and Survey

Checks and tests are done on the relined portion to ensure that everything is done properly. We then utilized our CCTV drain surveillance camera to make sure everything was set up and sealed properly.

Materials Used for Pipe Relining

At O’Grady Plumbing, we utilize four different types of pipe relining systems, from pressured pipe relining to sewage pipe relining, each of which is specifically designed for a particular environmental element.


Our most popular pipe relining material, Blueline, may be applied to pipes with bends and junctions and can be used to reline pipes in general. Blueline is used for residential and commercial projects to repair sewage pipes, stormwater systems, vertical drain stacks, and trade waste pipes, regardless of the material they are composed of: clay, concrete, metal, iron, steel, PVC, or fiberglass. For oil, marine, and drain pipes as well as heavy wear or impact systems, the structural relining solution, Blueline, is the best choice. Because of its inherent flexibility and high elongation, the polyester and/or polypropylene staple fiber blend in the liner enables engineers to set mechanical and hydraulic parameters that will reduce installation damage and be suitable for a variety of harsh weather conditions. A two-part epoxy glue that is abrasion- and impact-resistant is used to quickly cure the liner once it has been pushed into position using existing access ports.



Although Greenline is a structural relining option as well, it may be applied to high-pressure and potable water pipes. It has outstanding cure capabilities and is the most adaptable lining system ever certified for use in potable water. As a result, projects are finished swiftly, safely, and affordably with little disturbance to operations, access, or the environment. This once again implies that the function of the pipe is restored more rapidly. A hybrid epoxy resin that is suitable for use in drinking-water applications is used to cure the range of nonwoven, staple fibre geotextiles used to make Greenline, which also has a 50-year product guarantee.


For pressurized metal pipe networks, such as those in fire suppression or drinking water systems, we offer Redline, a non-structural epoxy resin relining option. It may be fitted without causing damage to walls or structures and stops pollutants and microorganisms from leaking into pipe water. Using the available access ports, the resin is blasted into the pipe where it is then allowed to cure. It is a cost-effective and time-effective choice since it takes a fraction of the time that replacing pipes would. It guards against wear on metal chutes, flanges, elbows, and launders, restores the operational life of pipes, and lengthens its lifespan. It can survive being used with HVAC systems, fire suppression systems, conduit pipes, hot and cold potable water, greywater, compressed air, and more.

Signs That Your Pipe Lining Is Old

There aren’t many ways to check if your pipes need to be relined because they are underground. This is one of the reasons why it is difficult to spot the problems initially. However, just because you can’t see them doesn’t imply a problem doesn’t exist. There are several indicators that maintenance is overdue for your pipe, including: 

Backflow of water: When the water in the pipes begins to move backwards, you can be sure that it is time for you to get it repaired or replace your pipes.

Water of poor quality: Another sign that your pipe relining is old is when the quality of your water begins to deteriorate. It might become smelly or visibly colored.

Damaged Pipes: Your pipe should be attended to if it has been damaged. For example, your pipes could be pierced by the roots of a tree.

Funky odor in the yard: Odors are irritating and very unpleasant. It makes everyone uncomfortable, and anytime you get that odor, it is time to check your pipe lining. Another sign to watch out for is the groans and sounds that occur when you flush down the toilet.

Blockages or rust: Rust and blockage are also typical signs that your pipe lining is getting old.

If you encounter any of these situations, which are caused by the signs of a sewage line, you should get in touch with an expert.




Benefits of Pipe Relining

The advantages of pipe relining are numerous. Here are just a few of them:

  • Cost-Effective

Relining your pipes will most likely cost less than replacing them completely, especially when compared to the conventional method, which involves more time and more manpower.

  • No deep digging

Older techniques require digging trenches, which not only adds to the job’s expense, difficulty, and duration but also raises the chance of causing property damage. These dangers are minimized because pipe relining doesn’t involve any digging.

  • Relining pipes is often a short operation

It doesn’t take very long to reline domestic pipes. The length of the relining procedure varies from case to case, but in most circumstances, the entire task may be finished in a single day. Efficiency, cost-effectiveness, and general contentment are all benefited by this.

  • Long-term Outcomes

No-dig pipe repairs are carried out using a long-lasting resin that has been properly manufactured. The new casing is extremely robust once internally cured to the pipe system, thereby minimizing the likelihood that the aforementioned issues may materialize, at least for an extended length of time. Leaks are not a problem because of how well-sealed its anti-corrosive construction is.

  • Environment-Friendly

Pipe leaks are dangerous to the environment. By using a pipe relining method to combat this, effective drainage is made possible, lowering the danger that may be there. Additionally, the absence of digging operations results in less energy usage. You are losing control over our delicate ecosystem from beginning to end.





Cost of Pipe Relining

The cost of pipe relining can vary depending on the type of pipe, the size of the pipe, and the severity of the damage. In general, small repairs will cost less than large ones. Additionally, damage that is more severe will also cost more to repair. 

Pipe relining is typically more expensive than traditional methods of pipe repair, such as pipe bursting or pipe replacement. However, pipe relining can often be completed in a shorter timeframe and with less disruption to your property. This can save you money in the long run, as well as the hassle and inconvenience of traditional pipe repair methods.

Trenchless pipe relining typically costs between $6,000 and $12,000, or $80-250 per foot. Compared to regular pipe repairs, which may cost anywhere between $4,000 and $13,000, this is far less expensive. 

If you are considering pipe relining for your home or business, it is important to consult with a qualified plumbing contractor to discuss your options and get an estimate of the cost. With so many variables involved, it is difficult to give a definitive answer as to how much pipe relining will cost without knowing the specific details of your situation. However, a qualified contractor should be able to give you a general idea of the ballpark costs based on the type of relining system you choose and the extent of the damage to your pipes.

Factors that Affect the cost of pipe relining

The cost of pipe relining will be affected by a number of factors, including the type of relining system you choose, the extent of the damage to your pipes, the accessibility of your pipes, and whether or not you need to have any other repairs done at the same time.

  • Type of relining system

There are several different types of pipe relining systems available on the market, each with its own advantages and disadvantages. The type of system you choose will affect the cost of the project.

  • Extent of the damage

The more damage your pipes have, the more expensive it will be to repair them. If your pipes are only slightly damaged, you may be able to get away with a less expensive relining system.

  • Accessibility

If your pipes are difficult to access, it will be more expensive to repair them. This is because the relining process will require special equipment and training.

  • Additional repairs

If you need to have other repairs done at the same time as your pipe relining, this will also add to the cost.
