Pipe lining, or pipe relining, is an innovative plumbing strategy designed to restore cracks, leaks, and corrosion within a property's water lines, sewer pipes, or other plumbing, without the need for extensive excavation. At Sunset Heating & Cooling, we have mastered this advanced procedure, making it the preferred solution for homeowners and businesses facing serious plumbing issues in Portland, OR, and the neighboring communities.

The pipe lining process involves four key steps, resulting in a new pipe formed within the existing damaged one. Initially, our experts conduct a thorough inspection using a sewer camera to locate and assess the damage. The pipe is then cleaned to prepare for the insertion of a flexible liner coated with epoxy resin. This liner is inflated to fit the interior of the sewer pipe or other pipe and cured using steam or UV light, creating a durable, seamless new pipe inside the old one.

This method is not only highly effective but also cost-efficient compared to traditional pipe replacement. It preserves the integrity of your property’s plumbing system and landscaping, avoiding the disruption and expense of digging. With pipe relining from Sunset Heating & Cooling, you can significantly increase the longevity of your plumbing system while ensuring minimal environmental impact and waste.

When you opt for pipe relining services from Sunset Heating & Cooling in Portland, here’s what you can expect during the process:


The pipe lining process begins with a thorough inspection of the damaged pipe. Using a drain camera, our professional plumbers examine the pipe’s interior to assess the extent of the damage and determine the best course of action. This crucial step helps us ensure that relining is the appropriate solution for your plumbing issues.


Once the inspection is complete and pipe relining is confirmed as the best trenchless pipe repair solution, we prepare for the procedure. This involves gathering all necessary materials and setting up the equipment to ensure a smooth and efficient process.

Pipe Cleaning

The next step is cleaning the pipe to remove any debris, grease, or buildup that could interfere with the lining process. We use the hydro jetting method, employing a powerful tool that delivers water at very high pressure, to thoroughly clean the pipe. This ensures that the resin can adhere properly to the pipe’s interior surface.

Liner Insertion

After cleaning, we prepare the lining materials. The liner, typically made of fiberglass or polyester, is coated with a two-part epoxy resin. The liner is then inserted into the pipe using an inversion tank. The liner is inflated, pressing it against the walls of the damaged pipe, ensuring a tight and even fit. This process allows the resin to bond with the existing sewer pipe, creating a seamless, durable new pipe within the old one.

Quality Control

Although the pipe relining method consists mainly of the four steps above, we've added a fifth step to the task, which is quality control. We conduct a series of quality control tests to ensure the new pipe lining is properly installed and functioning correctly. This includes checking for any leaks and verifying the structural integrity of the new pipe. Our technicians ensure that your new pipe is as strong and reliable as a traditional pipe, capable of lasting many years.

By following these meticulous steps, Sunset Heating & Cooling ensures a high-quality, long-lasting pipe lining solution for your plumbing needs in Portland.

The Main Benefits of the Pipe Lining Method

  • Improved Flow. The pipe lining process enhances the flow of water and sewage through the pipes. The smooth, seamless interior of the new liner reduces friction and blockages, leading to better overall pipe performance.
  • Little Excavation Required. Pipe lining is a trenchless repair method, meaning it does not require extensive digging. This significantly reduces the need for heavy machinery and minimizes disruption to your property, preserving landscapes, driveways, and structures. Thus, if you’re looking for trenchless sewer repair, this is the method you should ask for.
  • Environmentally Friendly. Compared to other sewer repair methods, this is an environmentally friendly option as it produces minimal waste. By rehabilitating existing pipes rather than replacing them, it conserves materials and reduces the environmental impact of the repair process.
  • Resistance to Root Intrusion. Unlike traditional metal or plastic pipes, the seamless nature of the lined pipe makes it less susceptible to tree root intrusion. This reduces the risk of future blockages and damage caused by roots infiltrating the sewer line or other plumbing.
  • Durability and Longevity. The materials used for relining are highly durable and can last up to 50 years. This long-lasting solution ensures that your plumbing system remains in optimal condition for many years, providing peace of mind and reliability.
  • Faster Repair Time. Compared to traditional pipe repair methods, pipe lining is a much quicker process. The relining material can be inserted and cured within the existing pipe without the need for excavation, allowing repairs to be completed in a fraction of the time.
  • Cost-Effective. Pipe lining is a cost-effective solution. It eliminates the expenses associated with excavation and restoration of the affected areas. Additionally, by extending the life of your pipes, it reduces the frequency and cost of future repairs.

These benefits make pipe lining a superior choice for addressing plumbing issues, offering a quick, cost-effective, and durable solution with minimal disruption and long-term reliability.

    Pipe Lining vs Pipe Replacement: Which is Better?

    Pipe lining and pipe replacement both have their advantages, but the lining method is often preferred due to its trenchless nature, which means minimal excavation and disruption. Pipe lining is usually faster and more cost-effective, as it avoids the need for extensive digging and landscape restoration. Replacement, while sometimes necessary for old pipes, severely damaged sewer lines, or other damaged pipes, is more invasive and can be more expensive and time-consuming, but in the end, you’ll have completely new pipes.

    What Diameter of Pipes is Suitable for Pipe Lining?

    Lining methods are available for a wide range of diameters, from as little as 2 inches to 9 feet! However, the typical household pipe diameter range suitable for this method is 2 inches to 36 inches. This makes it an ideal solution for residential, commercial, and industrial plumbing systems. Our technicians can assess your specific pipe dimensions to determine if pipe lining is the best option.

    What Materials Are Used for Pipe Lining?

    The primary material used in pipe lining is a flexible liner, usually made from fiberglass or polyester, which is coated with a two-part epoxy resin. This combination creates a durable, seamless new pipe inside the existing one once cured. The epoxy resin is known for its long-lasting properties and resistance to corrosion and root intrusion.

    Is the Removal of the Pipe Lining Difficult?

    Once installed and cured, the pipe lining becomes a permanent part of your plumbing system and is not intended to be removed. However, if removal is necessary, it can be a complex process requiring specialized equipment and techniques. Fortunately, the durability and longevity of the lining mean that removal is rarely needed.

    What Issues Can Occur When Pipe Lining Isn't Installed Properly?

    If pipe lining is not installed correctly, several issues can arise. These include uneven curing, which can lead to weak spots or leaks, improper adhesion to the existing pipe, and misalignment, which can restrict water flow. Additionally, inadequate cleaning of the original pipe before lining can prevent the resin from bonding properly, leading to potential failures. Ensuring the process is carried out by experienced professionals, like those at Sunset Heating & Cooling, minimizes these risks and guarantees a high-quality result.
