How Disruptive Is a Full Replacement of Pitch Fibre Drains?

The Hidden Problem Beneath Your Home

If your property was built between the 1950s and 1970s, there is a good chance it still relies on pitch fibre drains. At the time, these pipes were seen as a modern innovation. They were light, easy to install, and affordable, which made them extremely popular across the UK. However, time has revealed their weaknesses.

Pitch fibre pipes were made using wood cellulose and bitumen. Over the years, this material has proven to be far less durable than originally thought. Exposure to heat, pressure, and moisture can cause the pipes to deform, blister, and eventually collapse. This leaves many homeowners facing serious drainage problems, such as slow drainage, blockages, or structural damage beneath their property.

When people discover that their drains are made from pitch fibre, the first question they often ask is, “How disruptive will it be to replace them?” The good news is that modern methods have made the process far more efficient and much less intrusive than you might expect.

What Is Involved in a Full Pitch Fibre Drain Replacement?

A full replacement involves removing the old pitch fibre pipes and installing brand-new drainage using modern, durable materials such as PVCu or vitrified clay. This often requires excavation, especially if the existing drains have already collapsed or are beyond repair.

The process usually begins with a detailed CCTV drain survey to assess the extent of the damage and to locate any areas that need special attention. This allows the team to plan the replacement accurately, avoiding unnecessary digging and reducing disruption.

The level of disruption depends on several factors, including the location of the drains, how deep they are, and how easy they are to access. If the pipes run under a driveway, patio, or extension, excavation may take a little longer than if they are located in a garden or open ground.

Full Replacement vs. Relining – Which Is Better?

Here is a simple comparison of the two options:

Full Replacement: This method offers a complete solution and provides a brand-new drainage system with a lifespan of 50 years or more. It is best for drains that have collapsed or suffered severe deformation.

Trenchless Relining: This option involves minimal disruption and is ideal for drains that are still intact but weakened. It typically lasts 30 to 40 years and can be completed quickly without digging.

At Pitch Fibre Specialists, we always begin with a detailed CCTV inspection so we can recommend the most suitable option for your situation.

Cost, Timeline, and Impact on Your Property

The cost of replacing pitch fibre drains varies depending on the size of the property, the layout of the drainage system, and how accessible the drains are. As a general guide, smaller replacement jobs may start from around £1,000, while larger or more complex projects can range between £3,000 and £6,000.

Although a full replacement represents a significant investment, it delivers peace of mind and long-term protection for your property. Modern drainage materials are resistant to corrosion, root intrusion, and structural damage, ensuring a lasting solution.
