Compare repair approaches and understand which method is right for your drainage problem.

Drain Relining vs Excavation

When a drain needs repairing, the two main options are no-dig relining and traditional excavation. Both are effective, but they suit different situations. Understanding the pros and cons of each helps you make an informed decision — and potentially save thousands.

How Drain Relining Works

Drain relining creates a brand-new pipe inside your existing damaged drain without any digging. A resin-saturated felt liner is inserted into the pipe, inflated against the pipe walls, and cured to form a seamless, jointless new pipe. Here's exactly how the process works.

How Long Do Drain Repairs Take?

The duration of a drain repair depends on the method used, the extent of damage, and the accessibility of the pipe. Here's a realistic guide to how long different types of drain repair take, so you can plan accordingly.

Is Drain Relining Worth It?

Drain relining is often presented as the modern, superior alternative to excavation — but is it always worth it? The honest answer is: usually yes, but not always. Here's a balanced assessment to help you decide whether relining is the right investment for your situation.

Drain Repair Methods Explained

Modern drainage engineering offers several repair methods, each suited to different types of damage and situations. Understanding the options available helps you ask the right questions and make informed decisions when your drainage engineer recommends a repair approach.

Patch Repair vs Relining

When a CCTV survey reveals damage to your drain, two no-dig options are often available: a targeted patch repair or a full-length reline. Both avoid excavation, but they suit different situations and budgets. Understanding the differences helps you make the right choice.

When Drain Excavation Is Needed

While no-dig methods like relining have transformed drain repair, there are situations where traditional excavation remains the only viable solution. Understanding when excavation is necessary helps you plan for the cost, timeline, and disruption involved.

Signs of a Collapsed Drain

A collapsed drain can go undetected for weeks or even months, causing increasing damage to your property. Knowing the warning signs helps you act quickly and avoid costly repairs. Here's what to look for and when to call a drainage engineer.

Bad Smells Coming From Drains

Persistent bad smells from drains are more than just unpleasant — they can indicate a serious problem with your drainage system. From broken seals to collapsed pipes, understanding the cause is the first step to fixing it.

Slow Draining Sinks and Toilets

Slow-draining fixtures are one of the earliest signs of a developing drainage problem. While sometimes caused by a simple local blockage, persistent slow drainage often points to a deeper issue in your underground pipework.

Inspection Guides

Drain Inspection

A professional drain inspection is the first step in understanding the condition of your drainage system. Whether you're investigating a problem, buying a property, or planning building work, our engineers provide thorough, detailed inspections.

CCTV Drain Inspection

CCTV drain inspection is the gold standard for diagnosing drainage problems. Our high-definition cameras travel through your pipes, providing real-time footage that reveals the exact condition of your drainage system without any need for excavation.

Drain Condition Reports

A drain condition report is a formal document detailing the state of a property's drainage system. Based on a comprehensive CCTV survey, it's used for property transactions, insurance claims, building regulation compliance, and maintenance planning.
