CCTV Drain Surveys vs. Trenchless Drain Repairs: What's Best?

Dealing with mysterious drain smells, water backups, or slow-draining sinks? You're not alone. Drainage problems are a common household nuisance — and if left unchecked, they can lead to structural issues and costly repairs.

Thankfully, modern drain technology has come a long way. Two key techniques dominate today's solutions: CCTV drain surveys and trenchless drain repairs. But what exactly are they? When should you use them? And how do they compare? Let's dig in.

What is a CCTV Drain Survey?

Imagine diagnosing your drain problems without digging up your garden. That's what a CCTV drain survey does.

Using a high-definition waterproof camera, drain specialists inspect the inside of your drainage system. The camera captures real-time video, revealing everything from blockages and cracks to collapsed pipes and root intrusions.

Why Homeowners Use CCTV Surveys:

• Frequent blockages or foul smells
• Buying or selling a home (part of due diligence)
• Planning a home extension or loft conversion
• Preventive checks after flooding or heavy rainfall

You'll typically receive a detailed video report, highlighting any faults and recommending next steps — all without breaking ground.

What is Trenchless Drain Repair?

If a CCTV survey reveals damage, the next step might be trenchless drain repair — a no-dig alternative to traditional excavation.

Trenchless repair allows professionals to fix broken or deteriorated pipes without digging trenches. Two common methods include:

• Pipe Relining: A flexible liner coated in resin is inserted into the damaged pipe and cured in place, forming a new pipe within the old one.
• Pipe Bursting: The old pipe is fractured as a new one is pulled through the same path.

When to Consider Trenchless Repair:

• Pipes have cracked, shifted, or partially collapsed
• Drain lines run under driveways, patios, or buildings
• You want to avoid the cost and mess of excavation

Key Differences: CCTV vs. Trenchless Repair

In essence: CCTV surveys tell you what's wrong, and trenchless repairs fix it, without turning your garden into a construction site.

Which Should You Choose First?

The short answer? Start with a CCTV drain survey. It's a cost-effective way to understand the health of your drains.

Only after a clear diagnosis should you consider repair options — trenchless or otherwise. This avoids unnecessary work and expense.

In Summary

Both CCTV drain surveys and trenchless repairs are essential tools in modern drainage care. They reduce disruption, save time, and eliminate guesswork.

For most homeowners, the journey starts with a CCTV drain survey — a small investment that can prevent big headaches.
