Drainage Repairs

When Repairs Can’t Wait

Cracked pipes, collapsed drains, root ingress, and corroded cast iron are not problems that improve with time. Left unaddressed, a minor drainage defect becomes a major structural failure — causing flooding, subsidence, foul odours, and health hazards in occupied commercial buildings.

The challenge for property owners and facilities managers is knowing what repair method is right. Excavation is sometimes unavoidable, but modern no-dig techniques like drain relining can restore structural integrity without breaking ground — saving time, cost, and disruption.

LDS specialises in diagnosing the problem accurately first (via CCTV survey), then recommending the most appropriate and cost-effective repair method. We never default to the most expensive option.

Our Process

How It Works

CCTV Survey & Diagnosis

We survey the drainage system to identify every defect precisely — location, severity, pipe material, and depth. No guesswork, no unnecessary excavation.

Repair Options & Quote

We present your options with honest recommendations. If relining can fix it, we say so. If excavation is needed, we explain why. Fixed-price quotes with no hidden costs.

Repair Works

Our engineers carry out the repair with minimal disruption. For relining work, there is no digging. For excavation, we reinstate surfaces and leave the site clean.

Post-Repair Survey & Report

We carry out a follow-up CCTV survey to confirm the repair is sound. You receive a full report with before/after footage and a warranty on the work completed.

Frequently Asked Questions

How do I know if my drains need repairing?

Common signs include recurring blockages, slow drainage, foul odours, damp patches, and subsidence. A CCTV drain survey is the definitive way to assess the condition of your drainage system.

What is drain relining and is it suitable for my property?

Drain relining involves inserting a resin-impregnated liner into the existing pipe, which hardens to form a new pipe within the old one. It is suitable for most pipe types and diameters and avoids the need for excavation.

How long do drain repairs take?

Relining repairs are typically completed within a day. Excavation work varies depending on depth, location, and the extent of damage — most commercial repairs take 1–3 days.

Will repairs disrupt my business?

We minimise disruption wherever possible. Relining requires no digging at all. For excavation, we work around your operational hours and reinstate all surfaces on completion.

Do you repair cast iron pipes?

Yes. We specialise in cast iron soil stack replacement and repair, which is common in older London commercial and residential buildings. We can replace sections or entire runs depending on condition.

Can you repair drains identified during a survey by another company?

Yes. If you already have a survey report identifying defects, we can provide a repair quote based on those findings. We may recommend a brief follow-up survey to confirm the current condition.

Do you offer warranties on repairs?

Yes. All repair work is warranted. Structural drain liners carry manufacturer warranties and our excavation work is guaranteed against defects.

What areas do you cover?

All London boroughs and the Home Counties. We carry out drainage repairs across the South East daily.
