Definitive Drain Repair

Drain Repair & Excavation London

Structural drain failure requires a definitive, evidence-led repair strategy. We do not proceed without a comprehensive CCTV survey to isolate the exact defect, its classification, and the necessary excavation scope.

Our repair methodology is built on the diagnostic data. For collapses, fractures, or severe root ingress identified in Victorian terraces or modern commercial premises, we plan a precise excavation to minimise surface disruption and restore system integrity.

Every repair is documented with before-and-after CCTV footage, a detailed written report, and excavation plans. This evidence is critical for landlords managing portfolios, commercial property managers, and homeowners navigating insurance claims or property transactions.

Pricing is based on the repair scope defined by the CCTV survey findings. We provide a fixed-quote following diagnosis, with costs reflecting the defect's complexity, location depth, and required excavation.

What you get

Repairs Directed by CCTV Evidence: No excavation is planned without a full diagnostic survey to pinpoint the defect's exact location and severity.
WRc-Style Defect Classification: We categorise structural failures—such as fractures, collapses, or deformation—using standardised industry terminology in all reports.
Precision Excavation Planning: The excavation scope, whether in a Chelsea garden or a Camden mews, is determined by the survey to limit surface impact.
Post-Repair CCTV Verification: All repaired sections are re-surveyed to confirm the reinstatement's integrity and provide conclusive 'after' evidence.
Comprehensive Documentation Suite: Clients receive the full survey report, excavation notes, and verification footage for records or third-party submission.
Material & Method Specifications: Reports detail the repair methodology, pipe materials used, and jointing techniques applied for complete technical transparency.

How it works

A method, not a guess

Comprehensive CCTV Survey

We conduct a full internal drain survey to diagnose the structural defect. The footage is analysed, and a WRc-style classification is assigned to inform the repair plan.

Excavation Plan & Client Report

Based on the survey evidence, we provide a detailed excavation plan and written report outlining the defect, proposed repair method, and required access.

Precision Excavation & Repair

Our engineers perform a targeted excavation to expose the defective section. The damaged pipe is replaced or repaired using appropriate materials and techniques.

Verification & Final Documentation

A post-repair CCTV survey verifies the work. The final documentation pack, including all footage and reports, is issued to the client.

Questions

Drain Repair FAQs for London homeowners

Why is a CCTV survey mandatory before any repair?

A CCTV survey provides the definitive evidence required to plan a correct repair. Excavating without precise diagnosis risks unnecessary disruption, incorrect repair methods, and higher costs. The survey evidence is also essential for insurance.

What does WRc-style defect classification mean in your report?

It means we use standardised industry codes and terminology—like 'Fracture' (F), 'Collapse' (C), or 'Deformation' (D)—to categorise the fault. This provides a clear, technical description recognised by surveyors and insurers.

Do you provide documentation for insurance claims?

Yes. Our documentation suite is designed for this purpose. It includes the diagnostic CCTV footage showing the defect, the written report with defect classification, and the post-repair verification footage proving the repair was completed correctly.

How do you minimise disruption during excavation?

By using the CCTV survey to plan the smallest necessary excavation. We pinpoint the exact defect location and depth, allowing for a targeted dig. For repairs under drives or gardens, we aim for precise reinstatement of the surface.

Can you repair drains under buildings or extensions?

Yes, but access is more complex. The CCTV survey precisely maps the drain run and defect location. This allows us to advise on the most feasible access point, which may involve excavation from an adjacent area or internal floor, with full plans provided beforehand.
