Drainage Maintenance & Repairs

Keep drainage problems investigated, maintenance organised and repairs followed through to completion.

Bigness Built Environment helps property owners and managing agents coordinate drainage maintenance and repairs across London.

From recurring blockages to damaged drainage systems, we organise specialist investigation, clearance and remedial work, keeping access, findings and outstanding actions under control.

Understand the Drainage Problem

We review the reported symptoms, affected areas and previous drainage history to establish the next practical step.

Slow drainage, repeated blockages, overflowing gullies or unpleasant odours may require investigation beyond the immediate obstruction. We coordinate appropriate specialists to assess the problem and recommend further work.

What We Can Help With

Depending on your building and agreed scope, drainage work can include:

• Internal waste pipes and soil stacks.
• External drains, gullies and inspection chambers.
• Recurring blockages and restricted flow.
• Specialist drain clearance and cleaning.
• CCTV drainage surveys.
• Damaged pipework, joints and connections.
• Rainwater drainage and downpipes.
• Planned cleaning and follow-up repairs.

Coordinate Clearance and Investigation

A blockage may be resolved through clearance, but repeated problems can indicate an underlying defect.

We arrange specialist attendance and appropriate cleaning or investigation methods. Where a CCTV survey is needed, findings can help identify the location and nature of defects before repairs are scoped.

Available reports, footage and recommendations are collected so the next steps can be clearly understood.

Address Recurring Drainage Faults

Repeated clearance without understanding the cause can leave the same problem unresolved.

We help review previous findings and coordinate specialist advice on damaged pipes, root intrusion, deposits or other reported defects.

Recommended repairs are defined and quoted for approval. Where further investigation is required, this is recorded as a separate action before permanent work proceeds.

Plan Drainage Repairs

Drainage repairs may involve local pipe replacement, specialist lining or excavation, depending on the condition and accessibility of the system.

Bigness coordinates the proposed scope, quotations, access and practical dependencies. Any associated opening-up and reinstatement works are identified within the proposal.

Technical recommendations and repair methods remain the responsibility of the appropriate specialist.

Organise Preventive Maintenance

Where drainage systems have known recurring needs, planned cleaning and checks can form part of the building maintenance programme.

We coordinate agreed visits around the system’s condition, usage and previous findings. Gullies, accessible drainage points and rainwater connections can be included where relevant.

Completed work and emerging defects are recorded to support future maintenance decisions.

Coordinate Access and Responsibilities

Drainage work can require access to occupied properties, communal areas, external grounds or neighbouring land.

We organise arrangements with the authorised building contact and clarify relevant work boundaries before instruction. Where a problem may involve a shared sewer or another party’s asset, responsibility needs to be established.

Any disruption, temporary restrictions and follow-up attendance are communicated as part of the agreed work.

What You Receive

Coordinated specialist attendance, a defined work scope and relevant investigation or completion records.

Unresolved defects and recommended follow-up actions remain visible. Clearance, surveys, repairs and reinstatement are priced within the quotation or agreed charging arrangements, with additional work submitted for approval.

Request Drainage Maintenance or Repairs

Tell us where the problem is occurring, which areas are affected and whether it has happened before.
