Part of Mainline Group.
Who we are
Mainline Drains delivers drainage repair, maintenance and survey services for residential and commercial clients. We work with property owners, facilities teams and contractors when drains fail, need investigation or require planned renewal.
Mainline Drains is part of the wider Mainline Group, delivering specialist drainage services across the UK alongside our survey, security and groundworks divisions.
What we do
Our services cover the full drainage lifecycle — emergency call-outs, jetting and unblocking, CCTV inspection, relining, excavation and commercial maintenance. Examples include:
- Drain Collapse Repair
- Drain Relining
- CCTV Drain Surveys
- Drain Excavation
- Emergency Drainage
- Blocked Drains
How we work
- Brief and attendance. We clarify the issue, site access and urgency — including 24/7 emergency response where required.
- Diagnosis and options. We use CCTV and on-site assessment where appropriate, then recommend proportionate repair or renewal options with clear pricing.
- Delivery and handover. We complete agreed works safely, reinstate where needed and leave you with documentation suitable for insurance or compliance where relevant.
