About Mainline Drains
Specialist drainage contractors for homes and businesses — from emergency response and blockage clearance to CCTV surveys, relining and commercial drainage. We focus on clear diagnosis, transparent pricing and work that is built to last.
Specialist drainage services across the UK.
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 continues to provide specialist drainage services across the UK. For groundworks delivery or surveying and site investigation on the same project, see Mainline Groundworks and Mainline Surveys below.
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.
