Who We Are
A Blackburn-Based Drainage & Civil Engineering Contractor
Clear Flow Drainage & Civil Engineering is a Lancashire-based contractor offering a full range of drainage services alongside civil engineering and groundworks. We work with homeowners, landlords, letting agents, builders, developers and commercial clients across Burnley, Blackburn, Preston, Chorley, Lancaster and the surrounding area.
We handle everything from emergency drain unblocking at 2am through to planned civil engineering projects for commercial clients. Every job, large or small, gets the same level of attention and the right equipment for the task.
Our team is experienced across the full range of drainage work - CCTV surveys, high-pressure water jetting, root cutting, trenchless patch-lining repairs, jet-vac services, drain repairs, drainage installation and civil engineering. We don't cut corners and we explain what we've found in plain English.
