Blocked Drains: how Blocked Up handles it
An outside drain that is slow, smelly or overflowing is usually a build-up of fat, wipes, silt or roots somewhere along the run. Blocked Up Drainage clears the blockage with high-pressure jetting and drain rods, then checks the flow so you know it is gone, not just moved along.
If the same drain keeps blocking, we will tell you why. A CCTV survey can show whether there is a cracked pipe, a displaced joint or root ingress that needs a proper repair rather than another clearance.
Problems this solves
- Gully overflowing after rain or when the washing machine empties
- Manhole chamber full or lifting
- Standing water on the patio or drive
- Bad smells from outside drains
- Slow-draining drains across the whole house
- Roots and silt in older clay pipes
