Frequently Asked Questions
Common questions about our drainage services.
How much does drain unblocking cost?
It depends on where the blockage is and how stubborn it proves. We give a clear price before any work starts, with no hidden charges, and because we are plumbers as well we can quote for the underlying fix if the blockage keeps coming back.
How quickly can you clear a blocked drain?
Most straightforward blockages are cleared in a single visit. For urgent problems such as an overflowing drain or a blocked toilet in your only bathroom, call us and we will get to you as fast as we can, 24 hours a day.
Why does my drain keep blocking?
Repeat blockages usually point to an underlying cause: a damaged or back-falling pipe, root ingress, scale build-up, or something in the drain run that catches debris. We investigate the cause rather than repeatedly clearing the same blockage.
Do you handle outside drains and gullies?
Yes. We clear external drains, gullies and downpipe connections as well as internal sinks, baths, showers and toilets. If the problem sits on the public side of the boundary we will tell you honestly and point you to your water company, who handle that side free of charge.
Is James Drainage a separate company?
No. James Drainage is the drainage arm of James Plumbing & Heating, run by the same team with the same insurance and the same standards. One number, one invoice, whichever trade the job needs.
