Establish cause and ownership before major repair
A recurring blockage may sit in private drainage or in a public sewer. Do not authorise excavation until the defect and responsibility are reasonably clear.
- Say which drains or fixtures back up and whether the problem is intermittent.
- Mention neighbours being affected and any previous clearance work.
- Ask how call-out, jetting, CCTV and written reports are charged.
- Check whether United Utilities or the property owner is responsible before major repair.

Portsmouth drainage context
Recurring drainage faults can also create pest-entry problems, and larger alterations can involve Building Control
Portsmouth's rat guidance identifies old and defective drainage as a route into buildings. For projects that alter drainage rather than simply clear a blockage, the Building Control and sewer position should also be checked before work is covered up.
Old or defective drainage can give rats access to buildings
Portsmouth City Council says rats can gain access through old drainage systems as well as damaged airbricks and gaps around pipes. If blockages, smells or rodent signs keep returning, tell the drainage specialist about all of the symptoms so the underlying route can be investigated rather than repeatedly treating the surface problem.
Building work over a critical sewer has a specific Portsmouth Building Control restriction
Portsmouth City Council says a Building Notice cannot be used for an extension built over a critical sewer shown on Southern Water sewer maps. If drainage work is part of an extension or substantial alteration, establish the sewer position and approval route before excavation or construction begins.

Describe every affected outlet
Say whether the issue affects one sink, several fixtures, an outside gully or the whole property. Recurring smells, backing-up toilets and rodent signs can help distinguish a local trap problem from a larger drainage fault.
Recurring blockages need a cause, not just a temporary clear. Ask whether the quote is for unblocking only or includes CCTV inspection, tracing, repair and any follow-up work if the problem returns.
How it works

Up to three interested Portsmouth drainage professionals can respond.
Compare diagnosis and next step
Check reviews and distinguish clearance, CCTV, reporting and repair in each quote.
Before you hire
What should you check before hiring a drainage specialist?
For recurring problems, understanding the cause and ownership is more important than repeatedly clearing the same blockage.
Ask for the diagnosis
Request evidence of where and why the drain is failing before a major repair is proposed.
Separate charging stages
Clarify call-out, rodding, jetting, CCTV, reports and repairs as separate items.
Check responsibility
Establish whether the pipe is private or part of the public sewer network before authorising excavation.
Questions
Drainage Specialists in Portsmouth: common questions
Useful answers before you post the job.
How much does drain unblocking cost in Portsmouth?
The price depends on access, severity, equipment and whether investigation such as CCTV is needed. Ask what the call-out includes and how additional repair work would be priced.
Can damaged drains contribute to rat problems?
Yes. Portsmouth City Council identifies old drainage systems and pipework gaps as routes rats can use to enter buildings.
When might I need a CCTV drain survey?
A survey can be useful when blockages recur, the cause is unclear, structural damage is suspected or you need evidence of the condition before deciding on repairs.
Can I post an urgent blocked toilet or drain?
Yes. State that the job is urgent and explain which fixtures are affected and whether wastewater is overflowing or backing up.
Do I have to hire a drainage specialist who responds?
No. Up to three interested local professionals can respond and there is no obligation to hire.
