Sink Unblocking in Hampshire
Kitchen or bathroom sink not draining? SouthFlow investigates and clears blocked sinks across Hampshire.

Kitchen sinks and bathroom basins across Hampshire
Kitchen waste pipes can accumulate grease and food debris; bathroom basin waste routes can collect hair and soap residue. Explain whether the sink is draining slowly, completely blocked or filling when another outlet empties. Water returning through several fixtures may indicate a restriction beyond the sink itself.
Tell SouthFlow what has already been tried and whether chemicals remain in standing water. For business premises, describe the impact on normal use and access arrangements. Agree whether the proposed work covers the internal waste route, external drainage or further investigation so the visit addresses the symptoms you have described.

What happens next?
Tell us what is affected
Provide the property postcode and describe the sink problem, including whether other outlets are backing up.
Discuss access and assessment
The position of the restriction and available access determine the appropriate approach.
Investigate recurring problems
If a blockage keeps returning, further drainage investigation or repairs may need to be considered.
What affects the cost of sink unblocking?
The location of the restriction, access, the work required and attendance time all affect the job. Explain the symptoms when requesting a quote and ask which work and charges are included.
Your questions answered
Do you clear kitchen sinks and bathroom basins?
Yes. Tell us which outlet is affected and whether it drains slowly, holds water or backs up when another outlet is used.
Why does my sink keep blocking?
Build-up in the waste route or a restriction further downstream may be involved. If the problem returns after clearance, share the history so the connected drainage can be considered.
What if other outlets are backing up too?
Report all affected outlets together. Several symptoms at the same time can indicate a restriction further along a connected drainage route rather than a problem confined to the sink trap.
Should I mention unblockers I have already used?
Yes. Tell us which products were used and whether standing water remains before anyone handles the waste pipe. Also mention trap cleaning or other attempts to clear it.
Does the service include the outside drain?
That depends on where the restriction lies and the work agreed. Ask whether the quote covers only the sink waste or includes connected external drainage and any investigation.
Can you help outside normal hours?
Yes. SouthFlow provides 24/7 drainage help. Explain the symptoms and their impact, then confirm attendance arrangements and charges for your address.
How much does the work cost?
We quote for the work your property needs. The price depends on the problem, access, preparation and attendance arrangements. When requesting a quote, ask what is included and whether VAT or additional investigation charges apply.
