Blocked Drain Clearance services in Alresford
Common causes of blocked drains in UK homes include fat/oil build-up in kitchen waste pipes, hair and soap scum in shower traps, wet wipes and nappies in soil pipes, root ingress through cracked clay pipes, and collapsed Victorian sections in older properties.
A drainage specialist will normally start with a CCTV survey to identify the location and type of blockage, then clear it with high-pressure water jetting or mechanical rodding. Stubborn root ingress may require descaling or a no-dig liner repair.
If multiple drains are blocked at the same time — sink, bath and toilet — the blockage is downstream in the main soil pipe or sewer connection. That moves the responsibility for the repair from you to either Thames Water / your regional water board, or to a shared private sewer.

Frequently asked questions — Blocked Drain Clearance in Alresford
How much does drain unblocking cost in Alresford?
A standard unblock for a single sink or shower trap is £80–£150 in Hampshire. A whole-house drainage issue requiring high-pressure jetting and/or a CCTV survey runs £200–£500. Major sewer-line issues with no-dig liner repair start at £1,800.
When should I call a drainage specialist instead of unblocking it myself?
Call a professional when (1) multiple drains are blocked simultaneously, (2) there is sewage smell or backflow, (3) DIY chemical unblockers have not worked, (4) the blockage keeps coming back. Repeated blockages usually point to root ingress, a collapsed pipe or a fat/scale build-up that needs jetting.
Who is responsible for blocked drains — me or the water company?
You are responsible for the drains and waste pipes inside your property boundary. Once they connect to the main sewer (often at the boundary), responsibility shifts to the water company. If multiple homes on your street are affected, contact your water board — they may clear it free of charge.
What is a CCTV drain survey?
A small waterproof camera is fed into the drain to locate the exact position and nature of the blockage, root ingress or collapse. The engineer marks the spot above ground with a sonde locator. CCTV surveys are also often required for pre-purchase property reports and insurance claims.
