How much does drain clearance cost in Barnet?

A straightforward external drain blockage is usually at the lower end, while internal blockages or those requiring specialist equipment may cost more.

If you have sewage backing up or an overflowing drain, call the top-listed company directly — emergency call-outs are typically available 24/7 including weekends and bank holidays.
What causes blocked drains in Barnet?
The most common causes of blocked drains in residential properties around Barnet are fat and grease build-up (especially in kitchen drains), hair and soap scum (bathroom drains), tree root ingress (outdoor drains), and foreign objects like wet wipes and sanitary products. Older properties in Barnet may also have clay pipes that are more prone to cracking and root penetration.
Do I need drain clearance or drain repair?
Drain clearance removes blockages — hair, grease, debris, tree roots — and restores flow. It's a quick fix, usually completed in under an hour. Drain repair addresses structural damage like cracked, collapsed, or displaced pipes. If your drain keeps blocking repeatedly in the same place, you probably need a CCTV drain survey (£100-£200) to check for underlying damage. The companies listed above can advise on which service you need.
How do I know if a drain clearance company is trustworthy?
Look for companies with verified customer reviews, transparent pricing (a fixed quote before work starts), and no call-out charges.
