How much does drain clearance cost in Farnham?
The typical cost for residential drain clearance in Farnham ranges from £100 to £250, depending on the severity and location of the blockage. A straightforward external drain blockage is usually at the lower end, while internal blockages or those requiring specialist equipment may cost more. Most reputable companies in Farnham offer a fixed price with no hidden call-out fees — always confirm the price before work begins.
Can I get same-day drain clearance in Farnham?

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 Farnham?
The most common causes of blocked drains in residential properties around Farnham 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 Farnham 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. Membership of trade associations like the NADC (National Association of Drainage Contractors) is a good sign. The companies ranked on this page have been assessed on customer ratings, review volume, and professional reputation.
