Question 4

What causes blocked drains in Harrow?

Accepted Answer

The most common causes of blocked drains in residential properties around Harrow 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 Harrow may also have clay pipes that are more prone to cracking and root penetration.

Question 5

Do I need drain clearance or drain repair?

Accepted Answer

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.

Question 6

How do I know if a drain clearance company is trustworthy?

Accepted Answer

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.
