What causes blocked drains in Harpenden?

Older properties in Harpenden 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.

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