DrainFixer provides blocked sink & basin unblocking across Old Coulsdon and the surrounding Greater London villages. We're a small family-run team — you speak to an engineer, not a national call centre, and you get a straight answer about what's wrong before anyone starts work.
London clay is unforgiving on old drainage. Ground movement over decades opens up joints in Victorian salt-glazed clay, and roots find those openings within a season. That matters for blocked sink & basin unblocking in Old Coulsdon, because the right fix depends entirely on what the ground is doing to the pipe.
It depends on the job — depth, access and what's actually causing the problem. We quote in writing on site before starting, so you approve the price first. Call 0330 1331 347 and we'll give you a realistic range over the phone.
Typical arrival: 30–50 minutes once you call. Old Coulsdon is around 13 miles from our East Grinstead base, and we run 24 hours a day, so emergencies in CR5 get priority.
Yes — every street in CR5, plus outlying hamlets and rural properties on private drainage across Croydon.
We place a bowl and towels before removing anything — nothing gets on your cupboard floor.
Occasionally, and only on modern PVC waste pipes. On lead or copper it accelerates corrosion. We prefer biological treatments as a maintenance option.
You speak to the people who turn up. No franchise, no handover.
Nights, weekends and bank holidays — the phone is answered by us.
