If you’re dealing with blocked drains in Coulsdon, you’re not alone. It’s one of the most common problems people in the CR5 area face — and one of the most frustrating. Water starts backing up, the smell gets worse by the minute, and nothing you try seems to work.
So what’s actually going on? And more importantly / who can help?
What Causes Blocked Drains in Coulsdon?
There are a few usual suspects behind most Coulsdon drain blockages:
- Fat, grease, and oil – These harden inside pipes and trap debris.
- Wet wipes and sanitary products – Even “flushable” ones can clog your system.
- Tree roots – Especially in older areas like Chipstead Valley, roots can break into underground pipes.
- Broken or collapsed pipes – When pipes shift or collapse, blockages quickly follow.
DIY First Steps Before You Call Someone
Before picking up the phone, you might try:
- Pouring boiling water down the drain to soften greasy build-up.
- Using a basic plunger to shift simple blockages.
- Trying a mild drain cleaner (nothing too harsh — it can damage pipes).
These might give you temporary relief. But if the problem keeps coming back, or if water is overflowing, it’s time to call in a professional.
