How to Spot a Blocked Drain Before It Becomes a Bigger Problem

Blocked Drains in Norfolk, Covering Norwich, Cromer, North Walsham, Aylsham, Wroxham, Stalham & beyond.

A blocked drain rarely comes out of nowhere. Most problems start small — a slow sink, an unusual smell, a gurgle in the pipes — and become a messy (and expensive) issue if left untreated. Spotting the early signs can save you time, money, and the stress of an emergency callout.

Here’s how to recognise a developing blockage before it becomes a bigger problem:

1. Slow-Draining Sinks, Baths, or Showers

One of the earliest and most common signs of a blocked drain is slow drainage. Whether it’s a sink in Norwich, a shower in Stalham, or a bath in Cromer, water that takes too long to disappear usually means something is already restricting the pipe.

Fat build-up, hair, soap scum, or food waste are often the cause.

What to do: Start with hot water. If the problem returns, it’s likely deeper in the system, a CCTV drain survey can find the exact location before the pipe blocks completely.

2. Gurgling or Bubbling Sounds in Your Pipes

Gurgling noises are a classic early warning sign. This trapped air originates from wastewater struggling to pass through a forming blockage. We often hear this from customers in Wroxham, North Walsham, and the surrounding Norfolk villages.

What to do: Gurgling almost always means a blockage is developing. A quick drain unblocking appointment can stop it from becoming a full system backup.

3. Persistent Unpleasant Smells

Bad odours from sinks, baths, or outdoor drains often indicate that waste is stuck somewhere in the pipes. This is one of the most common reasons homeowners in Great Yarmouth and Aylsham contact us for advice.

What to do: If boiling water doesn’t shift it, the issue is most likely deeper in your drainage system. A professional drain clean or unblocking is usually the fastest fix.

4. Water Backing Up or Rising in Other Areas

When water appears in places it shouldn’t, such as rising in the sink when you flush the toilet, you almost certainly have a developing blockage in your main drain line.

This can happen in any property: from terraces in Norwich to rural homes near Stalham.

What to do: Stop using the system and arrange a CCTV survey or unblocking service with our team before you experience a wastewater overflow.

5. Unexplained Wet Patches or Pooling Water Outside

If you notice soggy grass, pooling water, or damp soil around your outside drains, you may be dealing with a blocked or damaged underground pipe.

We frequently see this in properties across Cromer, Aylsham, and Wroxham, especially in older homes with original pipework.

What to do: A quick inspection can determine whether you need drain unblocking, jetting, or no-dig relining.
