Common Signs of a Blocked Drain

  • Slow draining sinks, baths, or showers
  • Gurgling sounds from plugholes or toilets
  • Bad odours coming from drains or inspection chambers
  • Overflowing manholes or standing water outside
  • Backed-up toilets or flooding around gullies

Don’t ignore the signs — early intervention can prevent serious damage, flooding, and expensive repairs. Our engineers are equipped to handle any blockage fast, day or night.

How to Prevent Future Blockages

Once your drains are flowing freely again, taking simple preventative measures can save you time, money, and stress. Most blockages are avoidable with a few easy maintenance habits and regular inspections.

  • Avoid pouring fats, oils, or grease down sinks — they cool and harden inside your pipes.
  • Dispose of wipes, nappies, and sanitary items in the bin — even “flushable” ones can block drains.
  • Install drain guards to catch food waste, hair, and debris before they enter the system.
  • Schedule regular drain cleaning to remove silt or scale build-up before it becomes a blockage.
  • Book a CCTV inspection once a year for peace of mind and early fault detection.

Clearmasters offer planned maintenance packages for both domestic and commercial clients. These include scheduled jetting, inspection, and reporting to keep your drainage system working efficiently all year round.

Our Drain Unblocking Process

Every blockage is different, but our step-by-step process ensures a fast and effective solution every time.

1. Initial Inspection

We assess the symptoms and inspect your system using cameras or manual checks to pinpoint the cause.

2. High-Pressure Jetting

Our jetting units blast away blockages, grease, roots, and debris safely without damaging your pipes.

3. CCTV Verification

We use CCTV cameras to verify that the blockage is fully cleared and identify any underlying defects.
