We’re not into shortcuts or making assumptions. Our engineers have the experience and come with the gear that works to find the real problem. Once we get to it, we sort it properly. Here’s a quick look at the key services we offer here in Greenock.
High-Pressure Water Jetting
When it comes to unblocking pipes, we nearly always go for water jetting—it just works. It’s fast, powerful, and sorts out most of the usual problems. With jetting gear, we send pressure down the pipe and break up grease, old food, hair, and the usual grime. It’s even strong enough to take on bigger clogs, far more effective than using rods for the deep blockages.
Water jetting is one of the most reliable ways to clear drain blockages. We use focused water jets to force water through the clogged area, dislodging everything from food waste and grease to soap scum and organic matter. It’s also effective against deeper clogs like tree roots and compacted debris—jobs that traditional rods often can’t manage.

CCTV Drain Surveys in Greenock
When a blockage isn’t straightforward or difficult to diagnose, a CCTV drain survey provides a precise internal view of your underground infrastructure. Rather than relying on disruptive methods or trial and error, we navigate with high-definition cameras that navigate through the pipes, delivering live footage to our engineers. This process allows us to identify issues such as cracks, structural failure, tree intrusion, or excess residue. With this footage, we can pinpoint the exact cause and location of the problem and determine the right course of action.

Across Greenock, we support businesses with high-pressure water jetting, drain camera inspections, and appointments planned around your hours to keep business running.

Signs You Have a Blocked Drain
Sure, some drainage problems make themselves known fast. But most begin quietly. Spot the early signs and you’ll save yourself a ton of bother. Check out this list of common warning signs if you think your drains might be getting blocked.
Water Draining Slowly
Water not moving like before? If your sink, bath, or shower’s feeling slow, that’s usually the big hint. In the kitchen, it’s food and fat. In the bathroom? Bath muck are the biggest offenders. If water’s not moving, it’s time to jump on it.

Unpleasant Smells
That foul smell near the drain? That’s not just something in the air—it’s gunk building up, starting to break down. Food, grease, even sewage can get caught up. If you’re getting whiffs like that, don’t ignore it. It means a blockage is just starting, and it’s better to get ahead of it.
Gurgling Sounds From Pipes
Strange noises in your plumbing—especially gurgling or bubbling—are often caused by air stuck in the system, which builds up when water is slowed down by a blockage. If your pipes are making sounds like a kettle, it’s a good idea to get it checked early.
Water Backing Up
A pretty obvious clue your drain’s blocked is when water starts coming back up. If you notice it, it’s a good idea to call someone in straight away before it turns into a bigger mess.
Toilet Flushing Poorly
Toilet not flushing or taking too long? Might be a blockage in the drain. Wet wipes, pads, or tissue usually to blame. Time to clear it out.
Overflowing Outdoor Drains
If you notice water overflowing out of external drains during or after a storm, the issue may go deeper than simple surface runoff. A significant underground blockage could be stopping water from flowing, causing water to accumulate. Left untreated, this overflow can damage gardens, driveways, and even the structural foundations of your property. Prompt professional assessment is essential to prevent further complications.
Multiple Fixtures Affected at Once
When different parts of your plumbing in your property are struggling to empty at the same time, it’s often linked to a deeper issue within the central pipework. Such clogs can affect the function of toilets, sinks, bathtubs, and even washing machines. In these scenarios, simple methods like manual clearing are unlikely to be enough. A proper assessment using CCTV technology, followed by professional jetting, is typically recommended to identify and eliminate the obstruction.
Damp Patches or Mould
A drainage issue isn’t always obvious, but some signs can help you identify it quickly. If you’ve noticed damp patches on the floor or wall, mildew in odd corners, or a musty smell near kitchen units or floor edges, it could suggest a hidden leak or blockage.
