High-Pressure Water Jetting
When it comes to clearing drains, we nearly always go for water jetting—it just works. It’s quick, strong, and sorts out most of the usual problems. With high-pressure hoses, we push water through the pipe and break up grease, old food, hair, and whatever else has built up. It’s even strong enough to take on bigger clogs, way better than using rods for the tough stuff.
Water jetting is one of the most efficient ways to clear drain blockages. We use high-pressure hoses to force water through the clogged area, dislodging everything from common kitchen waste to hair and built-up grime. It’s also effective against tougher obstructions like tree roots and compacted debris—jobs that traditional rods often can’t clear.

CCTV Drain Surveys in Johnstone
If a blockage is stubborn or won’t fully clear, a CCTV survey is the best way to find out what’s happening inside your drains. We send in a small, high-definition camera into the system, allowing us to inspect the interior without digging. This footage helps us spot damage, tree growth, clogs, or pipe collapse, so we can pinpoint the issue and fix it right the first time.

Signs You Have a Blocked Drain
Sure, some drainage problems hit you right in the face. But most start small. 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 draining slow? Any fixture, it’s the start of trouble of a blockage. In the kitchen, it’s grease and scraps. In the bathroom, the usual suspects. Don’t wait. Sort it.

Unpleasant Smells
Foul odour from a drain? That’s a trouble alert. Waste, gunk, or worse is probably trapped. Smell it near the shower? Don’t wait. A mess is forming.
Gurgling Sounds From Pipes
Drains gurgling? That’s a sign of trouble. Usually means water’s fighting a blockage. If it sounds like a boiler, get help.
Water Backing Up
Water backing up? That’s a blocked drain. Don’t stall. get it fixed before it gets worse.
Toilet Flushing Poorly
A toilet that doesn’t flush properly or refills unusually slowly may indicate a restriction within the connected drainage system. These obstructions are often the result of foreign objects being flushed—common culprits include wet wipes, sanitary products, or excessive toilet paper.
Overflowing Outdoor Drains
Water rising up in outside drains after rain? That’s a red flag. Might be a serious backup. If water can’t get through, it backs up. That overflow? It can wreck gardens. Don’t risk it—get it sorted.
Multiple Fixtures Affected at Once
When several plumbing fixtures in your property are struggling to empty at the same time, it’s often linked to a system-level problem within the primary drainage channel. Such clogs can disrupt the function of several fixtures at once. In these situations, basic solutions like plunging are unlikely to be sufficient. A proper assessment using video diagnostics, followed by high-pressure water jetting, is typically needed to get rid of the obstruction.
Damp Patches or Mould
Sometimes it’s not easy to tell there’s a drain problem until you see moisture marks on the floor or walls. You might get mould popping up where it usually isn’t, or smell something odd near the kitchen units or along the base of the wall. That’s often a sign something’s gone wrong out of sight.
