We’re not into half jobs or taking wild guesses. Our engineers have the experience and come with the gear that works to find the real problem. Once we spot it, we fix it right. Here’s a quick look at the main services we handle here in Seven Kings.
High-Pressure Water Jetting
Water jetting is our preferred technique for clearing most drain blockages due to its effectiveness, thoroughness, and versatility. Using specialised jetting equipment, we direct a powerful stream of water through the blocked area, breaking up common materials like oils, food particles, and hair.
This method is also capable of removing more difficult clogs such as root intrusions and hardened waste, making it ideal for situations where manual tools are unsuccessful.

Water jetting’s the answer. Fast, solid, and works nearly every time. We use water force to smash through grease, hair, food, and roots. Nothing else clears it out like this. Rods? Fine for minor blocks. Jetting? Built for the heavy stuff.

CCTV Drain Surveys in Seven Kings
If a blockage won’t stay gone, a CCTV drain survey helps us get to the bottom of it inside the pipes. Instead of pulling things apart or trying things blindly, we send in a camera the drain and get a good view. It shows us if there are breaks, wear, roots growing in, or a big old pile of gunk. That way, we know what’s going on and where to fix it.

Signs You Have a Blocked Drain
Sometimes drain problems are easy to spot. Other times, you’ve got to catch the little signs early to avoid a whole load of hassle. Here are some of the main things to keep in mind if you think something’s not right with your drains at home or work.
Water Draining Slowly
Slow drainage in sinks, bathtubs, or showers is often the initial clue of a problem starting within your plumbing system. In kitchens, the culprit is frequently buildup from grease and scraps, while in bathrooms, it’s typically a build-up of hair, soap residue, and mineral scale. If water is sitting, it’s a clear sign the system should be investigated.

Unpleasant Smells
Consistent bad smells coming from your drains are a strong signal that waste material, such as kitchen waste, cooking oils, or wastewater, is accumulating where it shouldn’t. These materials can become trapped within the pipework and begin to rot, releasing nasty gases. If you notice these odours near your sink, shower, or external drainage, it’s likely that a blockage is already taking shape and should be addressed promptly.

Gurgling Sounds From Pipes
Strange noises in your plumbing, especially noises that rise and fall, are often caused by air stuck in the system, which builds up when water is slowed down by a blockage. If your pipes are bubbling like a blocked sink, it’s a good idea to get it checked early.

Water Backing Up
A pretty obvious clue your drain’s blocked is when water doesn’t go down like it should. If you spot that happening, it’s a good idea to call someone in straight away before it turns into a bigger mess.
Toilet Flushing Poorly
Toilet not clearing or filling slow? Might be a clog in the soil pipe. Wet wipes, pads, or tissue usually to blame. Call it in.
Overflowing Outdoor Drains
Noticed water spilling from your outdoor drains when it rains? That might be a sign of something worse, it could mean there’s a blockage underground that’s stopping things from draining properly. If left too long, all that overflow can start damaging your garden. Time to call a pro before it gets any worse.
Multiple Fixtures Affected at Once
Multiple drains acting up? That’s not a minor fault. If toilets, sinks, and your washer are all blocked, the blockage is probably further down. Plunging won’t cut it. You need a proper look and jet gear to sort it for good.
Damp Patches or Mould
Hidden blockages can sneak up on you. One day everything’s fine, then suddenly, damp patches on the floor, mould in weird places, or a funky smell near the skirting board. If it doesn’t seem right, it probably is. And we can track it down fast.
