Our Fully Insured technicians are on call 24/7 to remove stubborn limescale, fat, and grease buildup from your drains and pipes. We provide a rapid, professional pipe descaling service across Cornwall.
A persistent blockage is one of the most frustrating problems a homeowner can face. Often, the first sign isn't a complete failure, but a series of recurring symptoms. If these issues seem familiar, it's a clear signal that a deeper problem is developing within your pipework.
Sinks, baths, or showers that empty very slowly.
Unpleasant odours coming from plugholes or drains.
Gurgling noises from the pipework after water has drained.
Toilets that are difficult to flush or where the water level backs up.
Frequent blockages that return, even after using shop-bought chemical cleaners.
Left unchecked, these issues can lead to expensive repairs or even damage to your property’s foundations. A professional drain inspection and descaling is the quickest and most reliable way to uncover and fix what’s really happening inside your drains before it becomes a bigger problem.
It’s a common frustration: you use a chemical cleaner, the drain clears for a week, and then the problem returns. This is because shop-bought solutions cannot fix the underlying issue.
Across Cornwall, the primary culprit is our extremely hard water. Over time, this causes heavy limescale deposits to form on the inner walls of your pipework. This hardened scale narrows the pipe’s diameter and acts like cement, trapping fats, oils, and waste.
Chemical cleaners might temporarily clear a small channel, but they cannot dissolve the hardened scale. Worse, these corrosive liquids can damage your pipework. In older cast iron pipes, this issue is often combined with tuberculation (corrosion buildup), creating stubborn, recurring blockages that only specialist equipment can solve.
Choosing a drainage specialist can be stressful. We make the decision simple by proving our professionalism, experience, and commitment to you from the very first call. We are the safe, certified, and experienced choice for your home or business.
Our engineers are not just-plumbers; they are highly trained specialists, certified in all aspects of drainage diagnostics and repair. They arrive in uniform, treat your property with respect, and are DBS-checked for your peace of mind.

EXCELLENT Based on 59 reviews Posted on Google IanTrustindex verifies that the original source of the review is Google. Excellent fast service. Very polite and professional.Posted on Google Rachel JonesTrustindex verifies that the original source of the review is Google. I recently used Clear Stream for a problem with a septic tank and could not recommend them more highly. From the initial call out onwards they were knowledgeable, professional, helpful and conscientious. They originally attended as an emergency call out. Despite it being the May bank holiday they arrived within an hour and charged a really reasonable price for an emergency service. When it became clear that the problem was significant and we would need a new tank they installed a temporary fix then provided a detailed quotation for the major works, including answering insurers’ questions. The new tank was installed over a two day period in which they work really efficiently, while keeping me updated and informed about every stage. The guarantees for their work are reassuring and they made a stressful situation so much easier. I would highly recommend them to anyone.Posted on Google Gina MartinTrustindex verifies that the original source of the review is Google. Josh - what a superstar.

For many blockages, our high-pressure descaling service is the perfect solution. However, in older properties with clay or cast iron pipework, descaling is often the first step toward a permanent fix.
If our CCTV survey reveals your pipes are cracked, damaged, or suffering from root ingress, the problem will eventually return.
In these cases, we recommend Pipe Relining as the definitive, long-term solution. This advanced "no-dig" technology creates a new, seamless, and super-tough pipe inside the old one. This permanent repair eliminates joints, seals cracks, and creates a smooth surface that scale and roots cannot grip, preventing future blockages for good.
If you live in Cornwall, your home has hard water. This means limescale buildup in your pipes is a "when," not an "if" problem. Don't wait for a stressful and costly blockage. A preventative check-up is always cheaper than an emergency repair.
Our Preventative Pipe Health Check is the ideal solution. We use our advanced CCTV cameras to diagnose your pipework’s condition and provide a light, preventative jetting service to keep your drains flowing freely, saving you thousands in potential future damage.

It's a simple 3-step process.
Yes, if your drains keep blocking, you need descaling. A simple unblock just pokes a small hole, but descaling cleans the real problem: the built-up scale. If you ignore it, the buildup will cause more blockages, bad smells, and could even crack or collapse the pipe. This is a much bigger, more expensive job to fix.
This is not a DIY job. Chemical cleaners are not strong enough to remove thick, hardened scale and can damage your pipes. This task requires specialist tools, like high-pressure water jets or mechanical cleaners. Our trained engineers have the right equipment to safely remove the buildup without harming your pipework.
Yes, there's a big difference. Unblocking just pokes a hole through a single blockage to get it flowing again; it's a temporary fix. Descaling is a full solution. We clean the entire inside of the pipe to remove all the hardened scale. This solves the root cause of the problem and stops it from blocking up again.
