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. The only reason I haven’t given 5 stars is … I will have to pay the bill. Josh really put me at ease. I have been stressing about the blocked drain for two weeks. He got on with the job. Kept me advised all the way through the work. Would definitely recommend him. THANK YOU JOSH!!!Posted on Google Natasha RatcliffeTrustindex verifies that the original source of the review is Google.

Josh was quick to reply to my online query, and arranged to come out the same day. He quickly assessed the likely issue with the standing water and blocked drain, and promptly cleared it. His communication was great, I was advised of the cost up front, and everything was dealt with in a friendly and professional manner.

Stop using sinks, toilets, and washing machines connected to the blocked drain to prevent overflow. Do not use chemical drain cleaners, as these can damage pipes and push blockages deeper. Call Clear Stream on 01872 222555 for 24/7 rapid response, we reach most Cornwall locations within 1 to 2 hours.
Most blockages are caused by grease, wipes, hair, food waste, and foreign objects. In Cornwall's older properties, collapsed clay pipes, tree root ingress, and shifting ground from coastal erosion are also common. A CCTV drain survey identifies the exact cause so we can fix it properly, not just clear it temporarily.
Our engineers respond 24 hours a day, 365 days a year. We reach most Cornwall locations within 1 to 2 hours of your call, including Truro, Falmouth, Newquay, St Austell, Penzance, and surrounding areas. Call 01872 222555 for immediate response.
We charge no call-out fee and provide a fixed-price quote before any work begins. Pricing depends on the type and location of the blockage, access, and the equipment required. You only pay once you have agreed the quote in writing.
If the blockage is within your property boundary, it is your responsibility. If it is in a shared or public sewer, South West Water is responsible. Our engineers can identify which applies during the initial visit and advise you on the next steps.
Minor blockages in sinks or toilets can sometimes be cleared with a plunger. Chemical drain cleaners should be avoided as they damage pipes and rarely solve the underlying problem. For external drains, recurring blockages, or anything beyond a simple clog, call a certified drainage engineer to diagnose the root cause.
