Frequently Asked Questions

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.

Yes. We work with homeowners, landlords, property managers, and businesses across Cornwall. Our services include one-off emergency callouts, scheduled maintenance contracts, and planned CCTV surveys for commercial premises.
