A blocked drain in St Ives escalates fast. The town's narrow cobbled lanes, dense cluster of fishermen's cottages, and intense seasonal occupancy mean drainage faults rarely give you breathing space. One overflowing gully behind a gallery on Fore Street, one slow toilet in a holiday let above the harbour, and within hours you have foul water surfacing on a flagstone floor or backing up into a courtyard at the height of the season. Clear Stream Drainage Solutions runs a 24-hour emergency drainage operation across St Ives and the surrounding TR26 postcode. Our certified engineers reach most addresses inside 90 minutes, with no call-out fee, no diagnostic charge, and a fixed price confirmed in writing before we start work.
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.

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.

Drainage faults give you warning before they flood a property. Acting at the first sign keeps the repair small and the cost predictable. The symptoms below are listed in escalating order of severity. By the third stage, stop running water through the system and call us.
A blocked drain announces itself before it floods. The earlier you act, the smaller the repair bill. The symptoms below are listed in escalating order. If you reach the third or fourth, stop running water through the system and call us.

Persistent Drain Odours
Gurgling From Plugholes And Toilets
Rising Water Or Wastewater Backflow
In an emergency, every minute counts. If you’re experiencing any of these issues, call us immediately on 01872 222555.
Avoid pouring caustic chemical drain cleaners down the system. They rarely shift solid blockages and they damage older clay and pitch fibre pipework, both common across St Ives’s harbour-side cottages.
A blockage cleared incorrectly comes back. Pouring chemicals, jetting at the wrong pressure, or pushing material further down the line all leave the underlying defect intact, which is why so many St Ives homeowners and business owners call a second contractor within months of the first. Our engineers diagnose the cause before they touch the pipe, then choose the technique that resolves it permanently.
Jetting is our default approach for grease, sand, silt, fat, and biological build-up, all of which accumulate quickly in a town with this density of restaurants, cafés, and high holiday-let turnover. The jet head shears soft and semi-solid material away from the pipe wall without damaging it. We calibrate the pressure to the age and material of the run, which matters in St Ives where Victorian clay and post-war pitch fibre still carry waste in many of the older harbour-side cottages.
Where roots, hardened scale, or compacted debris will not yield to water alone, we switch to electro-mechanical cutters. The rotating heads cut through the obstruction in stages, removing the material from the pipe rather than displacing it further down the system to cause a blockage somewhere else.
If a drain blocks once, clear it. If it blocks twice, survey it. Repeat blockages at the same point almost always indicate a structural defect: a hairline crack, a displaced joint, root intrusion, or a partial collapse. A CCTV drain survey in St Ives puts a high-definition camera inside the pipe so we can see the wall condition, gradient, and any defects directly. Our engineers record and timestamp the footage, mark the exact location of the fault, and explain what we have found in plain language. In most cases, no-dig drain relining resolves the defect without breaking up a slate floor, lifting cobbles in a harbour-side lane, or disturbing a gallery floor mid-season. For tight-access town centre sites and rural properties on granite, no-dig is often the only viable repair route.
A blocked toilet is one of the most disruptive faults a household or business can face, particularly in a single-bathroom holiday cottage at changeover or a busy harbour-side café in peak season. Water pooling around the rim, repeated flushing failures, or waste rising back into the bowl almost always points to an obstruction further along the soil pipe rather than at the toilet itself. We treat toilet unblocking in St Ives as a priority response. Our engineers clear the obstruction, check the connected pipework with a CCTV camera where appropriate, and confirm the cause so the same fault does not recur the next week.
Most first calls come during a crisis. The clients who stay with us long-term are the ones who move onto a scheduled inspection programme, because a planned visit costs a fraction of an emergency call-out and a damaged ground floor. We work with private homeowners, holiday let operators, lettings agencies, hotels, restaurants, galleries, harbour-side businesses, and farms across the St Ives area, and we shape maintenance schedules around occupancy patterns, seasonal trade, and the specific demands of pipework serving a town where summer load is several times the winter baseline.

Our team clears blockages quickly and safely, restoring full flow and preventing further damage to your system.

Drainage responsibility in St Ives trips up a lot of homeowners and business owners, and the wrong assumption can mean paying for work that is not yours to fund. As a rule, anything inside your boundary, including the lateral run from the property to the boundary line, is your responsibility. Once a pipe leaves your boundary and joins a shared sewer serving multiple properties, it falls under South West Water. The complication in St Ives comes from the town's dense historic layout, where shared private drains often run beneath neighbouring courtyards, alleys, and the warren of back lanes between the harbour and the upper streets before reaching a public sewer, and ownership is rarely clear from the deeds alone. Our engineers establish exactly where the fault lies, tell you whose responsibility it is in plain terms, and only quote for work you genuinely own. Where the defect sits on the public sewer, we provide the survey footage and report you need to pass to South West Water at no charge. For rural properties on private septic systems toward Zennor, Towednack, and the inland farms, the entire system is yours, including the tank, soakaway, and any shared connection between neighbouring cottages or smallholdings. We document the layout clearly so you understand precisely what you own.
Most central St Ives addresses are reached within 60 to 90 minutes. Properties in Zennor, Towednack, and the rural lanes can take a little longer at peak summer traffic, particularly on weekends when the A3074 into town slows to a crawl. We give you a realistic arrival window when you call rather than an optimistic one.
We agree a fixed price before any work starts, with no call-out fee and no diagnostic charge. The figure depends on the cause, location, and access, but you have the cost in writing before we touch the system.
No. Caustic cleaners rarely clear a real blockage and they degrade older clay and pitch fibre pipework, both common in St Ives's harbour-side and Victorian-era properties. Call us first.
Yes. Standard response across St Ives is 60 to 90 minutes, every day of the year, including weekends and bank holidays.
The recurring causes locally are fat, oil, and grease entering the system from the town's restaurants and cafés, root intrusion into Victorian clay runs, wet wipes and sanitary items flushed in holiday lets, sand and grit washed in from coastal surface water and beach traffic, and septic tank or soakaway failure on rural inland properties.
Yes. We run a genuine 24/7 emergency service with no out-of-hours surcharge applied to the fixed price.
