The Most Powerful Way to Clear a Drain
High-pressure water jetting is the gold standard for clearing stubborn drain blockages and cleaning pipe walls. Our engineers carry professional-grade jetting equipment on every call-out across the West Midlands, Warwickshire, and Worcestershire.
How Jetting Works
A flexible hose fitted with a specialist nozzle is fed into the drain. Water at 3,000 PSI (pounds per square inch), roughly 200 times the pressure of a garden hose, blasts forward to cut through the blockage and backwards to propel the hose along the pipe. The rear-firing jets simultaneously scour the pipe walls, removing scale, grease, and mineral deposits.
The result is not just a cleared blockage, but a genuinely clean pipe. This is why jetting is far more effective than rodding for persistent or recurring blockages, as it addresses the build-up that causes them, not just the immediate obstruction.
Jetting vs Rodding: When We Use Each
Rodding is ideal for: soft blockages like toilet paper, light food waste, and soap scum. It is quicker, quieter, and included in our standard drain unblocking price. Most straightforward blockages are resolved by rodding.
Jetting is needed for: hardened fat and grease deposits, tree root masses, mineral scale, compacted silt, and recurring blockages. It is also the best method for preventative maintenance, removing build-up before it causes a full blockage. We particularly recommend jetting for homes in Birmingham and Coventry with Victorian clay pipes that accumulate mineral deposits over decades.
What We Jet Clear
🧴
Fat, Oil & Grease
The biggest cause of drain blockages across the region. Fat solidifies inside cold underground pipes and builds up into solid masses. Our jetting equipment melts and flushes it away. Essential for commercial kitchen drains.
🌳
Tree Root Masses
Roots that have grown through damaged pipe joints create a web that catches everything. Jetting cuts through root masses to restore flow. Regular jetting keeps roots manageable between repairs.
⚙️
Mineral Scale
Decades of hard water flowing through clay and iron pipes deposits calcium and lime scale on the pipe walls, gradually reducing bore diameter. Common across the West Midlands hard water area.
🪨
Compacted Silt & Debris
Soil ingress through damaged joints, leaves, grit, and general debris compact over time into a hard mass that rodding cannot shift. Jetting blasts it clear and flushes it downstream.
🧱
Concrete & Mortar
Builders leaving concrete or mortar residue in drains during construction work. A surprisingly common problem on new-build estates and properties with recent extensions across Solihull and Bromsgrove.
🛡️
Preventative Cleaning
Regular jetting before a full blockage develops saves money and stress. We recommend preventative jetting every 18-24 months for residential properties and every 6-12 months for commercial kitchens.
Commercial Jetting Services
Grease-laden waste from commercial kitchens is the single biggest cause of drain blockages in business premises. We provide scheduled jetting maintenance to restaurants, takeaways, schools, care homes, pubs, and food-processing facilities across the region.

When to Book Preventive Drain Jetting
Most drain blockages do not happen overnight. They build up gradually, starting with a slight reduction in flow that goes unnoticed until the pipe is completely blocked. Scheduled jetting prevents this cycle and saves you money in the long run.
Signs your drains need jetting: slow-draining sinks or baths, gurgling noises when you flush the toilet, persistent bad smells from gullies or manholes, and water pooling around drain covers after rain. Any of these suggest a partial blockage or build-up that jetting will resolve before it becomes a full emergency.
We recommend the following maintenance schedules based on property type:
Domestic properties
Every 18 to 24 months, or annually if you have mature trees near your drain runs. Properties in Birmingham and Solihull with heavy clay soil should lean towards the shorter interval, as clay soils cause more pipe movement and joint displacement.
Commercial kitchens
Every 3 to 6 months depending on volume. Restaurants, takeaways, and school kitchens produce high levels of fat and grease that solidify in underground pipes. A quarterly jet is far cheaper than an emergency call-out on a Friday evening.
HMOs and rental properties
Annually, timed between tenancies if possible. Higher occupancy means more use, more flushing of items that should not be flushed, and more demand on shared drainage systems. Landlords across Coventry and Birmingham benefit from scheduled maintenance to reduce emergency costs.
Properties with known root issues
Every 12 months until the affected section is repaired or relined. Jetting clears the root mass and restores flow, but roots will regrow into the damaged joint. Drain relining is the permanent fix, and jetting keeps you going until you are ready to proceed with it.
Drain Jetting Pricing
We believe in clear, upfront pricing with no hidden extras. Pricing is the same regardless of when you call. No extra charge for weekends, evenings, or bank holidays.
Domestic drain jetting
Single drain run jetted and cleared. Includes a post-jetting CCTV check to confirm the pipe is clean. No call-out fee.
Commercial maintenance contract
Scheduled jetting for restaurants, landlords, and facilities managers. Competitive rates for quarterly or bi-annual contracts.
If a job turns out to be more complex than initially described, we will advise you of the revised cost before starting. You will never be surprised by the bill.

How much does high-pressure jetting cost?
Our jetting service starts from £150 inc VAT with no call-out fee. Price depends on the length of pipe to be cleared and the severity of the blockage. We provide a fixed price before starting work. For routine preventative jetting, we offer competitive rates for regular customers.
Is high-pressure jetting safe for old pipes?
Yes, when used by experienced engineers. Our team adjust water pressure and nozzle selection based on the pipe material and condition. For very old clay or cast-iron pipes, we use lower pressures and specialist nozzles designed for fragile systems. We always CCTV check the pipe condition first on older properties.
What can high-pressure jetting remove?
Jetting is effective against fat and grease build-up, tree root masses, mineral scale deposits, hardened silt and debris, concrete residue, and general accumulations that rodding cannot shift. It is particularly effective for commercial kitchen drains with heavy grease loading.
How often should drains be jetted?
For residential properties, we recommend jetting every 18-24 months as a preventative measure, particularly for homes with mature trees nearby or older clay pipes. Commercial kitchens and restaurants should consider more frequent jetting, typically every 6-12 months depending on usage.
What is the difference between jetting and rodding?
Rodding physically pushes through soft blockages using manually operated rods. Jetting uses 3,000 PSI water to cut through hard-packed obstructions and simultaneously clean the pipe walls. Jetting is more thorough but rodding is often sufficient for simple, soft blockages. We carry both on every call-out.
Can you jet commercial drains?
Absolutely. We regularly serve restaurants, takeaways, commercial kitchens, pubs, care homes, schools, and industrial premises across the West Midlands. Fat and grease build-up is the primary issue in commercial kitchens, and jetting is the most effective way to keep these drains flowing. We offer maintenance contracts.
