Blocked Storm Water Drain

How to Clear a Blocked Storm Water Drain?

At Blocked Drain Cleaning Bromley, we specialise in professionally clearing blocked storm water drains to ensure your drainage system functions effectively. Our expert approach combines advanced techniques, state-of-the-art tools, and years of experience to resolve blockages efficiently and safely. Here are eight key steps we take as professionals:

Thorough Inspection

We conduct a detailed inspection of the storm water drain to pinpoint the blockage. This includes visual checks and, where needed, advanced methods like CCTV drain surveys for accuracy.

Identifying the Cause

Understanding the cause of the blockage, whether it's debris, tree roots, or pipe damage, helps us determine the most effective clearing method. Identifying the source ensures the issue is fully resolved without unnecessary guesswork.

Surface Debris Removal

Our team clears visible obstructions like leaves, dirt, and debris from the drain grates and surrounding areas. This step prevents further buildup and prepares the drain for deeper cleaning.

Using High-Pressure Jetting

For more challenging blockages, we employ high-pressure water jetting to break apart stubborn debris and flush it out. This method is highly effective and ensures the pipes are thoroughly cleaned without causing damage.

Drain Rod Techniques

We use professional-grade drain rods to tackle blockages that may not respond to jetting. These tools allow us to dislodge clogs manually, especially in complex areas.

Root Cutting and Removal

If tree roots are the cause of the blockage, we use specialised cutting tools to remove them without harming the drainage system. This step ensures your pipes remain clear and free of obstructions.

Structural Assessment

After clearing the drain, we assess the condition of the pipes for cracks, collapses, or other damage. Addressing these issues prevents future blockages and maintains the system's integrity.

Preventative Maintenance

Finally, we recommend and implement preventative measures such as regular inspections, cleaning, and the installation of guards or filters. This ensures your storm water system stays functional and avoids recurring problems.

At Blocked Drain Cleaning Bromley, our professional approach ensures every blocked storm water is cleared efficiently and with lasting results. We deliver high-quality service to protect your property from water damage and flooding.

How Long Does It Take a Plumber to Unblock a Blocked Storm Water Drain?

The time it takes to unblock a rain water drain blocked depends on the severity and cause of the blockage. In most cases, a professional plumber can resolve a blockage within an hour or two using specialised tools such as high-pressure jetting or drain rods. The process is relatively quick and efficient for straightforward issues like a buildup of leaves, sediment, or debris. However, the exact duration can also depend on factors like the location of the drain and the ease of access. Prompt attention ensures the blockage doesn’t worsen or lead to additional complications. More complex blockages, such as those caused by tree roots, collapsed pipes, or extensive sediment buildup, may require additional time and effort. These cases might involve advanced techniques like CCTV inspections to locate the obstruction or even pipe repairs if structural damage is detected. While these situations may take longer, professional plumbers work diligently to resolve the issue as efficiently as possible. At Blocked Drain Cleaning Bromley, we aim to clear the blockage and ensure your stormwater drainage system functions perfectly for the long term.

How Much Does it Cost to Unblock a Blocked Storm Water Drain? 

The cost of unblocking a blocked storm water drain depends on several factors, which can influence the time, effort, and tools required to resolve the issue. Blocked Drain Cleaning Bromley offers transparent and competitive pricing while ensuring professional and effective service. Here are the main factors that can impact the cost of clearing a storm water drain blockage:

Severity of the Blockage

Simple blockages, such as accumulated leaves or minor debris, are usually resolved quickly and at a lower cost. Severe blockages, such as those caused by compacted sediment or extensive root intrusion, require more time and advanced tools, increasing the expense.

Drain Location and Accessibility

Easily accessible drains, such as outdoor grates, are less costly to service compared to blockages deep within underground systems. Drains in hard-to-reach areas may require additional labour and specialised equipment.

Size and Type of Drainage System

Larger or more complex drainage systems may take more time and effort to inspect and unblock. The design and layout of your storm water system can also affect the techniques and tools required, influencing the cost.

Inspection and Diagnosis Tools

The use of technology like CCTV drain inspections to identify the blockage can add to the cost but ensure an accurate diagnosis. This precision helps resolve the issue more efficiently, potentially saving money in the long term.

Clearing Methods Employed

The method needed to clear the blockage significantly affects the cost. Manual rodding or simple extraction is generally cheaper, while high-pressure jetting or root-cutting techniques, though more effective for tough blockages, can be more expensive.

Extent of Repairs Needed

The cost will increase if the blockage has caused or revealed structural issues, such as cracked or collapsed pipes. Repairs to damaged sections of the drain are essential for preventing future problems but will add to the overall price.

Preventative Maintenance and Upgrades

Some services include preventative measures, like installing filters or performing a thorough system clean to prevent recurring blockages. While this can increase initial costs, it often reduces future expenses by keeping your drains in optimal condition.

Emergency or After-Hours Service

Urgent callouts or services provided on weekends or evenings often incur additional charges. Scheduling regular maintenance during normal hours can help you avoid these extra fees.

What Can Cause a Blocked Storm Water Drain?

A blocked storm water drain can result from various factors, often leading to flooding, water damage, and costly repairs if not addressed promptly. Understanding the causes of blockages can help prevent these issues and keep your drainage system functioning effectively. At Blocked Drain Cleaning Bromley, we specialise in identifying and resolving these problems with professional expertise. Here are common causes of blocked stormwater drains:

Leaf and Debris Accumulation

Fallen leaves, twigs, and other debris can easily collect in stormwater drains, especially during autumn. Over time, this buildup can restrict water flow and create a blockage.

Sediment and Silt Buildup

Storm water often carries dirt and sediment, which can settle in the drain over time. This gradual accumulation reduces the system's capacity, leading to blockages during heavy rainfall.

Tree Root Intrusion

Tree roots can grow into storm water pipes in search of moisture, causing significant blockages. They obstruct water flow and may also crack or damage the pipes, worsening the problem.

Rubbish and Litter

Items like plastic bottles, wrappers, and other rubbish can enter drains through grates and cause obstructions. These materials can form a tough blockage that traps additional debris, exacerbating the issue.

Collapsed or Damaged Pipes

Structural issues, such as collapsed or cracked pipes, can block water flow. Ageing pipes, ground movement, or heavy loads on the surface above often cause these problems.

Grease and Fat Deposits

While less common in storm water drains, grease and fat can enter through improper waste disposal and solidify, creating stubborn blockages. These deposits are particularly problematic in commercial areas.

Improper Drainage Design

Poorly designed drainage systems with insufficient capacity or incorrect gradients can lead to blockages. These systems struggle to handle heavy rainfall, increasing the risk of water pooling and clogs.

Heavy Rainfall and Flooding

Intense storms can overwhelm drainage systems, pushing excessive water and debris into the pipes. This sudden surge can cause blockages, significantly if the system is partially obstructed.
