Blocked Drains in Arundel - Common Causes, Costs and Fixes

Published October 2026 | Blocked Drains

Quick Cost Summary for Blocked Drain Work

Before you call anyone out, it helps to know roughly what the job should cost. Here is a breakdown of typical prices for blocked drain work across the Arundel area:

These are guide prices rather than guarantees. What you actually pay depends on where the blockage is sitting, how deep the drain runs, what method is needed to clear it, and whether there is any underlying damage that only becomes visible once the blockage is gone.

One thing worth knowing before you spend anything: not every drain blockage in the Arundel area is your bill to pay. More on that in the regional pricing section below.

What Factors Affect the Price

Blocked drain pricing varies more than most homeowners expect. Several distinct factors can push a job from 90 pounds to 400 pounds, and understanding them helps you ask better questions when you get quotes.

Severity and location of the blockage

A slow-draining kitchen sink caused by grease build-up close to the trap is a very different job from a completely blocked main soil stack backing up into multiple fixtures across the house. The deeper and further from an access point the blockage sits, the more time and specialist equipment the job takes. Our engineers typically find that blockages within the first metre or two of pipework clear quickly with rods, while blockages further down shared or deeper runs need jetting to shift properly.

Access difficulty

If the inspection chamber is buried under decking, sealed beneath a concrete path, or wedged into a tight corner of the garden, the engineer has to factor in extra time just to locate and open it. In some older properties the chambers have not been lifted in many years and may need significant effort to access safely. That preparation time gets added to your bill, even though it feels like it shouldn't.

Which method is required

Rodding is the cheapest approach and clears most simple blockages without any fuss. High-pressure water jetting is more effective on grease-compacted or heavily silted pipes - it costs more but does a far more thorough job and leaves the pipe walls cleaner, which reduces the chance of a quick re-block. CCTV surveys are necessary when there's a recurring blockage or suspected structural damage, since no amount of jetting will fix a collapsed section of pipe.

Time of day and day of week

Emergency callouts outside normal working hours cost noticeably more. Most drainage companies apply a callout fee on top of their hourly rate, and evening or weekend rates are commonly 50 to 100 percent higher than standard daytime prices. If you can safely contain the problem - using towels to protect flooring, turning off water at the stopcock if needed - and wait until the next morning, you'll typically save between 80 and 150 pounds compared to a same-night emergency attendance.

Whether additional repairs are needed

Blockages are sometimes a symptom of a deeper problem rather than the problem itself. A collapsed section of pipe, tree root intrusion, or a series of misaligned joints can cause repeated blockages that no amount of jetting will permanently fix. If a CCTV survey reveals structural damage, costs rise significantly. That's not the engineer trying to upsell you - it's what the drain needs to function properly long-term.

Regional Pricing - What Arundel and West Sussex Residents Typically Pay

Arundel is a small historic market town in West Sussex with a relatively limited pool of local drainage contractors. That lower level of local competition, combined with the travel time for companies coming from Worthing, Chichester, or Littlehampton, means you'll often find prices running slightly above the county average.

Based on what our engineers see across the BN18, BN17, and BN16 postcode districts, a standard residential drain unblocking job in Arundel during business hours typically runs from around 100 to 200 pounds. That's broadly in line with West Sussex averages, though at the upper end compared to what you'd pay in larger towns like Worthing or Crawley where there's more competition between drainage companies actively tendering for work.

Before you book a private contractor, it's worth understanding who is legally responsible for the drain. Since the 2011 private sewer transfer, shared sewers and the lateral drain beyond your property boundary are normally Southern Water's responsibility, while drains that serve only your property and sit within your boundary remain yours to maintain and fund. If your blockage is affecting neighbours or backing up from a shared chamber outside your boundary, call Southern Water first - they should attend at no direct cost to you. Getting this right before booking a private company could save you several hundred pounds.

If you are not sure which side of that dividing line your drain falls on, check the drainage map on the Land Registry portal, or ask Southern Water directly. Our engineers find this question comes up regularly on jobs in Arundel, particularly on older terraced and semi-detached properties where the original drainage arrangements weren't always clearly documented.

Labour Costs vs Parts Costs

Blocked drain work is almost entirely a labour-driven cost. Unlike boiler repairs or appliance fixes, there are very few parts involved in a standard drain unblocking job. What you're paying for is the engineer's time, travel, equipment, and expertise - not materials.

Here's roughly how the cost breaks down for a typical residential job:

• Labour rate: Most drainage engineers operating in and around Arundel charge between 60 and 100 pounds per hour. Some companies use a fixed-price-per-job model, which is generally better value for the customer on jobs that run longer than expected.
• Minimum callout charge: This typically covers the first 30 to 60 minutes on site. Expect to pay 80 to 120 pounds as a minimum even for a quick job, regardless of how little time it actually takes.
• Equipment costs: High-pressure jetting machines and CCTV camera systems are usually included within the quoted price rather than charged separately. Always confirm this upfront so there are no surprises on the invoice.
• Waste disposal: If the blockage involves significant amounts of silt, root debris, or waste material that needs removing from site, this may be charged separately. Ask when you book.
• Materials for repairs: For a pure unblocking job, materials are minimal. If replacement pipework is needed, PVC soil pipe typically costs 15 to 30 pounds per metre in materials, with fittings additional. Excavation and reinstatement - breaking up and relaying a path or patio - is usually the largest cost driver in a full repair job.

The Voltrade GoFIX diagnostic tool is worth using before you commit to a callout fee. It can help you assess whether your blockage is likely to be a quick unblock or a more complex structural repair, so you go into the conversation with the contractor better informed about what you're probably dealing with.

How to Avoid Getting Overcharged

Drainage is one of those trades where urgency can work against you. A backed-up toilet at 11pm puts you in a weak negotiating position, and a small number of operators will take advantage of that. Here is how to protect yourself.

1. Always get a quote before work starts. A reputable engineer will give you a fixed price or a clear estimate after a brief visual inspection. Be wary of anyone who declines to quote upfront and then presents a large invoice after the job is done.
2. Ask exactly what is included. Does the quote cover CCTV verification after clearing? Is waste disposal included? Is VAT included in the figure they're quoting, or will it be added on top?
3. Check for hidden callout fees. Some companies advertise low hourly rates but add a separate callout charge on top. Ask for the total cost of the job, not just the hourly rate.
4. Don't automatically choose the cheapest quote. A company that charges 80 pounds, rods the drain briefly, and declares it clear - when in reality the blockage has been pushed further along rather than cleared - will cost you more in the long run than one that charged 150 pounds to jet the pipe properly and then ran a camera to confirm it.
5. Look for recognised accreditation. NADC (National Association of Drainage Contractors) membership is not a legal requirement, but it's a useful indicator that a company operates to a recognised industry standard and has some form of professional accountability.
6. Ask whether they verify clearance with a camera. Good contractors will confirm the drain is fully clear after jetting, not simply declare the job complete because water is flowing again. A camera check adds maybe 30 to 45 minutes but gives you confidence the pipe is clear rather than partially shifted.

Is It Worth Repairing or Should You Replace?

This question comes up most often when a CCTV survey reveals something more serious than a simple blockage - a collapsed section, significant root intrusion, or widespread joint displacement. The answer isn't always obvious, but there are some useful rules of thumb.

When repair makes sense

Localised damage - a single collapsed section, a cracked joint, or a short run of deteriorated pipe - is usually best handled with patch relining or a targeted excavation and section replacement. Cured-in-place patch lining inserts a structural liner through the existing pipe from the inside, which seals cracks and reinforces the pipe without any digging. This typically costs between 500 and 1,500 pounds depending on pipe diameter, liner length, and access. For a single discrete problem, this is almost always cheaper than full replacement and causes far less disruption to your garden or driveway.

When replacement is the right call

If the CCTV survey shows widespread deterioration across a significant length of pipe - particularly in older properties where clay or pitch fibre pipes may have been in the ground for 50 or 60 years - full replacement can be more economical over a 10-year horizon than repeatedly patching one problem after another. The upfront cost is higher, typically 2,000 to 6,000 pounds or more for a complete residential drain run including excavation and reinstatement, but you're investing in a new system with a much longer expected service life.

Our engineers' general working rule is this: one localised problem is a repair job; three or more separate issues identified along the same run in a single survey is a replacement conversation. A CCTV survey, at 150 to 350 pounds, gives you the information you need to make that call on the basis of evidence rather than guesswork. In most cases it pays for itself by avoiding either unnecessary repairs or unnecessary full replacement.

Getting Quotes - What to Ask Before You Commit

When you contact drainage companies to serve the Arundel area, the questions you ask upfront will determine whether you end up with a fair price or a nasty surprise. Here's what's worth covering before anyone starts work.

1. "Is this a fixed price or time-and-materials?" Fixed price protects you if the job runs long. Time-and-materials can be fine for simple jobs but creates risk on complex ones where the scope isn't fully clear at the outset.
2. "What is your callout fee, and is it included in the total?" Some companies absorb the callout into the job price; others add it on top. Know which model you're dealing with before you agree to anything.
3. "If rodding doesn't clear it, what happens next - and what does that cost?" Understand the escalation path and its pricing before the engineer starts. You don't want to agree to a 90-pound rodding job and then find yourself committed to 250 pounds of jetting because rodding didn't work and no one mentioned the escalation cost upfront.
4. "Does the price include CCTV verification of clearance?" Without this, you're taking the engineer's word that the drain is properly clear.
5. "Do you carry waste carrier registration for spoil and debris removed from site?" This is legally required for the legitimate disposal of drain waste. If they don't have it, the waste could end up disposed of improperly, which could create a liability for you.
6. "What public liability insurance do you carry?" High-pressure jetting can occasionally damage older or already-compromised pipework. Confirm their insurance covers accidental damage before they start.

It also helps to describe the problem accurately when you first make contact. How many fixtures are affected? Is it a complete backup or a slow drain? Is there any gurgling from other drains when this one is used? Has it happened before? The clearer your description, the more accurate the initial estimate will be, and the less likely you are to get an unexpected revision once the engineer is on site.

Price-Related Questions About Blocked Drains in Arundel

How much does emergency drain unblocking cost in Arundel?

Emergency callouts in Arundel typically cost between 200 and 450 pounds for out-of-hours attendance. That reflects a callout premium added on top of the standard job rate, plus higher evening and weekend hourly charges. Where the situation allows, containing the problem temporarily and waiting for a next-morning appointment will commonly save you 80 to 150 pounds compared to calling someone out the same evening.

Who is responsible for a blocked shared drain in Arundel?

Since the 2011 private sewer transfer, Southern Water is responsible for shared sewers and the lateral drain running beyond your property boundary in Arundel. If a blockage is confirmed to be in the shared section, report it to Southern Water and they should attend and clear it at no direct charge to you. Only drains serving solely your property and sitting within your property boundary are your responsibility to fund.

What are the most common causes of blocked drains in homes?

Most blockages occur because everyday items enter the drainage system that simply don't belong there - fats, oils, and grease are among the most frequent culprits. In kitchens, accumulated cooking fat is the leading cause of drain blockages. In bathrooms, hair, soap scum, and products marketed as "flushable" but which aren't are the main offenders. In older properties with established trees, root intrusion is a significant cause of recurring and structural blockages that won't clear with jetting alone.

How long does a drain unblocking job typically take?

A simple blockage cleared by rodding typically takes 30 to 60 minutes from the engineer arriving on site. High-pressure jetting takes a similar amount of time but may run longer on heavily silted or grease-compacted pipes. Adding a CCTV survey at the same visit adds roughly 30 to 45 minutes. More complex jobs involving structural damage, difficult access, or multiple blocked runs can take half a day or more.

Can I clear a blocked drain myself before calling a plumber?

For minor blockages - a slow-draining sink or shower - it's worth trying a plunger or a proprietary drain cleaner before booking a callout. These can shift a partial blockage near the outlet and save you a callout fee. Avoid chemical cleaners in older pipework or if you're on a septic tank. For anything involving a manhole, a recurring blockage, a complete backup affecting multiple fixtures, or any sign of sewage backing up, stop and call a professional rather than risk pushing the problem deeper or missing a structural issue.
