What does it cost to unclog a sink?
Unclogging a sink costs on average €300 per project. Most jobs fall between €150 and €500, depending on the severity and location of the blockage. Simple blockages that can be solved quickly cost from €100, while more complex blockages can reach up to €500.
Overview of sink unclogging costs
| Cost type | Price |
|---|---|
| Average costs | €300 |
| Average range | €150 - €500 |
| Minimum costs | €100 |
| Maximum costs | €500 |
Costs are calculated per project and depend on various factors. The professional first determines where the blockage is located and which method is needed to remove it. Blockages directly at the sink drain are usually cheaper to solve than blockages deeper in the piping system.
Plumbers often work with a fixed rate for standard unclogging work. Some professionals charge an hourly rate between €50 and €250 per hour, especially when the job turns out to be unexpectedly complex. For emergency jobs outside office hours, for example for serious blockages in the main line, the costs for a clogged kitchen drain can rise to €1,350.
All costs for unclogging a sink include 21% VAT and labour. Materials such as unclogging agents or drain parts are calculated separately if required.
Costs of unclogging a sink by method and location
The costs for unclogging a sink depend on the method the plumber uses and where the blockage is located. A simple blockage in the siphon is cheaper to solve than a blockage deeper in the main sewer line. Below you can see what different methods and locations cost.
Costs per method
| Method | Costs (materials and labour) |
|---|---|
| Snake | €100 - €300 |
| Electric snake | €250 - €400 |
| Hydrojetting | €400 - €650 |
| Clogged pipe cleaning | €550 - €800 |
Costs per location
| Location | Costs (materials and labour) |
|---|---|
| Waste disposal | €100 - €250 |
| Siphon (trap) | €100 - €300 |
| Drain | €100 - €500 |
| Main sewer line | €250 - €1,050 |
Price-determining factors for unclogging a sink
The costs for unclogging a sink vary greatly per situation. What makes one job quick and affordable can make another job complex and costly. Below you can read which factors influence the price and why.
Severity of the blockage
How serious the blockage is determines how much time and resources are needed. A plumber often solves a small blockage at the siphon within half an hour. This costs between €100 and €300. If the blockage is deeper in the main sewer line, heavier tools are needed and the labour duration increases. Costs can then rise to €1,050 or more.
Location of the blockage
The place where the blockage is located has a direct influence on the labour time. Blockages close to the siphon are easily accessible and quickly solved. Blockages in the main sewer line are deeper in the piping system and require specialist tools such as an electric snake or hydrojetting. This increases both the costs and the time required.
Method used
The plumber chooses the method based on the nature of the blockage. Manual snaking with a simple snake costs between €100 and €300. Hydrojetting, where water under high pressure cleans the pipe, is more effective for stubborn blockages but costs between €400 and €650. More complex blockages require more extensive pipe cleaning, which further drives up the costs.
Emergency versus planned work
Emergency jobs are significantly more expensive than planned work. For emergency calls outside office hours, the plumber charges a surcharge of €50 to €200 per hour on top of the normal rate. Blockages tackled during the day and on weekdays stay within the standard hourly rate of €50 to €250.
Weekends, evenings and public holidays
Work at weekends, in the evenings or on public holidays costs between €100 and €350 per hour. The time you call the plumber therefore has a direct influence on the total costs.
Accessibility of the sink
A difficult-to-reach sink extends the working time. If the sink is in a corner with little space, or the drain is behind cupboards, the plumber needs more time to get to the pipe. This increases labour costs.
Material and age of pipes
Older houses with cast iron or lead pipes require more careful methods. Aggressive techniques can damage old pipes, so the plumber works slower and uses milder agents. This can increase the total labour duration.
Complexity and underlying problems
If the blockage is the result of multiple problems, such as root growth or a subsided pipe, this extends the repair time. The plumber must first determine the cause and then apply an appropriate solution. This increases costs significantly.
Region
In large cities, prices are often higher than in rural areas. This is due to higher business costs such as rent and parking costs. Plumbers in urban areas pass this on in their hourly rates.
Season and busy periods
During holidays such as Christmas and New Year, blockages occur more often due to more intensive cooking. In these periods, the demand for plumbers can be higher, affecting availability and sometimes prices.
How can you save?
Do not postpone jobs. Fixing small blockages is more economical than repairing major damage. A blockage can lead to leakage or water damage, which multiplies the costs. Choose a local professional who can be on site faster and charges less travel time. Ensure the space under the sink is clear before the plumber arrives so they can get to work immediately.
Additional costs and surcharges for unclogging a sink
Extra costs when unclogging a sink depend on the time and urgency of the job. At Zoofy, you do not pay call-out charges.
- Emergency surcharge: For urgent jobs, the professional adjusts their planning, resulting in a surcharge of €50 to €200 per hour on top of the normal rate.
- Weekend surcharge: Work at weekends, in the evenings or on public holidays increases the hourly rate to €100 to €350 per hour.
- Camera inspection: In case of repeated blockages or suspected pipe problems, a camera inspection may be necessary, which involves additional costs.
How does the plumber work when unclogging a sink?
A plumber follows a fixed procedure to solve the blockage.
- Inspection and diagnosis: The plumber checks the symptoms, asks questions about when the problem started and what has already been tried. This helps to estimate the severity of the blockage.
- Localisation: Using visual inspection or camera inspection, the professional determines the exact location of the blockage. This determines whether the problem is in the siphon, drain or main sewer line.
- Method selection: Based on the diagnosis, the plumber chooses the most suitable unclogging method: manual snaking, electric snake, hydrojetting or clogged pipe cleaning. This choice influences the costs.
- Execution: The chosen method is applied. With manual snaking, a metal coil is pushed through the pipe. With hydrojetting, the professional uses a high-pressure water jet to remove the blockage.
- Check: The plumber tests whether the water flows away freely again and whether the problem is completely resolved. The job takes on average one to four hours, depending on the severity and location.
- Advice and preparation: The professional gives tips to prevent recurrence. Ensure free access to the space under the sink and have old towels ready before the plumber arrives.
How can you save on unclogging a sink?
There are several ways to reduce the costs for unclogging a sink.
- Prevent blockages: Regularly pour boiling water down the drain to melt away grease residues. Use a mixture of baking soda and white vinegar for slow-draining water. Addressing small problems early prevents expensive repairs.
- Clear the workspace: Remove items from under the sink and have towels ready before the plumber arrives. This saves labour time and therefore money.
- Choose the right time: Do not book at weekends or as an emergency if it is not urgent. During office hours on weekdays, rates are lower.
- Avoid DIY mistakes: Do not use aggressive chemical unblockers that can damage pipes. Do not try to disassemble the siphon yourself if you have no experience. Incorrect attempts can worsen the blockage and increase costs.
- Book via Zoofy: You get a fixed rate in advance, with no call-out charges and no surprises. You only pay after the job is completed.
Common causes of a clogged sink
Blockages arise from various causes, from daily use to structural pipe problems.
Grease accumulation
Fat, oil and grease solidify in the pipes and form a sticky mass that traps other particles. You recognise this by slow-draining water and a foul smell from the drain. As the grease layer gets thicker, the flow decreases.
Food residue
Coffee grounds, rice, pasta, eggshells and potato peels do not belong in the drain. Pasta and rice swell in contact with water and form a compact mass. These residues pile up in the siphon or further down the pipe.
Problems in the main sewer line
Root growth, subsidence or cracks in older pipes cause structural blockages. In this case, water comes back through other drains such as the shower drain or toilet. This increases the costs significantly because specialist tools are needed to work deeper in the piping system.

How long does it take on average to unclog a sink?
On average, it takes one to four hours, depending on the severity and location of the blockage. Simple blockages are often resolved within half an hour.
Can I continue to use the sink if the water drains slowly?
It is better to use the sink as little as possible until the blockage is resolved. Further use can worsen the blockage and increase damage.
What should I do if the blockage returns?
With recurring blockages, there may be an underlying problem, such as root growth or a damaged pipe. A camera inspection can identify the cause and help solve the problem structurally.
Are chemical unblockers safe for my pipes?
Aggressive chemical unblockers can damage pipes, especially older pipes. Use them sparingly or choose biological alternatives such as baking soda and vinegar.

Regularly pour boiling water down the drain, use strainers to catch food residue, and never throw grease or oil into the sink. These simple measures reduce the chance of new blockages.
How do I know if the problem is in my pipe or in the main sewerage?
If multiple drains are blocked at the same time or water comes back through other drainage points such as the shower or toilet, this points to a problem in the main sewer line. This increases the costs significantly.
