A clogged sink is a common but extremely inconvenient problem. Water accumulates, odors begin to emerge, and often home remedies no longer work. But how much does it cost to unclog a sink, and what is the best way to solve the problem?
The price for unclogging a sink varies between €40 and €150, depending on the level of obstruction and the method required. Simple clogs are quick to fix, while deep blockages require professional tools.
If you are looking for specialized help, the best solution is to call a plumber in Lisbon. Our team at Canalizador de Lisboa is recognized for its speed, efficiency, and 24-hour availability, ensuring a safe and long-lasting service.
Common causes of sink blockages
To unclog properly, it is important to understand what is causing the blockage. Most blockages occur due to the accumulation of waste over time.
Fat accumulation
Fat poured down the sink solidifies inside the pipes, reducing water flow and forming plugs that are difficult to remove.
Food scraps
Food particles such as rice, pasta, or peels accumulate especially in the trap, causing frequent clogs.
Soap and detergents
Detergent residues can react with minerals in the water, creating thick masses that stick to the pipe walls.
Installation issues
Poorly installed pipes, misaligned siphons, or damaged parts can hinder drainage and increase the likelihood of clogging.
Practical solutions for unclogging the sink
There are several effective methods, some you can try at home and others that require professional intervention.
Home remedies
- Hot water to dissolve accumulated grease
- Baking soda and vinegar to loosen residue
- Rubber plunger for minor blockages
These methods are useful, but not always sufficient for deeper blockages.
Unclogging with a manual cable
The metal cable reaches deep into the pipe and removes stubborn blockages.
Disassembly of the siphon
Often the blockage is in the trap. Cleaning it manually usually solves the problem quickly.
Professional machines
For severe blockages, it is best to use electric or hydrojet machines, which completely remove the obstruction and clean the entire pipe.

In most cases, between 20 and 40 minutes.
