There are several causes for a clogged sink. Do you want to unclog your sink? Then it is good to know what causes the clog. Possible causes are:
While using the sink, hair, soap scum and other debris will get into the sink. Over time, these will accumulate in the drain, which can lead to a clog. This type of clogging can be prevented by regularly removing hair from the drain and flushing the sink regularly with warm water and baking soda.
Water contains lime. In some cases, the sink becomes clogged because limescale builds up on the inside of the pipe. This can be a cause of the clogging in several drains.
All drains in your home drain into the main line, including the sink drain. When there is a blockage in the main line, several drains will no longer be able to discharge sewage and residue. If this is the case, you are dealing with a total blockage. Therefore, calling in a specialist is necessary to solve this total blockage.
If the sink isn't clogged by hair, soap and grime residue or blockages, there may also be something wrong deeper in the sewer system. For example, a broken or cracked drain pipe can cause multiple drains to fail. To determine the exact cause of the problem, you can call in a sewer expert. This expert will perform a sewer inspection with a camera so that the cause and also the right solution can be found as quickly as possible with the least possible inconvenience.
Choose a professional approach and have your sink unblocked by our skilled technicians! You can hire us for all types of unblocking, including sewer unblocking and shower unblocking.
The moment your sink is clogged, you can do two things: unclog it yourself or call in a sewer specialist. Often for clogs, it is best to call in a specialist right away. After all, our professionals have the right knowledge and resources to solve various clogs. In fact, unclogging the sink yourself can often make the situation worse. Usually the clog is too deep and there is a good chance that the problem will be made worse by wrong actions or the use of wrong resources. In the process, you can cause damage and wear and tear to the drain, which will incur further costs later on. Therefore, have your sink unblocked by a specialist. Our certified technicians will ensure that the sink is professionally unblocked and the water can flush properly again.
We understand that when calling in a specialist to solve your sewer problem, you are not waiting for unexpected surprises regarding the cost.

For superficial and minor clogs, you can try to unclog the sink yourself. We would like to give you some tips for sink unclogging for minor clogs:
For beginning clogs, you can unclog the sink by pouring buckets of warm water through it. When you see a whirlpool forming in the water, this is often the sign that the sewer connection is no longer clogged.
Baking soda is a natural wonder drug for solving minor clogs. For example, you can unclog your sink by flushing the drain with a bucket of hot water and baking soda. Baking soda is a cleaning salt that can loosen and dissolve dirt in the drain. Thus, you can unclog drain due to accumulations of soap and dirt residue.
If you are dealing with a lot of lime in the tap water, the best way to try to clean the drain is to flush through it a mixture of baking soda and vinegar. This combination will dissolve lime residue on the inside of the drain, allowing you to unclog the sink.
For unclogs located just behind the trap, you can also choose to disconnect the trap and clean it with water and baking soda. When disconnecting, do not forget to place a bucket under the siphon to catch water and debris. This method of sink unclogging can also be used for sink unclogging and drain unclogging.
Ploppers and unblocking springs can cause wear and tear to the pipe. Therefore, when unclogging a sink, always choose one of the above ways first or call in a specialist.
Note: You cannot use boiling water with a porcelain sink. This can crack the porcelain.
