What is sink blockage and why it is essential to have it resolved immediately
When the water in your sink no longer drains properly, you're dealing with a sink blockage. Grease, food particles, soap, hair, and limescale build up in your pipes, blocking the drain. A sewer smell often arises in the kitchen, and you'll notice that cleaning becomes increasingly difficult due to the lack of flow. Having a sink blockage resolved immediately is crucial to limit further disruption, as a clogged drain quickly affects other pipes in the house.
At Ontstoppen.nl We help you with advanced techniques and professional tools such as spring machines, high-pressure water jets, and camera inspection. These methods are proven effective and ensure that the blockage disappears completely. We are affiliated with certified industry organizations and work according to the NEN-EN 13508 protocol for pipe inspections. Our team offers complete transparency, works with fixed rates, and guarantees a fully functional sink drain within one day.
- Prevent water damage: An acute blockage can lead to leakage when water overflows the edge, risking damage to kitchen cabinets and floor
- Protect your health: Accumulated bacteria and mold can quickly develop around a blockage, causing unsanitary conditions
- Prevent unpleasant sewer smells: Stagnant water in the drain often causes a strong, unpleasant odor in the house that you would rather avoid
- Limit high costs: Quick intervention prevents the blockage from spreading to the main sewer, making expensive repairs necessary

- Foreign objects in the sink: Spoons, toothpicks, or plastic items sometimes accidentally end up in the drain. Even small objects can easily get stuck and cause a blockage.
- Incorrect use of cleaning products: Some products cause clumping or solidification between existing residues, making the blockage more stubborn.
