What is sewer unblocking and why is it crucial in Hilversum?
Unblocking a sewer involves removing blockages in the sewer system that hinder the flow of wastewater. Whether it's your kitchen drain, toilet, or the main sewer line under your home, a blockage can completely disrupt daily life. In Hilversum, where many homes are connected to a combined sewer system, it's particularly common for things like tree roots to grow into the pipes or for grease, soap scum, and dirt to accumulate. This causes typical problems such as gurgling sounds, unpleasant odors, a slowly draining sink, or a completely blocked toilet. Having your drains unblocked in time prevents pipe damage and nasty leaks.
What techniques do we use for sewer unblocking in Hilversum?
We utilize various scientifically proven techniques to efficiently unclog drains. Our technicians use methods like camera inspection, high-pressure flushing, and mechanical milling. These innovative tools and approaches guarantee a thorough solution without demolition or unnecessary costs.
- Camera inspection: Inspection cameras map blockages and damaged areas, allowing us to work precisely and efficiently without unnecessary demolition. Think of subsidence or ingrown roots along Bosdrift or Diependaalselaan.
- High-pressure cleaning: Using high-pressure water, we remove buildup of grease, limescale, toilet paper, and other deposits, ensuring optimal wastewater drainage. This is especially effective for larger main pipes in residential areas like 't Hoogt van 't Kruis or Trompenberg.
- Mechanical springs: With flexible springs and integrated rotating heads, we quickly clear stubborn blockages in drains and bends. Ideal for urban homes and apartments in Hilversum-Zuid or the city center.
- Hydrojetting: By flushing the entire sewer system, you prevent recurring blockages and unpleasant odors. We improve this with environmentally friendly cleaning agents that eliminate biofilm and grease without harming the environment.

Most common causes of sewer blockage in Hilversum
Hilversum's sewer system is heavily impacted and has remained in the same condition in some places for decades. Blockages are caused by:
- Grease and food residues: It often happens that frying fat, oil, or food scraps disappear down the drain unnoticed. These substances build up inside the pipes and cause blockages, especially as the sewer system ages.
- Toilet paper or wet wipes: Thick, non-biodegradable paper clumps together and blocks the toilet drain, leading to a complete blockage further down the sewer system.
- Tree roots: In older Hilversum neighborhoods such as Boomberg and Trompenberg, tree roots regularly enter the sewer system, causing major damage and blockages.
- Subsidence and cracks: Heavy rainfall, ground subsidence and wear and tear cause cracks in old stoneware pipes or PVC pipes, allowing sand or soil to enter the sewer.
Preventing blockages and maintaining your sewer
Prevention is always better than cure. As a drain cleaning service, we offer important advice and practical solutions:
- Flush regularly: Keep your drain clear by regularly using hot water with baking soda or baking soda. This will dissolve small grease plugs quickly.
- Prevent flushing of incorrect materials: Do not throw wet wipes, diapers, sanitary towels or cooking oil down the toilet or drain.
- Annual inspection: Sometimes a periodic inspection with a sewer camera is wise. This way, you can discover hidden weak spots or ingrown hairs early.
