Types and causes of sewer blockages in Purmerend
Drain unblocking in Purmerend is a broad term. Depending on the property and usage, there are common types of blockages:
- Toilet blockages: Excessive toilet paper, toilet blocks or wet wipes can severely block the drain.
- Kitchen drain blockages: Grease and food residues build up over time and cause a persistent blockage.
- Sink problems: Grease, soap residue and food quickly cause the pipe to clog.
- Rainwater drainage and downpipe obstructionsLeaves, sand and moss often cause blockages in outdoor sewers or rainwater drains.

In addition, tree root growth, subsidence of pipes due to the soft soil in Purmerend, or broken manhole covers can cause real headaches.

Common sewer problems in Purmerend and surrounding areas
Living in Purmerend means living on peat or clay soil, subject to subsidence and movement. This contributes to sewer blockages. Besides household causes, the Purmerend region also has typical problems:
- Subsidence due to soft subsoil: Due to soil subsidence, the sewer can kink or crack, which means that waste water can no longer be drained properly.
- Root growth in the main sewer: Trees in the neighborhood find their way into leaking joints and cracks in the sewer, causing blockages.
- Old stoneware pipes or lead pipes: Especially in older neighborhoods such as Overwhere and Purmer-zuid, there are still old sewer pipes that are easily damaged.
- Problems during heavy rain: Especially around Makado Shopping Center and the city center, basements or streets quickly flood during heavy downpours.
Our service isn't limited to Purmerend itself; we're also ready to unclog your drains in surrounding villages with our mobile service vehicles. For more complex problems affecting entire streets or business premises, we can flush the drains and clean the main sewer.

Frequently asked questions
What are the most common causes of a clogged sewer in Purmerend?
The most common causes of sewer blockages are accumulations of grease, soap scum, toilet paper, or foreign objects such as wet wipes. Tree roots growing in older sewer systems also often cause persistent blockages. Especially in the city center and older neighborhoods of Purmerend, we regularly see pipes corroded by years of deposits or subsidence.
For example, are you experiencing a gurgling drain, foul odors, or is the water in your toilet and sink draining more and more slowly? These are signs that you need to take action quickly. Our specialists at Ontstoppen.nl always check the entire process and intervene immediately with professional unblocking equipment. Also see how you can have a drain blockage resolved professionally for targeted tips.
How do I know for sure if my sewer is really clogged or if it is a local problem?
You usually notice a clogged drain when multiple drains in your home, such as the toilet, shower, or sink, are experiencing problems simultaneously. If only the toilet or sink is draining slowly, the problem is usually localized. However, if you have smelly drains, gurgling sounds when flushing, and multiple drains are backed up, chances are your main sewer is clogged.
At Ontstoppen.nl We always perform a thorough inspection to pinpoint the exact location of the blockage. Using camera technology, we quickly locate the blockage, allowing us to unclog it directly.

How much does it cost to unclog a sewer in Purmerend? Ontstoppen.nl and what about warranty?
For drain unblocking in Purmerend, we charge a fixed rate of €169,50 (including VAT) for a single blockage, regardless of the duration of the job. Is it the main sewer? Then you pay an all-inclusive flushing rate of €296,45. All costs include materials, VAT, call-out fees, and unlimited labor, so you'll never encounter any surprises.
Additionally, we offer a standard 8-week warranty on unblocking. If the blockage returns within that period, we'll fix it free of charge. No cure, no pay: if we don't solve the problem, you pay nothing. Transparency and reliability are always our top priorities.
Do I need to do anything beforehand if I notice that the sewer has become clogged?
If you discover that the water isn't draining properly or you smell a sewer odor in your home, first try to clear the blockage locally with a plunger, especially near the sink or toilet. Don't use chemical drain cleaners, as these can damage the pipes and make the problem worse. If possible, turn off the water in the event of an acute leak and make the problem area as accessible as possible for our technicians.
Call as soon as possible Ontstoppen.nl so we can be with you in Purmerend within 24 hours. Don't wait too long, because a small blockage can quickly spread to the main sewer, causing additional damage or inconvenience. Want tips on environmentally friendly practices?
