Drain Unblocking Haarlem

Drain unblocking in Haarlem: you call, we find it, we clear it

A blockage never comes at a good time, so we keep drain unblocking in Haarlem simple. Call 085 333 4698 at any time of day or night. We'll ask which drain is causing trouble, whether water is coming back up through other drains and what kind of home you live in: an upstairs flat in the Leidsebuurt calls for a different approach from a flat in Schalkwijk. From that, we can give you a price estimate straight away.

An engineer then comes out to you, usually within the hour. On site, they first establish where the blockage is and what's causing it, and then choose the right tools: a plunger or hand-held drain snake for a trap, an electric drain machine for a longer pipe, or a high-pressure water jetter for a sewer pipe full of grease and silt. Once the job's done, they test the drain and explain what was wrong.

Working in narrow streets and hofjes

In the Vijfhoek and around the hofjes, the almshouse courtyards of the city centre, space is tight, so the engineer brings portable equipment that fits through a narrow gateway or passage. If high-pressure jetting is needed, we first look for a rodding eye or an outside inspection chamber, so the hose doesn't have to run straight through your living room. That means less mess, and the job is often quicker too.

Where Haarlem's drains run into trouble

Haarlem stands on an old beach ridge, a band of sand between the dunes and the former Haarlemmermeer lake. As a result, the city centre sits on relatively firm, sandy ground. Schalkwijk, on the other hand, was built on former polder land, where the soil is softer. Together with the age of the housing, those differences determine the blockages we come across as a drain unblocking company in Haarlem.

City centre: old buildings and busy kitchens

There are plenty of restaurants and cafés around the Grote Markt and the Botermarkt, often with homes above them. Grease from commercial kitchens coats the pipes and combines with food scraps to form a stubborn blockage. In the older buildings, bathrooms and kitchens have also often been moved, leaving long horizontal drains with lots of bends. In the old centre, rainwater and waste water mostly end up in the same sewer. In a downpour, that sewer can't cope for a while, and water is forced back up into low-lying drains and basement flats.

Neighbourhoods from around 1900

The Rozenprieel, the Leidsebuurt and the Frans Halsbuurt have many houses divided into upstairs and downstairs flats. Several households drain into one soil stack, and the sewer connection to the street is often still the original one. When there's a blockage low down in the system, the downstairs flat is the first to know about it. In Kleverpark and the Koninginnebuurt, the roots of garden trees also play a part, especially where pipes have been in the ground for decades.

Delftwijk, the Amsterdamse Buurt and the Slachthuisbuurt

Delftwijk in Haarlem-Noord dates from the post-war rebuilding years, and its kitchen drains have handled more than half a century of grease and soap. In the Amsterdamse Buurt and the Slachthuisbuurt, on the eastern side of the Spaarne, renovated homes stand alongside original ones. That means modern plastic pipes and older drains lie side by side under the same street. The point where the two meet is a well-known spot for a blockage: a reducer where the pipe suddenly changes diameter, or a rubber coupling that has started to sag over the years.

Schalkwijk: high-rise on polder land

Most of Schalkwijk was built in the 1960s and 1970s. In high-rise blocks such as those in the Boerhaavewijk, many homes share the same soil stack, so a single object flushed by mistake can block the drainage for an entire block of flats. On Schalkwijk's softer ground, pipes can also subside: a pipe that no longer slopes evenly holds on to dirt and blocks more easily.

Sewer unblocking in Haarlem: when the problem is underground

If water comes up in several drains at once, or the whole ground floor smells of sewage, you have a blocked sewer somewhere beyond your home. Sewer unblocking in Haarlem then calls for a different approach from simply unscrewing a trap: the engineer needs to reach the sewer connection, and in this city it's by no means always where you'd expect it to be.

Pipes under a courtyard, an extension or the neighbours

In the city centre and the neighbourhoods from around 1900, the sewer connection doesn't always run in a straight line to the street. In a building with an extension or a courtyard that has been built over, the pipe sometimes runs underneath it, and in rows of old houses a drain can run some way beneath the neighbours' homes before it reaches the street sewer. Using a camera and a small transmitter on the head of the drain snake, the engineer traces the pipe from above. That way, they can pinpoint the blockage without having to dig blind.

Divided building, VvE or rented home: who handles what?

If a house with an upstairs and a downstairs flat has been legally divided into separate units, there is a VvE (owners' association), even if it rarely meets. The shared drain and the sewer connection are then a joint responsibility. As a rule, the municipality is responsible for the section under the pavement and the street; Haarlem municipality can tell you where that boundary lies at your address. If you rent, let your landlord know straight away that the drain is blocked. Afterwards, we tell you exactly what we found, so you can sort things out with the neighbours or the landlord.

Downpipes and gutters in the old town

On narrow, old buildings, the downpipe sometimes runs through the inside of the house rather than down the front, or the water from two roofs collects in a single gutter between the buildings. If a drain like that gets blocked with leaves or moss, the water spills over the edge and finds its way inside. In leafy neighbourhoods such as the Koninginnebuurt and around the Haarlemmerhout woods, gutters also fill up quickly in autumn. Our downpipe unblocking service clears the rainwater drainage right down to the section underground.

Common emergencies in Haarlem homes

Water in your shower whenever the neighbours upstairs do a wash

If you live on the ground floor of a house split into flats and water comes up in your shower as soon as the washing machine upstairs starts to pump out, the shared drain under your flat is partly blocked. The water from above can't get any further and looks for the lowest drain: yours. Ask the neighbours upstairs not to run the washing machine or shower for now, and keep an eye on the drain. The sooner the pipe is cleared, the less chance there is of water running into the hall.

The dishwasher pumps water into the sink

In renovated homes in the Rozenprieel or the Leidsebuurt, a new kitchen is often connected to an old drain. The dishwasher usually discharges through the trap under the kitchen sink. If the kitchen drain is half blocked, the water the dishwasher pumps out comes up in the sink, sometimes with bits of food in it. Switch off the dishwasher and stop using the sink. The blockage is often a few metres further on, where the kitchen pipe joins the soil stack. Unblocking the sink with a machine that reaches that far usually solves the problem in one go.

Plaster and tile adhesive after a renovation

Old Haarlem houses are often renovated, and during the work, buckets and brushes sometimes get rinsed out in the washbasin or the toilet. Plaster, tile adhesive and grout then set in the pipe into a rock-hard layer. If the toilet blocks or the washbasin drains slowly right after a renovation, that's often the reason. An ordinary drain snake won't get through it, so the engineer uses a machine with a cutting head instead. So rinse out DIY buckets outdoors and throw the sediment away with the building waste.

Services for every drain in your Haarlem home

Our drain unblocking in Haarlem covers much more than just toilets. We help with a blocked toilet, a washbasin that won't drain and a kitchen drain full of grease. If the problem lies further away, in the pipe under the floor or the garden, high-pressure sewer cleaning is often the answer.

If you have a blocked drain in Haarlem that keeps coming back, a drain camera inspection is often the quickest route to a lasting fix. In Schalkwijk, the footage regularly shows a sunken section of pipe where water collects. In Kleverpark or the Koninginnebuurt, we're more likely to find roots growing in through an old joint. And in the city centre, it sometimes turns out that a renovation years ago left one bend too many. With that knowledge, you know whether cleaning is enough or whether the pipe will need work at some point.

You don't need to know in advance which service you need. Just tell us what you can see and hear, and we'll decide on the approach.

Before the engineer arrives

In the meantime, there are a few things you can do yourself to stop the problem getting worse:

• Use as little water as possible and switch off the washing machine and dishwasher.
• For a washbasin or kitchen sink, try a plunger, covering the overflow first.
• Unscrew the trap under the washbasin over a bucket; the dirt is often sitting right there.
• If you live in a house divided into flats, warn the neighbours downstairs.

What not to do

Don't use harsh chemical drain cleaners. They rarely dissolve a greasy blockage or roots, they attack rubber seals and older pipes, and they're dangerous for the engineer who works on the drain afterwards. Don't poke a wire into a plastic trap or toilet either, as you can easily damage the bowl or the pipe. And don't keep flushing in the hope that it will clear by itself.

How to keep your pipes clear

Grease goes in the bin, hair in a strainer, and only toilet paper down the toilet. If you're planning to move a kitchen or bathroom in an old Haarlem building, get someone to check how the existing drain runs first. Extra bends and too little fall are the most common causes of blockages later on.
