You moved into a beautiful apartment on a canal, or a 1920s upstairs flat in De Pijp, and within six months something went wrong with the water. A shower that trickles. A drain that gurgles in the flat below. A boiler that loses pressure every fortnight. It feels like bad luck. It usually isn't.

Amsterdam's housing stock behaves differently from almost anywhere else you've lived. The city is built on soft peat and clay, most of the old centre sits on timber piles, and a large part of the plumbing was retrofitted into buildings that were finished long before anyone thought about bathrooms. As an English-speaking plumber working across Amsterdam, we see the same handful of problems over and over — and they are nearly all Amsterdam-specific.

Here's what actually goes wrong in this city, why, and who is responsible for fixing it.

1. The city is settling, and your drains settle with it

Amsterdam's subsoil is a soft layer of peat and clay. To build on it, timber piles were driven down into the sand layer beneath — a technique used here since the seventeenth century. Timber survives indefinitely as long as it stays under the groundwater. When the groundwater drops, oxygen reaches the pile heads and fungi go to work. That's paalrot , pile rot, and it is the single biggest structural issue in the older parts of the city. The municipality runs a dedicated Funderingsloket (foundations desk) for exactly this reason, and Waternet monitors groundwater levels through roughly 2,500 measuring wells across the city.

You don't need a foundation problem to feel the effect in your plumbing. A few millimetres of settlement is enough to change the fall on a waste pipe. Wastewater needs a consistent downward gradient to carry solids away; take that gradient away and you get a flat run where waste sits, dries and builds up. The result is a drain that blocks every few months and unblocks easily each time — the classic sign that the pipe itself is the problem, not what you're putting down it.

It's most common in pre-war neighbourhoods: the Jordaan, De Pijp, Oud-West, De Baarsjes, parts of Oud-Zuid and the streets around the canals. Buildings with a mixed foundation — part timber, part concrete after a later repair — are worse, because the two halves settle at different rates and the pipework spanning them takes the strain.

What to do: if a drain blocks repeatedly in the same place, stop paying for repeat unblocking and get a camera inspection. Ten minutes with a CCTV camera tells you whether you have a fat build-up or a collapsed, dropped or back-falling section. We include camera inspection in our drain work from €129 incl. VAT.

2. Your building may be listed — and that changes what's allowed

Amsterdam's seventeenth-century canal ring has been on the UNESCO World Heritage list since 2010, and the city centre alone contains thousands of national monuments. If you live inside the Singelgracht, there is a decent chance your building is protected — and protection extends to the inside, not just the façade.

Under Dutch heritage rules the general position is that almost any alteration to a listed building requires a permit. There are two useful exceptions. Ordinary maintenance is permit-free, as long as the detailing, profile, shape, material and colour don't change — repairing a leaking pipe, replacing a length of copper with copper. And internal changes to parts of the building with no heritage value are also permit-free, which typically covers a bathroom or kitchen fitted in the 1970s or later.

In practice: a repair is a repair, and we can get on with it. A full bathroom relocation, cutting new chases into original walls or moving a soil stack is a different conversation, and worth checking with the gemeente before anyone lifts a floorboard. Discovering the permit question halfway through a renovation is expensive.

3. Lead pipes still exist in pre-1960 buildings

This one surprises most international residents. In Dutch buildings constructed before 1960, lead drinking water pipes may still be present in the private installation inside the property. Lead leaches into the water sitting in the pipe, and the legal limit for lead in drinking water at the tap is 5 micrograms per litre. Babies, young children and pregnant women are the groups most at risk.

Lead pipe is dull grey, soft enough to mark with a fingernail, and makes a flat, dead sound when you tap it with something metal — unlike copper, which rings. If water that has stood in the pipe overnight tastes different from water that has run for a minute, that's worth investigating too.

If you rent: this is your landlord's responsibility, not yours. Amsterdam tenants can get free, independent advice from Stichting !WOON, and the government has legislated a ban on lead pipes in rental homes and childcare locations through the building decree, with the commencement date being phased in. If you own: replacement is on you, and it is usually a straightforward job — the awkward part is access, not the plumbing.

4. Water pressure drops with every floor you climb

Amsterdam is a city of upstairs flats, and this is the physics nobody explains when you sign the lease. Water pressure falls by roughly 0.1 bar for every metre of height. Dutch guidance expects around 2 bar available at the connection, which is comfortable at street level — but a fourth-floor flat in a tall old building can be sitting near the bottom of the usable range before you've even turned a tap.

Add a narrow, scaled or partly restricted old riser and a thermostatic shower valve that needs a decent flow to hold temperature, and you get the two complaints we hear most: a weak shower, and a shower that swings hot and cold whenever someone else opens a tap. Taller buildings normally solve this with a booster set; in a converted canal house there often isn't one, and there's a limit to how much pressure can be conjured out of the mains.

One important distinction: your central heating pressure is a separate, closed circuit and has nothing to do with mains pressure. If your boiler gauge keeps dropping, that's a different fault with a different fix — we've covered that in how to top up your CV ketel, and the common warning codes in boiler error codes explained.

5. Limescale is probably not your problem here

If you've come from London, the south of England, or much of Germany, you'll have spent years fighting limescale. Amsterdam is different. Waternet supplies water with an average hardness of about 7.8 °dH, which counts as soft water, and the same water goes to Amstelveen, Diemen, Ouder-Amstel and Heemstede. Waternet's own position is that a water softener isn't needed here.

That matters diagnostically. When a shower head in a hard-water city runs badly, limescale is the first suspect. In Amsterdam it usually isn't. A poor shower here is far more likely to be height and pressure, a partly closed isolation valve, a failing thermostatic cartridge, or corrosion and debris from old galvanised pipework. Descaling the head won't fix any of those — and if someone in Amsterdam tries to sell you a water softener to solve a pressure complaint, be sceptical.

6. Blocked drain: is it yours, or the city's?

This is worth knowing before you spend money. Broadly, the sewer under the street is the municipality's responsibility, and everything from your property boundary inwards is the owner's. The dividing point is usually the boundary or the inspection chamber, and the exact line can vary by municipality.

The quick test is which drains are affected. One sink, one shower or one toilet misbehaving means the blockage is in your own pipework. Everything backing up at once — and the ground floor worst of all — points further downstream. In Amsterdam and Weesp, problems with the public sewer can be reported to the municipality on 14 020, and persistent sewer smells to Waternet. If you call a commercial company for something that turns out to be the city's section, you will almost certainly not get that money back.

Most of what we're called out to, though, sits firmly inside the property — and in old buildings with shared soil stacks it's often a communal riser serving several flats, which makes it a VvE matter rather than a personal one. We've broken the symptoms down in blocked drain or blocked sewer: how to tell, and the usual culprits in 5 things quietly blocking your drains.

7. Souterrains, cellars and crawl spaces flood

Amsterdam has a high groundwater table and a lot of half-sunken ground floors. A souterrain apartment, a cellar under a canal house or a crawl space under a ground-floor flat can take on water after heavy rain, after a burst pipe upstairs, or simply because groundwater found a route in through settled brickwork.

The damage compounds fast: standing water under a floor raises humidity through the whole building, and by the time you can smell it in the living room it has usually been there a while. If water is rising rather than falling, that's a same-night job — we run an emergency pump-out service 24/7 across the city. And if you suspect a slow leak rather than an obvious flood, the early warning signs are in how to spot a hidden water leak.

When to call

Amsterdam's buildings are wonderful to live in and unforgiving to plumb. A settling foundation, a listed interior, a pre-1960 pipe run and four floors of height loss are not problems you'll find in a modern apartment anywhere else — and they change both the diagnosis and the fix. The mistake we see most often is treating a symptom repeatedly instead of finding out what the building is actually doing.

If something in your Amsterdam home isn't draining, isn't heating or isn't holding pressure, we'll tell you in plain English what's wrong and what it costs before we start. Drain work from €129 incl. VAT, boiler work from €145 incl. VAT, no hidden call-out fees, one-month warranty, and typically on site within two hours.
