Leaking Tap in Prague: Repair Costs & How to Fix

How Much Does It Cost to Fix a Leaking Tap in Prague?

A leaking tap in Prague typically costs between 800 and 3 000 Kč to repair, depending on the type of tap, what's causing the leak, and whether parts need replacing. A simple washer or cartridge swap sits at the lower end, while replacing the entire mixer unit or dealing with corroded pipework pushes the price higher.

If you're an expat living in a Prague apartment, a dripping tap might seem like a minor annoyance — but it wastes water, inflates your bills, and can cause damage to cabinets or flooring over time. Here's everything you need to know about getting it fixed properly and affordably.

What Causes a Tap to Leak?

Before you call a plumber, it helps to understand what's actually going wrong. Most leaking taps in Prague apartments fall into one of these categories:

Worn washer — the most common cause in older two-handle taps. The rubber washer inside the valve seat degrades and no longer seals properly.
Faulty ceramic cartridge — single-lever mixer taps use a ceramic disc cartridge. When it cracks or wears out, water drips continuously.
Corroded valve seat — mineral deposits from Prague's hard water eat into the valve seat, creating gaps where water escapes.
Damaged O-ring — if the leak comes from around the base or handle of the tap rather than the spout, a worn O-ring is likely the culprit.
Loose connections — sometimes the tap itself is fine, but the supply line connections underneath have loosened over time.

Prague's water supply is notably hard (high calcium content), which accelerates wear on internal tap components. If you live in an older panelák or pre-war building, your plumbing fittings may be decades old, making leaks more common.

Leaking Tap Repair Costs in Prague: Full Breakdown

Here's what you can expect to pay a plumber in Prague for common leaking tap repairs. These are typical market ranges — actual quotes will vary based on your location, the plumber's rates, and the complexity of the job.

Labour Costs

Callout / minimum charge: 500–1 000 Kč — most plumbers charge a minimum even for small jobs
Hourly rate: 400–800 Kč per hour — English-speaking plumbers may charge toward the higher end
Simple washer or O-ring replacement: 800–1 200 Kč total (including parts)
Ceramic cartridge replacement: 1 000–2 000 Kč total (cartridges cost 200–600 Kč depending on brand)
Full tap replacement: 1 500–3 000 Kč for labour alone — the tap itself is extra

Parts Costs

Rubber washer: 10–50 Kč
O-ring set: 30–100 Kč
Ceramic cartridge: 200–600 Kč (branded cartridges like Grohe or Hansgrohe cost more)
New mixer tap (mid-range): 1 500–5 000 Kč
New mixer tap (premium): 5 000–15 000 Kč+

A good plumber will diagnose the problem first and tell you whether a repair makes sense or whether the tap is old enough that replacing it is more cost-effective in the long run.

Does DPH (VAT) Apply?

If you hire a registered tradesperson (someone with an IČO), their quote may or may not include DPH (Czech VAT at 21%). Always ask whether the quoted price is s DPH (with VAT) or bez DPH (without VAT). Sole traders below the VAT threshold won't charge DPH, but larger firms will.

Can You Fix a Leaking Tap Yourself?

Replacing a washer or tightening a loose connection is technically straightforward. However, there are good reasons to call a professional instead of attempting a DIY fix, especially as an expat in Prague:

Older Czech plumbing is unpredictable — pipe sizes, thread types, and fittings in pre-1990 buildings don't always match what you're used to from the UK, US, or Western Europe.
Water shutoff valves may be shared — in many Prague apartment buildings, there's no individual shutoff for your flat. You may need to coordinate with the SVJ (společenství vlastníků jednotek — the owners' association) or správce (building manager) to shut off water for the whole riser.
Risk of making it worse — overtightening a corroded valve or cracking an old fitting can turn a drip into a flood, and water damage in a Czech apartment block can mean liability for neighbours' flats below yours.
Insurance implications — if a DIY repair causes water damage, your home insurance may not cover it. A professional repair with a receipt gives you documentation.

For anything beyond hand-tightening a loose aerator, calling a plumber is the safer and often cheaper choice in the long run.

How to Find a Plumber for a Leaking Tap in Prague

Finding a reliable plumber in Prague — especially one who speaks English — takes a bit more effort than in countries where online reviews are widespread. Here's a practical approach:

Get multiple quotes — don't accept the first price you're given. Comparing at least 2–3 quotes helps you spot outliers and find fair pricing.
Check their IČO — every legitimate Czech tradesperson should have a company registration number (IČO). You can verify it for free on ares.gov.cz, the official Czech business register.
Ask about the diagnosis — a good plumber will inspect the tap, tell you what's wrong, and explain whether a repair or replacement makes more sense before starting work.
Get a written quote — even for a small job, ask for a written estimate that includes labour, parts, and whether DPH is included. This protects both sides.
Ask about a warranty on the repair — reputable tradespeople stand behind their work and will come back if the same problem recurs shortly after the fix.

What to Tell the Plumber

When you contact a plumber, providing clear details upfront saves time and helps you get an accurate quote:

Where is the leak — kitchen, bathroom, or somewhere else?
Is it a single-lever mixer or a two-handle tap?
Does the tap drip constantly or only when turned on?
Is the leak from the spout, the base, or underneath the sink?
Do you know the tap brand? (Check for a logo on the handle or spout)
Can you shut off the water to that tap, or is it a shared valve?

Photos are extremely helpful, especially when communicating with a Czech plumber who may have limited English. A quick photo of the tap, the leak point, and the space under the sink tells more than a paragraph of text.

When a Leaking Tap Needs More Than a Simple Repair

Sometimes what looks like a simple drip is a symptom of a bigger plumbing issue. Call a plumber promptly — and expect a higher bill — if you notice any of these:

Water stains on the wall or ceiling below — the leak may be in the pipework behind the wall, not just the tap itself
Fluctuating water pressure — could indicate corroded supply pipes, a common problem in older Prague buildings
Rusty or discoloured water — suggests pipe corrosion that goes beyond the tap
Multiple taps leaking simultaneously — may point to a pressure issue or failing main shutoff valve
Visible mould around the tap area — the leak has likely been going on longer than you realised, and you may need both a plumber and a mould specialist

In these cases, the plumber may need to inspect the wider plumbing system, which can add 1 000–3 000 Kč or more to the total cost depending on what they find.
