A leak in the house: what should you do straight away? 7 steps to limit the damage

A leak in the house can start small, with a damp patch, a dripping sound or a sudden drop in water pressure. Yet even a small leak can quickly cause damage to ceilings, walls, floors, insulation and electrics. That is why it is important to act quickly and calmly.

In this guide you will read what you can do straight away if there is a leak, how to assess the possible cause and when professional leak detection is sensible.

What should you do straight away if there is a leak in the house?

1. Limit the water supply

Is the water clearly coming from a pipe, tap, toilet, central heating system or another part of the water installation? Then, if it is safe to do so, close the relevant isolating valve or the main stopcock. That limits the amount of water that can escape.

Don’t know where the main stopcock is? It is often in the meter cupboard, under the stairs, by the front door or near the water meter.

2. Watch out for electricity

Water and electricity are a dangerous combination. Is the water getting near sockets, lighting, electrical appliances or the meter cupboard? Then do not touch wet electrical parts. Only switch off the power if you can do so safely.

3. Catch the water and protect your belongings

Put a bucket or tray under the leak and move furniture, electronics, rugs and other vulnerable belongings out of the way. Lay down towels or absorbent material to stop the water spreading.

4. Take photos of the damage

Take photos, and if possible short videos, of the damp patch, the leaking part and the damage that has occurred. This helps a professional assess the problem better beforehand and can also be useful when you contact your insurer.

5. Look for the possible cause

Only check visually where the water seems to be coming from. Common causes are:

• a leaking water pipe or coupling;
• a broken sealant or grout joint in the bathroom or kitchen;
• a drain that is leaking or blocked;
• a central heating pipe, radiator or boiler that is losing water;
• a leak from the roof or around a roof penetration;
• a leak at the toilet, shower, bath or washbasin.

If you cannot see straight away where the water is coming from, targeted leak detection in Almere can help avoid unnecessary breaking-open work.

6. Do not just seal the leak permanently yourself

A temporary fix can sometimes limit further damage, but sealing or taping over a leak without knowing the cause can shift or hide the problem. Especially with pipes in walls, floors or ceilings, it is important to establish the cause before repair work starts.

7. Call in a plumber if the leak stays active

Does the water keep coming, is the damp patch growing or do you suspect a burst pipe? Then quick help is sensible. Klusbedrijf MSZ helps with leaks and pipework in Almere and the surrounding area and is available 24/7 for urgent situations.

How do you recognise a hidden leak?

Not every leak is immediately visible. Sometimes you only notice after a long time that moisture is escaping somewhere. Look out for, among other things:

• damp rings on the ceiling or wall;
• plaster, wallpaper or paint coming loose;
• a musty smell;
• mould;
• a floor that lifts or discolours;
• unexplained water use;
• a central heating system that regularly loses pressure;
• dripping or running sounds while all the taps are closed.

A hidden leak is not always at the spot of the visible damp patch. Water can run along pipes, joists and structural parts before it becomes visible. That is why measuring and a targeted investigation are often more important than just looking at the wettest spot.

Leaks from a water pipe

With a leaking water pipe you sometimes see water straight away, but a pipe in a floor or wall can leak unnoticed for much longer. Depending on the situation, a pipe can be repaired, replaced or rerouted.

You can find more information about repairs and installation on our page about leaks and pipework.

Leaks from the roof

A damp patch on the top floor is not always caused by a water pipe. Especially after rain or strong wind, the cause may be on the roof, for example at damaged roof tiles, joints, bitumen or roof penetrations.

If the leak mainly appears during or after rain, also take a look at our information on roofing in Almere.

What does it cost to fix a leak?

The costs depend on the cause, accessibility and the repair needed. A visibly leaking coupling can usually be fixed faster than a hidden leak that needs investigating first.

Would you like to know beforehand how Klusbedrijf MSZ charges for the work? Then see our current prices. You can also send a photo and a short description first, so the situation can be assessed better.

Can a small leak wait?

That is usually not wise. A small leak can let moisture soak into the structure and so cause more damage than is visible at first sight. Long-term damp can also lead to mould, damage to finishes and problems with wood or insulation.

If you are not sure whether it is condensation, a leaking pipe or a structural problem, it is wise to have the situation checked before you paint, plaster or refinish.

When do you need leak detection?

Leak detection is particularly useful when there are clear signs of damp, but the source is not visible. Think of a damp patch without a visible pipe, recurring pressure loss or a leak under a floor.

The aim is to locate the source as precisely as possible. Read more about our approach on the page leak detection in Almere.
