When you discover a water leak in your home, it's important to act quickly to limit the damage. Turn off the main water tap immediately, move valuables away from the water, and document the damage with photos. For larger leaks or if the water is coming close to electrical installations, you should contact an emergency plumber right away. We'll help you understand the signs of a water leak, how to respond, and when you need professional help.
What are the first signs of a water leak in the home?
The most common signs of a water leak include visible water stains on walls or ceilings, damp areas around pipes, unusual noises from the water system, and unexplained high water bills. You may also notice a musty smell or see mold growth in damp areas. These signs can be both obvious and subtle, so it pays to be aware.
Water stains often appear as yellowish-brown discolorations on walls, ceilings or floors. Even small stains can indicate a leak that has been going on for a long time. Damp areas around the kitchen counter, under the sink or by the toilet are also clear warning signs that you should not ignore.
An unexpected increase in your water bill is a sign that many people overlook. If your usage suddenly increases without you having changed your usual habits, it could indicate a hidden leak somewhere in the system. Sounds like running water when no taps are open, or dripping behind walls, tell you that something is wrong.
Musty smells and visible mold are also important warning signs . Mold thrives in damp environments and can develop quickly when there is a persistent water leak. This is not only a sign of a water leak, but also a health problem that should be addressed quickly.
What should you do immediately when you discover a water leak?
When you discover a water leak, turn off the main water valve immediately to stop the flow of water. Then, if it is safe to do so, turn off the power to the affected areas. Move valuables and furniture away from the water, use towels or buckets to collect the water, and take photos of the damage for documentation.
The first thing you should do is locate and turn off the main water valve. This will stop the water supply and prevent the leak from getting worse. If you don't know where the main water valve is, you should find it right away before an emergency occurs.
Once the water is shut off, consider whether it is safe to turn off the power. Water and electricity are a dangerous combination, so if the leak is near electrical outlets, wires, or appliances, you should turn off the fuse for that area. If you are in any doubt about whether it is safe, leave it alone and contact a professional.
Move everything you can away from the water to minimize damage. Furniture, carpets, electronics, and personal belongings should be moved to a dry area. Use towels, mops, or buckets to collect as much water as possible while you wait for help.
Take photos of the damage from multiple angles. This is useful documentation for your insurance company and gives the plumber an understanding of the situation if you call to describe the problem. For large water leaks or if the water does not stop when you turn off the faucet, call an emergency plumber immediately.
How do you find the main tap to shut off the water?
The main water valve is usually located in the basement, utility room, under the kitchen sink, or outside the property near the water meter. In apartments, it is often in a cabinet in the bathroom or kitchen. The valve looks like a wheel-shaped valve or a lever that you turn clockwise to close. If the valve is stuck, do not use force, but call a plumber.
In detached houses, the main tap is usually located where the water pipe enters the house. This may be in the basement, a utility room or a storage room. Some older houses have the tap outside, in a sump near the foundation wall or by the water meter on the property.
In apartments and townhouses, you will often find a separate main tap for your unit. It may be under the kitchen sink, in a bathroom cabinet, or in a shared utility room. Check with your landlord or homeowners association if you are unsure where it is.
The main valve can be a wheel-shaped valve that you turn clockwise until it is completely closed, or a ball valve with a lever that you turn 90 degrees. Both types are easy to operate once you know where they are. It pays to check that the valve is working before you have an emergency.
If your faucet is stiff or stuck, it may be because it hasn't been used for a long time. Don't use too much force, as you could damage the valve and make the situation worse. In such cases, it's best to contact an emergency plumber who has the right tools and experience to handle the problem safely.
When should you call a plumber for a water leak?
You should call an emergency plumber immediately if you experience burst pipes, major water leaks, sewer problems, or leaks near electrical systems. These situations can cause serious damage to your home and pose a safety risk. Minor drips from a faucet or a slow drain can often wait until the next business day, but larger problems require immediate attention.
In the case of burst or burst pipes , water often flows uncontrollably and can quickly cause extensive damage to floors, walls and fixtures. This is an emergency situation that requires prompt action from a professional. The same applies if the water does not stop even after you have turned off the main tap.
Leaks near electrical installations are particularly dangerous. Water coming into contact with electrical outlets, fuse boxes or electrical appliances can cause a short circuit, fire or electric shock. In such cases, you should call an emergency plumber and possibly an electrician immediately.
Sewer problems that stop or back up in the house are also emergencies. This can be both unsanitary and harmful to health, and should be handled by a professional who has the right equipment to solve the problem effectively.
Minor problems like a dripping faucet, a slow-running toilet, or a slow drain can often wait until regular business hours. However, you shouldn't put off repairs too long, as small leaks can develop into bigger problems over time. We offer both emergency and scheduled visits, so you get help when you need it.
How can you prevent water leaks in your home?
You can prevent water leaks by regularly inspecting pipes and fittings, protecting pipes from freezing in the winter, maintaining proper water pressure, replacing old hoses and seals, and knowing the age of your plumbing. Periodic inspections by a professional can also detect potential problems before they become serious.
Regularly inspecting exposed pipes under sinks, behind toilets and around water heaters will help you spot small leaks early. Look for moisture, rust, green discoloration or limescale deposits that could indicate something is wrong. Small problems are much easier and cheaper to fix than major damage.
During the winter, it is important to protect pipes from freezing, especially in unheated rooms, basements and at outside taps. Pipes that freeze can burst and cause major water leaks when they thaw. Insulating pipes and letting taps drip slightly during extreme cold can help prevent frost damage.
High water pressure can wear down pipes and fittings over time. If you notice water spurting out of your faucets or making noise when you turn off the water, the pressure may be too high. A plumber can install a pressure regulator to protect your system.
Hoses for dishwashers, washing machines and toilets should be replaced every five to seven years, even if they look good. Rubber and plastic become brittle over time and can burst suddenly. The same goes for gaskets and seals around taps and valves. These small components are cheap to replace, but can prevent major damage.
If the plumbing in your home is over 30 years old, you should consider a professional inspection. Older pipes may have corrosion, limescale, or other problems that aren't visible on the outside. A professional can assess the condition and advise you on maintenance or replacement before problems arise.
Prevention saves you both worry and expense. By being aware and taking proactive steps, you can avoid many of the most common causes of water leaks in your home. We are happy to help you with periodic inspections and maintenance that will keep your water system in good condition.

Frequently Asked Questions
Can I repair a small water leak myself, or do I always have to call a plumber?
Minor leaks, such as a dripping faucet with a worn gasket or a loose fitting under the sink, can often be fixed yourself if you have basic tools and experience. However, if you are unsure of the cause, the leak is in the wall or floor, or the problem involves the main pipes, you should always contact a professional plumber. Improper repairs can make the damage worse and lead to more expensive repairs later.
Does my insurance cover damage from water leaks?
Most home and building insurance policies cover sudden and unexpected water leaks, but not damage caused by poor maintenance or wear and tear over time. It is important to document the damage with photos, contact your insurance company quickly, and have a professional assess the cause. Read the terms of your insurance policy carefully, as coverage may vary between companies.
How can I find a hidden water leak that I can't see?
Hidden leaks can be detected by checking your water meter when no faucets are in use – if the meter is still running, you probably have a leak somewhere. Other signs include damp spots on walls or ceilings, a musty smell, unexplained hot or cold floors, or unexplained high water bills. A plumber can use specialized equipment such as moisture meters, thermal imaging cameras, or listening devices to pinpoint hidden leaks.
What do I do if the water leak happens in the middle of the night or on the weekend?
Immediately turn off the main faucet, turn off the power to the affected areas if safe to do so, and collect the water with towels or buckets. Then call an emergency plumber who offers 24-hour service – many plumbing companies have an emergency hotline. Don’t wait until the next business day if there’s a major leak, as the damage can increase significantly with each passing hour.
How long does it usually take to repair a water leak?
Simple repairs like replacing a gasket or tightening a fitting often take 30 minutes to an hour. More extensive work like repairing a burst pipe in the wall, replacing sections of pipework or fixing hidden leaks can take several hours or even days, depending on availability and the extent of the damage. The plumber will give you an estimate after assessing the situation.
How do I dry up after a water leak to avoid mold and moisture damage?
Remove as much water as possible with mops, towels and a wet/dry vacuum cleaner, and use fans and dehumidifiers to dry the area thoroughly for 24-72 hours. Remove wet carpets, rugs and furniture that cannot be dried quickly, and make sure that hidden areas such as under floors and behind skirting boards are also dry. For large amounts of water or if the water has been standing for a long time, you should consider contacting a professional drying company to avoid long-term moisture problems and mold growth.
Are there any special measures I should take before going on vacation to avoid water leaks?
Turn off the main water tap if you are going to be away for extended periods, especially in winter when the risk of frost increases. Check that all taps are turned off, drain the water heater if there is a risk of frost, and ask a neighbor or friend to check your home regularly. Some people also choose to install smart water leak sensors that will alert you on your phone if problems occur while you are away.
