A water leak at home requires quick action to minimize damage. Immediately turn off the main tap, move valuables away from the water area, and contact a plumber urgently if the leak is extensive. Document the damage with photos for insurance purposes and wipe up as much water as possible. Quick action prevents expensive consequential damage such as moisture and mold.
What should you do first when you discover a water leak in your home?
When you discover a water leak in your home, the first thing you should do is turn off the main tap. The main tap is usually located in the basement, under the sink, or by the water meter. By stopping the water supply, you prevent more water from flowing out and making the situation worse.
Then remove all valuables, furniture, and electronics from the affected area. Take photos of the damage before you start cleaning—you will need these for your insurance claim. Start mopping up the water with towels, a floor mop, or a wet vacuum to prevent the water from spreading to other rooms.
Contact your insurance company as soon as possible to report the damage. In the event of extensive water leakage or if you cannot locate the source, call a plumber immediately. Ventilate the area well by opening windows and turning on fans to prevent moisture problems.
Where do water leaks most often occur in the home?
The most common sources of water leaks in the home are pipes under the sink, toilets, washing machines, and water heaters. These areas are subject to constant water pressure and temperature changes, making the connections particularly susceptible to wear and tear over time.
Under the sink, connections to cold and hot water pipes are common leak points. Washing machines and dishwashers have flexible water hoses that can crack or come loose from their connections. Water heaters often develop leaks from safety valves or from the tank itself when it starts to rust through.
Toilets often leak from the connection between the seat and the drain pipe, or from the internal mechanism in the flush cistern. Radiators and their valves are also vulnerable, especially during the heating season when the system is working hard. Concealed pipework in walls can be the most difficult to detect but often gives signs through damp patches or moldy smells.
How can you temporarily stop a water leak before help arrives?
To temporarily stop water leaks, you can use waterproof tape or sealants available at hardware stores. First, clean the area around the leak of any dirt and dry it completely—sealants do not adhere to wet surfaces.
Use special tape for pipes that is designed for wet environments. Wrap the tape tightly around the leak area, overlapping each turn by half the width of the tape. For larger leaks, you can use quick-drying sealants or temporary pipe clamps available at hardware stores.
Turn off individual taps and valves if the leak is coming from specific fixtures. If the leak is coming from the toilet flush mechanism, you can turn off the water to the toilet via the valve behind the seat. Avoid using silicone or permanent sealants as a temporary solution – this will make professional repairs more difficult later on.
What damage can water leaks cause and how can they be prevented?
Water leaks can cause extensive moisture damage and mold growth, which affects both the structure of the building and your health. Water that penetrates walls, floors, and ceilings creates ideal conditions for mold growth within 24-48 hours.
Structural damage occurs when water affects building materials such as plaster, wood, and insulation. Parquet flooring can warp, laminate can swell, and wallpaper can peel off. Electronic equipment and furniture can suffer permanent damage if exposed to water.
Preventive measures include regular inspection of water pipes, especially under sinks and behind toilets. Replace old water hoses for washing machines and dishwashers every five years. Install water alarms in vulnerable areas such as basements and laundry rooms. Make sure everyone in the household knows where the main water shut-off valve is located so that the water can be turned off quickly in an emergency.
When should you contact a professional plumber in the event of a water leak?
Contact a professional plumber immediately in the event of extensive water leakage that you cannot stop yourself, when the source of the leak is unknown, or when the water is coming from hidden pipes in walls or ceilings. Professional help is also needed for recurring leakage problems that indicate underlying system faults.
Complex repairs that require replacement of pipe fittings, connections to the main water supply, or work on the drainage system should always be carried out by qualified plumbers. They have the right tools and knowledge to identify the root cause and carry out lasting repairs.
Emergency situations that require immediate professional assistance include water leaks from water heaters, burst main water pipes, or water flowing through the ceiling from the floor above. Do not delay in calling—the faster the action, the less the total damage and repair costs will be.

Frequently Asked Questions
How long can temporary sealing solutions be used before permanent repair is required?
Temporary seals with waterproof tape or quick-drying compounds should only be used for 24-48 hours as an emergency solution. These solutions are not designed for long-term use and may fail under water pressure. Schedule professional repair as soon as possible to avoid the problem worsening and causing greater damage.
How much does it usually cost to repair different types of water leaks?
The cost varies depending on the extent and location of the leak. Simple repairs such as replacing a tap or seal often cost SEK 1,500-3,000, while extensive pipe replacements can cost SEK 5,000-15,000 or more. Emergency call-outs outside office hours often incur an additional charge of SEK 500-1,500. Always request a cost estimate before work begins.
How can you tell if the water leak has caused hidden moisture damage in the walls?
Signs of hidden moisture damage include moldy odors, moisture stains on walls or ceilings, peeling paint or wallpaper, and fungal growth on wooden elements. Use a moisture meter to check the moisture content of walls—values above 15-20% indicate a problem. If hidden moisture damage is suspected, a moisture expert should be contacted for a professional assessment and action plan.
What insurance policies cover damage caused by water leaks, and what is required to receive compensation?
Home insurance usually covers sudden and unforeseen water leaks, but not damage caused by poor maintenance or slow leaks. To receive compensation, you must report the damage immediately, provide photographic documentation of the damage, and prove that you have taken reasonable measures to limit the damage. Keep all receipts for repairs and rescue work.
How often should you inspect your home to prevent water leaks?
Conduct a thorough plumbing inspection at least twice a year, preferably in the spring and fall. Check the water hoses to the washing machine and dishwasher monthly, and replace them every 5 years. Inspect under sinks, around toilets, and near the water heater every month. Install water alarms in risk areas for early detection of leaks.
What should you do if the water leak comes from the neighbor above you in a condominium?
Contact your housing association and the neighbor above immediately to inform them of the situation. Turn off the electricity in the affected areas for safety reasons and document the damage with photos. Report the damage to your home insurance company, but also inform them that the source is your neighbor's apartment. The housing association is often responsible for coordinating repairs between apartments and handling insurance matters.
