Your house is a complex structure. Inside, there are several mini-systems that must run efficiently to ensure that you and your family are in a conducive and healthy living environment.
When some of these mini-systems, especially those that require water to operate are not functioning properly, problems are likely to occur.
what are the top 6 most common causes of water damage in your house?
The top 6 most common causes of water damage in your house are:
Issues with the plumbing system including old plumbing and broken pipes.
Leaks from malfunctioning or faulty household appliances such as water heaters and washing machines.
Accidents involving water- example, overflowing bathtubs.
Humidity build-up which allows water to collect in some areas such as crawl spaces, basements and attics. This happens over a long time but is very common either way.
Issues with the Heating, ventilating and air conditioning systems (HVACs) in your home.

Internal & External Causes of House Water Damage
In general, the causes of water damage to your house can be divided into two broad categories based on their place of origin. Internal and external.
The internal causes of house water damage come from inside your household. Malfunctioning household appliances fit perfectly into this category.
On the other hand, the external causes of house water damage, originate from the outside of your house. A good example of this is floods.
It is important to note that: even though external causes originate from outside your house, the resultant damages are felt and seen inside your home.
Within these 2 broad categories of water damage, there are several sub-categories as shown, on the table, below.
Internal causes of water damage
External causes of water damage
1. Issues with plumbing system
1. Natural disasters/ Weather-related causes such as floods
2. Malfunctioning appliances around the house
2. Structural damage to your house- those that result from how your house is structured on the outside example flat roofs, gutters
3. Accidents involving water inside your home
4. Sewer back-up
5. Water collected in basements, attics and crawl-spaces
6. issues with the Heating, ventilating and air conditioning systems
Internal Causes of House Water Damage
As explained above, these causes of water damage come from inside your house.
If you are to avoid water damages to your house, you must pay close attention to this section. Because, this is where most of your control, if not all of it, lies.
If the source/cause of water damage comes from inside your house, you can easily identify it and stop it.
There are 6 sub-categories under this broad category. And, it is evident that all the top 6 most common causes of water damage mentioned above fall under this broad category.
Sub-categories of Internal Causes of Water Damage
Issues with the plumbing system
This is the number one reason you are likely to face water damage in your home.
Your plumbing system experiences wear and tear over time, increasing its susceptibility to clogs, stoppages and breaks. Temperature fluctuations can also lead to broken pipes creating major issues with your plumbing system.
As a result, water leaks from pipes in your bathroom, kitchen and other areas of your home.
Often, water leaks from damaged or broken pipes result into severe water damages inside your house since they can easily go unnoticed.
Because, the signs of the damage caused by water leaks inside your household may take too long to show.
How do you identify issues with your plumbing system early enough?
There are 3 ways to do this;
From your taps– check if the pressure of the water coming from your taps seems too low or if the water is discolored and appears yellowish or brown.
Monitor your water bill– a sudden spike in your billing may indicate the presence of a leak in your plumbing system. Addressing the issue is important before additional damages occur to your flooring, landscaping, foundation as well as other parts of your home.
Using leak detection systems– There are 2 major types of leak detection systems you can use to spot leaking pipes in your home. Passive and active leak detection systems.
The passive systems of leak detection are relatively cheap and easy to use as they sound an alarm whenever they sense the onset of a leak.
The active ones, on the other hand, are a bit more expensive. However, in addition to sounding an alarm when there is a leak, they act to contain and stop it on its own. This saves money as well as the energy needed to respond to the leak.
Prevention and control:
If you spot or suspect that there is a leak in your plumbing system, first, turn off the main water supply valve of your house to contain the leak. This will minimize the damage and buy you enough time to locate the leak and deal with it.
Perform regular visual inspections to check for any leakages in different areas of your home where pipes are located. This includes the area under your kitchen sink, in your bathroom as well as your toilet.
Pipes located in your basement and at the exterior of your house are prone to very low temperatures hence freezing especially during the winter months. Ensure that they are all well insulated before the winter months set in.
Malfunctioning or faulty appliances around your house
All appliances that use gaskets, filters, tubes or pipes to operate are potential sources of water damage in your house.
Due to aging, the pipes of these appliances start to rust, crack and their hoses may weaken causing leakage that leads to extensive water damages in your house.
Although all appliances can cause leakage and damage to your house, you should keep a close eye on your washing machines, hot water tanks and dishwashers.
Because, the 3 are known to cause water damage in your house most frequently.
Prevention and control:
Inspect and maintain your appliances regularly. In case you notice any signs of moisture, rust, bulges or cracks on any of your appliances, take the necessary steps to repair so as to avoid further damages.
Replace your washing machine’s old water supply lines with better ones. You may use the ones made of braided stainless steel instead of rubber because they last longer and do not burst easily when subjected to constant pressure.
Re-caulk and re-seal your bathtubs and showers, from time to time, to minimize the occurrence of water leakages in your house.
Accidents involving water in your house
When you leave taps open or fail to close them properly because you are in a hurry to leave the house for one reason or another, you create a potential source of water damage.
Overflowing bathtubs and sinks are a common cause of property loss due to water damage in your house.
Water over-flows can, literally, seep into any part of your home and cause serious damages that are expensive to repair.
Prevention and control:
Ensure all taps are closed properly- at all times.
Turn the water to the house off if you will be away for more than 24 hours. This will ensure that you prevent any extensive water damage that may occur as a result of leaks springing up in your absence.
Sewer lines may get backed-up due to heavy rainfall or blockage.
Often, tree roots also invade and clog-up drain lines causing blockage. As a result, dangerous contaminants spread very fast creating an unhealthy environment for you and your loved ones.
It is important to note that water from sewers is considered black water which is highly contaminated and harmful to your health.
As noted before,
Water damage to your house, resulting from sewer back-up, falls under a category 3 water damage. And, since backed-up sewers are a health hazard, the damages they cause are best handled by certified professionals.
Humidity build-up in areas that are prone to collect water over time. Such areas include basements, attics and crawl spaces.
Humidity build-up takes place after some time because of aging and hydrostatic pressure.
Water collects in the basements, crawl spaces and attics leading to overall structural damage from severe mold growth and rotting.
Prevention and control:
Install a dehumidifier. It will help to reduce as well as maintain levels of humidity in this areas hence prevent its build-up.
However, in case water has already collected in large amounts, you should apply a different process which involves proper water removal.
Consider contacting home inspectors to get an accurate assessment of the amount of water and extent of damage that has taken place.
Once you have received the home inspector’s report, then, and only then, should you contact a water removal/ water proofing expert to help with the water damage clean-up.
Also, ensure you get more than one quote, preferably 3, from the water removal expert for comparison purposes.
Issues with the HVACs.
This is the Heating, ventilating & air-conditioning system in your home. It is installed inside your house and can hold large amounts of water to be directed outside.
The air conditioner pulls humidity from the air and condenses it into moisture. Then, it (the AC) directs the water into an overflow pan to the outside of the house via the condensate line.
If the overflow pan or the condensate line is damaged and not working properly, moisture builds up within the AC. Over time, the moisture soaks up your ceiling, ruining your drywall as well as flooring.
To add, the moisture can mix with mold spores within the AC’s ducts promoting mold growth.
Prevention and control:
Ensure that your HVAC system is serviced regularly- at least once annually. This will help you notice any potential damages that are likely to occur on the system in good time. And, you can then apply proper mitigation measures.
External Causes of House Water Damage
The external causes of water damage originate from the outside of your house. But, their damaging effects are seen and felt inside your home.
Most, if not all of them, are weather- related. And, even though you might have very little to no control over these causes, you can control how ready and prepared you are for them.
By applying the necessary preventative measures, on a regular basis, to minimize the effects of such damages if they occur.
Sub-categories of External Causes of Water Damage
Natural disasters are part and parcel of our daily lives. Rivers overflow, hurricanes and flash floods strike from time to time. Such disasters cause destructive floods that can lead to water damages commonly referred to as flood damage in your house.
Due to the unpredictability of natural disasters, damages from flood waters to your household are extensive.
I mean if hurricanes can cause entire cities to flood- yes, the whole city. Can you imagine the water damage that takes place to the inside of your home?
Natural disasters cause massive property loss. They might destroy your home to the point it becomes inhabitable or unusable until major repairs are done.
The high level of destruction by natural disasters renders flood water damage repairs very expensive. In fact, if you are not careful, you might end up spending a good chunk of your savings handling the repairs.
Pay prompt attention to such disasters by contacting water removal experts as soon as possible afterwards. It will help reduce the time for severe water damage to occur. This will make the work of the water removal experts a lot easier and save you a lot of money too.
Prevention and control:
Install doors and windows which are highly resistant to heavy rains and other forms of natural disasters. Ensure that you apply all the precautionary measures as outlined by the local regulations.
Store your sensitive electronic equipment and files at high levels inside your house. This is something you can do, ahead of time, to keep the overall water damage to your house minimal should any water-related natural disaster take place.
Consider carrying out a risk assessment to determine the level of risk of flood damage that your home is in. You might find that you live in a moderate to high-risk area. Meaning, the area you live in is prone to flooding, consider purchasing flood insurance.
Please note: water damages as a result of the external causes explained above can be very harmful to your health. It is, therefore, important that you seek professional help as soon as they occur.
Structural damage to your house’s roof, gutters and entire foundation is a very common external cause of water damage.
It is rarely talked about despite being one of the top causes of water leaks that damage your house’s interior.
Normally, roofs have a slight gradient/slope that enables them to direct rain water into your gutters. Over time, the slight slope may fill up with debris including leaves and even branches.
When this happens, the roof becomes flat preventing rain water from being directed into your gutters efficiently. As a result, rain water collects on top of the blocked roof instead of running off it through the gutters.
Standing rain water on top of your roof causes extensive damages inside your house.
How?- In 3 ways:
The weight of the debris and standing water can lead to cracks on your roof. Then the cracks will allow water to leak into your ceiling causing widespread damages in your house.
Mold starts to grow on the roof itself and the ceiling of your home aggressively.
Cold weather also leads to the formation of “ice dams” on your roof. In this case, the roof works well. Water may collect as a small pool on it as usual. But, before it could run off to the ground, the edges of the pool of water freeze creating ice-dams. Standing water from ice dams cause extensive water damages in your house especially on the ceiling.
The gutter system serves to direct water away from your roof. And, from the entire building through the edges.
Water collects and a dam forms on the gutters when this system is not working properly. With time, the water overflows over the gutter’s edges and begins running down the sides of your house. Leading to water damage in the walls of your house.
You can easily notice this form of water damage by looking at your walls. Is the paint peeling off? Can you spot any dirty water marks which are from rainwater that has spilled over from your gutters?
Water damage to your house’s walls also happens when your gutter system is faulty. If your gutter has a hole or crack, water leaks down your building’s side even if there is no heavy rain. Either way, you are likely to face serious water damage in walls of your house.
Additionally, your walls might remain wet constantly and for a long time causing the damage to spread.
In the worst possible case, water that runs down the sides of your gutters might start collecting at the base. At this point, standing water that is building up causes more severe damages due to basement leaks and mold growth.
Prevention and control:
Practice proper regular and seasonal home maintenance to prevent the build-up of debris and other materials on the roofs and gutters. This way, your risk of experiencing water damage as a result of an ineffective gutter system is reduced. And, you can always carry out any repairs should you notice your gutter system is faulty, in good time.
Other common causes of water damage inside and outside your house include:
The toilet runs and eventually drips, ruining your walls and floors.
Your garbage disposal can flood cabinets with dirty water mixed with food garbage. Always check for any leaks on your garbage disposal, from time to time, to prevent this.
The sump pump, which directs water away from your house keeping your crawlspace or basement dry, can stop pumping. When this happens, water begins to build up leading to crawlspace/basement flooding.
Drains can stop draining allowing water to collect at different parts of your home. A blocked floor drain, for example, results in your basement filling up with water. You can open up clogged drains easily using air blasters, plumbing snakes or plungers.
Fire sprinkler systems can freeze and burst during the winter months if you do not perform regular winter maintenance. Proper sprinkler maintenance routines especially during cold weather prevents the system from bursting. And, helps you avoid water damage in your house.
Water damage in your house is a common occurence. And, by now, you can clearly tell that household water damage is something you are likely to face not once but severally. You will definitely need the services of a certified water damage restoration expert at some point since you cannot completely eliminate all the risk of experiencing water damage. And, DIY solutions cannot be applied to all forms or types of water damage.
Remember: you always have a choice to take all the necessary preventive measures in good time. This will reduce your risk/ chances of facing water damage inside your home. And, help you respond appropriately should you notice any potential sources of damage.
