Common Causes of Basement Flooding in Ontario Homes

Basement flooding is a big issue for many homeowners in Ontario homes. Basement flooding can occur due to rain, snowmelt, spring thaw, or storms. Water might enter your basement quickly by means of a sewer backup or broken pipe, or slowly as a result of foundation cracks, improper drainage or faulty sump pump. Whatever the cause, even a little bit of water can ruin carpets, floor, drywall, insulation, furniture, appliances, and other items in the home.

It will be helpful for Ontario homeowners to know the common causes of basement flooding as it may help to prevent any damages from occurring. Regular maintenance, proper drainage system outside the home, plumbing inspection, and working water control devices will greatly decrease the risk of flooding. If the water enters your home, you need to extract and dry it out immediately. Railway City Carpet Cleaning offers professional water extraction services for Ontario homes in St. Thomas, London, Tillsonburg, Ingersoll, Aylmer and the surrounding areas.

Heavy Rainfall and Severe Storms

Excessive rainfall is a significant contributor to flooding of the basements in Ontario. In storms that bring a lot of rainfall, the soil around the house becomes saturated very fast. Once the ground can no longer absorb any water, it becomes easier for the rainwater to accumulate around the foundation and enter through the cracks or any openings such as window wells and basement doors.

The drainage system that is old may not be able to cope with heavy rainfall. If the municipal sewer system becomes flooded with water, then the water may find its way into the house through the basement drains, toilets, and plumbing fixtures. This can be dangerous for homes that are situated in low lying areas and homes with poor drainage systems.

It is important that homeowners check their downspouts, gutters, and window wells and make sure that there is enough drainage around their home.

Rapid Snowmelt and Spring Thaw

Water Collecting Around the Foundation

In Ontario, winter months are likely to have a lot of snow which will eventually be succeeded by warm weather in early spring. With rapid melting of snow while the ground is still frozen, the water will be unable to drain into the ground, and thus melting snow will be collected around the house putting pressure on the foundation.

If the water is not drained out, it will get into the house through cracks in the foundation, windows on the basement level, gaps where the walls meet, and even gaps along the utility line. Those homes that are poorly graded are most likely to be affected since melting snow is automatically drawn towards the building.

The snow should be removed from the vicinity of the foundation and any downspouts should be clear.

Ice Blocking Exterior Drainage

Ice buildup can occur in gutters, downspouts, window well drains, and other exterior drainage channels. As temperature increases, the melting snow and rainwater have no place to go as they cannot drain properly and may cause flooding around the foundation and enter the basement eventually.

This problem can be avoided by making sure that drainage systems are working fine before the arrival of spring.

Poor Property Grading

The ground next to a home is supposed to have a downward slope from the foundation. In cases where the soil is sloped towards the home, water is automatically directed into the basement of the building. The water may be able to accumulate at the foundation point and seep through cracks or other openings.

Over a period of time, soil erosion may occur resulting in low spots next to the house. Other factors, such as landscaping, which are undertaken, may result in directing water flow towards the foundation. A correctly graded property may experience drainage problems after some years due to soil erosion.

Puddles next to the foundation after rainy days may indicate grounding problems on the property.

Clogged or Damaged Gutters and Downspouts

Gutters are supposed to catch water coming off the roof and funnel it into the downspouts. If the gutters are full of leaves, dirt, ice, or other debris, the water could spill out and flow right next to the foundation. Broken or disconnected downspouts will have the same effect.

When downspouts run too close to the house, water will flow out near the basement walls. Over time, this water can make the soil soft around the basement and cause it to be subjected to increased pressure and possibly lead to leaks in the basement.

Gutters need to be cleaned on a regular basis, particularly during autumn and after heavy rains. Extensions on the downspouts can move the water further away from the building.

Foundation Cracks and Wall Leaks

There is a possibility that concrete foundations will form cracks as the house settles

down or as the temperature fluctuates. Some of these cracks might be tiny and harmless while others might allow water to flow into the basement when there is rainfall or thawing of snow.

Water might even find its way into the basement through the gap that is formed at the intersection between the basement wall and the floor. Such gaps are created when there is an increase in the hydrostatic pressure around the foundation walls.

It is advisable to inspect any cracks on your foundation and not try to cover them up with paints or any other sealing materials.

Sump Pump Failure

The sump pump gathers water around the house foundation and transfers it away from the structure safely. As long as everything functions well, the pump will protect your basement during the rainy season, melting snow, and high levels of water on the ground surface. A failed sump pump causes water to rise fast within the sump pit to the basement.

There are many ways in which a sump pump could fail. These include lack of power

supply to the device, clogged discharge line, float switch damage, mechanical problems, poor maintenance, and wrong sizing for the amount of water coming into the structure. 

Testing the sump pump for proper operation involves introducing water into the sump pit and seeing whether the device kicks into action. You also need to check the discharge line to see how far the water is discharged.

Burst, Frozen, or Leaking Pipes

The low temperature in Ontario during winter leads to the problem of frozen pipes. This is because the ice created when water freezes expands hence creating high pressure which may cause the pipe to burst and spill the water.

Water pipes located in the basement, attic, garage, outside walls, and utility rooms are most susceptible to freezing. Water leaks may not be immediately noticed especially if they are in hidden areas like inside walls, under the floor, or inside storerooms.

It is important to insulate any exposed pipes, seal off any holes for cold air, and maintain steady temperatures indoors. It is also advisable for homeowners to know where the main water shut-off valve is located.

Leaking Water Heaters and Appliances

Basements usually have heaters, washing machines, utility sinks and other such appliances connected to the water lines. Leaks from damaged hoses, loose connections, cracked tanks or clogged drains can spill water all over the floor of the basement.

Heaters and water tanks can suffer from rust and small leaks before their tanks break. Washing machine hoses could wear out with time and start leaking without any prior notice. Inspection will be useful in spotting signs of rusting, wetness, bulged hoses and other similar problems.

High Groundwater Levels

In some areas of Ontario, the construction of houses takes place in regions with a high level of groundwater naturally. When there is heavy rain or snow melting, the groundwater can rise up due to its pressure on the foundation of the building. The pressure will result in water leaking from the walls and basement floors.

There might be a problem in homes that have weeping tiles that are broken or foundation drainage that is inadequate. The weeping tiles work by collecting the groundwater in the region of the foundation and directing it either to the sump pump or any other drainage outlet.

Protecting Your Ontario Home From Basement Flooding

To ensure protection against basement floods, it will be necessary to carry out inspection on both the outside and inside of the property. Gutters will have to be cleaned, downspouts extended, any cracks on the foundation fixed, sump pumps will need to be checked and all plumbing systems inspected. The property should be properly graded, so that the water flows away from the house, while basement drains and backwater valves should be kept open.

In case of any flood, standing water will need to be removed immediately when it is safe. This is because moisture has a tendency to spread through floors, carpeting, walls, and behind baseboards. If you experience a basement flood due to storms, melting snow, plumbing leakage, sewer backflow or any other type of flooding, Railway City Carpet Cleaning will be happy to help.

Conclusion

Basement flooding is one of the most common and costly problems faced by Ontario homeowners, but many of its causes can be prevented through regular maintenance and early intervention. Heavy rainfall, rapid snowmelt, poor drainage, foundation cracks, sump pump failure, plumbing leaks, and high groundwater levels can all allow water to enter your home and cause significant structural damage and mould growth.

By inspecting your property regularly, maintaining drainage systems, and addressing potential issues before they become major problems, you can greatly reduce the risk of basement flooding. If flooding does occur, immediate water extraction and professional drying are essential to minimize damage and restore your property safely.
