When homeowners think about home improvements, updates to kitchens, bathrooms and new flooring often top the list. Yet many of the upgrades that do the most to protect a home’s long-term value are far less visible.

Across Canada, extreme weather events are becoming more frequent and costly. Intense rainfall, flooding, prolonged heat waves, wildfire smoke and severe winter storms are placing increasing pressure on homes and the systems designed to protect them. According to the Insurance Bureau of Canada (IBC), insured losses from severe weather have reached record levels in recent years, with water damage now representing one of the leading causes of home insurance claims.

The encouraging news is that improving a home’s resilience does not necessarily require major renovations. Many of the most effective upgrades are relatively affordable, can be completed over a weekend and provide year-round benefits through improved energy efficiency, lower utility costs and reduced maintenance.

Here are several practical ways to make your home better prepared for whatever the seasons bring.

Protect your home against water damage

Water is responsible for some of the most expensive and disruptive home repairs. While river flooding often receives the most attention, many claims result from heavy rainfall overwhelming drainage systems, sewer backups or water pooling around a home’s foundation.

Improve drainage around your home

The ground surrounding your home should slope away from the foundation to direct rainwater away from the structure. During a heavy rainfall, take a walk around your property to see whether water collects near foundation walls or flows away as intended.

Downspouts should discharge water at least two metres from the home’s foundation. Installing inexpensive downspout extensions can significantly reduce the risk of basement leaks and foundation damage.

Keep gutters and eavestroughs clear

Leaves and debris can prevent gutters from draining properly, causing water to overflow and run down exterior walls or collect near the foundation. Cleaning gutters in the spring and fall is one of the simplest maintenance tasks homeowners can perform to help prevent costly repairs.

Install a backwater valve

A backwater valve helps prevent sewage from flowing back into your home during periods of heavy rainfall when municipal sewer systems become overwhelmed. Many municipalities offer rebate programs to help offset installation costs, and some insurers may provide premium discounts for homes equipped with one.

Ensure your sump pump is ready

If your home has a sump pump, test it regularly and consider installing a battery backup. Power outages often accompany major storms, making a backup power source essential when it is needed most.

Water leak sensors are another worthwhile investment. These inexpensive devices can alert homeowners to leaking appliances or burst pipes before significant damage occurs.

Prepare your home for hotter summers

Canadian homes have traditionally been designed to retain heat during long winters. As heat waves become more frequent, many homes, particularly older ones, struggle to stay cool.

Consider a heat pump

Modern cold-climate heat pumps provide highly efficient heating during winter while also functioning as air conditioners during the summer. In many cases, they consume less energy than traditional heating and cooling systems, helping reduce utility costs while improving comfort year-round.

Various federal, provincial and utility incentive programs may help offset installation costs, although available rebates differ by region and change over time.

Reduce heat before it enters the home

Exterior shading is significantly more effective than interior blinds or curtains because it blocks sunlight before it reaches the windows.

Options include:

  • Awnings
  • Exterior shutters
  • Shade sails
  • Pergolas
  • Strategically planted deciduous trees, which provide shade in summer while allowing sunlight through during winter after their leaves have fallen

Improve insulation and air sealing

Well-insulated homes stay warmer during winter and cooler during summer. Sealing air leaks around windows, doors, attic hatches and electrical penetrations not only improves comfort but can also reduce heating and cooling costs throughout the year.

Improve indoor air quality during wildfire season

Wildfire smoke can travel hundreds or even thousands of kilometres, affecting communities far from active fires. Fine particulate matter can enter homes through small gaps and significantly reduce indoor air quality.

Upgrade your furnace filter

Homes with forced-air heating or cooling systems can improve indoor air quality by installing a higher-efficiency furnace filter, such as one with a higher MERV rating that is compatible with the HVAC system. Running the system’s fan continuously during smoky conditions can help circulate and filter indoor air.

Always confirm the maximum filter rating recommended by the equipment manufacturer to avoid restricting airflow.

Create a clean-air room

A portable HEPA air purifier can substantially reduce airborne smoke particles inside a single room. Bedrooms are often the best location, as people typically spend the longest uninterrupted period there.

Seal air leaks

Replacing worn weatherstripping and sealing gaps around windows and doors can reduce smoke infiltration while also improving energy efficiency throughout the year.

Reduce wildfire risk around your property

Research has shown that many homes lost during wildfires are ignited not by a wall of flames but by wind-blown embers that land on combustible materials close to the structure.

Creating a non-combustible zone around your home can significantly reduce this risk.

Focus on the area closest to the house

Within approximately 1.5 metres of the home:

  • Remove dry leaves and pine needles
  • Keep firewood well away from exterior walls
  • Avoid combustible mulch directly beside the home
  • Trim shrubs that touch siding or windows
  • Regularly clear roofs and gutters of debris

Protect vulnerable openings

Install fine metal mesh screens over attic, soffit and foundation vents to help prevent embers from entering the home.

Choose resilient materials during renovations

When replacing roofing, siding, fencing or decking, consider fire-resistant or non-combustible materials where practical. Selecting these products during scheduled renovations often adds relatively little to the overall project cost while improving long-term resilience.

FireSmart Canada provides free assessment tools and practical guidance for homeowners interested in reducing wildfire risk.

Prepare for severe winter weather

While summer weather receives increasing attention, winter storms remain a significant source of property damage across Canada.

Simple seasonal maintenance can help reduce risk:

  • Disconnect and drain outdoor hoses before freezing temperatures arrive.
  • Know where your home’s main water shut-off valve is located.
  • Insulate exposed water pipes in unheated areas.
  • Trim dead or overhanging tree branches that could fail under snow or ice.
  • Keep enough emergency supplies on hand to remain comfortable during a prolonged power outage.

Review your insurance coverage regularly

Physical improvements are only one part of protecting your home. Equally important is ensuring your insurance coverage reflects today’s risks.

Many homeowners are surprised to learn that overland flood coverage and sewer backup coverage are often optional endorsements rather than standard features of a home insurance policy. Availability can also vary depending on location and local flood risk.

Your insurance broker can explain:

  • What perils are currently covered
  • Whether additional endorsements are available
  • Applicable deductibles and coverage limits
  • Whether certain mitigation measures qualify for premium discounts

Some insurers offer incentives for features such as monitored water leak sensors, battery-backed sump pumps, backwater valves or homes that have completed FireSmart mitigation work.

Small improvements can make a significant difference

Improving a home’s resilience does not require tackling every project at once. Regular maintenance and incremental upgrades often provide the greatest long-term value.

Cleaning gutters, extending downspouts, testing the sump pump and reviewing your insurance coverage are straightforward tasks that can help reduce the likelihood of some of the most common and costly home insurance claims.

As major components of your home eventually require replacement, choosing more resilient materials and systems can further strengthen your home’s ability to withstand increasingly unpredictable weather while improving comfort, efficiency and long-term peace of mind.
