Why spring gardening and landscaping can become an insurance issue

Spring gardening and landscaping can become an insurance issue. Even small changes to soil, grading, or hard surfaces can alter how water drains in your property. Excess water around your home could overwhelm drainage, increasing risks of basement leaks and water damage, causing insurance claim complications.

Spring is when many Canadians head outside to tackle long-awaited yard projects after a winter cooped up indoors. Maybe you’re adding fresh mulch, building a patio, levelling uneven ground, or finally putting in those raised garden beds you’ve been dreaming about. These updates can improve curb appeal and even increase property value, but they can also create an unexpected problem: changing how water moves around your home.

Rather than landscaping itself, the shift in drainage brings insurance risk. Here’s what homeowners should know before starting spring yard projects. 

How can spring landscaping increase your risk of basement flooding?

Most homeowners think about landscaping in terms of appearance or usability. Insurers and contractors, however, focus on water flow and drainage.

“Grading is probably the easiest way to keep watershed away from your home,” says Chris Matoff, owner of Luxe Landscaping. “So many people have a sunken brick interlock patio, and they don't have the proper slope. Everything's heading in toward the house, and that's just going straight down to your foundation.”

Your yard is designed to move water away from your home’s foundation. Changing the shape, height, or surface of the ground can also change where rainwater and melting snow end up.

Some common spring projects that can unintentionally affect drainage and create insurance risk include:

• Adding garden beds or thick layers of mulch near the foundation
• Raising soil levels to fill in low spots
• Installing patios, interlock, walkways, or retaining walls
• Removing sod, shrubs, or deep-rooted plants that absorb water
• Building raised planters against exterior walls
• Compacting soil with heavy equipment or foot traffic

According to the City of Toronto, proper grading around a home is one of the most important ways to reduce basement flooding risk. Water should always flow away from your foundation, not toward it. 

What is grading and why does it affect basement water damage?

Grading refers to the slope of the ground around your property. Ideally, the soil around your home should gradually slope away from the foundation to help direct water towards proper drainage. Even relatively minor changes can interfere with that design, and have an impact on your insurance.

For example, piling soil or mulch too high against exterior walls can allow moisture to collect near the foundation. Hard surfaces like patios and interlocks may prevent water from soaking naturally into the ground. Compacted soil can also reduce absorption and increase runoff during heavy rainfall.

Over time, these conditions can increase pressure against basement walls or raise the likelihood of water entering through cracks, window wells, or foundation seams.

Homeowners may not notice a problem until a major rainfall or spring thaw exposes it. Matoff says many homeowners ignore drainage problems for years because they only become noticeable during spring thaw, or periods of heavy rain.

“I've had people say they've had a crack in their basement for five years and it only acts up in the springtime when everything starts de-thawing and the rain is coming down like crazy in April,” he says. “But those issues get worse and worse over time. You're actually watching a problem happen slowly right in front of your eyes rather than being proactive.”

He adds that pooling water is often a warning sign homeowners overlook. “If you see a couple inches of water up top on the ground, just imagine what's underneath that,” says Matoff. “It's out of sight, out of mind until it becomes a serious problem.”

Can landscaping changes affect your home insurance claim in Canada?

Water damage claims are one of the most common and expensive home insurance claims in Canada. But not every type of water damage is covered the same way. Many home insurance policies distinguish between:

• Sudden and accidental damage
• Gradual damage or maintenance-related issues

For example, sewer backup coverage may help if water suddenly enters your basement during a storm. However, if an insurer believes poor drainage, altered grading, or ongoing maintenance issues contributed to the damage, the claim process can become more complicated.

Matoff says drainage-related issues are one of the most common problems his company is called to fix. “It could have been sunken interlock, poor positioning of downspouts, or grading problems that slowly pushed an area down or caused water buildup over time. We're always dealing with some form of damage caused by drainage.”

A landscaping change doesn’t automatically void coverage. But adjusters will typically investigate how the water entered the home and whether preventable conditions played a role.

If altered grading redirected water toward your foundation, an insurer may argue that landscaping contributed to the loss. This can result in your insurer denying part of your claim.

This is especially important because overland water and sewer backup coverage are often optional endorsements rather than standard inclusions in a policy.

What do insurance adjusters look for after a water damage claim?

Most homeowners aren’t thinking about insurance when they plant flowers or install a stone pathway. Insurers, however, focus heavily on the mechanics of water movement after a claim occurs.

An adjuster is not judging whether or not your landscaping looks good. They’re trying to determine:

• Where the water came from
• How it reached the basement
• Whether drainage conditions contributed to the damage
• Whether the issue developed suddenly or over time

That investigation may include reviewing grading, soil levels, drainage systems, downspouts, and hardscaping around the home.

Are gardening tools and landscaping equipment covered by insurance?

In many cases, items like lawnmowers, trimmers, leaf blowers, and small gardening tools fall under your contents coverage. That means they may be covered against insured risks such as theft or fire, subject to your policy limits and deductible.

Higher-value landscaping equipment, riding mowers, or specialty tools may have separate limits or exclusions depending on the insurer. It’s worth reviewing your policy to verify your coverage if you’ve recently invested in expensive outdoor equipment.

Some insurers may also place limits on landscaping features themselves, such as trees, shrubs, fencing, or decorative gardens. Coverage for outdoor property is often more limited than reimbursement claims for your home and belongings.

Does landscaping affect wildfire risk and home insurance in Canada?

Drainage is not the only insurance-related concern tied to landscaping. In wildfire-prone areas, insurers and fire experts increasingly encourage homeowners to think carefully about vegetation and yard design near the home.  

Basic maintenance such as trimming trees, clearing dry debris, and keeping combustible plants away from exterior walls can help reduce fire risk.

While wildfire concerns may feel more relevant in western Canada, extreme weather and wildfire exposure are becoming more important across the country. Thoughtful landscaping and home design can support both water management and overall property protection.

How can homeowners prevent drainage-related water damage?

Most spring landscaping projects go smoothly. The problem is that drainage issues are often invisible until the next heavy rainfall or major snowmelt.  

Before starting major yard work, think beyond appearance alone. Pay attention to how water currently moves around your property and avoid changing grading near the foundation unless you fully understand the impact.

A few practical tips include:

• Keep soil and mulch below siding and foundation lines
• Extend downspouts away from home
• Avoid sloping patios or walkways toward the house
• Be cautious when adding raised beds near exterior walls
• Preserve original grading whenever possible
• Consult a landscaping or drainage professional for larger projects

“Grading should definitely be the most important step, even if it's just doing a normal dirt slope,” says Matoff. “That alone can change foundation drainage issues tremendously.”

While drainage repairs can be expensive, Matoff says delaying them often leads to far bigger structural problems later. “It's a sizeable investment, but in the grand scheme of home ownership, spending a few thousand dollars now can prevent spending tens of thousands later,” he says. “Spend a little bit now or spend a lot later.”

When it comes to basement water damage, small changes outside the home can sometimes lead to expensive problems inside it. And if a future insurance claim depends on how water got there in the first place, those landscaping decisions may matter more than you expect.
