So, you’ve noticed a crack in the basement. Or maybe the front door has started putting up a fight every time you try to leave the house. Your mind probably goes straight to the worst-case scenario: a total foundation collapse and a bill that looks like a phone number.
Take a breath.
At Foundation Pros of Winnipeg. we have spent years under houses across Southern Manitoba and Western Ontario, from family bungalows in Transcona to lakeside cottages out at Lake of the Woods. If there’s one thing I’ve learned, it’s that your house talks to you long before it screams for help. You just need to know how to listen.
In this chapter of our guide, “How to Save Your Foundation,” I’m going to give you the tools to perform your own “DIY Health Check.” Think of this as a triage for your home. We’re going to separate the “don’t worry about it” from the “get Lloyd on the phone right now.”
The Sticky Door Test: Humidity or Foundation?
In Winnipeg, we blame everything on the weather. If it’s 35 degrees with 90% humidity in July, your wooden doors are going to swell. That’s just physics. But how do you know if that sticky door is a seasonal annoyance or a sign that your foundation is doing the “Winnipeg Lean”?
The Humidity Check: If a door sticks only during the humid summer months but swings freely in the dead of winter, it’s likely just the wood reacting to moisture.
The Foundation Check: If the door sticks regardless of the season, or if you notice a gap at the top corner of the door frame that looks like a triangle, you’ve got movement.
Look at the trim around your doors and windows inside the house. Are the mitered corners pulling apart? Is there a crack running diagonally from the corner of the door frame toward the ceiling? If yes, your foundation is likely settling or heaving, pulling the frame out of square.

The Nickel Test: Measuring Your Cracks
Not all cracks are created equal. Some are just “shrinkage” cracks from when the concrete was first poured decades ago. Others are structural warnings.
Here is the simplest tool in your arsenal: a nickel.
- Hairline Cracks: If you can’t even fit a fingernail in it, just watch it. Mark the ends with a pencil and write the date. Check it again in six months.
- The Nickel Test: Try to slide a nickel into the crack. If the crack is wide enough to accept a nickel, it’s officially time to stop “watching” and start “acting.” This is a clear sign of active movement or pressure.
- The Step Crack: If you have a concrete block foundation and the crack follows the grout lines in a zigzag (stair-step) pattern, that’s a red flag for settlement.
If you’re seeing these signs, you should check out our guide on whether that crack is actually bad. It’ll help you understand if you’re looking at a simple repair or something more significant.
The Level Test: Bowing Walls and Sloping Floors
In Winnipeg, our heavy clay soil is like a sponge. It expands when wet and shrinks when dry. This exerts massive “lateral pressure” against your basement walls.
Checking for Bowing Walls:
Go into your basement and stand at one end of a long wall. Put your eye right up against the wall and look down the length of it, like you’re sighting a rifle. Does the wall look like it’s “pregnant” in the middle?
If you have a 4-foot level, press it vertically against the wall. If the middle of the wall is touching the level but the top and bottom have gaps, the wall is bowing inward. This is often caused by hydrostatic pressure: water in the soil pushing against your house. Left unchecked, this can lead to a total wall failure.
Checking for Sloping Floors:
We’ve all been in those old Winnipeg homes where a marble dropped in the kitchen ends up in the living room. If your floors feel like a funhouse, your teleposts might need adjusting, or your footings might be sinking.
Exterior Walk-around: The “Enemy Number One”
Foundation repair is 10% concrete and 90% water management. When I walk a property, I’m looking at how water behaves. You should do the same.
1. The Grading
Your soil should slope away from your foundation. I like to see at least a 6-inch drop over the first 10 feet. If the soil is flat: or worse, sloping toward the house: every rainstorm is essentially a direct attack on your basement.
2. Downspouts
Are your downspouts dumping water right at the corner of your house? This is the #1 cause of foundation issues I see in Southern Manitoba. Extensions should take that water at least 6 to 10 feet away from the foundation. It’s a $20 fix that can save you $20,000.
3. Window Wells
Check your window wells for debris. If they’re full of leaves and dirt, they’ll trap water against your basement windows during the spring melt. You want clear drainage.

The Winnipeg Clay Factor: Why We’re Different
I grew up here. I know this dirt. Winnipeg sits on a former glacial lake bed, which means we have some of the most “expansive” clay in the world. When it rains, the clay grabs that water and grows. When it’s a dry August, the clay shrinks and pulls away from your foundation, leaving gaps for the next rain to fill.
This constant “push and pull” is why so many homes here have issues. We aren’t just fighting gravity; we’re fighting the very ground we stand on. Understanding Winnipeg clay vs. your foundation is the first step to a permanent fix.
The Professional Standard: Weeping Tiles and Drainage
If your DIY check reveals a wet basement or bowing walls, we need to talk about what’s happening underground. At Foundation Pros of Winnipeg, we believe in doing things once and doing them right.
When we install exterior weeping tile, we don’t just throw it in the dirt. We place the weeping tile exactly at the wall-to-footing connection point. We then layer drainage rock against the foundation wall, starting at grade and tapering down toward the tile. This creates a clear “highway” for water to fall straight down into the pipe and away from your home. We keep the soil against the rock base sloped away, ensuring your yard stays clean and your basement stays dry. No shortcuts, no “messy” rock-to-grade finishes: just engineering that works.
When to Worry vs. When to Watch
Watch if:
- Cracks are thinner than a nickel and don’t change over six months.
- Doors stick only during extreme humidity.
- There’s a small amount of white, powdery “efflorescence” on the concrete (this is just mineral salt, but it’s a sign to keep an eye on moisture).
Worry (and call us) if:
- You can see through a crack to the outside.
- Horizontal cracks appear (these are almost always structural).
- The wall is bowing more than 1/2 an inch.
- Water is actively seeping into the basement during rain or melt.
- You’re noticing “stair-step” cracks in your brickwork or blocks.

The “One-Wall-at-a-Time” Philosophy
I know that the idea of foundation repair is scary. It sounds expensive, and it sounds like your life is going to be turned upside down.
At Foundation Pros of Winnipeg, we don’t believe in high-pressure sales or scaring you into a massive debt you can’t afford. My dad taught me the value of hard work and looking out for your neighbor. That’s why we often recommend a “One-wall-at-a-time” approach. If your north wall is the only one bowing, let’s fix the north wall. We’ll stabilize it, make it safe, and protect your family. We can look at the rest down the road. This makes the cost manageable and the process less overwhelming. (We’ll dive deeper into the finances in Chapter 4!)
Final Thoughts from Lloyd
Your home is likely your biggest investment. It’s where you raise your kids, host Sunday dinners, and find rest after a long day of work. My goal isn’t just to fix concrete; it’s to make sure Winnipeg stays a city of safe, vibrant homes.
If you’ve done your DIY check and something doesn’t feel right, don’t wait for the “big trouble.” I’ve seen small cracks turn into collapsed walls because a homeowner was too intimidated to call.
We offer free, no-pressure estimates. I’ll come out, take a look, and give you the honest truth: as a neighbor and a pro. Whether you’re in a character home in Wolseley or a new build in Sage Creek, we’ve got your back.
