If you live in Oshawa, you already know how unpredictable our weather can be—especially in the spring and fall. One minute it’s sunny, the next minute you’re watching water pool around your foundation. It’s just part of life in Southern Ontario, where rain, snow melt, and older homes can make basement leaks a real problem.
At Jetflo, we’ve helped a lot of homeowners across Oshawa, Durham Region, and beyond deal with basement water issues—and it always starts with one big question:
Do I really need basement waterproofing?
In this post, we’ll walk you through the most common warning signs, explain the differences between interior and exterior waterproofing, and help you figure out what’s right for your home.
💦 Signs Your Basement Might Need Waterproofing
If you’re noticing any of these, it’s a good idea to act sooner rather than later:
- A musty smell that just won’t go away
- Water stains on the floor or lower walls
- White, powdery stuff on the concrete (that’s called efflorescence)
- Cracks in the foundation
- Water pooling near your foundation or in the yard
- Peeling paint, damp drywall, or signs of mold
Even if there’s no visible water, moisture behind walls or under flooring can cause major headaches over time. Catching it early is key.
🧱 Interior vs. Exterior Waterproofing: What’s the Difference?
There’s no one-size-fits-all solution when it comes to waterproofing. That’s why we always start with a proper inspection and come up with a custom plan. But in general, you’ll hear about two main approaches:
Interior Waterproofing
This option works from the inside of your basement. It’s a good fit if your home is getting light leaks, or if your basement is finished and you’re trying to protect it from future damage.
It usually includes:
- A sump pump to move water out fast
- Interior weeping tile systems that direct water to the pump
- Moisture barriers or sealants
- Drainage channels built along the floor perimeter
✅ Less invasive and more budget-friendly
🚫 May not be enough for serious foundation issues
Exterior Waterproofing
This method tackles water at the source—before it gets inside. It involves digging around the foundation to apply a waterproof membrane, fix cracks, and install exterior weeping tile.
It’s the go-to option for:
- Homes with major leaks or cracked foundations
- Older houses in high-risk areas
- Preventing long-term structural issues
✅ Long-term solution with full protection
🚫 More labour-intensive and requires excavation
