Professional Basement Waterproofing in Aurora
If your basement has that musty smell that won’t quit, or you’ve spotted a damp wall you keep meaning to look into, you’re dealing with something a lot of Aurora homeowners run into. It’s more common than people think, and it’s rarely as complicated to fix as it seems. At J.M WaterProofing, we handle these basements all the time, and we know how to get to the real cause instead of just masking it.
We’ve worked on homes all over Aurora, from the heritage properties around the historic downtown to the newer builds near Bayview and Wellington. Every home is a little different, but the goal is always the same: a basement that stays dry, year after year.
Why Basements in Aurora Give Homeowners Trouble
Aurora sits close to the Oak Ridges Moraine, which affects how water moves through the ground here. Combine that with clay-heavy soil that doesn’t drain well, and you’ve got water sitting right up against your foundation instead of running off. Older homes in the downtown core face extra strain too, since many foundations were built decades before modern waterproofing standards existed.
A few things we see again and again:
- Clay soil that holds water instead of letting it drain
- Older foundations that were never properly waterproofed to begin with
- Cracks in the walls or floor, sometimes too small to notice right away
- Grading around the house that pushes water toward the foundation instead of away
- Weeping tile that’s aged out, clogged, or missing altogether in older homes
Signs It's Time to Get a Basement Checked Out
Some basements show obvious signs, others just feel off. Here’s what to keep an eye on:
- A musty smell that sticks around no matter how much you clean
- Walls that feel damp or cold to the touch
- White, chalky residue on concrete (called efflorescence, and it means water is passing through)
- Paint bubbling or drywall going soft near the floor
- Mold starting to show up in corners
- Cracks that look like they’re spreading
- Actual water on the floor after a heavy rain or fast snowmelt
If any of that sounds familiar, it’s worth having someone look before it turns into a bigger, more expensive job.
What We Actually Do About It
No two basements need the exact same fix, so we look at your specific situation first. Here’s what’s usually on the table.
Interior Waterproofing
We install a drainage system along the inside base of your basement walls. It catches water before it spreads across the floor and routes it to a sump pump, which pumps it out and away from the house.
Exterior Waterproofing
The more thorough option. We dig down to the foundation, apply a proper waterproof membrane, and replace the weeping tile where needed. Since it stops water before it ever touches the wall, it’s often the better call for the older homes we see around downtown Aurora.
Sump Pump Installation
A sump pump that actually works is one of the simplest ways to avoid a flooded basement. We install and service them, and we can add a battery backup too, so you’re still protected if a storm knocks the power out.
Foundation Crack Repair
Small cracks rarely stay small. We seal them properly, using methods meant to last, not a quick surface patch.
Window Well Fixes
A window well that doesn’t drain right is an easy entry point for water. We fix the drainage and add covers so rain and melting snow stop finding their way in.

Why Aurora Homeowners Choose J.M WaterProofing
There’s no shortage of waterproofing companies to pick from, so here’s the honest reason people go with us. We actually know this area, the moraine, the clay soil, the older downtown foundations that need a more careful approach. Our pricing is upfront, with no pressure to add things you don’t need. Our crew has handled everything from a single hairline crack to a fully flooded basement, so not much surprises us at this point. And when we leave, your property looks like we were never there, aside from the dry basement.
How long does the work take?
Interior jobs are usually done in a day or two. Exterior waterproofing takes a bit longer because of the digging, but we’ll give you a realistic timeline before we start.
Will it tear up my yard?
There’s some digging involved with exterior work, but we’re careful with landscaping and clean up thoroughly once we’re finished.
