We hear this all the time from new clients:
“Company X says they can waterproof my basement from the inside for half the cost. Isn’t that just as good?”
Here’s our honest answer: no, it’s not. Not even close.
At Basement Remedy, we do things the right way—the way that actually works long-term. And that means understanding the difference between interior basement waterproofing and exterior waterproofing.
Let’s walk through both options and why one is often a temporary patch, while the other is a real solution.
What Is Interior Waterproofing (Really)?
Interior “waterproofing” is a term many competitors use, but in most cases, they aren’t stopping water from coming into your home. They’re just hiding it or redirecting it.
Here’s what interior waterproofing usually includes:
- Installing vapor barriers along basement walls
- Digging small trenches inside to route water into a sump pump
- Laying perforated pipe beneath the basement floor
- Replacing drywall or paneling over problem areas
This might help manage water after it gets in, but it doesn’t stop the cause. You’re still letting water reach your foundation—and sometimes your basement floor—before it gets redirected.
That’s not waterproofing. That’s water management.
What Real Exterior Waterproofing Looks Like
True waterproofing means water never enters your home to begin with. Here’s what that looks like when we do it right:
- Excavating down to the base of your foundation
- Cleaning and sealing the exterior wall with waterproof membranes
- Installing proper footing drains (or replacing failed ones)
- Backfilling with gravel and soil that promote drainage
- Redirecting runoff away from the home via new downspout lines
It’s a more labor-intensive process—but it stops the water instead of just managing it. And that makes all the difference in keeping your basement dry for good.
The Risk with Interior-Only “Fixes”
Interior waterproofing might seem like a cheaper solution, but here’s what you’re risking:
- Ongoing moisture problems that come back every season
- Mold growth behind vapor barriers or finished walls
- Degrading foundation walls from constant water pressure
- Ruined investments in finished basements or home gyms
We’ve had customers come to us after spending thousands on a vapor barrier system that failed within a year. Why? Because the actual leak—on the outside—was never fixed.
When Interior Solutions Make Sense
To be fair, there are some situations where interior drainage has a role:
- If excavation isn’t an option due to property layout or budget
- In unfinished basements where water is minimal
- As a supplement to exterior work
But in those cases, we’re always upfront: it’s a compromise. It may help short-term, but it’s not a permanent solution to a leaking foundation.
Trust the Ground-Up Fix
At Basement Remedy, we specialize in full exterior excavation and waterproofing systems. We’ve seen firsthand how well it works—even in homes with extreme flooding issues. One client had water coming in from field tiles 24/7—we sealed the foundation, rerouted the drainage, and turned their indoor swamp back into usable space.
It wasn’t cheap or fast. But it worked. And it’s still working.
So, Which Do You Need?
If you’re seeing signs of moisture, don’t settle for a half-solution. Let us inspect your property and give you the truth. We’ll show you:
- What’s causing your water problem
- Where it’s coming in
- What your options are—both short-term and long-term
And yes, the inspection is free.
