Basement Crack Repair
CrackStop provides both interior and exterior basement crack repair. We recommend the method that best fits your home, your basement, and the actual problem.
Two Methods. One Decision.
We Offer Both Interior and Exterior Repair
The right method depends on the crack, the home, access conditions, and your priorities. We assess your situation honestly and recommend what makes the most sense — not what's easiest or most expensive for us.
Interior Crack Injection
Crack injection seals the wall from inside using epoxy or polyurethane resin — no excavation, no yard disruption. The crack is cleaned, injected through the full wall depth, and permanently sealed.
- No excavation required
- Completed in hours
- Significantly less expensive in most cases
- Works well when exterior access is limited
- Year-round — not weather dependent
Exterior Crack Repair
Exterior repair involves excavating alongside the foundation wall to access the crack from outside, applying waterproofing membrane directly to the wall surface. The right choice in specific situations.
- No interior disruption to drywall or finishing
- Addresses crack and waterproofing membrane together
- Better when exterior access is unobstructed
- May suit heavily finished basements
- Allows inspection of the exterior wall face
In some cases, the drainage or waterproofing work involved may fall within RainWise program criteria — depending on how the project is structured and approved before work begins. Learn more about RainWise-aligned projects.
How We Decide Which Method to Recommend
Basement finish level
Heavily finished basements can make exterior repair less disruptive.
Exterior access
Decks, patios, or tight clearances can rule out excavation.
Crack type & condition
Some crack types are better suited to a specific method.
Water involvement
Active or recurring leaks may influence which method seals more reliably.
Budget
Interior injection is typically significantly less expensive.
Homeowner priorities
Minimal disruption? Maximum exterior protection? That shapes the call.

"Had four quotes and Crack Stop was by far the best deal considering the materials, warranty and the knowledge of my foundation. The work was started in less than week and took one day to complete. You'd be crazy to go with anyone else in my opinion."
