Why foundation crack repair matters
keep water out, keep your home strong
Even small cracks can allow water to enter your basement, leading to moisture problems, mold, and structural damage over time. Professional crack repair protects your home, improves indoor air quality, and helps maintain your property’s value.
Common Types of Foundation Cracks
Different Cracks Different Solutions
We assess and repair all foundation crack types in Ontario homes.
Vertical Crack
Common and often caused by settlement. Can allow water entry, and should be professionally sealed.
Horizontal Crack
Often the result of hydrostatic pressure, resulting in reduced structural integrity of the wall.
Stair-Step Crack
Typically found in concrete block foundations due to soil movement or frost action.
Corner Crack
Occurs where walls meet, often due to settlement or shrinkage. Can be sealed to prevent water intrusion.
OUR CRACK REPAIR PROCESS
Every foundation crack is different. We assess the foundation, crack condition, and source of water intrusion before selecting the appropriate preparation method and repair material.
Inspection
We assess the crack type, foundation material, moisture conditions, and potential cause to determine the appropriate repair method.
Preparation
The crack is prepared according to the foundation type, crack condition, and repair method to ensure proper bonding and penetration.
Repair
Depending on the crack and whether it is dry, damp, or actively leaking, the appropriate industrial-grade epoxy/polyurethane is selected and injected at the required viscosity.
Final Inspection
The completed repair is inspected to verify proper sealing and ensure the crack has been treated according to the required repair method.

SIGNS YOUR FOUNDATION CRACK NEEDS ATTENTION
NOT ALL FOUNDATION CRACKS IN ONTARIO ARE THE SAME
Foundation cracks can develop for different reasons and don’t always require the same repair. Crack direction, width, movement, moisture conditions, and foundation type can help determine whether a crack is primarily a water-entry point or a sign of a larger foundation concern.
ACTIVELY LEAKING CRACKS
Water entering through a crack indicates a direct pathway through the foundation and should be properly assessed and sealed.
WIDENING OR MOVING CRACKS
Cracks that increase in width or show displacement may indicate ongoing foundation movement and require further evaluation.
HORIZONTAL CRACKS
Horizontal cracking can be associated with lateral soil pressure and should be evaluated for potential structural concerns.
STAIR-STEP CRACKS
Stair-step cracking in block or masonry foundations can indicate settlement or movement within the foundation.
WHITE DEPOSITS OR STAINING
Efflorescence, discoloration, or staining around a crack can indicate that moisture has been travelling through the foundation.
PREVIOUSLY REPAIRED CRACKS
A crack that has reopened or begun leaking after an earlier repair may require a different repair method or further investigation.

Common Questions
Questions from Ontario Homeowners
How much does basement waterproofing cost?
Basement waterproofing costs vary based on the repair method, project size, accessibility, foundation conditions, drainage requirements, and restoration work. Interior and exterior systems can differ significantly in price.
Should I waterproof my basement from the inside or outside?
The right approach depends on where the water is coming from, foundation conditions, accessibility, drainage, and the objectives of the repair. Exterior systems address water outside the foundation, while interior systems collect and redirect water that reaches the basement perimeter.
Are foundation cracks serious?
Not every foundation crack indicates a serious structural problem. Crack direction, width, movement, foundation material, moisture, and surrounding conditions should all be considered when determining whether repair, monitoring, or further evaluation is appropriate.
How long should a sump pump last?
A residential sump pump commonly lasts around 7–10 years, although operating frequency, pump quality, installation, maintenance, and groundwater conditions can significantly affect its lifespan.
Why does my window well keep filling with water?
Window wells can fill because of poor grading, heavy rainfall, clogged or missing drains, insufficient drainage stone, improper well height, or problems with the drainage connection.
Can poor grading cause basement leaks?
Yes. Ground that slopes toward the house can direct rainfall and snowmelt toward the foundation. Improving grading can reduce surface water around the home, although other foundation or drainage problems may still need to be addressed.
