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.
