Marc D. Marc D. Markham, ON

I had ongoing water infiltration issues in my basement and no sump pump to handle it. After finding Basement Systems Toronto online, I reached out and was impressed by their quick response and professionalism. A specialist came to my home for a free inspection and recommended the waterguard system and a sump pump. The installation team, led by Colin, did an amazing job. They installed everything efficiently, cleaned up afterward, and left my basement looking great. I’m now comforted knowing my basement is protected. Highly recommend their services!

After our basement flooded twice, we knew we needed help. Basement Systems Toronto set us up with a new Triplesafe sump pump, and the whole process was super smooth.

Fred V. Fred V. Vaughan, ON

I had concerns about the damp, uninsulated crawl space in my older Vaughan home. The team at Basement Systems Toronto was professional from the start—scheduling a detailed inspection and walking me through everything. They installed the CleanSpace encapsulation system, SilverGlo insulation panels, SmartJack supports, and a SmartSump with IceGuard for drainage. The difference is incredible—my home feels safer, more energy-efficient, and I have peace of mind knowing the structure is properly supported. Highly recommend their thorough and reliable service!

I couldn’t be happier with the work Basement Systems Toronto did in my crawl space! I was dealing with water infiltration and worried about the stability of the floor above. After finding them online, I quickly received a response and scheduled a visit from their specialist. He explained everything clearly and recommended the Smartjack system and a sump pump. Colin and the installation team were professional and efficient, and the results are incredible. My crawl space is dry, and the floors feel solid again. I’m so relieved and highly recommend them!

Eric E. Eric E. MCCOWAN RD

Basement Systems Toronto did an incredible job fixing my crawl space in Cedar Valley. I had sagging floors and persistent humidity issues that were causing mold, all because the main beam was poorly supported. They quickly assessed the situation and installed a CleanSpace liner, SmartJacks for support, and a SaniDry Sedona dehumidifier. The difference is night and day—my floors are level, the air is fresher, and I know my crawl space is protected for the long term. Highly recommend their services!

Lina & Mac M. Lina & Mac M. GLADSTONE AVE

Colin did a good job. He clearly explained what he would be able to do, given our existing sump pump system and its spatial limitations. He modified our contract to adapt it to the new parameters. He completed the job and showed us what he was doing at each step. We recommend this excellent worker without hesitation.

Job Stories From Unionville, ON

Basement waterproofing in Unionville, Ontario

In Unionville, ON, a homeowner faced significant challenges due to water infiltration in their basement, particularly after the heavy rainfall seen in recent years. Despite already having an exterior French drain installed, water continued to accumulate. The problem was exacerbated by a sloping parking lot that directed water toward their garage door and through house cracks, leading to damage on their epoxy-finished floor and drywall.

To address this complex issue, our team at Basement Systems Toronto provided a comprehensive and trustworthy solution. Our advanced WaterGuard® interior perimeter drainage system was installed just below the basement floor surface. This innovative system efficiently directs water seepage from the foundation walls and surrounding areas towards our high-performance TripleSafe™ sump pump. The TripleSafe™ system is crafted for reliability, featuring three pumps to accommodate high water volumes and maintain operation during power outages via its UltraSump™ battery backup.

To ensure a complete and safe discharge of water outside the home, we added a LawnScape outlet. This system directs water away from the foundation to a landscaped area, preventing pooling near the house and reducing the risk of future infiltration. To further safeguard against the potential of frozen pipes, our IceGuard® system was included to ensure an unblocked discharge route in winter conditions.

The execution of this targeted solution not only reaffirmed our commitment to providing a remarkable customer experience but also delivered a dependable and enduring result for the homeowner. Upon completion, their basement was secured against future water infiltration, restoring its usability and protecting it for years to come. Our approach bolstered their confidence, knowing their home now had a robust, systems-backed defense against the persistent challenge of water entry.
