    Mike E. of Toronto, ON, ON

    Customer Testimonial

              Extremely pleased with the job Clarke Basement Systems did to salvage our retaining wall. It was old and leaning more and more with every passing year. We knew we'd soon have to get it worked on or taken down and replaced. CBS gave us a fair estimate and did not over-promise as to results. They ended up righting it to within a few degrees of perfectly vertical. Lovely. They used a unique geo-engineered solution that involved putting steel plates on the exterior of the wall and linking by means of 3/4" steel rods to a set of steel anchor plates buried under the driveway. Don, Austin and Nolan were punctual, pleasant and did it right.

    Customer Testimonial

              it was a very good experience. Starting from the estimate - the estimator came in and was very professional. He gave me a good estimate and an approximate timeline. As it turned out your service departement called me before the timeline, so my work was done 2/3 weeks before I was anticipating. Your crew showed up on the scheduled time. They were pretty professional and diligent. The work was quite messy because they were doing lots of excavation and whatnot. But once they left the whole area was absolutely clean. There wasn't even a trace that there was any work was done here. They dusted the window wells and they showed me that the drainage system was ok by flooding it with water and everything. So, yea - I was quite impressed. Later there was a little bit of settlement in the gravel which they filled in. I gave you a call and the person showed up within a couple of hours and filled with gravel and everything. That was a few weeks later. I am quite satisfied with the work.

    Customer Testimonial

              “We have never written a review before, but felt compelled by this company and their product to do so. Our search for a contractor to repair our cracked and sinking foundation began three years ago. The parade of pick-up trucks with guys and their clip boards began. Of the contractors that did return our calls and show up, they gave us one different idea after the other on how to solve our foundation problem. None of them had a feasible solution. Year three, and one more search on the internet, we found Clarke Basement Systems. At first it seemed too good to be true; it looked like they had the system that would solve our problem. From the very first contact with this company we knew they where different from all the other contractors we had dealt with. Their sales rep, Chris, came to our home on time with a computer in hand and an answer to our problem. Foundation push piers were recommended to stop the sinking foundation, and they would attempt to raise our home to its original position. The owner, Don, with his crew showed up on time and worked on the job until it was completed. Four days later, the sinking corner of our home had been lifted back to level! The property showed virtually no signs of damage. They were professional every step of the way. We would highly recommend this company to anyone who has a similar problem, or for that matter, any issue with their foundation or basement.” - Mr. and Mrs. Byam

              Question: Why did you hire Clarke Basement Systems? Answer: They were the most informative company around for these types of services and the Salesman Rob was very friendly. He explained everything very thoroughly in terms that I can even understand because I don't have knowledge of these kind of things. the pricing was very fair ! Question: As of right now the waterproofing and crawlspace portion have been done, any comments on that? Answer: Both things were completed better than I expected. I am COMPLETELY satisfied with the work that was done.

    Customer Testimonial

              To those considering the use of Clarke Basement Systems. I'm writing this letter to recommend them as professional, customer-focused subject-matter experts. From pre-sales to clean up, they get the job done with an informative, "no dumb questions" approach to the customer experience, and above all, with the quality they'd expect if they'd been the homeowners. For us, they've fixed three window wells and two cracks in our home's foundation, and they've given us the confidence to shift from repairs to home improvements in the basement. Thanks again Don, and special thanks for being onsite and building quality into your business.

    Waterproofing a Basement to Renovate in Toronto, ON

    A home in Toronto, Ontario, had a problem in the basement. The homeowner wanted to finish the basement, but the walls and floor were always damp. The customer also wanted to install a heated floor and wanted to gain headroom. The homeowner didn't think they would be able to refinish the basement because it was always damp, and they wanted to ensure the protection of their investment. 

    The customer called Clarke Basement Systems, and Ron Monk explained the solution we had come up with for the home. Don Clarke and the team came in and installed WaterGuard® sub-floor perimeter drainage system, WaterGuard® port, ThermalDry® wall system, SuperSump® Premier Sump Pump System and UltraSump® Battery Back-Up system and IceGuard® Discharge Line System. 

    The Waterguard captures water at the footing wall joint and drains the water to the SuperSump/UltraSump sump system. The Thermaldry wall membrane helps reduce relative humidity and ensure wall leaks and any moisture are drained into the Waterguard installed in the floor.  The SuperSump and UltraSump is a 2 pump sump system. It protects against pump failure and power loss to the home. It is installed with the Iceguard that protects the system in cold weather. 

    The customer was happy because they were able to refinish the basement knowing the whole basement was going to stay dry. The homeowner was also very confident with Basement Systems 25-year dry nationally backed transferrable basement warranty against groundwater seepage.

    Melting Snow Causes Surface Water in Repair Shop in Toronto, ON

    A car repair shop in Toronto, Ontario has many cars coming in and out. In the winter the snow and slush melts and causes the garage floor to flood. The business owner and employees had to push the water to one small drain far away, taking time away from the customers. The business owner wanted a solution that would benefit the company and avoid loss of time.

    The owner called Clarke Basement Systems and spoke to Claude Mathieu, who explained the process to our solution. Don Clarke and the team came in and installed interior and exterior TrenchDrain® Drainage System and a SuperSump® Premier sump pump system. The TrenchDrain® captures the melting snow and water and drains it into the SuperSump. The TrenchDrain® was located in the floor at floor level in areas that the snow and slush would melt off the cars. The owner and employees no longer waste valuable time dealing with pooling surface water.

    Exterior Waterproofing in Toronto, ON

    A home in Toronto, Ontario had water entering through the foundation wall slowly. It was leaking in through the side and front walls making the space in the basement unhealthy and smelly. As most water leaking situations, the family was uncomfortbale and wanted to get it fixed before it got worse. 

    The homeowner called Clarke Basement Systems and talked to Rob Malcomson, who explained everything that was going to be done to the home. Don Clarke and his team came in and dug out the areas where the water was coming through. They did an entire exterior waterproofing. They installed Liquid rubber on the wall to cover any cracks and leaks, drainage matting on the walls to direct any water away from the home and back into the ground. New weepers were installed on the outside of the home to relieve any pressure against the wall. When they completed the waterproofing they filled in the hole and gave the customer the guarantee there would no longer be leakage. The Basement is now dry, with no water entry!

    Bigger Window and Dry Basement in Toronto, ON

    A home in Toronto, Ontario was experiencing basement flooding due to a window located close to a downspout. It was not draining away the water fast enough and when it rained the homeowners spent a lot of time mopping up the water to prevent damage from the flooding.

    The homeowner was pleased knowing they wouldn't have to waste any time cleaning up water that leaked into the basement. They wouldnt need to pay for damaged floors and the window brought in more light.

    Waterproofing a Future Business Space in Toronto, ON

    A home in Toronto, Ontario had water problems in the entire basement of the house. The house was 100-years-old with a stone foundation. They had groundwater seepage along the walls and hydrostatic pressure forcing water through areas of the thin and unlevelled, broken floor. The homeowner had to have mould remediation. Plans were made to finish the basement, so they wanted to ensure that it stayed dry and mold didn’t reoccur. The customers home office was in that room. He relied heavily on that room for his business, but due to the water, he couldn’t have his equipment in there.

    They called Clarke Basement Systems to fix the water problems so they could get their business workspace up and running. Our sales rep; Ron Monk explained to the customer that they would need floor removal and replacement, WaterGuard® Below-Floor Drain, TripleSafe™ Complete Sump Pump System, CleanSpace® Vapour Barrier, IceGuard® Discharge Line System. Dave Jackson, Jose Martinez and the team were prepared to take on this messy job and turn it into a clean, dry work space. The floor replaced provided a sub-floor drainage bed and an adequate three-inch level floor slab. WaterGuard® was installed around the full perimeter of the foundation to collect water and take it to a sump pump ensuring the whole basement stays dry. Cleanspace was put on the walls to reduce relative humidity, ensure wall leaks are drained to the WaterGuard® and protects the finished walls installed on top of it. The TripleSafe™ sump system ensures the basement stays dry all the time with the IceGuard® protecting the home in the event of frozen or blocked discharge lines.

    The client was satisfied because the basement is now dry and ready for finishing. They can now renovate that space and use it for their business without worrying about leakage or flooding!
