COVID-19 presented a plethora of unpredictable changes the world had never quite seen before. From children disallowed from going to school to institutions and businesses shutting down, the world pressed pause. Hopefully, with the worst of it now over, the global ramifications of the pandemic will echo on for years to come. One of the most significant changes for any office worker in any country on the planet was the switch to fully remote working environments. Because of this, we took everything previously done in person, like negotiations and meetings, to the online platform. Many people were now in need of precious office space in their own homes, and the biggest problem for most was that they didn’t have any. As peace and quiet became a thing of the past, the value of previously unfinished areas in a home instantly skyrocketed. Space became the hottest item for anyone looking to get some claustrophobic relief to get some work done.

One customer with an old home in Toronto desperately needed to renovate their basement to create some usable workable office space. They needed the freedom to be not only dry but also comfortable. The customer planned on renovating the space, spending thousands of dollars on materials and renovation contractors. The last thing the customer wanted was to do all that work and spend all that money in vain. They needed peace of mind they would be able to work comfortably and sustainably in their home basement. Their next call was to Clarke Basement Systems.

System Design Specialist Chris Luke used his depth of knowledge to develop a cost-effective and long-lasting solution for their specific basement needs. After consulting with the clients via their particular needs, Foreman Jose Martinez began his meticulous approach. Due to the nature of the customer’s specific basement seepage and considering their desire to remodel, a combination of systems were installed to ensure year-round, one hundred protection.

Firstly, Jose sealed the walls with our CleanSpace® sealant technology, keeping any moisture out. A small trench was dug up at the wall line, and the WaterGuard® drainage system was installed to drain any potential moisture. If any water does manage to penetrate the seal, the drains will flow to a SuperSump® Premier Sump Pump System along with an IceGuard® discharge system ensuring water safely and quietly pumps up and out to the main drain even in the coldest of weather. These systems are designed to last for years, with a 25 year fully transferable warranty. Meaning that they are some of the most successful basement waterproofing methods available today. Need more clean, dry space? Give us a call today.

A customer dealing with water seepage in her basement in Toronto, Ontario, needed some expertise on her next steps. She did not want to allow mold to grow and affect her family and her health.


Dave Jackson and an experienced crew installed our CleanSpace® wall membrane. The CleanSpace® wall system benefits basement walls for several days. Since it is a wall vapour barrier, it will direct all water seepage to the floor perimeter drainage system and keep the moisture out. It also provides basement walls with a bright, clean look that eliminates the need to paint.


Think the CleanSpace® system would be a good fit for your basement? Then, call us today and have your basement look like Samantha’s!

Dependable Foundation Repairs and Concrete Repairs in East York, ON

Issues with foundations are often caused by broken or weakened soil that can no longer support the weight of the structure. Some of the major signs of this are cracked floors or walls, tilting chimneys, street creep, or inward bowing walls. When this occurs, one of the ways to remedy the problem is to install foundation piers and helical piers which will correct uneven or sloping floors. GeoLock wall anchors are also good for fixing bowing, leaning walls, providing a permanent solution for foundation issues. 

Signs of a Foundation Problem:

  • Uneven or sloping floors
  • Cracks in the floor
  • Crack in interior wall
  • Inward bowing walls
  • Sagging floors over a crawl space
  • Hard to open windows and doors
  • Tilting chimneys
  • Street creep
  • Cracks in exterior wall

Tired of tripping over uneven concrete on your sidewalks or patio? Then you need our PolyLevel® concrete lifting, NexusPro cracked concrete repair, and SealantPro concrete sealing system. Our solutions are designed to be faster, easier, and more cost-effective than traditional methods of repairing concrete slabs, such as slabjacking or mudjacking. 

A failing garage lintel can also be a sign of structural settlement. Cracks along the brickwork, sagging, and pulling away from the home are all signs of a failing garage lintel. We offer expert garage lintel repair by installing the patented LintelLift garage lintel repair system.

Reliable Crawl Space and Mold Repairs in East York, ON

Crawl space with vapor barrier installed in East York, ON

As an area of the home that can often be neglected, crawl spaces can easily fall into disrepair, causing more serious problems for other areas like the foundations. If you've noticed sagging floors above your crawl space, musty odors, or even mold growth, then it's time to get your home inspected by a specialist. Our technicians can install vapor barriers, thermal insulation, and dehumidifiers to turn your water damaged, unsafe crawl space into a healthy, clean area. 

Mold damage and wood rot can be very destructive to crawl space support beams and can be very costly to replace. By having your home inspected by the professionals at Clarke Basement Systems, we can install products like jack posts to reinforce sagging beams while eliminating the source of the problem using insulation. 

Clarke Basement Systems has the tools and the expertise to get your job done right the first time. Our team of friendly, knowledgeable staff and certified technicians want to work to find a solution that will best fit your home and your budget! Call us today for a free estimate!

Job Stories From East York, ON
Waterproofing in Toronto Home

This customer from Toronto, Ontario, needed help when she discovered a significant amount of water seepage coming down her basement walls. There was also a strong odour that accompanied the moisture and water seepage. They called Clare Basement Systems with hopes of finding a permanent solution to protect her basement before things got worse and mold started to grow.


The solution was to go with a standard drainage system that uses our WaterGuard® product that will guide any water to the SuperSump® pump. They also encapsulated the home with our patented CleanSpace® water vapour wall membrane. Together the three products will work together to keep the space clean and dry.

Hello, We live in a semi-detached house and our and our neighbour's kitchens share the same crawl space. We discovered there is a small opening/broken board to the shared crawl space which raccoons have been using to enter the crawl space (under our decks). We are looking to close off the opening and ensure the crawl space has no issues, so we no longer have raccoons living under our kitchen. What do you recommend to do and what would the estimated cost be?
Project Location: East York, ON
Hello, I am the owner of the home and the landlord. The tenants called and said the crawl space is damp and moldy after the rain we had on Sunday. We need to find out why. We did notice that the neighbour has had their sidewalk done between our two homes and it definitely sends all the water to our side. Need to speak with you as soon as possible. Thanks, Renee Bovos
