A customer in Stouffville, Ontario, contacted us regarding water leaking through the original foundation of their home. During heavy rain falls, the basement area would become flooded. Dave, a Foreman, and his crew installed a WaterGuard® Below-Floor Drainage System that was placed along the perimeter of the basement and collected water draining from the ThermalDry® Wall Membrane. The water is directed to the SuperSump® Premier Sump Pump System. These systems work together to prevent water from entering the house and redirects the water back outside.

A customer in Stouffville, Ontario, had an issue about the original foundation of their century home. The original foundation had been letting in a lot of water which was damaging their belongings. During heavy rainfalls, the area would flood creating a musty smell. A ThermalDry® Wall Membrane was placed on top of the original foundation to collect moisture and water. It drained the water into the WaterGuard® Drainage System. Our customers were thrilled to have kept the original foundation of their home intact which made their basement dry and useful again.

  • Wet or damp basement floor
  • Leaking or damp basement walls

  • Musty odors
  • Condensation
  • Leaky basement windows

If you want absolute peace of mind when it comes to your basement, then you need the TripleSafe sump pump.

Expert Foundation Repairs and Concrete repair in Richmond Hill, ON

Many of the foundation problems that homes face look larger and more complex than they might actually be. The main reason for most foundation problems is shifting, weakened soil that can no longer support the weight of the structure. Some of the major signs of foundation problem in you home are:

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

If you have cracked, uneven concrete on your floors, sidewalks, or patios, then you need the professionals at Clarke Basement Systems to install our PolyLevel® Concrete lifting, NexusPro cracked concrete repair, and SealantPro concrete sealing solutions.

The PolyLevel® solution is injected under the concrete to raise it to the right height, making it a faster, easier, and more cost-effective solution, not to mention it lasts longer than traditional methods. NexusPro is applied to effectively seal concrete cracks and joints. This cracked concrete repair solution is ultra-durable and won't deteriorate in extreme temperatures, fluctuating weather patterns, exposure to UV rays, and more. Our SealantPro concrete sealing solution guards against oil, gasoline, liquids, and debris to effectively extend the life of your slabs by 3 to 5 times overall in just one quick application. SealantPro is versatile and can secure your concrete regardless if it was just repaired or newly installed.

Garage lintels can also fail over time because of all the weight it holds up above your garage door. 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.

Crawl Space and Mold Repairs in Richmond Hill, ON

As a part of the house that can often be neglected, a crawl space can become a breeding ground for mold, mildew, and even small animals or other pests if left unchecked. When this happens, trust the experts at Clarke Basement Systems to install vapor barriers, thermal insulation and dehumidifiers to turn your dirty, musty crawl space into a healthy, energy-efficient space. 

Major signs of a crawl space problem:

  • Sagging floors
  • Condensation
  • Mold
  • Wood rot
  • Foundation problems

Mold can be a silent killer in your home which is why you should have your home inspected regularly. Wood rot can also be a huge problem because when left unchecked, it can eat through wood, making it incapable of holding up the floor above the crawl space. We can install crawl space jack posts to correct sagging beams and keep your home a safer place. 

Clarke Basement Systems is committed to customer service because we are proud to serve our area. Let our team of knowledgeable staff and skilled technicians find a solution that will work for both your home and your budget. Call us today for a free estimate!

Job Stories From Richmond Hill, ON
Moving Forward with Renovations in Richmond Hill, Ontario

In Richmond Hill, Ontario, a newly owned home needed some TLC before the family's wishes to renovate could come true. with a wet basement perimeter, and a moldy stench, they contacted Clarke Basement Systems, and our team knew exactly what this basement needed! 

First, to prevent any more water from damaging the basement installation foreman Dave Jackson and his trustworthy crew installed a WaterGuard system to give the water a place to go once it enters the basement. Secondly, they put what is known as our CleanSpace wall vapor barrier system in place. the membrane will eliminate any further moisture from being trapped in the interior of the basement. 


After the job was completed, this family happily started their renovations with the confidence that they wouldn't have any future water problems!

Heaving Foundation in Garage, Richmond Hill, ON

A home in Richmond Hill, Ontario, had a heaving foundation in the Garage because of frost and was sinking due to improper soils. This was damaging the home's foundation and causing cracks in bricks. The homeowner was worried the Foundation wouldn't hold the house from falling down.

The customer called Clarke Basement Systems. Claude Mathieu explained the solution for the home. Don Clarke and the team installed Push Piers, drainage membranes, insulation and filter stone. The piers stop the sinking and the drainage membranes and insulation is to protect against frost damage. Proper drainage of ground water directed away from the homes foundation and the insulation makes it hard for frost damage.

The customer was satisfied that they no longer have to worry about damage to the foundation.

Water problems in diagonally opposite corners of a finished basement. Corners with leaks are either not finished or semi-finished. After reading about potential solutions on your web site, I thought maybe the in floor perimeter drain and sump pump option might be the right solution for my home. I would like to discuss options with you as soon as possible.

We are buying a century home that has a weeping system discharging into a 2X2X3ft concrete well in the basement and the water is drained out of it using gravity discharging directly into the sewer. The system has been operational for over 70 years and it works well, however, there are some areas of the basement that show some moisture. We would like to get your opinion about the current system and whether it would be recommendable to install a sealed sump pump system like the ones you offer and connecting it to the existing weeping system. Also would like to have an idea of the price range for such a system including installation. Thanks
