A home in Stouffville, Ontario, had a crack in the basement wall. The crack was allowing water to leak into the basement and onto the floor. There was a tenant living in the basement and they were worried it would worsen and cause damage their belongings. The owner was worried about the leaking and didn't want there to be disruption to the home and their wallet. 

The customer called Clarke Basement Systems and spoke to Rob Malcomson, who explained the simple solution to the problem. Mark Dougherty and the team installed Flexispan on the crack. The Flexispan seals up cracks and moves with the wall to ensure any water entry is stopped.

A home in Stouffville, Ontario, had a history of leaking water in different areas of the basement. Our company had previously installed sump pump equipment and a smaller piece of our Waterguard system years ago, but the problem moved to a different part of the basement. The customer just wanted more installation of the Watergaurd because they knew it stopped the water issues the last time. There were renovated parts of the basement and the water was causing damage. Water was saturating the carpet and the baseboard and the house smelled very musty. The customer is in the medical field, and understood the urgency of keeping the basement dry. 

The customer called Clarke Basement Systems and talked to Ben Wallis who was the inspector and salesperson, he explained everything we would do from start to finish. Jose Martinez and the team came in and removed the wall materials, then opened up the concrete floor to install the waterproofing system. The WaterGuard was installed to prevents water from being able to reach the basement floor elevation. Thermaldry wall membrane was installed to prevent any future condensation, wall sweating or leakage behind the membrane. WaterGuard was installed around another significant area of the basement which was leaking. However, there is still more to come in the future. The customer only wanted the specific parts with water leakage and told us they would contact us again if the issues moved again, knowing we can add onto it over time. The customer was satisfied because they have solved the next phase in their leaky basement.

Basement Waterproofing & Crawl Space Waterproofing in Stouffville, ON

Basement waterproofing system in Stouffville, ON

The TrenchDrain surrounding this water heater will prevent any water from accumulating in this basement.

The city of Stouffville, ON experiences an average of 867 mm of precipitation every year, higher than many other cities in Ontario. Homeowners in Stouffville need a basement waterproofing contractor they can rely on when the weather causes problems for their homes. In business since 2003, Clarke Basement Systems is an established, experienced waterproofing company that knows the Stouffville area well. We will work quickly and effectively to solve your wet basement problems!

A large flood in your basement is not the only kind of water you should be concerned about, as even a small amount of water or moisture can lead to mould growth and other issues. Common signs of a basement water problem include:

  • Wet or damp basement floor or standing water
  • Leaking or damp basement walls or windows
  • Crystalline deposits on concrete surfaces
  • Musty odors, condensation, and humidity
  • Sump pump issues

Fortunately, Clarke Basement Systems has unique products to solve all of these problems, such as sump pumps, drainage systems, and dehumidifiers. We also take the time to think of the smaller details. Alternative means of removing water from your basement can be included in your waterproofing system, such as an escape channel if your drainage line freezes or a back-up battery in your sump pump so it won't stop working if the power goes out.

We also offer water heater protection and washer hose replacements that can stand up to high pressure. Finally, as crawl space waterproofing specialists, we carry a complete line of waterproofing products specifically designed for this space.

Clarke Basement Systems wants to give you peace of mind when you walk out the door that no matter what the day brings, your home will stay safe and dry. If this sounds like something your home is missing, schedule a free estimate for basement waterproofing today!

Foundation Repair & Concrete Lifting in Stouffville

Clarke Basement Systems also specializes in foundation repair and concrete lifting and leveling to provide structural support to your property. As a member of Foundation Supportworks, we have access to patented, warrantied products designed by geotechnical and structural engineers. All of our technicians have been fully trained and certified through the Foundation Supportworks network, ensuring a job well done.

Common signs of foundation problems include interior and exterior cracks in walls and floors, tilting chimneys, sticking windows and doors, and bowing walls. All of these problems can create dangers in your home. If a bowing wall is not addressed, it may collapse entirely; similarly, foundation settlement may result in the complete detachment of your home's chimney. While it would take a long time for these catastrophes to occur, the longer you wait, the more you will have to spend on foundation repair.

A stabilized foundation will improve the value of your home and give you peace of mind. Additionally, most of our services can improve the cosmetic aspects of foundation troubles – cracks may disappear entirely, and bowing walls can be completely straightened. When cracks in your driveway or sidewalk are caused by concrete slab settlement, the PolyLevel system we employ will also get rid of these cracks, mitigating tripping hazards and restoring beauty to your property.

No matter what problem your home is facing, it's always better to act sooner rather than later. Contact Clarke Basement Systems today to schedule a free estimate for basement waterproofing, foundation repair, or any of our other services! We serve customers in Stouffville and throughout Ontario.

Water Damage in Stouffville, ON

A customer in Stouffville, Ontario, contacted us about groundwater seeping into their basement. Water had been entering through the original foundation of their century home, damaging their valuables and causing a musty smell.

After meeting with Claude Mathieu, Senior System Design Specialist, our customer had a chance to look over a couple of system ideas. The systems were installed along the original century home basement. Dave, a foreman, and his crew installed:

 

  • 2 SuperSump® Premier Sump Pump Systems
  • UltraSump® Battery Back Up System
  • IceGuard® Discharge Line
  • WaterGuard® Drainage System
  • ThermalDry® Wall Membrane

 

The customer was so relieved that Dave and his team were able to waterproof the original foundation of their home so they could store their personal items in the space without worrying about water damage.

Solution to Old Home Leaking Problems, Stouffville, ON

A home in Stouffville, Ontario had a problem located in the low-ceiling basement in the northeast area of the basement. The home was old and leaked periodically in one place over the years. The homeowner was not comfortable selling his home without a dependable sump system to make sure the basement stays dry for the next homeowner. 

 

The customer called Clarke Basement Systems and talked to Ben Wallis, who explained everything that would be done to the basement. Mark Dougherty and the team first opened up the concrete floor and dug a hole to accommodate the sump pump. The SuperSump has a sealed lid, preventing moisture from evaporating into the house, and prevents bugs from feeding on an open water source. Then, the discharge line was run to the outside the house and an IceGuard flood protection device was installed on the exterior of the house as a fail-safe, ensuring the water will leave the house, even if the sump discharge drain pipe freezes solid. The customer was satisfied with this solution because he can now sell his home with a good conscience that he has done everything he can to prevent problems.

Waterproofing Lionel's Pony Farm & Petting Zoo, Stouffville, ON

A home in Stouffville, Ontario, was having water issues in the basement. This home was on the property of Lionel's Pony Farm & Petting Zoo. Water would leak into the basement through the old homes foundation and was making the basement damp and smelly. The homeowner had many responsibilities to attend to on the farm and needed to be sure this problem would be taken care of fast and efficiently. 

The customer called Clarke Basement Systems and spoke to Claude Mathieu who ensured the job would not be invasive and be done fast and correct. Claude explained what would be done to the basement and due to the big space, could take two days. Dave Jackson and the crew came in and installed a Waterguard drainage system round the perimeter of the basement. ThermalDry wall membrane was installed on all the walls to keep out any moisture and allow heat to stay in the basement. The team then installed a SuperSump and a TripleSafe  to ensure there would be no flooding. The job was done in one day and the customer was happy that their basement is now waterproofed and they no longer need to worry about it. It was done fast, correct and was not invasive at all!

Replacing Old, Troublesome Window Wells, Stouffville, ON

A home in Stouffville, Ontario, had water flooding into the basement during heavy rain, through the old windows of the basement. This was a result of the vertical drainage to the weeping tile system becoming clogged. The basement was finished and the water was damaging the finished walls and flooring. The area was becoming unusable and mold was starting to grow.

The customer called Clarke Basement Systems to fix the window wells around the home. They spoke to Ron Monk, who explained all the work that would be done. Brandon Clarke installed Sunhouse window enclosures in replace of the old galvanized window wells of the home. The vertical drainage was restored on the wells that had failed. The fitted cover keeps rain and debris out of well. The customer was satisfied because the well drainage was restored to prevent the wells from filling with water. The Sunhouses are more attractive than the galvanized wells and have a fitted cover to keep rain, leaves and debris out. The Sunhouses also reflected natural light into the basement.

They knew the sump pump needed to be replace and knew they wouldn't be able to sell in the future if the problem wasn't fixed correctly.

They called Clarke Basements Systems to waterproof their home properly so they didn't have to worry about future leaking and damage. They talked to Chris Luke who was the inspector and told them everything that they were going to do. Dave Jackson and the team came in and installed a SuperSump to upgrade from the old one. It collects any water from the newly installed WaterGaurd, with WaterGuard ports. It was installed around the perimeter of the room to collect any other leaking water.

Added Waterproofing System to Existing One, Stouffville, ON

A home in Stouffville, Ontario, had a history of leaking water in different areas of the basement.  The customer had finished parts of the basement and the water was causing damage. Water was seeping up between the floor and the foundation wall and it was a problem because water was saturating the carpet and the baseboard and the house smelled very musty. We had previously installed sump equipment and a smaller piece of our Waterguard system years ago, but now the problem in the basement has grown in other spots, so more of the Watergaurd was required to take this growing problem in-hand. The customer is in the medical field, and understood the urgency of keeping the basement dry. 

 They called Clarke Basement Systems and talked to Ben Wallis who was the inspector and salesperson and he explained everything we would do from start to finish. Jose Martinez and the team came in and removed the wall materials, then opened up the concrete floor to install Waterguard and ThermalDry wall membrane. The WaterGuard prevents water from being able to reach the basement floor elevation. Thermaldry wall membrane prevents any future condensation, wall sweating or leakage behind the membrane. WaterGuard was installed around another significant area of the basement which was leaking. However, there is still more to come in the future, but this is fine with the customer, as the way our system is designed, we can add onto it over time and the previously installed Waterguard and Thermaldry will not be compromised in the meantime. The customer was satisfied because they have solved the next phase in their leaky basement.

Crack in basement wall with some black mold
North Street in Stouffville
I purchased this house from my parents knowing there was probably a crack in the foundation. When I took down the drywall in the basement there it was, almost straight up and down the wall. I would like to get it looked at and get an estimate to how much it would take to fix, and how long it would take to fix it. (sooner the better).

Tenth Line in Stouffville
Hello, Our concrete stairs at the back of our house are sinking. This started last year and we noticed water entering the basement and pooling in the vapor barrier. My guess is the mounts that once supported the concrete stairs have pulled out of the foundation wall and now water is entering from those holes. We were wondering what it would cost to repair. Thank you

Clamerten Road in Stouffville
We have a corner in our unfinished basement where we see dampness on a visible crack (narrow crack visible from the bottom of insulation to the floor, about 1/2 mm thick), which has turned black. There is also a window close to the corner, and I am not sure if the moisture is entering from the window, or coming through the cracks from outside. Would it be possible to just have a visit so we can get an assessment of the problem, and the solutions possible? We are planning to have the windows changed anyways, so please advise if we should request a visit from Clarke only if the problem persists after changing the window and the caulking surrounding it.
