Our customer in Etobicoke, Ontario, had an issue with the previously-built rear addition before they owned the home. Water had started seeping in through the walls and concrete floor which was damaging materials used to finish their basement and affecting personal items. They were concerned that mould might begin to grow behind the finished walls.  


After our customer spoke with Claude Mathieu, System Design Specialist, they agreed on a waterproofing solution plan. They started by removing the entire concrete floor to release the water pressure underneath. Jose, Lucio, Ali, and the crew installed:

SuperSump® Sump Pump System

WaterGuard® Drainage System

ThermalDry® Wall Membrane

IceGuard® Drainage Pipe

One Etobicoke, ON homeowner, was concerned with their unprotected current sump system. In the event of pump failure, power loss, or clogged and frozen discharge pipes their home would become flooded. This concerned the homeowner, as a result, could be a considerable amount of damages resulting in costly repairs and replacement.


Ron Monk, System Design Specialist, evaluated the condition of their home and provided a waterproofing solution. Ali Fereidouni, Foreman, and his team installed:

 UltraSump® Battery Back-Up system

Zoeller® M53 Primary Pump

CleanPump Stand

IceGuard® Discharge line

The IceGuard® Discharge Line protects the discharge line in the event of frozen or clogged pipes. If the pipes become clogged or frozen, some slots face away from the home that allows water to flow out freely.

Our customer in Etobicoke, Ontario, was not protected in the event of pump failure, power loss, or clogged and frozen discharge pipes. With no backup system, their home could become flooded and damaged resulting in costly repairs and replacement.


One of our System Design Specialists informed our customer on the products that Ali Fereidouni, Foreman, would be installing. Ali and his team introduced our patented:

UltraSump® Battery Back-Up system

Zoeller® M53 Primary Pump

CleanPump Stand

IceGuard® Discharge line

The UltraSump® System is designed to run 12,000 gallons of pumping, should the primary pump fail, or the home loses power.

Expert Foundation Repairs and Concrete Lifting in Etobicoke, ON

Here at Clarke Basement Systems, we believe in the value of customer service and are proud to serve your area. We use only high quality products, installed by our excellent team of certified technicians so that you can be sure of long-lasting results. We want to work with you to find the solution that will work best for you!

Problems with foundations often stem from broken soil or soil that has been weakened to the point where it can no longer support the weight of the structure. When this occurs, the best thing to do to remedy the problem is to install foundation piers and jack posts which will fix uneven, sloped floors. Additionally, wall anchors and I-Beam wall braces can correct walls that are leaning or bowing inwardly. 

Signs of Foundation Problems in Etobicoke, ON

  • 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 door
  • Tilting chimneys
  • Street creep

Reliable Basement Waterproofing and Sump Pumps in Etobicoke, ON

Problems with basements often stem from leaky pipes, sump pump failure, or flooding during heavy rain. If you find that your basement has a musty smell, pooling water, or mold and mildew, then you need to call in the experts at Clarke Basement Systems. We can repair water damaged walls and floor with matting and vapor barriers to seal out humidity and bugs while keeping the area energy-efficient. 

TripleSafe sump pump installed in Etobicoke, ON

To eliminate standing water in your basement or crawl space, the TripleSafe sump pump is the proven product that will get the job done. With a primary pump, secondary pump, as well as a third, battery operated backup pump, you can always have peace of mind knowing that your home is protected from water damage. In addition, our excellent drainage systems will deposit any water in your basement a safe distance away from the foundations of your house, keeping your home safe. 

Trusted Crawl Space and Mold Repairs in Etobicoke, ON

In many homes, the crawl space is the area of the home that is the most neglected. When a crawl space falls into disrepair, it can have detrimental effects on other areas of the home, such as the foundations. Don't let your crawl space become a health hazard and have it inspected by the professionals at Clarke Basement Systems. We can install vapor barriers, thermal insulation, and dehumidifiers to turn your musty, dirty crawl space into a clean, dry, energy-efficient area. 

Signs of a crawl space problem:

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

If you've found mold on in your crawl space, it is either surface mould or wood rot. With surface mould, it can be scraped off, but wood rot can destroy wood support completely. We have patented products like jack posts that will provide a solution for support beams that can no longer hold up weight. 

At Clarke Basement Systems, we are proud to serve our area and we put customer service as our top priority. Trust our team of knowledgeable staff and certified, trained technicians to provide a solution for all your basement, foundation, and crawl space repair needs. Call us today for a free estimate!

Job Stories From Etobicoke, ON
No Backup System in Etobicoke, ON

Our customer in Etobicoke, Ontario, had a problem with their existing sump pump system because it had no backup in case of pump failure or power loss. Also, the discharge line was not protected against freezing temperatures or getting clogged. Their house was at risk of flooding if they didn’t resolve the problem. If the basement flooded, their belongings and home could become damaged resulting in costly repairs and replacement.


Ron Monk, System Design Specialist, walked the customer through the process of waterproofing their basement. Ali Fereidouni, a Foreman, started the job using the existing sump pit and then he upgraded the primary pump. The team installed:

•    UltraSump® battery backup system

•    M53 Primary Pump

•    CleanPump® Stand

•    IceGuard® Discharge Line


The customer finally had peace of mind since their home is permanently waterproofed and protected for many years to come with our 25-year transferrable warranty!

Water damage in Etobicoke, ON

Our customer in Etobicoke, Ontario, had an issue with their basement. Water had been seeping in through the walls and up through the concrete floor. This was a problem because their finished basement and personal valuables were becoming damaged.


Claude Mathieu, System Design Specialist, spoke with our customer and advised them on a waterproofing solution. Lucio, Jose, Ali, and the crew installed:

  • a SuperSump® Sump Pump System
  • WaterGuard® Drainage System
  • ThermalDry® Wall Membrane
  • and a IceGuard® Drainage Pipe

The thermalDry® Wall Membrane system creates an efficient moisture and vapor barrier, helping to decrease basement humidity. It also stops water and any condensation from entering into your basement and directs it into your perimeter drainage system.


Our customer was happy with their new waterproofed basement. They can now use the space and store their personal items without the worry of water damage.

Solution to a Damaged, Moldy Basement, Etobicoke, ON

A home in Etobicoke, Ontario, had ground water leaking into the basement in a few areas. The flooring and baseboards were getting damaged and moldy. Water was damaging the finished basement, and personal items.

The customer called Clarke Basement Systems and spoke to our inspector, Claude Mathieu who explained the solution to the problem.  Dave Jackson and the team installed WaterGuard, ThermalDry Wall membrane and a TripleSafe sump system. The ThermalDry Wall membrane captures any ground water that may leak through the foundation walls, directing it to the WaterGuard. The WaterGuard also captures groundwater from footings, walls, floor joints, as well as from the under floor slab and takes the water to the TripleSafe sump pump to discharge outside through IceGuard. The IceGuard protects against frozen lines in the winter.

The customer is happy knowing that the basement is dry and healthy and the system comes with a Lifetime, transferable warranty.

I had water coming on the basement floor one side during the snow melting time few weeks ago.
Project Location: Etobicoke, ON
We live in a fairly old home (1960's) and the place was renovated 5 years ago, everything was done with exception of a small basement. While there has never been a flood in basement and the house is equipped with a sump pump and back stop valve, there is definitely moisture ingress from the cold room area which has cracked and exposed foundation/concrete areas. This has also resulted in an ingress of various types of pests over the past few years. We are planning to finish basement in the next year, and before looking at the options, am interested in having a professional inspection completed and any exposed or crack areas repaired, and walls completely insulated from inside to both resolve moisture and pest ingress. The basement area is less than 500 sqft. My availability is best over weekends in the mornings, am not sure if possible, but I would like to have someone come out and inspect Sunday morning (October 21, 2018). Please confirm. Thank you, Saloumeh
