Example of Exterior Basement Waterproofing Project in Toronto, near CN Tower

Exterior basement waterproofing is considered the most durable solution. It involves excavating around the foundation and repairing wall cracks. Basement walls are then sealed with waterproofing membranes and other waterproofing materials.

Exterior Waterproofing Cost - $100-$300/linear foot

Basement Underpinning Project in Progress near Nathan Phillips Square in Toronto

Basement underpinning is a construction technique used to increase the depth or strengthen the foundation of an existing building, particularly in cases where the current foundation is inadequate or needs improvement. It involves excavating and extending the depth of the foundation below its original level and then reinforcing it to provide additional stability and support. This process can be employed to create more headroom in a basement, increase the load-bearing capacity of the foundation, or address issues related to foundation settling or structural concerns. Underpinning is typically carried out by professional contractors and requires careful engineering and planning to ensure the safety and structural integrity of the building.

Basement Underpinning Cost - $85-$450 per linear foot

Waterproofing Contractor Installing a Window Well

Window wells are structures designed to allow natural light and ventilation into basement or below-grade spaces, typically found in homes with partially or fully underground lower levels. They are essentially excavated spaces outside basement windows that are surrounded by walls or barriers to prevent soil from collapsing into the window area. Window wells are connected to the weeping tile (drainage system) to prevent water from pooling. 

Window Well Installation Cost - $1,600-$4,000

Plumbing Rough Ins Installed in the Basement

Basement plumbing rough-ins & basement bathroom rough-ins are some of the most popular services along with new construction waterproofing. They involve our team of Aquamaster waterproofing contractors installing pipes and vents for the plumbing system in new construction projects. This service involves routing pipes through wall cavities, running vent stacks to the roof, laying underground pipes, and installing fixtures and end elements etc.

Example of Interior Basement Waterproofing Project

Internal waterproofing is another approach to waterproofing. It involves managing the water that already made it to your basement, as opposed to preventing the leaks (the way interior waterproofing does). Waterproofing membranes will be installed inside the basement and will direct water to the drainage systems and the sump pump will push the water outside your basement. this solution is more cost-effective upfront but will require more maintenance long term. Interior waterproofing is considered less effective compared to exterior solution.

Interior Waterproofing Cost - $70-$350/linear foot

Basement Wall Crack Repair in Progress

Cracked basement walls or floors will almost 100% lead to water leaks or even worse. After the basement cracks are detected, we will go for foundation crack repair. Foundation cracks will be injected with an epoxy-resin solution that bonds the pieces of the concrete foundation together. While larger basement wall and floor cracks may require other repairs.

Foundation Crack Repair Cost - $1,500-$3,200


Basement leak detection services are the first step our team will take before the leak repair. Pipes, basement wall cracks, and many other issues can create wet or damp basement walls & floors. Our team has all the necessary equipment and training to identify the source of the leak and repair it.

Waterproofing Contractors installing a weeping tile in front of CN Tower

Weeping tiles, also known as foundation drains or perimeter drains, are a drainage system installed around the perimeter of a building's foundation to manage groundwater and prevent water from accumulating around the foundation. Despite the name, they are not actual tiles but rather a system of perforated pipes or tubes used to channel excess water away from the foundation.

Sump Pump Installation and Battery Backup Replacement Example

A sump pump is a mechanical device used to remove excess water that accumulates in a low-lying area, typically a basement or a crawl space, to prevent flooding and water damage. It consists of a pump placed in a pit or "sump" that collects water that has entered the space. When the water level in the sump pit reaches a certain point, the pump is activated, and it pumps the water out through a pipe that leads away from the building to a location where the water can safely drain.

Sump pumps are particularly useful in areas prone to heavy rainfall, flooding, or where the water table is high. In some cases, your basement may have multiple sump pumps installed, depending on the amount of water that needs to be managed.

Sump Pump Installation Cost - $500-$3,600

Installation of Backwater Valve or a Backflow Preventer

Backwater valve is designed to prevent sewage or wastewater from flowing back into a building's drainage system. It's installed in sewer lines to protect properties from potential flooding caused by sewer backups during heavy rain or other instances of overwhelmed municipal sewage systems. The valve allows wastewater to flow out of the building but closes when water tries to flow back into the building, thus preventing contamination and potential damage. Backwater valves are an essential component of flood prevention systems, particularly in areas prone to sewer backups.

A waterproofer sealing the crawlspace of a building

Crawlspace encapsulation is a process of sealing and insulating the crawl space beneath a home to create a controlled environment that helps prevent moisture-related issues and improve energy efficiency. Our experts can help identify the best solution to crawlspace sealing and any additional services you may need with it - dehumidifier installation, sump pump installation and more.

Example of Basement Walkout

Basement walkout construction involves creating a direct entry or exit from a basement to the outside, typically at ground level or slightly below. This construction allows easier access to the basement area and can serve various purposes, such as adding extra living space, creating a rental unit, or providing convenient access for storage. This service is often combined with the basement wall and window cutouts to modify your basement further & increase its usability.

How Much is Basement Waterproofing in Orillia?


An average basement waterproofing project in Orillia costs from $70-$350 per linear foot with an average price of basement waterproofing of $100 per linear foot. The specific price will depend on the waterproofing method, depth of the foundation, extent of the foundation damage, and scope of the project and waterproofing materials used.

Wondering Why Does your Basement Leak?

Common Causes of Basement Water Leaks in Orillia

Basement water leaks can be a frustrating and damaging issue for homeowners. There are several common causes of basement water leaks, each of which may require different approaches to prevention and repair. Here are some of the typical culprits:


  • Poor Drainage - improperly graded soil around the foundation can lead to water pooling against the basement walls. This can increase hydrostatic pressure and result in water seeping through cracks or porous areas.

  • Foundation Cracks - over time, the foundation can develop cracks due to settling, shifts in the soil, or other factors. These cracks can allow water to infiltrate the basement. Cracks can vary in size and depth and may require different extent of basement crack repairs. If you have wall cracks you may see basement wall & floor water leaks which are important to repair sooner rather than later to prevent them from getting worse.

  • Clogged or Malfunctioning Gutters and Downspouts - if your gutters and downspouts are clogged or not functioning properly, rainwater may overflow and collect near the foundation, contributing to basement leaks. There is a number of other wet basement problems that a leaky gutter can cause.

  • Sump Pump Issues - a malfunctioning sump pump or the lack of a sump pump altogether can result in water accumulation in the basement during heavy rainfall or flooding.

  • Poor Sealing - inadequate sealing of basement walls or floors can lead to water infiltration. Waterproofing materials may deteriorate over time, allowing water to penetrate.

  • Hydrostatic Pressure - this occurs when the water table rises due to heavy rainfall or other factors. The increased pressure can force water through cracks or the porous surface of the foundation.

  • Lateral Pressure - if the soil around the foundation becomes saturated with water, it can exert pressure on the basement walls, causing them to crack or bow.

  • Window Wells and Leaky Windows - improperly sealed or poorly designed window wells can allow water to collect and seep into the basement. Leaky basement windows can also contribute to water infiltration.

  • Plumbing Leaks - leaking pipes or drains within the basement can introduce water into the space.

  • Condensation - in humid conditions, condensation can form on cool surfaces in the basement, leading to dampness and potential mold growth.

  • Exterior Factors - poor landscaping practices, such as planting bushes or trees too close to the foundation, can lead to increased moisture retention around the basement walls. In some cases leaks may also occur because the weeping tiles don’t work properly, are clogged or not installed properly.

  • Natural Disasters - flooding caused by heavy rain, storms, or snowmelt can overwhelm drainage systems and lead to basement leaks. A lot of water can cause a variety of basement waterproofing issues.

Basement Waterproofing Reviews

What Our Clients Say?


Stephanie G.

Residential Client

I used Aquamaster for two separate home waterproofing projects and I was extremely satasified with their work and price. Their team are highly skilled, thorough and were able to complete the 10.5 hour job in one day. They were even kind enough to seal my window frame after I noticed a minor leak. I would highly recommend Aquamaster for all your waterproofing and plumbing needs.

The Aquamaster team is absolutely fantastic! They went above and beyond to diagnose and correct the problem that I had with my basement plumbing caused by old pipes and persistent tree roots. I used them once in 2012 and in 2020. I cannot say enough good things about this team - Highly recommend.
