Basement Waterproofing Cost In Toronto
The cost depends on the type of waterproofing. The method of installation of the system is selected individually for each object. Therefore, what is the cost to have the basement waterproofed? You can find out only after the master inspects the premises.
The specialist will assess the damage to the foundation, the area where the object is located, the type of soil, the location of groundwater, the climate, and other factors that affect the humidity inside the basement. Also, the amount of necessary materials and additional work is necessarily considered in the basement waterproofing cost. The larger the area of the room and the more complex the landscape, the more expensive the system’s installation will be.
Before the provision of services starts, the master draws up an estimate, and if the price suits the client, he starts work. It is not recommended to save on waterproofing. The microclimate inside the basement and the life of the building depend on it.
Average Basement Waterproofing Interior Vs. Exterior Price In Toronto
The average cost to seal a basement is approximately $2,500 to $7,500 USD, or $4 to $10 per square foot, including labor and materials. Interior waterproofing is generally cheaper than exterior waterproofing, as it doesn’t require excavations or window well installations. Therefore, interior basement waterproofing costs range from $600 to $2,000 USD. For exterior waterproofing, including repair and drainage installation, the cost can rise to around $12,000 to $15,000 USD. The total cost depends on both the size and condition of the basement.

Waterproofing services consist of several stages:
- Evaluation of the object.
- Development of a system project.
- Budgeting.
- Preparatory work.
- Sealing the surface of the foundation and walls.
- Installation of the drainage pump.
- Disposal of wastewater from the facility.
- Treatment of the foundation with epoxy resin.
If the house has a damp basement, then, regardless of the cost to fix the water in the basement, it is necessary to make waterproofing. Getting inside the foundation through cracks, moisture gradually destroys it, reducing the structure’s life.
Interior Basement Waterproofing Cost
Unlike exterior waterproofing, the internal system is installed indoors. There are several methods for waterproofing a basement internally:
- A drainage system is installed under the floor covering.
- Channels for water drainage are mounted above the floor.
- The system is installed at the footer level.
The cost for a dry basement system includes epoxy, sealant, and waterproof membranes. The exact method depends on the basement’s layout and location. The average cost for waterproofing basement walls from the inside is around $85 USD per linear meter. Installing a drainage duct above the floor costs about $40 USD per foot, and installing the system at footer level costs between $27 and $47 USD per foot. Underfloor waterproofing typically costs between $33 and $73 USD per foot.
Exterior Basement Waterproofing Cost
There are several methods for exterior basement waterproofing, and the cost depends on the method chosen. This type of waterproofing is done outside the building, where a ditch is dug around the perimeter of the structure down to the foundation. The foundation is cleaned, cracks are sealed, and a waterproof membrane is applied. The cost of exterior basement waterproofing depends on the depth of the ditch and the condition of the foundation. On average, it ranges from $20,000 to $47,000 USD, with an approximate cost of $130 USD per foot. Due to the complexity of the work involved, exterior waterproofing is more expensive than interior waterproofing.
What Affects The Cost?
Basement sealing cost is affected by additional work:
- Eliminating cracks and microcracks on the surface of walls and foundations.
- Installation of window wells.
- Sealing windows and doors.
- Installation of downpipes and gutters.
- Installation of drainage.
- Cleaning of coatings from paint.
Also, the cost of waterproofing exterior basement walls is affected by the area of the room and its condition. It may be that additional work is required to strengthen the building.
Extra Repairs And Accessories
Selecting suitable waterproofing materials and system design is crucial. The climate in which the basement is located can also affect the work plan. In areas prone to frequent flooding, such as coastal regions, a drainage pump may be required, with costs ranging from $550 to $1,350 USD. Additional costs include the installation of polyethylene pipes, which range from $1.10 to $3.10 USD per foot, and French drainage systems, which cost between $12 and $28 USD per foot. If you’re waterproofing a crawlspace, additional costs may include wall leveling, window installations, flooring, and ventilation.
Basement Layout And Size
It is best to do waterproofing in a new room, planning the system’s location. If the basement is old, this increases the cost to fix the wet basement due to redevelopment and additional work to eliminate damage. When planning a basement, you need to consider not only the location of the drainage system, but also the purpose of its use. For food storage, the room is equipped with additional shelves. When creating a wine cellar – refrigerated wine cabinets. Accordingly, the area of the object directly depends on its purpose.
Our experts, who have extensive experience in their work, will help to develop a plan correctly. Considering all the nuances, they will help turn a wet basement into a dry and comfortable room you can use as a workshop.
Foundation Repair Or Reinforcement
After inspecting the object’s condition, our master will tell you the average cost of the waterproof basement and whether it is necessary to strengthen the foundation. In new buildings, most often due to shrinkage of the building, foundation repairs are required. For this, specialized cement mortars with water-repellent properties are used. If work is carried out in old buildings that have not been repaired for a long time, it may be necessary to strengthen the foundation. To do this, a moat is dug to the depth of the base of the building along its entire perimeter. A lattice is welded from the reinforcement, and it is poured with concrete after installation. Then a waterproof membrane is mounted, and the rest of the waterproofing work is done.
Labor Cost Basement Waterproofing
The cost to seal a basement depends on the extent of work and materials used. An evaluation by our specialists determines the final price. On average, waterproofing system installation costs range from $2,500 to $7,500 USD, with the lowest costs starting at $300 USD and the highest reaching up to $25,000 USD.
