How Much Does Exterior Basement Waterproofing Cost in Toronto?

Exterior Basement Waterproofing in Toronto costs from$100-$300 per linear foot depending on the scope of the project and other details.
How Exterior Basement Waterproofing Works? Exterior Waterproofing System is installed outside the basement walls and helps minimize the interaction that your foundation walls have with groundwater.

Process of Exterior Basement Waterproofing:

  • Exterior Basement Waterproofing involves the excavation of the soil surrounding the foundation to expose the walls
  • Walls are then cleaner and foundation cracks are repaired
  • Multiple layers of basement waterproofing membrane are applied to the walls
  • Drainage system is installed to help reduce the amount of groundwater accumulated around the foundation
  • The trench is then backfilled following a special methodology
  • Landscaping work is done

Benefits of Exterior Basement Waterproofing

  • Helps minimize contact between groundwater and the foundation walls, this helps protect the foundation from structural damage.
  • Actually prevents water from entering the basement
  • Doesn’t require maintenance, unlike internal basement waterproofing

Downsides of Exterior Basement Waterproofing

  • Exterior Basement Waterproofing projects often cost more compared to interior waterproofing
  • External waterproofing takes longer to complete
  • Is more disruptive as it involves excavation around the foundation
Interior Basement Waterproofing

How Much Does Interior Basement Waterproofing Cost in Toronto?

Interior Basement Waterproofing in Toronto costs from $70 to $350 per linear foot depending on the specifics of the project. The cost of an Interior Basement Waterproofing Project ranges between $15,000 and $30,000 depending on the size of the basement, extent of the damage and other factors described below.
  • Process of Interior Waterproofing – In most basement waterproofing projects interior basement walls are cleaned, and wall cracks are repaired. A waterproofing membrane is installed on the walls. The waterproofing membrane directs the water to the drainage system, once the water in the drainage system reaches a certain level a sump pump pumps the water out of the basement.
  • Benefits of Internal Waterproofing – is less expensive up front, can be completed faster, is less disruptive (doesn’t involve excavation around the building).
  • Downsides of Internal Waterproofing
  1. Internal waterproofing requires maintenance of the sump pump and has costs associated with it
  2. A broken sump pump can lead to basement floods
  3. Internal waterproofing does protect the foundation from structural damage as the groundwater interacts with the foundation
Factors that Impact Basement Waterproofing Cost in Toronto

Factors we Look at When Estimating the Cost of Basement Waterproofing in Toronto & GTA

  • Scope of Work – basement waterproofing projects can include a number of other services – window well installations, basement underpinning (floor lowering), etc. The more services included under basement waterproofing, the higher the cost will be.
  • Depth of the Foundation – foundation depths in Toronto generally range between 5 and 8 feet. Deeper foundations require more labor and materials, which results in a higher cost of basement waterproofing.
  • The Extent of the Damage – before we start your project, our team will examine your foundation to determine the extent of existing damage. Small basement wall cracks can be repaired using relatively inexpensive materials such as epoxy injection. More extensive foundation repairs (such as foundation reinforcement) are more complex and increase the cost of basement waterproofing.
  • Materials – if your basement waterproofing projects only involve foundation crack repairs cost of materials will be lower compared to interior waterproofing or exterior waterproofing.
  • Foundation Depth: The depth of your foundation will alter the overall waterproofing cost as it affects the complexity and scope of the work. Deeper foundations can increase the amount of labour, materials, and excavation required for exterior waterproofing methods. Foundation depths in Toronto generally range between 5 and 8 feet. Deeper foundations require more labor and materials, which results in a higher cost of basement waterproofing.
  • Type Of Waterproofing: The type of basement waterproofing you choose will impact the final cost since each method has different labour and material expenses. For example, excavation, sump pump installations, and backwater valve installations are all priced differently and therefore alter the final cost.
  • Addressing Cracks: Foundation, wall, floor, and/or ceiling cracks need to be addressed before waterproofing your basement. If gaps or cracks are left untreated, interior and exterior waterproofing will be ineffective. The methods used to resolve these problems will alter the final cost.
  • Labour and Installation: Exterior and interior waterproofing have different job requirements. This can affect the number of labourers needed and the time to complete the job. Complex jobs may need more skilled tradespeople, which can be more expensive.
  • Property Size & Location Factors: The size and layout of your basement influence the type and quantity of materials needed as well as the amount of labour required. Your basement’s ease of access, proximity to utilities, and the environment, such as soil type and condition, also affect the complexity of work and subsequent costs.

Frequently Asked Questions

While interior waterproofing is less expensive initially, exterior waterproofing is often more cost-effective in the long-term. Exterior forms of waterproofing typically need less maintenance than interior ones.

Yes, both interior and exterior waterproofing methods require long-term maintenance. Interior waterproofing expenses can be higher than exterior methods as sump pumps and other drainage systems will need to be cleaned occasionally and possibly repairs over time to fix wear and tear.

It’s not recommended to attempt basement waterproofing on your own, especially any form of exterior waterproofing, as this can lead to more extensive and costly damages. Some waterproofing methods, such as applying sealant and epoxy resins to fill and seal cracks or gaps in your basement walls, can be done DIY. However, if the cracks or gaps are a result of a large and more complex issue, failing to have your basement properly assessed can lead to bigger problems with more expensive repairs.

Potential waterproofing disadvantages include:

  • High costs
  • Landscaping disruptions
  • Ongoing maintenance
  • Removal and replacement of existing basement finishes

Yes, a sump pump can increase your energy bills if it runs frequently. It’s important to have your sump pump installed by professional waterproofing experts, as faulty pumps will have to work harder to be effective, which can result in higher hydro expenses.

The least expensive form of basement waterproofing is the application of waterproof paint. The average cost of waterproof paint is $1 to $2 per square foot. However, this method isn’t nearly as effective as others and will not resolve issues with your foundation, leaks, or flooding.
