    Waterproofing, Foundation Repair, Underpinning, Concrete Specialties Our Construction Services Waterproofing We have all heard the horror stories. It’s spring. The snow is melting, the rain is heavy and the basement floods. The reasons for a wet, or even damp, basement, can be many. Heavier rainy seasons and milder winters are causing the ground to freeze and thaw several times before spring. This contributes to constant shifts in the ground and wrecks havoc on cracked or weak foundations. As torrential rain downpours become more commonplace, these compromised foundations simply cannot keep the water out. more about wet basements .... Regardless of the reason for a home’s wet basement, Aquashield Waterproofing will assess each issue and identify the most suitable solution to fix the problem(s). more about Aquashield’s specific waterproofing techniques ... Check out our Video! (attention dial-up users: LARGE file 7.5MB) Foundation Repair There are many different ways to repair foundations depending on the type of foundation, the source of the problem and the level of damage. In many cases, the foundation wall can be repaired with relatively simple and straight-forward techniques. Depending upon the specifics of the issue and the accessibility of the problem area, repairs can be completed from either the outside or the inside of the residence. In extreme cases, homeowners may need to consult with a structural engineer to confirm whether a home’s foundation is sound or if the foundation may need to be rebuilt. In other cases, another foundation wall built next to the original will provide the necessary reinforcement. Each waterproofing and foundation repair company will have its own preferred methods. Typically, however, the solution is simple. Some companies, however, will sell homeowners on extremely expensive methods, technology and materials. At Aquashield Waterproofing we will not complicate things unnecessarily. We will work hard to identify the most effective and cost-efficient solution for your home’s foundation issues. more about foundations & their problems ... Underpinning When a basement requires more ceiling height or the foundation needs to be strengthened and stabilized, both can be achieved through underpinning. This process involves carefully digging out small sections of the ground below the existing foundation wall in a 1-2-3 sequence that will add depth and stability. To ensure continued support for the structure, it is not safe to underpin an entire length of a wall in one go. The work must be done in sections. A small section, below and beside the existing foundation is excavated and temporary supports may be installed to support the main weight-bearing walls during this process. The excavated sections are then filled with concrete to create a new foundation or series of concrete footings beneath the original. This process of underpinning is an effective method to extend the depth and width of support offered by the original foundation. Once the foundation wall is lowered, a new concrete floor can be poured, providing additional height in a basement. Concrete Specialties Walkouts, driveways and more In addition to waterproofing and foundation repair, Aquashield Waterproofing’s services extend to a variety of specialty concrete projects, including basement walkouts, driveways and parging.

What basement waterproofing services are available in Toronto?

Pros can waterproof basements from the interior, the exterior, or using a combination of techniques. The right service depends on whether you need full waterproofing or just touch-ups.

Here are some common basement waterproofing services in Toronto:

  • Installation of interior drainage systems: a perimeter drain installed along the interior footing collects and redirects water to a sump pit for removal.
  • Sump pump installation and replacement: often handled by a plumber, a pump installed in the sump pit removes accumulated groundwater and directs it away from the foundation.
  • Exterior waterproofing: excavation around the foundation allows for membrane application and drainage board installation to block water at the source.
  • Crack injection: epoxy or polyurethane foam is injected directly into foundation cracks to seal them against water intrusion.

No matter your needs, it’s easy to find basement waterproofing pros near you who can help. Just post your project on HomeStars now, and available contractors in your area can reach out!

What are the average costs of basement waterproofing pros in Toronto?

Basement waterproofing costs vary widely depending on the method, the size of the foundation, and where repairs are concerned, the extent of the damage. Labour typically runs between $50 and $150 per hour, depending on the service and complexity of the job. Materials and equipment, such as excavation machinery, may add additional costs.

Typical costs for common basement waterproofing services in Toronto:

  • Installation of interior drainage systems: between $3,000 and $10,000 for a full perimeter system in an average-sized basement
  • Sump pump installation and replacement: between $500 and $2,000 depending on pump type and whether a backup system is included
  • Exterior waterproofing: between $10,000 and $30,000 depending on foundation size and depth of excavation required
  • Crack injection: between $300 and $800 per crack depending on length, depth, and material used

HomeStars tip: To ensure you get the most accurate costs for Toronto, make sure to get everything written down in an itemized quote. This avoids misunderstandings and supports transparency and clear communication for both you and the contractor.

FAQ: Common questions about basement waterproofing in Toronto

How long does basement waterproofing last in Toronto?

Most professional waterproofing solutions in Toronto are designed to last 10 to 25 years depending on the method used and the quality of installation. Sump pumps typically require replacement every 7 to 10 years.

Will waterproofing fix existing mould in my basement?

Waterproofing addresses the source of moisture but will not remove mould that has already formed. A separate mould remediation service is typically required before or after waterproofing work is completed.

What if my basement waterproofing project in Toronto requires excavation?

Exterior waterproofing projects in Toronto often require excavation around the foundation, which adds complexity, time, and cost to the overall job. It is important to work with pros who can coordinate this process effectively. Local excavation specialists are available on HomeStars to walk you through what to expect and collaborate with your preferred basement waterproofing pro.

Does homeowner insurance cover basement waterproofing in Toronto?

In most cases, standard home insurance policies do not cover waterproofing as it is considered a maintenance issue rather than sudden damage. However, water damage resulting from a specific event such as a burst pipe may be covered. It is worth reviewing your policy or speaking with your insurance provider for clarification.

How do I know if a basement waterproofing pro is right for my project?

Not all waterproofing projects are the same, and finding a pro with the right experience for your specific situation is important. Reading reviews from homeowners who have had similar work done can help you make a more informed decision. Browse basement waterproofing pros on HomeStars to compare ratings and reviews from real homeowners in Toronto.
