Professional Basement Waterproofing In Toronto

Case Study Example

We recently worked with a Toronto homeowner who had started experiencing basement flooding a few years ago. What began as occasional dampness has escalated into yearly floods, despite installing a smart sump pump, they were still suffering from occasional flooding, dampness, and the tell-tale musty odour.

Our service began with a FREE basement inspection, allowing us to discuss the homeowner’s concerns and properly evaluate their basement. After a thorough assessment, it became clear that while their sump pump was a good initial step, an exterior waterproofing solution was necessary. The entire exterior waterproofing process, including excavation, took our contractors approximately two days to complete. While two days of significant work might seem like a commitment, it translates to a minimum of 25 years of protection – definitely a worthwhile investment.

These homeowners are not alone – 1 in 10 homeowners have experienced a wet basement, with 85% of flooding issues resulting from bad drainage! Climate change and its effect on the water cycle are not making this situation any better. With more rainfall and increasing temperatures, it is so important to make sure you protect your investment with professional waterproofing services.

Signs You Should Waterproof Your Basement

After years of waterproofing homes throughout Toronto and the GTA, our contractors recognise the signs that indicate your basement is leaking. Here are the most common signs that your basement is leaking:

  • Standing water/puddles: If you notice water pooling on your basement floor, that means water is definitely seeping in from the outside. Even small puddles tend to blow up into major problems if left unaddressed.
  • Musty odours: A damp, musty smell in your basement is usually because of moisture that encourages mould and mildew to grow. This smell can persist even when visible water is not present.
  • Mould or mildew: Mould grows well in damp environments, and if it is growing in your basement, then that is a sure sign of moisture issues.
  • Efflorescence on walls: A white, chalky residue on your basement walls is a sure sign that water seepage is occurring through the foundation, carrying mineral deposits along with it. This is usually one of the first early warning signs of water intrusion.
  • Peeling paint/wallpaper: Moisture behind walls can cause paint to bubble and peel or make wallpaper loosen. This cosmetic damage can be an indication of a more serious underlying issue.
  • Warped doors/flooring: Swelling or warping in doors, hardwood floors, and baseboards could indicate continuous subjection to water exposure.

Basement Waterproofing FAQs

The durability of a waterproofing solution is influenced by several factors, including the quality of materials utilized, the extent of water issues addressed, and the regularity of maintenance. High-quality materials and expert installation can ensure that a professional waterproofing solution lasts for an extended period, often ranging from several years to multiple decades. However, it’s essential to conduct periodic inspections and maintenance to ensure the continued effectiveness of the waterproofing system over time. Regular upkeep can identify and address any emerging issues promptly, thereby extending the lifespan of the waterproofing solution and preserving the integrity of your basement.

The best basement waterproofing method depends on factors such as the type of foundation, severity of water issues, and budget. Common effective methods include exterior waterproofing, interior drainage systems, and waterproof coatings or sealants. Exterior waterproofing involves creating a barrier outside the foundation walls to prevent water intrusion. Interior drainage systems, like sump pumps and French drains, manage water inside the basement. Waterproof coatings or sealants add an extra layer of protection to basement walls and floors. Consulting with a professional can help determine the most suitable method for your specific needs.

Waterproofing a basement from the inside involves several steps. First, identify and repair any existing leaks or cracks in the walls or floor. Next, install an interior drainage system such as a sump pump or French drain to manage water buildup. Apply a waterproofing membrane or sealant to basement walls and floors to create a barrier against moisture intrusion. Proper insulation and ventilation also help prevent condensation and moisture buildup inside the basement.

The cost of waterproofing a basement in the Greater Toronto Area varies depending on factors such as the size of the basement, the extent of water issues, and the chosen waterproofing method. DGI charges $6 to $8 per sq. ft. depending on materials and company.

No, waterproofing is necessary for homes of all ages. Even newer homes can experience water infiltration due to poor drainage, foundation cracks, or faulty construction. Regular inspections and preventive waterproofing measures are essential to maintain the integrity of any property.

Yes, waterproofing your basement can increase your home’s value significantly. A dry, functional basement adds usable square footage to your home, making it more appealing to potential buyers and enhancing its market value.

While waterproofing can be performed year-round, it is often recommended to schedule projects during dry weather conditions. Dry weather allows for optimal curing of sealants and coatings, ensuring the effectiveness and longevity of the waterproofing solutions.
