How to waterproof your basement permanently

What do you use your basement for?

Playing board games and watching movies? Storing old furniture and boxes of papers? Or do you hardly venture down into your basement at all?

No matter how much or how little time you spend in your basement, proper waterproofing is crucial to prevent water-related damage.

Sadly, it’s easy to overlook the importance of proper waterproofing in your basement, particularly if you can go months without seeing it. You might miss a crack in a wall or a leaking pipe if you don’t pay attention to small details — but either could create a serious risk to your home.

Fixing a leaky basement and waterproofing it effectively can seem like a daunting task, though it’s actually simpler than you may assume.

As we have years of experience in helping property-owners with basement waterproofing across Toronto, we’ve written the following post to help you protect your property against water damage.

Why is it so important to fix a leaky basement?

First, let’s be clear on why you should fix your leaky basement in the first place.

Moisture creates an ideal breeding ground for bacteria that could spread throughout your home. Mold also forms in damp spaces, so it’s a common issue in leaky basements. And mold can be a real problem when it’s black.

Mold can also compromise the structural integrity of your home and prove harmful to people with allergies or asthma. You may spot mold growing on everything from drywall to carpets, so it’s vital to remove it as soon as you spot it

Wet basements can attract a variety of insects and creatures that may damage goods in storage too. And dry rot can destroy wood, weakening wall paneling, stairs, etc.

Fortunately, proper basement waterproofing can help you avoid these issues and create a cosy, comfortable space you want to visit more often.

Plus, implementing quality basement waterproofing in your home could increase its value if you plan to sell up: prospective buyers may consider the decreased risk of floods and moisture damage a big bonus, with the potential to save money in the future.

What are the most important steps for basement waterproofing that lasts?

Install effective interior drainage systems to prevent floods

Fitting an interior drainage system is one of the most popular and effective methods of basement waterproofing.

This involves creating a trench that runs around the outside of the basement floor. As a result, leaks caused by cracks or holes in your walls will run to a drain or a sump pump that moves water to a designated external space.

If your basement has flooded in the past, you know how frustrating and time-consuming it can be to fully drain. But a well-made interior draining system can cut the risk of water buildup significantly.

It’s highly recommended that you trust a professional to create a drainage system for you. It can be time-consuming and complicated for beginners.

Apply exterior waterproofing to keep moisture on the outside

You can coat your property’s exterior walls with special materials (typically membranes and polymers) to waterproof your basement.

Exterior waterproofing helps to protect your basement from the outside and reduces the likelihood of moisture seeping in through your walls. You may miss tiny cracks or holes that could allow water to enter your property, but a waterproofing coating will cover them effectively anyway.

You might need to replace coatings over time, though, to maximize their performance.

Use waterproof sealant on basement walls and floor

Tending to your interior walls is just as important as coating your home’s exterior. Apply a waterproof sealant to your basement walls and floor to stop moisture seeping through.

However, sealants are designed for direct application to bare masonry rather than painted walls. Your basement will be at risk of moisture damage if you use a sealant incorrectly, so it’s worth your while to get it right from the start.

That means you might need to remove paint carefully from walls and clean them before you apply your chosen waterproof sealant. And check them for signs of cracks or decay that could allow moisture to get inside.

You can then paint (or repaint) over the sealant to revitalize your basement, once the walls and floor have dried.

Invest in a dehumidifier to keep your basement dry

Installing a dehumidifier in your basement is a simple and effective way to keep the space dry. They extract moisture from the air to stop it building up, creating damp, and ruining your walls and upholstery.

Dehumidifiers tend to be user-friendly and simple to empty. They’re also widely available at a range of prices, so you should be able to find one at a cost that suits you.

Check potential external flaws that could create waterproofing issues

One tip we often share when providing basement waterproofing in Toronto solutions: assess outdoor spaces for potential issues.

For example, your gutters are likely to overflow if they become blocked by debris (leaves, dirt, moss, etc.) so check them regularly — especially if you’re expecting heavy downpours. Look for leaks in your gutters and downspouts too

Assess your basement windows for cracks in the frames or gaps surrounding the pane, particularly if they haven’t been replaced or repainted in a long time. Wood can become weaker and less effective at keeping moisture out of your home when exposed to the elements for years.
