We don’t need an Al Gore documentary on the environment to tell us the climate is changing. Just look out the window. The climate crisis is impacting weather patterns and the water cycle in different ways. A higher rate of evaporation around the globe means more heavier rain and snow events.

That can mean home owners feel vulnerable, especially those people unsure what kind of waterproofing system they have installed in their house, or if there’s one installed at all.

A basement flood has an enormous financial impact when talking about potential repairs, especially if that water turns to mould and mildew. To think it could have been avoided with a waterproofing system would be too unbearable to even contemplate. What about the personal items – photos, work files, family heirlooms – that would be ruined in the event of a flood?

Knowledge is power. Call Canada Waterproofers Clarington for a free, no-obligation assessment of the waterproofing status of your home. It all starts with a simple conversation.

We are homeowners as well, so we understand what “home” means.

We offer both exterior and interior waterproofing options – all dependant on your unique situation. Our technicians are licensed and insured. We use only the latest in materials and technology. We have a fully transferrable, 25-year warranty to back up our work. And we bring over 25 years of experience in the community doing this.

We operate in an industry where integrity in business sometimes is lacking. Canada Waterproofers Clarington offers both completive pricing, as well as integrity and transparency when talking about the process.


Houses are sometimes built within a high water table, which means without a proper waterproofing system the water surrounding the basement will enter through the space where the wall meets the floor, and also enter through cracks in the floor. That’s especially true if there is a major rain storm, or a major snow melt.

Another example is when basements are excavated. New soils that are filled around the new foundation will be looser than the surrounding undisturbed ground. Water collects much faster in loose soil than undisturbed soil, so moisture builds up quick against the new foundation wall – and wears them down over time.

Another culprit is a window well.

Window wells have a drainage tube, which connects to the existing weeping tile system around the house. Sometimes these window well drains will get clogged with years of debris, and if combined with bad grading around the house which directs water towards your window, the window well will fill up like a bathtub. Water will enter through the window itself, causing a large amount of damage.

It is very important to have your window wells checked by a specialist on a regular basis so that you protect your property from serious damage from this kind of source.

Waterproofing your basement from the outside is an effective way to get at flooding at its source, to protect what will likely be one of the biggest investments you will make in your life.


The only way to relieve this pressure is to install protective layers on the walls, as well as a system if weeping tiles and sump pumps, so the accumulation of water can be re-directed away from the foundation of your home, allowing surrounding soils to eventually dry and settle.

Whether you go for an exterior solution or one inside your foundation walls, it comes down to a few factors. We like to waterproof from the outside, because it tackles the water leakage issue at its source – before it seeps through the foundation walls. Interior waterproofing (including using sump pumps and backwater valves) is more of a water management solution.

However the end game is a dry basement – and the interior option more than accomplishes that. Interior waterproofing is also less expensive than exterior waterproofing. Also, in some instances the home is located too close to a neighbour’s home, or the soil surround the foundation is too wet –  in both cases we can’t excavate.

A leaking foundation may seem like a big job to fix, but we can assure you that with the right waterproofing method your basement will stay dry.

Give the pros at Canada Waterproofers Clarington a call. We’ll take a look at your home and come up with the best solution for your particular situation.


Many homeowners look at their basements as an opportunity to renovate, creating a new living space for the family, or a rental income opportunity – with a separate entrance, bathroom and kitchen. Depending on whether you do it yourself or bring in contractors, the cost to renovate a basement can top $50,000. It depends on what you decide to do.

That’s why, if you are spending this kind of money, it is so important to waterproof your basement – whether you opt for exterior waterproofing, and the excavation involved in that, or go for the inside option. A water-damaged basement – repairing floorboards, baseboards, drywall, everything – could cost you an additional $20,000 to $30,000.


Interior waterproofing is much more cost-effective than exterior waterproofing, and that’s why many people go in this direction.

Interior waterproofing ranges from $65 to $125 per foot. The determining factors are concrete thickness, height of the basement, amount of footage, commercial or residential, and accessibility.

Exterior waterproofing costs anywhere between $90 and $600 per foot, depending on factors like accessibility, the depth needed to excavate, and the space between houses, and if it’s a commercial and residential property.

The best way to find out how much a project like this would cost is to give Canada Waterproofers Clarington a call so we can give you a free onsite assessment.
