There are many solutions when it comes to waterproofing your basement, making sure your biggest investment – your home – is protected against rain, snowfall, or storms that Mother Nature throws your way. Let Canada Waterproofers Georgetown take care of that wet basement or prevent it from even happening. Let’s talk. For us, consultation means listening to your concerns or objectives, and taking into account the uniqueness of your home. Let’s start with a free on-site assessment and take it from there. We 100% guarantee your satisfaction on all of our services, all of which have a transferable warranty – even if you sell the home.

Basement leaks can lead to a full-on wet basement that can leave behind mildew and mould. That can result in serious health problems. Get ahead of that problem while saving yourself thousands of dollars in home repairs. Contact Canada Waterproofers Georgetown for all of your waterproofing needs.


There are many ways your basement can be exposed to water leaks. If the piping is old and worn out it can cause condensation and erosion, leading to pipes bursting. 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 foundation walls.

We recommend exterior waterproofing. Our blue skin is a solution that can keep water and moisture away from your foundation walls and eliminate the potential of a leak. The process involves relieving the pressure by installing protective layers on the walls (blue skin), along a system of weeping tiles and sump pumps, to ensure any accumulation of water or moisture can be redirected away from the foundation, allowing the surrounding soils to settle and dry. In this scenario you are set – your home will be safe and dry.

Moisture is an enemy to any home, sparing no part of it. It can cause damage to your bricks, timber, concrete and cost you thousands of dollars to repair or replace. When these damages occur, not only is your home’s health at risk, but your health, and your family’s health, is at risk as well. Although it may seem harmless, mould spores can travel through your home, creating serious air quality issues. Waterproofing your basement will ensure this is never an issue.


If you’re looking for a more affordable solution for waterproofing your basement, interior waterproofing is ideal. Sometimes the only option available is interior waterproofing. Not all homes can accommodate exterior waterproofing (neighbouring homes may be located too close together). Exterior waterproofing also costs more.


Many companies like to tell you that interior waterproofing is the best option. They will tell you it protects your foundation walls from damage, but the truth is a little different.
Although you may not have any other option but to waterproof from the inside, at Canada Waterproofers Georgetown, we always like you to go into your waterproofing project with your eyes open.

Inside waterproofing will stop water from entering into your finished basement, allowing you to enjoy a dry living space. However, there will always be a little bit of water trapped behind the membrane, which will over a very long time deteriorate your walls.

When using the wrong insulation and vapour barrier after an interior waterproofing system is installed, you then run the risk of condensation building up, which could mean mould behind your walls. We like to call this the “mould sandwich”.


A mould sandwich is when you have two waterproofing impermeable layers, like a waterproofing membrane and vapour barrier, that doesn’t let moisture escape, allowing your rock wool insulation to become saturated, which will turn to mould.


After interior waterproofing is complete, all you have to do is have it spray foamed during the refinishing of your basement. That’s it. Spray foam becomes its own vapour barrier, which eliminates that mould sandwich. So instead of having two waterproof membranes you get a continuous membrane, as the foam sticks to the waterproofing membrane and seals and insulates.

Interior waterproofing was introduced into area homes many years ago. It’s an effective way of keeping GTA homes dry and free from leaking.


Interior waterproofing has become popular in the last decade, as people are finishing basements more often in Toronto and the surrounding areas. Lots of homes in the Georgetown community are close to one other and the only way to protect these homes is to install interior waterproofing.

The average cost to finish a basement is around $50,000. That is why it is very important to have your basement waterproofed prior to spending this kind of money. If a basement is finished with drywall and a leak occurs, not only does all the drywall have to be redone but also the flooring, baseboards and everything else, so that all the mould can be removed. It can be a real, expensive mess.

A new waterproofing system can then be installed prior to refinishing your basement. Refinishing would normally cost an additional $20,000 to $30,000, if you were faced with replacing and repairing water damage.


Interior waterproofing is much more cost effective than exterior waterproofing. That’s why many people opt to take the internal route.

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

The best way to find out how much a project like this would cost is to give us a call and ask us for a free onsite assessment.


Insurance companies are great for many things, but if you mention to the insurance adjuster there was prior seepage or leaking after your basement gets flooded, which includes window wells, a cracked foundation that leaks, or a sump pump failure, then you’re on your own. They won’t help you.
Give your insurance company a call to add extra coverage so that you can be more protected.
